Generic Name
colchicine (KOLE-chih-sene)
Type of Drug Antigout medication.
Prescribed For
Prevention and treatment of gouty arthritis; also prescribed for Mediterranean fever; chronic progressive multiple sclerosis; cirrhosis of the liver; biliary cirrhosis; Beh~et’s disease’, pseudogout (a condition caused by calcium deposits); amyloidosis; very low blood-platelet count (also known as ITP); skin reactions, including scleroderma, psoriasis, Sweet Syndrome, and other conditions; and nerve disability associated with chronic progressive multiple sclerosis.
General Information
While no one knows exactly how colchicine works, it appears to help people with gout by reducing the inflammatory response to uric acid crystals that form inside joints and by interfering with the body’s mechanism for making uric acid. Unlike drugs that affect uric acid levels, colchicine does not block the progression of gout to chronic gouty arthritis; it will, however, relieve the pain of acute attacks and lessen the frequency and severity of attacks. It has no effect on other kinds of pain.
Cautions and Warnings
Do not use colchicine if you are allergic or sensitive to any of its ingredients or you suffer from any serious blood, kidney, liver, stomach, or cardiac condition.
Vomiting, abdominal pain, diarrhea, nausea, kidney damage, and blood in the urine may occur with colchicine, especially at maximum doses. This can worsen existing gastrointestinal (GI) or other conditions. Stop taking the medication and call your doctor if you develop one of these symptoms.
She weakness that people develop while taking colchicine is frequently related to high levels of colchicine in the blood caused by poor kidney function and improves without treatment 3-4 weeks after the drug is stopped. This reaction is often mistaken for other conditions.
Periodic blood counts should be done if you are taking
colchicine for long periods of time.
Colchicine interferes with the absorption of vitamin B12 by af-
fecting the lining of the GI tract.
Colchicine may affect the process of sperm generation in men. The safety and effectiveness for use by children have not been
established.
Possible Side Effects
V Common: vomiting, diarrhea, and abdominal pain may occur if you take maximum doses of colchicine for an acute gout attack. You may also experience severe diarrhea, kidney and blood-vessel damage, blood in the urine, and reduced urination.
✓    Less common: hair loss, rash, appetite loss, and muscle and nerve weakness.
✓    Rare: with long-term colchicine therapy—reduced whiteblood-cell and platelet counts, nerve inflammation, blood-clotting problems, rash, unusual bleeding or bruising, tingling in the hands or feet, red or purple spots under the skin, and other reactions. Colchicine may interfere with sperm formation. Contact your doctor if you experience any side effect not listed above.
Drug Interactions
•    Colchicine interferes with the absorption of vitamin B12.
•    Colchicine may increase sensitivity to central-nervoussystem depressants, such as sedatives and alcohol.
•    The following drugs may reduce colchicine’s effectiveness: anticancer drugs, bumetanide, diazoxide, thiazide diuretics, ethacrynic acid, furosemide, mecamylamine, pyrazinamide, and triamterene.
•    Taking phenylbutazone with colchicine increases the risk of side effects.
•    Mixing the anitiiofic clarithromycin with colchicine can lead to colchicine toxicity, especially in the elderly and those with kidney disease.
Food Interactions None known.
Usual Dose
Acute Gout Attack: 1-1.2 mg. This dose may be followed by 0.51.2 mg every 1-2 hours until pain is relieved or nausea, vomiting, or diarrhea occurs. The total dose needed to control pain and in-
flammation during an attack varies from 4-8 mg.
Gout Prevention: 0.5-1.8 mg daily. In mild cases, 0.5 mg or 0.6 mg may be taken 3-4 days a week.
Familial Mediterranean Fever: 1-2 mg a day.
Cirrhosis of the Liver: 1 mg a day for 5 days each week. Biliary Cirrhosis: 0.6 mg twice a day.
Amyloidosis: 0.5 mg 1-2 times a day.
Behqet’s Disease: 0.5-1.5 mg a day.
Pseudogout: 0.6 mg twice a day.
ITP: 1.2-1.8 mg a day for 2 weeks or more.
Scleroderma: 1 mg a day.
Sweet Syndrome: 0.5 mg 1-3 times a day.
Other Skin Disorders: up to 1.8 mg a day, depending on the specific condition.
