What is Wellbutrin® and what does it treat?

Bupropion is an antidepressant medication that works in the brain.  It is approved for the treatment of major depressive disorder (MDD), seasonal affective disorder (SAD), and to help people stop smoking.  

Symptoms of depression include:

SAD is a type of depression that occurs at the same time every year.  It usually starts in the fall and may continue through the winter.

What is the most important information I should know about Wellbutrin®?

Do not stop taking bupropion even when you feel better.  Only your healthcare provider can determine the length of treatment that is right for you.

Missing doses of bupropion may increase your risk for relapse in your symptoms.

Stopping bupropion abruptly may result in one or more of the following withdrawal symptoms: irritability, nausea, feeling dizzy, vomiting, nightmares, headache, and/or paresthesias (prickling, tingling sensation on the skin).

Depression is also a part of bipolar illness.  People with bipolar disorder who take antidepressants may be at risk for "switching" from depression into mania.  Symptoms of mania include "high" or irritable mood, very high self esteem, decreased need for sleep, pressure to keep talking, racing thoughts, being easily distracted, frequently involved in activities with a large risk for bad consequences (for example, excessive buying sprees).

Are there specific concerns about Wellbutrin® and pregnancy?

If you are planning on becoming pregnant, notify your healthcare provider to best manage your medications.  People living with MDD who wish to become pregnant face important decisions.  Untreated MDD has risks to the fetus, as well as the mother.  It is important to discuss the risks and benefits of treatment with your doctor and caregivers.

Caution is advised with breastfeeding since bupropion does pass into breast milk.

What should I discuss with my healthcare provider before taking Wellbutrin®?

How should I take Wellbutrin®?

Bupropion is usually taken 1, 2, or 3 times per day with or without food.  The number of times each day you take the medication will depend on which product your healthcare provider has prescribed.  If you have been instructed to take it more than once daily, it is usually taken with 4-6 hours between doses.  

You should not take more than one bupropion product at the same time.

Typically patients begin at a low dose of medicine and the dose is increased slowly over several weeks.  

The dose usually ranges from 150 mg to 450 mg.  Only your healthcare provider can determine the correct dose for you.

The sustained release and extended release forms should be swallowed whole.  They should not be chewed, crushed, or broken.

Consider using a calendar, pillbox, alarm clock, or cell to help you remember to take your medication.  You may also ask a family member or friend to remind you or check in with you to be sure you are taking your medication.

¬†What happens if I miss a dose of Wellbutrin®?

If you miss a dose of bupropion, take it as soon as you remember if it is still early in the day.  Do not take a missed dose after 5:00 PM, as this may interfere with sleep.  Do not take a missed dose of extended-release forms after 2:00 PM, as this may interfere with sleep.  Discuss missed doses with your healthcare provider.  Do not double your next dose or take more than what is prescribed
