(5-HTP) and L-tryptophan
Tramadol, which blocks serotonin reuptake in the brain, has been associated with two cases of
serotonin syndrome.1 2 5-HTP and L-tryptophan are converted to serotonin
in the brain. While no interactions have yet been reported with tramadol and 5-HTP or
L-tryptophan, taking 5-HTP or L-tryptophan with tramadol may increase the risk of
tramadol-induced side effects, including serotonin syndrome.
