Oxitriptan, also known as L-5-hydroxytryptophan (5-HTP) and sold under various brand names, is a medication and over-the-counter dietary supplement used in the treatment of depression and for other indications.[2][1][3][4] It is taken by mouth.[1]

Side effects of oxitriptan include appetite loss, nausea, diarrhea, vomiting, and serotonin syndrome.[1][2][3] The drug is a centrally permeable monoamine precursor and prodrug of serotonin and hence acts as a serotonin receptor agonist.[2] Chemically, oxitriptan is an amino acid and a tryptamine.[5]

Oxitriptan has been used clinically since at least the 1970s.[1]
