Bupropion is an active substance that belongs to a class of medicines known as atypical antidepressants. It is primarily used to help lift mood and to reduce cravings for nicotine. In the UK, bupropion is found in several prescribed products, including Zyban, Bupron SR, Wellbutrin, Contrave and a combination of bupropion with naltrexone.
A number of tablets and extended-release capsules on the market contain bupropion. The most common brand-name products in the UK are:
These medicines may come as tablets, coated tablets or capsules, and the strength of bupropion can differ between products. Some are available only on prescription, while others require a specialist’s approval.

Bupropion works by gently increasing the activity of two brain chemicals - dopamine and norepinephrine - that are involved in mood, motivation and the brain’s reward system. By boosting these chemicals, the drug can help lift low mood, lessen cravings for nicotine and, in combination with naltrexone, aid appetite control. The effect generally begins within a few days, although full benefits may take several weeks to become clear.
Most people who take bupropion notice only mild, short-lasting effects. Typical reports include:

Anyone who has previously experienced an allergic reaction to bupropion should avoid it.
