What should I watch for while taking bupropion?

Visit your prescriber or health care professional for regular checks on your progress. You may have to take bupropion for several days before you see the effects. If you have been taking bupropion for some time, do not suddenly stop taking it. Your prescriber or health care professional may want you to gradually reduce the dose; ask for advice.

Patients and their families should watch out for worsening depression or thoughts of suicide. Also watch out for sudden or severe changes in feelings such as feeling anxious, agitated, panicky, irritable, hostile, aggressive, impulsive, severely restless, overly excited and hyperactive, or not being able to sleep. If this happens, especially at the beginning of bupropion treatment or after a change in dose, call your doctor.

You may get dizzy or have blurred vision. Do not drive, use machinery, or do anything that needs mental alertness until you know how bupropion affects you. Do not stand or sit up quickly, especially if you are an older patient. This reduces the risk of dizzy or fainting spells.

Alcohol may increase dizziness or drowsiness; avoid alcoholic drinks while taking bupropion. Drinking excessive alcoholic beverages, using sleeping or anxiety medicines, or quickly stopping the use of these agents while taking bupropion may increase your risk for a seizure (convulsion).

Bupropion can make your mouth dry. Chewing sugarless gum, sucking hard candy and drinking plenty of water will help.

Do not treat yourself for coughs, colds, or allergies without asking your prescriber or health care professional for advice. Also do not take any herbal or non-prescription medicines for weight loss without your prescribers advice. Some ingredients may increase possible side effects.

If you are going to have surgery, tell your prescriber or health care professional well before your scheduled surgery that you are taking bupropion.
