Summary
S-adenosylmethionine (SAMe) has serotonergic activity and may add to the serotonin-raising effect of amitriptyline. Serotonin syndrome has been reported with this type of combination, though mainly as isolated reports.
What this interaction means in plain words
Amitriptyline and Same can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
Additive serotonergic effects, with SAMe possibly increasing serotonin turnover while amitriptyline inhibits serotonin reuptake.
What to do
Avoid starting SAMe without clinician review and counsel the patient about symptoms of serotonin toxicity such as agitation, tremor, sweating and fever. Stop SAMe if such symptoms develop.
