Generic name: Bupropion
Why is this medication prescribed?
Bupropion (Wellbutrin, Wellbutrin SR), an antidepressant (mood elevator), is used to treat depression. Bupropion (Zyban) is used to help people stop smoking.
This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.
How should this medicine be used?
Bupropion comes as a tablet to take by mouth. It is usually taken one to three times a day and may be taken with or without food. Do not crush, chew, or divide Wellbutrin SR or Zyban tablets. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take bupropion exactly as directed.
Continue to take bupropion even if you feel well. Do not stop taking bupropion without talking to your doctor, especially if you have taken large doses for a long time. Your doctor probably will want to decrease your dose gradually. This drug must be taken regularly for a few weeks before its full effect is felt.
Bupropion can be habit forming. Do not take a larger dose, take it more often, or for a longer period than your doctor tells you.
What special precautions should I follow?
Before taking bupropion,
- tell your doctor and pharmacist if you are allergic to bupropion or any other drugs.
- in addition to the drugs listed in the IMPORTANT WARNING section, tell your doctor and pharmacist what other prescription and nonprescription drugs you are taking, or have taken in the last 2 weeks, especially anticoagulants [warfarin (Coumadin)]; antihistamines; antipsychotics; carbamazepine (Tegretol); cimetidine (Tagamet); diet pills; insulin; levodopa (Sinemet, Larodopa); lithium (Eskalith, Lithobid); MAO inhibitors [phenelzine (Nardil), tranylcypromine (Parnate)]; medication for high blood pressure, seizures, asthma, colds, or allergies; methylphenidate (Ritalin); oral antidiabetic medications; other antidepressants; ritonavir (Norvir); sedatives; sleeping pills; theophylline (Theobid, Theo-Dur, others), thyroid medications; tranquilizers; and vitamins. You should not take Wellbutrin or Wellbutrin SR and Zyban together. Also tell your doctor if you drink large amounts of alcohol or are addicted to cocaine, opiates or other drugs so that you can properly taper and end their use. Abrupt withdrawal increases seizure risk.
- in addition to the conditions listed in the IMPORTANT WARNING section, also tell your doctor if you have or have ever had glaucoma, an enlarged prostate, difficulty urinating, an over active thyroid gland, or liver, or kidney or heart disease.
- tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking bupropion, call your doctor immediately.
- if you are having surgery, including dental surgery, tell the doctor or dentist that you are taking bupropion.
- you should know that this drug may make you drowsy. Do not drive a car or operate machinery until you know how this drug affects you.
- remember that alcohol can add to the drowsiness caused by this drug.
What should I do if I forget a dose?
If you take several doses per day, take the missed dose as soon as you remember it and take any remaining doses for that day at evenly spaced intervals. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule.
If you take bupropion once a day at bedtime and do not remember to take it until the next morning, skip the missed dose. Do not take a double dose to make up for a missed one.