Overdosage
The lethal dose is estimated at 65 mg, although people have died after taking as little as 7 mg at once. Usually 1-3 days pass between the time that an overdose is taken and symptoms begin. Overdose symptoms start with nausea, vomiting, stomach pain, diarrhea—which may be severe and bloody—and burning sensations in the throat or stomach or on the skin. If you think you are experiencing overdose symptoms, contact your doctor immediately, or go to a hospital emergency room. ALWAYS bring the prescription bottle or container.
Special Information

Stop taking maximum doses of colchicine as soon as gout pain is relieved and reduce your dose to a maintenance level if your doctor has prescribed it for gout prevention. Stop taking the drug entirely and contact your doctor at the first sign of nausea, vomiting, stomach pain, or diarrhea.
If you forget a dose of colchicine, take it as soon as possible. If it is almost time for your next dose, skip the dose you forgot and continue with your regular schedule. Do not take a double dose.
Special Populations
Pregnancy/Breast-feeding: colchicine can harm the fetus. Pregnant women should not take it unless the potential benefits clearly outweigh the risks.
It is not known if colchicine passes into breast milk. No problems with nursing infants are known, but nursing mothers who must take colchicine should consider using infant formula.
Seniors: Seniors, especially those with renal, hepatic, gastrointestinal, or heart disease, are more likely to develop side effects and should use colchicine with caution.

Type of Drug
Contraceptives
Plan B
Prescribed For
Prevention of pregnancy, endometriosis, excessive menstruation, and cyclic withdrawal bleeding. Ortho Tri-Cyclen and Estrostep may be prescribed for moderate acne in women over age 15.
General Information
Contraceptive drugs are synthetic hormones containing either progestin or a progestin-estrogen combination. The overall effects of any contraceptive are influenced by the interaction of all active ingredients, including those Huth -&))Otogenic and anti-estrogenic aqtk%(kkj.’%tte drugs are similar to natural female hormones, which cannot be used as contraceptives because very large dosages would be required. Synthetic hormones are more potent and are effective at smaller dosages. Contraceptive drugs work by preventing sperm from reaching the unfertilized egg, preventing the implantation of a fertilized egg in the uterus, or preventing ovula-tion (the release of an unfertilized egg from the ovaries). They prevent acne by balancing hormone levels.
When properly used, hormonal contraceptives can be 97-99% effective at preventing pregnancy. These products vary in their etfectiveness, and in the amount and type of estrogen or progestin used. The side effects of these drugs tend to increase with the amount of hormone they contain. While low hormone dosages are preferred, contraceptives with the smallest amounts of estrogen may be less effective in some women than others.
Single-phase products provide constant levels of estrogen and progestin throughout the entire month-long pill cycle. In 2-phase combinations, the amount of estrogen remains at a steady low level throughout the cycle, while progestin levels increase and then decrease. This variation in progestin allows normal changes to take place in the uterus. Three-phase products are meant to simulate the normal hormone cycle and reduce breakthrough bleeding. Throughout the cycle, estrogen levels remain the same while those of progestin change to create a 3-part wave pattern. The amount of estrogen in 3-phase products is considered low. Breakthrough bleeding may occur with the older combination products from day 8 through 16 of the cycle.
The mini-pill, a progestin-only product, may cause irregular menstrual cycles and may be less effective than estrogenprogestin combinations. Mini-pills may be recommended to older women or women who should avoid estrogens (see “Cautions and Warnings”).
The contraceptive patch releases small amounts of progestin and estrogen continuously over 3 weeks. The medication is absorbed into the blood vessels just below the skin. The patch works in the same way as contraceptive pills do.
The vaginal ring releases small amounts of etonogestrel, a progestin, and estradiol, an estrogen, in the vaginal canal over 3 weeks. The combination prevents pregnancy in the same way as combination pills do but may be less effective than contraceptive pills because some people find them harder to use.
Most contraceptive drugs are designed to simulate a normal Mt%VwM cycle. By not taking the hormones 1 week out of the month, you continue to have your regular period. In fact, these products are often used to stabilize a woman’s period. Two products, Seasonale and Seasonique, come in an 84-pill packet and are taken once a day for 3 months. This means you will only have your period once every 3 months. Another, Lybrel. is designed to be taken every day, eliminating monthly menstruation. Drosperinone, the progestin found in Yasmin and Yaz, has been found to relieve Premenstrual Syndrome (PMS) symptoms in addition to acting as an effective contraceptive hormone.
