Naratriptan (trade names include Amerge) is a triptan drug marketed by GlaxoSmithKline and is used for the treatment of migraine headaches.

[7] Side effects include: sensations of warmth/heat, dizziness, drowsiness, tingling of the hands or feet, nausea, dry mouth and unsteadiness, chest pain/pressure, throat pain/pressure, unusually fast/slow/irregular pulse, and mental/mood changes.

[6] The causes of migraine are not clearly understood; however, the efficacy of naratriptans and other triptans is believed to be due to their activity as 5-HT (serotonin) agonists.

[8][9] In July 2010, in the wake of the patent expiration, several drug manufacturers, including Roxane Labs,[10] Sandoz[11] and Teva Pharmaceuticals,[12] announced that they were launching generic Naratriptan medications.

[13] On December 23, 2014, in response to a request from Health Canada, importers in Canada agreed to quarantine the importation of health products, including generic Naratriptan manufactured for both Sandoz and Teva, from Dr. Reddy's Laboratories in Srikakulam, India.
