Celecoxib (sel-eh-KOX-ib)
Brand Name
Celebrex
Type of Drug
Cyclooxygenase-2 (COX-2) inhibitor nonsteroidal anti-inflammatory
drug (NSAID).
Prescribed For
Osteoarthritis, rheumatoid arthritis, juvenile rheumatoid arthritis, acute pain, some colon polyps (FAR), menstrual pain, and arthritis of the spine (ankylosing spondylitis).
General Information
Traditional NSAIDs work primarily by blocking the effects of COX-2, a body enzyme that plays an important role in regulating pain and inflammation. But these NSAIDs also have an unwanted effect: They interfere with cyclooxygenase-1 (COX-1), a related enzyme that helps to maintain the stomach’s protective lining. NSAIDs that block the effects of this enzyme may produce side effects such as stomach irritation, gas, and stomach ulcers.
COX-2 inhibitors such as celecoxib are a class of NSAIDs that work about as well as the older NSAIDs. In fact, both 200 mg a day and 400 mg a day of celecoxib work as well as naproxen 500 mg twice a day. They interfere primarily with COX-2, leaving the stomach-protecting COX-1 relatively unaffected. This means that COX-2 inhibitor NSAIDs can relieve pain and inflammation just like traditional NSAIDs but are less likely to cause gastrointestinal (GI) side effects. Another advantage of celecoxib is that it does not cause thinning of the blood or affect blood platelets as can happen with older NSAIDs. Celecoxib is broken down in the liver.
Black patients absorb about 40% more celecoxib than Caucasians; its importance is unclear. Celecoxib is the first drug proven effective in reducing the number of intestinal polyps in people with the rare genetic disorder FAR
Cautions and Warnings
Do not take celecoxib if you are allergic or sensitive to any of its ingredients or to sulfa drugs. NSAIDs should not be taken by people with asthma or by those who have had a” allergic reaction to aspirin or another NSA13.1hey can develop a group of sympWMS V1Jnny nose with or without nasal polyps and a severe bronchial spasm) known as the aspirin triad.
COX-2 inhibitors, including celecoxib, have been associated with high blood pressure, kidney damage, heart attacks, and stroke. It should not be used to treat pain associated with heart bypass surgery. Two other COX-2 inhibitors were taken off the market because of safety concerns. Rofecoxib was removed because safety issues were noted after people had taken it for 18 months or more. Valdecoxib was taken off the market because of the lack of safety data, severe skin rashes, and concerns raised in people taking the drug after having had heart surgery.
NSAIDs can cause GI bleeding and ulcers and stomach perforation. This can occur at any time, with or without warning, in people who take NSAIDs regularly. Celecoxib should be used with caution by people who have had stomach ulcers or GI bleeding. Minor upper GI problems, such as upset stomach, are common and may occur at any time during NSAID therapy. People who develop bleeding or ulcers and continue NSAID treatment should be aware of the risk of developing more serious side effects. Risk of GI bleeding and ulcers is increased with longer duration of therapy as well as treatment with oral corticosteroids and anticoagulants, smoking, alcoholism, older age, and general poor health.
Children taking celecoxib may be more likely to vomit blood, suffer acute kidney failure, or develop rashes.
Celecoxib has not been studied in people with severe kidney disease. They should not use this drug unless their doctors closely monitor their kidney function.
Celecoxib can cause liver irritation and should be used with caution by people with hepatitis or cirrhosis. People with moderate liver disease can have twice as much celecoxib in their blood and require a reduced dosage. The effect of celecoxib in people with severe liver failure is not known.
Possible Side Effects
Side effects are similar to those of traditional NSAIDs. Stomach and intestinal side effects are about half as common.
♦    Most common: headache.
✓    Common: diarrhea, upset stomach, sinus irritation, and respiratory infection.
♦    Less common: abdominal pain, gas, nausea, back pain, swelling in the legs m arms, accidental injuries, sleeplessness, dizziness, sore throat, runny nose, and rash.
✓    Rare: Rare side effects can occur in almost any part of the body. Contact your doctor if you experience any side effect not listed above.
