What is/are Naratriptan?
Naratriptan (trade names include Amerge and Naramig) is a triptan drug marketed by GlaxoSmithKline and is used for the treatment of migraine headaches. Naratriptan is available in 2.5 mg tablets. It is a selective 5-HT1 receptor subtype agonist.
Side effects include: dizziness, drowsiness, tingling of the hands or feet, nausea, dry mouth and unsteadiness. If these effects persist or worsen, notify your doctor promptly. Side-effects which are unlikely and which should be promptly reported include: chest pain/pressure, throat pain/pressure, unusually fast/slow/irregular pulse, one-sided muscle weakness, vision problems, cold/bluish hands or feet, stomach pain, bloody diarrhea, mental/mood changes, and fainting. In the unlikely event you have a serious allergic reaction to this drug, seek immediate medical attention. Symptoms of a serious allergic reaction include: rash, itching, swelling, severe dizziness, trouble breathing (swelling of the throat).
The use of naratriptan with MAOIs and serotonergic drugs may result in the life threatening serotonin syndrome. Make sure your doctor/pharmacist is aware of all your current medications (including as needed medications) before taking this drug.
Mechanism of action
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 5HT (serotonin) agonists.