Levonorgestrel, a progestin, is used in implants that provide effective contraception for up to 5 years after surgical implantation under the skin of the upper arm or inside the uterus. Levonorgestrel implants should be replaced at least once every 5 years. Etonorgestrel implants are effective for 3 years. Implants can be removed at any time, reversing the contraceptive effect. The progestin intrauterine inserts provide effective contraception for about 1 year. The implant and intrauterine systems contain the same hormone found in the mini-pill and are associated with many of the same side effects and precautions as oral contraceptives.
Emergency contraceptives (sometimes referred to as the “morning-after pill”) contain high doses of estrogen and progestin. They are intended for use only after contraceptive failure or unprotected intercourse. They should never be taken by a pregnant woman.
Contraceptive drugs in any form are associated with risks. These risks are greatest in women over age 35 who smoke and have high blood pressure.
Cautions and Warnings
Do not take contraceptives if you are allergic or sensitive to them or any of their ingredients.
The risk of breast cancer may be slightly higher among current and recent users of combination oral contraceptives. This risk appears to decline after contraceptive use is stopped and is gone by 10 years after stopping combination contraceptive products. Breast cancers found in contraceptive users tend to be less advanced than those in non-contraceptive users.
You should not use contraceptive drugs if you are or might be pregnant, have had blood clots in veins or arteries, stroke, any blood-coagulation disorder, known or suspected cancer 0 the breast, sex organs, or liver. Products With more estrogen, or those t43.t jmmdr3higher sustained blood levels of estrogen, such as the contraceptive patch, are more likely to be associated with an increased risk of life-threatening blood clots.
Contraceptive drugs may cause eye lesions. Call your doctor at once if you develop visual difficulties of any kind.
Women taking the combination products Seasonale and Seasonique will have their period only once every 3 months and those taking Lybrel will not have a regular monthly period. It is absolutely essential for you to verify you are not pregnant if you think you may be pregnant for any reason.
The risks of contraceptive drugs increase if you are physically immobile or have asthma; cardiac insufficiency; epilepsy; migraine; kidney problems; a strong family history of breast cancer; benign breast disease; diabetes; endometriosis; gallbladder disease or gallstones; liver problems, including jaundice; high blood cholesterol; high blood pressure; estrogen or progestin intolerance; depression; tuberculosis; or varicose veins.
There is an increased risk of heart attack in women who have used contraceptive drugs for more than 5 years, or who are between age 40 and 49 and have other coronary risk factors such as smoking. obesity, high blood pressure, diabetes, and high blood cholesterol. This risk remains even after the medication is stopped.
Smokers in their mid-30s or older who use contraceptive drugs are 5 times more likely to have a heart attack than nonsmokers taking contraceptives and 10-12 times more likely to have a heart attack than nonsmokers who do not use the pill. Death due to circulatory disease also increases substantially in smokers taking contraceptive drugs, especially in women at least 35 years old. The risk of stroke is also increased in this group. Heavy smokers (more than 15 cigarettes a day) should not use hormonal contraceptives.
Women with a history of headaches, high blood pressure, or varicose veins should avoid estrogen-containing products, as Should older women and those who have experienced estrogen side effects.
Contraceptive drugs may mask the onset of menopause. Progestin-only products are associated with an increased risk of blood-clotting problems.
The progestin in Yasmin and Yaz raises blood potassium levels. Women with kidney, liver,,Dy adrenal gland disease should use eittlp_C pIrjdUcj with caution.
Intrauterine inserts have been associated with an increased risk of pelvic inflammatory disease (PID). The highest risk usually occurs within the first 20 days after insertion. Do not use intrauterine inserts if you have had an ectopic pregnancy.
Toxic Shock Syndrome has been associated with tampons, some barrier contraceptives, and the vaginal ring, although there is no proof that the product was the cause of the infection.
Possible Side Effects
♦ Common: Common side effects often result from using a product that is poorly suited to your body chemistry. Determining the right amount and type of hormone often minimizes these effects. If you are taking too much estrogen, you may experience nausea, bloating, high blood pressure, migraine, excess cervical mucous, skin discoloration, colon polyps, water retention, and swelling, or breast fullness or tenderness. Too little estrogen may cause early or mid-cycle breakthrough bleeding, spotting, or reduced periodic flow. Too much progestin is associated with weight gain and increased appetite, tiredness or fatigue, low periodic flow, acne, depression, breast regression, and androgen-related side effects (acne, oily scalp, hair loss, or excess hair growth). Too little progestin may cause late breakthrough bleeding, excessive periodic bleeding, or missed periods.
