Drug interaction guide

Taking 5-HTP and sertraline together can lead to a very serious condition called serotonin syndrome. This happens when there is too much of a chemical called serotonin in your brain and body.

Why this happens

Both 5-HTP and sertraline increase the levels of serotonin in the brain. Sertraline (an SSRI antidepressant) stops the brain from reabsorbing serotonin, while 5-HTP is a building block that the body uses to make more serotonin. Using them at the same time creates a 'double hit' effect that can overwhelm the nervous system.

Do not take 5-HTP if you are taking sertraline. If you have already taken both and feel unwell, seek medical help immediately. Always talk to your doctor or pharmacist before starting any herbal supplements or vitamins while on prescription medication.