Drug Interactions
•    Alcohol may increase the risk of serious GI-related side ef-
fects. Avoid alcohol.
•    Combining celecoxib with an aluminum and magnesium antacid slightly reduces the amount of drug absorbed. Separate doses of these antacids and celecoxib by 1-2 hours.
•    Fluconazole and lithium may raise celecoxib blood levels and increase the risk of side effects.
•    While celecoxib may be combined with low dosages of as-
pirin, taking these drugs together can increase the risk of
stomach or intestinal ulcers or other complications. The ulcer
risk associated with this combination is less than that posed
by single-drug therapy with a traditional NSAID.
•    Celecoxib can reduce the blood-pressure-lowering effect of angiotensin-converting enzyme (ACE) inhibitors and diuretic drugs. This combination can also increase the risk of kidney damage after chronic celecoxib use.
•    Celecoxib may affect lithium blood levels.
•    NSAIDS can reduce the effect of furosemide and thiazidetype diuretics.
•    Celecoxib should be used cautiously with warfarin. Concurrent use of these drugs may cause an increased risk of bleeding complications.
Food Interactions
Celecoxib can be taken without regard to Food or meals. For optimal effectiveness, avoid taking this drug with high-fat meals.
Usual Dose
Adult (age 18 and over): arthritis-100-200 mg once or twice a day. FAP-400 mg twice a day.
Child (age 2 and over): juvenile rheumatoid arthritis-22-55 lbs: 50 mg twice a day; over 55 lbs: 100 mg twice a day.
Child (under age 2): not recommended.
Overdosage
Overdosage symptoms include Mnargy, drowsiness, nausea, vomitiR(;, 16M Stomach pain. Stomach or intestinal bleeding or severe allergic reactions can occur. High blood pressure, kidney failure, breathing difficulties, and coma are rare.
The victim should be taken to a hospital emergency room. ALWAYS bring the prescription bottle or container.
Special Information
Call your doctor if you develop rash, itching, unexplained weight gain, nausea, fatigue, jaundice (yellowing of the skin or whites of the eyes), flu-like symptoms, lethargy, swelling, black stools, severe stomach pain, persistent headache, or any bothersome or persistent side effect.

Special Populations
Pregnancy/Breast-feeding: celecoxib has caused birth defects in animal studies. Any NSAID may affect fetal heart development during the second half of pregnancy. Pregnant women should not take celecoxib without their doctor’s approval. When this drug is considered crucial by your doctor, its potential benefits must be carefully weighed against its risks.
NSAIDs may pass into breast milk. There is a possibility that a nursing mother taking celecoxib could affect her baby’s heart or cardiovascular system. Nursing mothers who must take this drug should use infant formula.
Seniors: Generally, seniors can take this drug without special precaution. Those who weigh less than 110 lbs. should begin with the lowest possible dosage.

Generic Name
Calcitonin (kal-sih-TOE-nin)
General Information
Calcitonin helps to strengthen bone by adding more calcium to it and slowing the natural process by which bone is broken down. The calcitonin used in this drug is essentially identical to human calcitonin except that it is more potent. It is a synthetic version of the natural calcitonin found in salmon. Calcitonin can increase bone density and reduce the risk of fractures of the vertebrae (bones that comprise the spinal column), which are associated with back pain and loss of height. Calcitonin has been available for years as an injection, but the development of the nasal spray makes the drug easier to use.
Cautions and Warnings
Do not use calcitonin if you are allergic or sensitive to any of its ingredients. Although serious allergic reactions were reported with the injectable form, none have occurred with the nasal spray.
Changes in the tissues lining your nose are possible with longerm use of this product. An initial nasal examination and then peiodic examinations are recommended.
Possible Side Effects
V Most common: stuffy nose, runny nose, and other nasal symptoms; and back pain.
V Less common: joint pain, nosebleed, and headache.
Drug Interactions
None known.
Food Interactions
None known. Usual Dose
Adult: I spray (200 IU) a day. Child: not recommended.
