Interactions with Dietary Supplements
5-Hydroxytryptophan
(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.
Interactions with Foods and Other Compounds
Food
Tramadol may be taken with or without food.3
Alcohol
Tramadol may impair mental ability and physical coordination.4 Alcohol may
intensify these effects and increase the risk of accidental injury. People taking tramadol are
cautioned to avoid alcohol.
