Discontinue lasmiditan if symptoms occur. Concurrent use of SSRIs, SNRIs, TCAs, MAO inhibitors, trazodone, triptans, cough syrups (dextromethorphan) or herbal products (St. John's Wort, SAMe) increase serotonin and may cause serotonin syndrome.
Advise patient that overuse of acute migraine drugs (use more than 10 days/mo) may lead to exacerbation of headache (migraine-like daily headaches, or as a marked increase in frequency of migraine attacks).
