bupropion prescription: what you need to know

If you or someone you love has been asked to take bupropion, you probably have a lot of questions. Is it safe? How often should you take it? What side effects might show up? This guide breaks down the basics so you can feel confident about your prescription.

Bupropion is sold under brand names like Wellbutrin and Zyban, but the active ingredient is the same. Doctors use it mainly for depression, seasonal affective disorder, and to help people quit smoking. It works by boosting the brain chemicals norepinephrine and dopamine, which can lift mood and reduce cravings.

How bupropion is prescribed

When a doctor writes a bupropion prescription, they’ll pick a dose based on why you need it. For depression, the usual start is 150 mg once daily, usually taken in the morning to avoid insomnia. After a few days, many doctors increase the dose to 300 mg per day, either as a single dose or split into two doses (150 mg each). The max recommended dose is 450 mg daily.

If you’re using bupropion to quit smoking, the starting dose is often 150 mg once daily for three days, then you jump to 150 mg twice daily. The idea is to build up the level in your system gradually, which helps keep side effects low.

Pharmacies will usually give you a 30‑day supply, and you’ll need a follow‑up visit after a week or two. That check‑in lets the doctor see how you’re doing, adjust the dose if needed, and catch any problems early.

Managing side effects and safety

Most people tolerate bupropion well, but a few common side effects can pop up. Expect dry mouth, headache, or a slight increase in heart rate. These usually fade after the first week. If you notice a rash, fever, or persistent trouble sleeping, call your doctor right away.

One serious risk is seizures, especially at higher doses or if you have a history of seizures. That’s why doctors stay below the 450 mg limit and ask about any seizure history before prescribing.

Alcohol can raise the seizure risk, so keep drinking to a minimum while on bupropion. Also, avoid other drugs that lower the seizure threshold, like certain antipsychotics or stimulants, unless your doctor says it’s safe.

When you pick up your prescription, double‑check the label: make sure the name, strength, and directions match what the doctor wrote. If anything looks off, ask the pharmacist before leaving the store.

Storing bupropion is simple—keep it at room temperature, away from moisture and out of reach of children. If you miss a dose, take it as soon as you remember, unless it’s close to your next scheduled dose. In that case, just skip the missed one; don’t double up.

Finally, remember that bupropion isn’t a quick fix. It can take 2‑4 weeks to feel the full benefit for depression, and a few weeks to notice reduced cravings when quitting smoking. Patience and staying in touch with your healthcare provider are key.