✓    Less common: abdominal cramps, infertility after discontinuance of the drug, breast tenderness, weight change, headache, rash, vaginal itching and burning, general vaginal infection, nervousness, dizziness, depression, cataracts, changes in sex drive, hair loss, and increased sensitivity to the sun.
✓    Rare: Women who use contraceptive drugs are more likely to develop several serious conditions, including blood clots in the deep veins, stroke, heart attack, liver cancer, gallbladder disease, and high blood pressure. Women who smoke cigarettes are at much higher risk for some of these adverse effects. Contact your doctor if you experience any side effect not listed above.
brug Interactions
•    Ampicillin, barbiturates, bexarotene, bosentan, carbamazepine, chloramphenicol, efavirenz, fluconazole, griseofulvin, ketoconazole, neomycin, nelfinavir, nitrofuratoin, oxcarbazepine, phenylbutazone, phenytoin, penicillin drugs, protease inhibitor drugs for HIV, rifampin, rifapentine, statin drugs (atorvastatin and rosuvastatin), St. John’s wort, sulfa drugs, tetracycline products, and sedatives can make all contraceptive drugs less effective. Use backup birth control while taking these medications together.

Discuss mixing these medicines with your doctor. Dosage reductions may be needed.
•    Contraceptive drugs may increase the toxic liver effects of acetaminophen and reduce the drug’s effectiveness. Contraceptive drugs may increase or decrease the effect of anticoagulant (blood-thinning) drugs. Discuss the risks of this combination with your doctor.
•    Mycophenolate interferes with only those contraceptives that contain levonorgestrel (Alesse, Aviane, Lessina. Levora, Levlite, Lutera, Lybrel, Mirena, Nordette, Norplant II, Portia, Plan B, Seasonale, Seasonique, and Triphasil). Backup contraception is recommended.
•    Exenatide may reduce the effectiveness of contraceptive pills.
Take them at least 1 hour before an injection of exenatide.
•    Contraceptive drugs may reduce the effectiveness of clofibrate for elevated blood triglycerides, sulfonylurea drugs for diabetes, ursodiol for gallbladder disease, and pain relievers, including salicylates (aspirin).
•    Contraceptive drugs may increase blood-cholesterol levels and interfere with blood tests for thyroid function and blood sugar.
•    Acetaminophen may increase blood levels of ethinyl estradiol, a common contraceptive drug ingredient, increasing side effects and reducing contraceptive effectiveness.
•    Since Yasmin and Yaz raise blood potassium levels, nether should be used if you ate taking spironolactone or anD)ftr potassium-sparing diuretic, potassium supplements, angiotensin-converting enzyme (ACE) inhibitors, angiotensin receptor antagonists, aldosterone antagonists, heparin, non-steroidal anti-inflammatory drugs (NSAIDs), or other medications on a long-term basis that may further increase potassium levels.
•    Contraceptive drugs may interfere with the effects of insulin
for diabetes.
•    Acitretin interferes with the contraceptive effect of progestin-
only mini-pills. It is not known if it also interferes with combination contraceptive drugs.
Food Interactions
None known. Usual Dose
Single-Phase, 2-Phase, and 3-Phase Combinations: The first day of bleeding is day 1 of the menstrual cycle. Beginning on the first day of the cycle, take 1 pill a day for 20-21 days according to the number of pills supplied by the manufacturer. If menstrual flow has not begun 7 days after taking the last pill, begin the next month’s cycle of pills. Some manufacturers recommend starting the pills on a Sunday to make it easy to remember to take them. In this case, start taking your pills on the first Sunday after your period begins. If menstruation begins on a Sunday, take the first pill that day.
Seasonale: Take 1 pink tablet every day for 84 consecutive days. Do not skip a day. Then, take 1 white pill a day for 7 days. Then, start a new pill cycle. You may be pregnant if you do not have a period while you are taking the white pills.
