Can I take 50 and Buproprion together?

Drug interaction guide

Taking 5-HTP and bupropion together can increase the risk of a rare but serious condition called serotonin syndrome. This happens when there is too much of a chemical called serotonin in your brain. Symptoms can include feeling very agitated, confused, sweating, shivering, fast heartbeat, or muscle twitching. There is also a slightly increased risk of seizures when these substances are combined.

Why this happens

Both 5-HTP and bupropion affect chemicals in the brain. 5-HTP is converted directly into serotonin. While bupropion mainly affects dopamine and noradrenaline, it can also have a minor effect on serotonin levels. Combining them can lead to an over-accumulation of serotonin. Additionally, both substances can lower the 'seizure threshold', making a fit or seizure more likely.

You should speak to your doctor or pharmacist before taking 5-HTP if you are already taking bupropion. It is generally recommended to avoid this combination unless specifically supervised by a healthcare professional. If you are already taking both and feel unwell, confused, or have a high fever, seek medical help immediately.