Little is known about the effects of calcitonin overdose or accidental ingestion. Nausea and vomiting have been reported after high doses. Call your local poison control center for more information. Overdose victims should be taken to a hospital emergency room. ALWAYS bring the prescription bottle or container.
Special Information
Alternate nostrils daily when using the nasal spray.
Before you take your first dose, you must activate the pump. Hold the bottle upright and press the two white arms toward the bottle 6 times until a faint spray is emitted. Once this occurs, the pump is activated and ready for use. It is not necessary to reactivate the pump every day.
Store new, unassembled bottles in the refrigerator. Keep the bottle in use at room temperature and discard after 30 days.
If you forget to administer a dose of the nasal spray, do so as soon as you remember. If it is almost time for the next dose, skip the dose you forgot and continue with your regular schedule. Call your doctor if you forget 2 or more doses.
Call your doctor if you develop severe nose irritation or any unusual or intolerable symptom. Follow your doctor’s recommendations regarding calcium and vitamin D supplements. This drug is not intended to replace the need for dietary calcium.
Special Populations
Pregnancy/Breast-feeding: calcitonin does not cross into the fetal circulation, though animal studies have associated the injectable form of the drug with low birth weight. This drug is recommended for use during pregnancy only if its possible benefits outweigh its risks.
It is not known if calcitonin passes into breast milk, though animal studies have shown that it reduces the amount of milk produced. Nursing mothers who must use calcitonin should consider using infant formula.
Seniors: Seniors may use this product without special precaution.

Generic Name
Bupropion (bue-PROE-pee-on) M
Brand Names
Budeprion    Wellbutrin SR
Budeprion XL    Wellbutrin XL
Wellbutrin    Zyban
Type of Drug
Antidepressant and smoking deterrent.
Prescribed For
Depression, seasonal affective disorder, and nicotine addiction.
General Information
Bupropion is used for major depression and seasonal affective disorder, and may work as a smoking deterrent by acting on key hormone systems in the brain. It works primarily on dopamine and noradrenaline, unlike the SSRI antidepressants, which primarily work on serotonin. Bupropion may not act until you have taken it for 2-4 weeks. The drug clears your system about 2 weeks after you stop taking it.
Cautions and Warnings
Do not take bupropion if you are allergic or sensitive to any of its ingredients.
Antidepressants have been associated with an increased risk of suicide, especially in children and teenagers. Suicide is always a risk in depressed people, who should only be allowed to have minimal quantities of medication in their possession. Clinical worsening of a depressed person’s condition may also occur early
therapy with anticlepressa”kS.
People with seizure disorders, people who have had a seizure in the past, and people with bulimia or anorexia nervosa should be very careful about taking bupropion because they are at a higher risk of having a seizure. About 4 in 1000 people taking bupropion in dosages up to 450 mg a day develop a seizure. The risk of developing a seizure increases by about 10 times with dosages between 450 and 600 mg a day. About half of the people who developed a seizure on bupropion had a risk factor such as a history of head injury, a previous seizure, or a nervous system tumor, or were taking another drug associated with increased seizure risk.
People with unstable heart disease or those who have had a recent heart attack should take this drug with caution because of possible side effects.
Many people taking bupropion experience some restlessness, agitation, anxiety, and sleeplessness, especially soon after they start taking the drug. Some even require sleeping pills to counter this effect, and others find the stimulation so severe that they have to stop taking bupropion.
Bupropion may trigger a manic episode in those with depression or bipolar disorder.
People taking bupropion may experience hallucinations, delusions, or psychotic episodes. Dosage reduction or drug withdrawal is usually necessary to manage these reactions.
One-quarter of those who take bupropion lose their appetite and 5 or more lbs. of body weight. People who have lost weight due to their depression should be cautious about taking bupropion.
People switching from bupropion to a monoamine oxidase inhibitor (MA01) antidepressant, or vice versa, should allow at least 2 weeks to pass between stopping one drug and starting the other.
People with kidney or liver disease require less bupropion at the beginning of treatment. Dosage should be increased cautiously.