Seasonique: Take 1 light blue-green tablet containng levonorgestrel and ethinyl estradiol daily for 84 consecutive days, followed by 7 days of ethinyl estradiol tablets. Do not stop if spotting or breakthrough bleeding occurs. Report prolonged bleeding to your doctor.
Progestin-Only Mini-Pill: Take 1 pill every day.
Contraceptive Patch: Apply a new patch to the thigh, abdomen, or arm. Remove the patch after 3 weeks and then reapply a new patch after 1 week. Be sure to always apply a new patch on the same day of the week. If you are switching from birth control pmts, apply the first patch on the same day you would start a new cycle of pills.
Vaginal Ring: Keep the vaginal ring in the vaginal canal for 3 weeks. Remove it and put a new one in 1 week later. If you did not use a hormonal contraceptive in the previous month, insert the ring between day 1 and day 5 of your cycle.
If you are switching from a combination birth control pill, insert the ring anytime during the week after you took your last pill but before you would have started your next cycle of pills. No additional contraception is necessary.
If you are switching from a mini-pill, insert the ring on the day after you take your last mini-pill.
If you are switching from a progestin implant or an IUD, insert the ring on the same day your implant or IUD is removed.
If you are switching from a progestin injection, insert the ring on the same day you would have received your next injection.
If you are switching from a progestin-only mini-pill, implant, injection, or IUD, use another form of contraception for the first 7 days after you insert the ring.
Emergency Contraception: Emergency contraceptive kits have only a few pills. They should be taken with a full meal. Take half the pills (1 or 2 depending on the brand you use) within 72 hours of unprotected sex, however they are most effective when taken within the first 24 hours. Take the rest of the pills 12 hours after the first dose. Emergency contraceptives reduce the risk of pregnancy by 75%.
The pregnancy test in the kit can be used to determine if you became pregnant earlier in your cycle or during a previous cycle. If the test is positive, consult your doctor before taking emergency contraception. If you vomit within one hour of taking either dose, contact your doctor.
Overdosage
An overdose may cause nausea and withdrawal bleeding in adult women. Overdose victims should be taken to a hospital emergency room. ALWAYS bring the prescription package.
Special Information
Use backup birth control to prevent pregnancy in the first 3 weeks after you begin taking contraceptive drugs.
Contraceptive drugs do not protect against sexually transmitted diseases.
VM your pill at the same time each day to establish a routine and ensure maximum contraceptive protection.
Call your doctor immediately if you experience severe abdominal pain; severe or sudden headache; pain in the chest, groin, or leg, especially the calf; sudden slurring of speech; changes in vision; weakness, numbness, or pain in the arms or legs; coughing up of blood; loss of coordination; or shortness of breath. These symptoms may require emergency treatment.
Other problems that may require medical attention are bulging eyes; changes in vaginal bleeding; fainting; frequent or painful urination; a gradual increase in blood pressure; breast lumps or secretions; depression; yellowing of the skin or whites of the eyes; rash; redness or irritation; upper abdominal swelling, pain, or tenderness; an unusual or dark-colored mole; thick, white vaginal discharge; or vaginal itching or tenderness.
See your doctor for a check-up every 6-12 months.
Some manufacturers include 7 inert or iron pills in their packaging to be taken on days when the drug is not taken. This makes it easier for women to stay on schedule with their pills. The 7 pills bridge the gap between contraceptive cycles and allow women to take 1 pill every day without stopping.
For single- or 2-phase combinations: If you forget to take a pill for 1 day, take 2 pills the following day. If you miss 2 consecutive days, take 2 pills for the next 2 days. Then return to your schedule of 1 pill a day. If you miss 3 consecutive days, do not take any pills for the next 7 days and use another form of contraception; then start a brand new cycle.
Seasonale: The risk of pregnancy increases with each pink tablet you forget. Use another method of non-hormonal backup contraception any time you miss 2 or more pink tablets until you have taken a pink tablet every day for 7 consecutive days. You are protected against pregnancy if you miss 1 or more white tablets, as long as you begin taking the pink tablets again on the proper day.
