Below you’ll find answers to a few commonly asked questions about bupropion.

Can bupropion be used for weight loss?

Bupropion is not approved by the Food and Drug Administration (FDA) for weight loss. However, doctors may still prescribe the drug off-label for this purpose. Off-label use is when a drug that’s FDA-approved for certain conditions is prescribed for a different use.

Talk with your doctor if you’d like to learn more about off-label uses for bupropion, including weight management.

Is bupropion similar to Adderall? Can it be used for ADHD?

No, bupropion is not similar to Adderall. For example, Adderall is a controlled substance. This means there are certain regulations for prescribing and dispensing Adderall in the United States. Bupropion is not a controlled substance.

Bupropion isn’t approved by the FDA for treating attention deficit hyperactivity disorder (ADHD). But doctors may still prescribe the drug off-label for this purpose.

Your doctor can provide more information about off-label uses for bupropion, including ADHD.

How does bupropion compare to similar drugs, such as buspirone and sertraline?

If you’re prescribed bupropion, you may wonder how it compares to similar drugs.

Bupropion and sertraline (Zoloft) are both FDA-approved to treat major depressive disorder (depression). But sertraline is also approved to treat other conditions. In addition, both are different types of antidepressants: Sertraline is a selective serotonin reuptake inhibitor, while bupropion is a norepinephrine and dopamine reuptake inhibitor.

Buspirone is prescribed to treat anxiety disorders, such as generalized anxiety disorder. Unlike bupropion, buspirone isn’t prescribed to treat depression. But it may be used to treat anxiety related to depression.

Talk with your doctor or pharmacist if you’d like to learn more about how bupropion compares to similar drugs.

What is bupropion’s half-life? How does the drug work?

Bupropion has a half-life of about 21 hours. A drug’s half-life explains how long it takes your body to get rid of half of a dose of the drug after you take it.

It’s not fully understood how bupropion works to treat depression. It’s thought that the drug’s effect on certain chemicals in your brain may help to ease symptoms of this condition.

It can take several weeks for bupropion to work to treat symptoms of depression. If you have questions about when your symptoms may decrease while taking bupropion, talk with your doctor or pharmacist.

If I stop taking bupropion, is withdrawal possible?

No, withdrawal symptoms aren’t expected with bupropion, according to studies of the drug.

Withdrawal symptoms are side effects that can occur when you suddenly stop taking a drug that your body has become dependent on. (When you’re dependent on a drug, your body needs the drug to function as usual.) But withdrawal symptoms aren’t likely to occur when stopping bupropion suddenly.

If you’d like to stop taking bupropion, talk with your doctor. Stopping bupropion treatment could cause symptoms of the condition bupropion is treating to return. Your doctor can review other possible treatments for your condition if you’d like to end treatment with bupropion. 

Can bupropion be taken with naltrexone?

Yes, bupropion can be taken with naltrexone.

In fact, the brand-name drug Contrave contains bupropion and naltrexone. Contrave is prescribed to certain adults for help with weight management. For this purpose, Contrave is taken in combination with a balanced diet and exercise.

If you’re interested in learning more about Contrave or medications that may be taken with bupropion, talk with your doctor.
