Important: because 5-HTP raises serotonin, do not combine it with antidepressants or other serotonergic medications (such as SSRIs, SNRIs, MAOIs, or triptans) without practitioner guidance — this can lead to serotonin syndrome. It may also cause drowsiness; avoid combining with sedatives or alcohol.