Seasonique: The risk of ovulation and pregnancy increases with each forgotten light blue-green pill. If you miss 1 light blue-green pill, take it as soon as you remember and take the next pill at your regular time. This may mean you will take 2 pills on the same day. You don’t need to use a backup birth control method if you forget only 1 pill. If you forget 2 light blue-green pills in a row, take 2 pills on the day you remember and take 2 pills the ReYA day. -Then go back to taking 1 pill a day MMI you finish your pack. If you miss 2 01 MbreYight blue-green pills in a row, you must use non-hormonal backup contraception until you have taken a light blue-green pill daily for 7 days in a row. If you miss 1 or more yellow tablets, you are still protected against pregnancy provided you begin taking light blue-green pills again on the proper day.
For 3-phase combinations: If you forget to take a pill for 1 day, take 2 pills the following day. If you miss 2 consecutive days, take 2 pills for the next 2 days. Then return to your schedule of 1 pill a day. If you forget to take a pill for 3 days in a row, stop taking the drug and use an alternate means of contraception until your period starts. ALWAYS use a backup contraceptive method for the remainder of your cycle if you forget even 1 pill of a 3-phase combination.
If you forget to apply the contraceptive patch on the same day of the week once every 4 weeks, you risk a loss of effectiveness on the days after you should have applied it. If the patch comes off or is partially detached in mid-cycle, you must start a new 3-week cycle at once by removing the old patch and applying a new one.
If the vaginal ring is accidentally expelled during the 3 weeks it is normally retained, rinse it off with water and replace it within 3 hours. Do not use hot water. If the ring is not reusable, insert a new ring and continue with your regular schedule. If you do not replace the ring within 3 hours, its effectiveness may be reduced. If you are in week 3 of the cycle, throw the ring away; you may insert a new one immediately, which will begin a new 3-week cycle and cause you to skip a period. Or, you may wait a week, during which time you will have periodic bleeding, and insert a new ring no later than 7 days after the vaginal ring was expelled. This option should be chosen if you had used the ring for 7 days in a row before it was expelled.
If, when it is expelled, you are in week 1 or 2 of your cycle and the ring is out for more than 3 hours, reinsert it and use an additional form of contraceptive until the ring has been worn for 7 consecutive days. A vaginal ring may break and then slip out or cause discomfort. Throw the ring away if this happens.
Missing a pill reduces your protection. If you keep forgetting to take your pills, you must use another birth control method.
If you take drugs that reduce the effectiveness of contraceptive drugs (see “Drug Interactions”), use a backup contraceptive method during that cycle to PMNeiA accidental pregnancy.
GOOD tlL:Inlal hygiene is essential while taking contraceptive drugs. See your dentist regularly and brush and floss carefully because contraceptive drugs may increase the risk of an oral infection.
Contraceptive drugs may increase your sensitivity to the sun.
Wearing contact lenses may be uncomfortable while taking contraceptive drugs because the pills can cause minor changes in the shape of your eyes.
All contraceptive prescriptions come with a “patient package insert.” Read it thoroughly as it gives detailed information about the drug and is required by federal law.

cytotoxic drugs A term applied to drugs that can kill cancer cells. In practice, many factors influence their therapeutic value. They are rarely selective, and therapeutic doses usually have a toxic effect on sonic normal cells. They may attack cancer cells at different stages of development, as actively dividing cells are more susceptible than resting cells. They may not reach the cancer cells in adequate concentration, or resistance to the drug may develop. The dose may also depend to some extent on the patient’s tolerance of the drug, and combined treatment with two or more drugs may have the advantages of increased potency with reduced toxicity. All cytotoxic drugs, with the exception of bleomycin and vincristine, bring about a depression of the bone marrow, which may be severe, and some degree of hair loss, which is usually reversible. Severe nausea and vomiting are also common, and early use of powerful antiemetics is essential. Many cytotoxic agents are tissue irritants, and with i.v. treatment great care must be taken to avoid extravasation, as severe local tissue damage can occur.

danthron A synthetic anthraquinone laxative used mainly for constipation in the aged, and in drug-induced constipation in the terminally ill. Not suitable for routine use by other patients.
Dose: given in doses of 25–25 mg as codanthramer, and acts within 6-12 hours. the urine may be coloured red.
dantrolene A skeletal muscle relaxant that acts on the muscle fibre, and not at the myoneural junction. The action may be linked with an interference with the movement of calcium ions. It is used in the severe and chronic spastic states that occur after stroke, spinal cord injury, and in multiple sclerosis.
