Key takeaways
- Wellbutrin (bupropion) is an antidepressant approved by the Food and Drug Administration (FDA) for major depressive disorder (MDD) and seasonal affective disorder (SAD). It works by preventing the reabsorption of norepinephrine and dopamine, brain messengers involved in mood regulation.
- You can take Wellbutrin at any time of day if you take it once daily, but taking it in the morning may help minimize sleep problems like insomnia, a reported side effect. If you take it twice daily, space doses at least 8 hours apart.
- You may start feeling the effects of Wellbutrin within 1 to 2 weeks, but it could take 6 to 8 weeks of consistent use to experience the full benefits. If you miss a dose, take your next dose at the usual time — don’t double up.
Overview
Wellbutrin (bupropion) is a medication approved by the Food and Drug Administration (FDA) for treating major depressive disorder (MDD), commonly known as depression. Depending on the version of Wellbutrin you take, it may also help treat seasonal affective disorder (SAD).
Wellbutrin comes in two versions, both of which release the drug slowly into your body over time:
- Wellbutrin SR, a sustained-release tablet
- Wellbutrin XL, an extended-release tablet
You typically take Wellbutrin once or twice daily, depending on the form your doctor has prescribed. The specific time of the day and frequency may vary according to your needs.

When to take Wellbutrin

The best time to take Wellbutrin may vary depending on medical recommendations and the specific form of Wellbutrin your doctor prescribes.
If you take Wellbutrin once per day, you can take it at any time of the day. However, some people may find it helpful to take Wellbutrin in the morning to minimize difficulties with sleep. Sleep problems, such as insomnia, are a reported side effect of Wellbutrin.
If you take Wellbutrin twice per day, you’ll take your second dose at least 8 hours after your first dose. For bupropion immediate-release tablets, you may take three doses per day with at least 6 hours between each dose.
You can take Wellbutrin with or without food, but taking it with food may help reduce the likelihood of nausea.
The dosage of Wellbutrin and its generic varies depending on your symptoms and the form you take. The starting dosage may range from 150 milligrams (mg) to 200 mg per day. Eventually, your doctor will likely increase your dosage to 300 mg or more per day.
What to do if you miss a dose
Don’t worry if you miss a dose of Wellbutrin. Just take Wellbutrin at the time you would usually take your next dose.
Do not take two Wellbutrin doses to make up for the missed dose. It’s important to be consistent in your medication schedule. Taking your doses at the same time(s) each day helps ensure the drug is as effective as possible.
Does Wellbutrin make you sleepy?
Wellbutrin is a stimulant and is less likely to make you sleepy than other similar drugs. If you take it too close to bedtime, it may keep you alert and awake at night.
Wellbutrin may lead to other side effects, including:
- headaches
- dry mouth
- nausea or vomiting
- increased sweating
- increased heart rate or palpitations
- changes in appetite or weight
Not everyone experiences these side effects, and their severity can differ from person to person.

Note: Wellbutrin and its generic version, bupropion, have a boxed warning for the risk of suicidal thoughts and behaviors in certain people. A boxed warning is the most serious warning from the Food and Drug Administration (FDA). For more information, see this article or talk with your doctor.
