Wellbutrin SR: What It Is, How to Use It, and Safety Tips
Wellbutrin SR (bupropion sustained release) is an antidepressant many people choose for low mood and low energy. It works differently than SSRIs — it boosts certain brain chemicals linked to motivation and focus. People notice it often won’t cause the same sexual side effects or weight gain that other antidepressants do.
How to take Wellbutrin SR
The SR version is timed-release and usually taken twice a day. A common start is 150 mg once daily for a few days, then 150 mg twice daily. Doctors usually keep the total at or below 400 mg per day because higher doses raise the risk of seizures. Take doses 8 hours apart to reduce sleep problems. You can take it with or without food, but keep a consistent schedule so your body adjusts.
If you miss a dose, take it as soon as you remember unless the next dose is close. Don’t double up to catch up. If you stop the drug, talk with your prescriber about a safe taper plan — stopping suddenly isn’t ideal for some people.
Safety warnings & interactions
Be careful if you have a history of seizures, a brain injury, or an eating disorder like bulimia — these raise seizure risk with bupropion. Also avoid using Wellbutrin SR within 14 days of MAOI antidepressants. Mixing bupropion with other drugs that lower the seizure threshold (for example, high-dose antipsychotics, some pain meds like tramadol) needs medical review.
Avoid heavy drinking while starting or stopping this medicine — sudden alcohol withdrawal increases seizure risk. Watch for side effects such as insomnia, dry mouth, sweating, tremor, headache, and sometimes anxiety. If you feel faint, confused, or have seizures, get medical help right away.
Many people experience clearer energy and less appetite while on Wellbutrin SR. It can also help people trying to quit smoking (bupropion marketed as Zyban for cessation). Still, it doesn’t work for everyone — effects show up over weeks, and your dose may need adjustments.

Bottom line: Wellbutrin SR can be a great option if you want an antidepressant that often avoids sexual side effects and weight gain, but it does carry seizure risk in certain situations. Keep regular follow-ups, follow dosing advice, and report new symptoms quickly so your prescriber can keep you safe and get the best results.