Dose: 21 ing daily initially, increased at weekly intervals up to a maximum of 400 mg daily, as the response is slow and May be inadequate. The side-effects of weakness and Gangue are mild, and often transient, but liver function tests during treatment are essential. Dantrolene is also of value in malignant hyperthermia, a rare but serious complication of anaesthesia, and is given in doses of I mg/kg by i.v. injection as soon as the condition is diagnosed,

dapsone A sulphone compound used in the ti,atnient of leprosy.
Dose: 25-400 mg orally twice weekly and continued for some years. Resistance to dapsone may occur, and combined treatment with clofazimitic and rifarnpicin may lie necessary. Dapsone is sometimes given with pyrimetharnine in chlotoquine-resistaut malaria. Side-effects are nausea, rash, neuropathy and myelodepression.
duration of action. Used in the diagnosis and control of diabetes insipidus, and in the treatment of nocturnal eneuresis. Dose: 10-20pg intranasally once or twice
a day; 1-4 pg daily by injection. IMAM.
desoxymethasone A corticosteroid, for local application in acute inflammatory and allergic skin conditions. Used as oily cream 0.25%. (Stiedex).
daunorubicin See doxorubicin.
debrisoquine An adrenergic neurone blocking agent with the actions, uses and side-effects of guanethidine, except that it is less likely to cause diarrhoea. It is used mainly in resistant hypertension, in association with other drugs. (Declinax).
See page 148 and Table 21.
deflazacort A glucocorticoid with the actions and uses of related drugs, and comparable in activity with prednisolone. Dose: initially in acute conditions up to 120 mg daily; maintenance dose 3-18 mg daily. (Calcort). See hydrocortisone, page 55 and Table 36.
demeclocycline An antibiotic with the actions, uses and side-effects of tetracycline, but more likely to cause photo-allergic reactions.
Dose: 600 mg daily. Used occasionally in hyponatraemia due to overactivity of the antidiuretic hormone. (Ledermycin).
desferrioxamine A chelating agent that combines with iron salts to form a soluble non-toxic complex. Of great value in acute ferrous sulphate poisoning in children. Dose: 2 g immediately by i.m. injection, together with gastric lavage (2 g of desferrioxamine/1) followed by a single oral dose of 10 g. It may also be given by continuous i.v. infusion, 15 mg/kg hourly up to a maximum of 80 mg/kg. It may cause hypotension if the infusion is given too rapidly. It is also useful in the treatment of iron-overload caused by repeated blood transfusions, and for aluminium overload in patients On dialysis. (Desferal).
desflurane An inhalation anaesthetic
similar to CuflUrane. (Suprane).
desmopressin A derivative of vasopressin, with increased potency and longer
dexamethasone A potent synthetic corticosteroid, with reduced salt-retaining properties. Useful in all conditions requiring systemic corticosteroid therapy (except Addison’s disease), including inflammatory and allergic disorders, shock, cerebral oedema and adrenal hyperplasia.
Dose: 0.5-2 mg daily up to a MaXiMUM Of’ 15 mg daily; in shock, 5-20 mg by slow i.v. injection or infusion; in cerebral oedema, 10 ing initially by i.v. injection, followed by 4 mg i.m. 6-hourly. Dexamethasone is also given by infra-articular injection for local inflammation of joints in doses of
0.4-4 mg. It is also used as eye drops (0.1%)
in uveitis, but care is necessary with prolonged treatment as with some patients a ’steroid glaucoma’ may be precipitated. (Decadron). See page M and Table 36.
dexamphetamine sulphate A central nervous system stimulant. It is used in the treatment of narcolepsy and, paradoxically, it is sometimes useful in hyperkinesia in children.
Dose: in narcolepsy, 20-60 mg daily; in hyperkinesia 2.5 mg initially, slowly increased up to a maximunl’of 20 mg daily. Side-effects are insomnia, anorexia and agitation. Dependence and tolerance may occur early. (Dexedrine).
dextran A blood-plasma substitute
obtained from sucrose solutions by bacterial action, and used as solutions of varying molecular weight (dextran 40, 70). Dextran 70 is used as a blood volume expander by i.v. injection in some cases of shock; dextran 40 is used mainly to improve postoperative peripheral circulation, reduce blood viscosity, and to prevent thrombo-embolism. Care must be taken to adjust dose to avoid overloading the circulation. Any blood-matching should be carried out before giving dextran. (Gentran; Macrodex; Rheomacroclex).