An antidepressant other than bupropion should be seriously considered for people with a history of drug abuse because of the mild stimulation bupropion causes. These people may require larger-than-usual dosages, but they are still susceptible to seizures at these higher dosages.
Possible Side Effects
About 10% of people stop taking bupropion due to side effects.
♦ Most common: dry mouth; dizziness; rapid heartbeat; headache, including migraine; excessive sweating; nausea; vomiting; constipation; appetite loss; weight changes: sedation; agitation; sleeplessness; and tremors.
Possible Side Effects (continued)
V Less common’. upset stomach, diarrhea, increased appetite, menstrual complaints, impotence, urinary difficulties, slowness of movement, salivation, muscle spasms, warmth, uncontrolled muscle movement, compulsion to move around or change positions, abnormal heart rhythms, blood-pressure changes, heart palpitations, fainting, itching, redness and rash, confusion, hostility, loss of concentration, reduced sex drive, anxiety, delusions, euphoria (feeling “high”), fatigue, joint pain, fever or chills, respiratory infection, and visual, taste, and hearing disturbances.
Drug Interactions
•    Phenelzine (an MAGI) increases the risk of bupropion side effects. Allow at least 2 weeks to pass between stopping an MAGI and starting bupropion. Serious side effects can occur.
•    Carbamazepine may reduce blood concentrations of bupropion.
•    People taking both bupropion and levodopa + carbidopa or amantadine experience increased side effects. People taking these drugs should have their bupropion dosage increased gradually.
•    Ritonavir may significantly increase bupropion blood levels and the risk of side effects.
•    Don’t mix bupropion with other drugs that increase the risk of seizures—including tricyclic antidepressants, haloperidol, lithium, loxapine, molindone, phenothiazine sedatives, and thioxanthene sedatives.
•    Combining bupropion with a nicotine replacement drug can cause high blood pressure.
•    Combining bupropion with warfarin can increase the risk of side effects.
•    Do not comtImP. INO~bujfin and Zyban, as they contain the same active ingredient.
•    Alcohol should be avoided by people taking bupropion.
Food Interactions
Bupropion may be taken with food if it upsets your stomach.
Usual Dose
Depression
Adult: 200-450 mg a day; normal daily dosage is 300 mg. Child (under age 18): not recommended.
Smoking Cessation
Adult: 150 mg twice a day. Begin treatment while you are still
smoking.
Child (under age 18): not recommended.
Overdosage
Symptoms of overdose are likely to include severe side effects, such as seizures—present in a third of overdoses—hallucinations, loss of consciousness, and abnormal heart rhythms. Overdose victims should be taken to a hospital emergency room at once. ALWAYS bring the prescription bottle or container.
Special Information
Do not stop taking bupropion without your doctor’s knowledge. Suddenly stopping the drug may cause withdrawal reactions and side effects.
Call your doctor if you experience agitation or excitement, restlessness, confusion, difficulty sleeping, anxiety, panic attacks, sleeplessness, irritability, hostility, aggressiveness, acting impulsively, a manic reaction, deepening depression, suicidal thinking, fast or abnormal heart rhythm, severe headache, seizure, rash, fainting, or any unusual or persistent side effect.
Bupropion may make you tired, dizzy, or lightheaded. Be careful when driving or doing any task that requires concentration.
Alcohol, sedatives, and other nervous system depressants increase the depressant effects of this drug. Alcohol also increases the risk of a seizure.
If you forget a dose, take it as soon as you remember. If it is almost time for your next dose and you take it several times a day, take 1 dose as soon as you remember and another in 3 or 4 hours, then go back to your regular schedule. Do not take a double dose.
Special Populations
Pregnancy/Breast-feeding: The safety of using bupropion during pregnancy is not known. When your doctor considers this drug crucial, its potential benefits must be carefully weighed against its risks. Pregnant women trying to quit smoking should use non-drug methods until their pregnancy is completed.
Bupropion passes into breast milk. Nursing mothers who must use bupropion should use infant formula.
Seniors: Seniors with reduced kidney or liver function may require reduced dosage.
