Naratriptan is used to treat the symptoms of migraine headaches (severe, throbbing headaches that sometimes are accompanied by nausea and sensitivity to sound or light). Naratriptan is in a class of medications called selective serotonin receptor agonists. It works by narrowing blood vessels around the brain, stopping pain signals from being sent to the brain, and stopping the release of certain natural substances that cause pain, nausea, and other symptoms of migraine. Naratriptan does not prevent migraine attacks or reduce the number of headaches you have.
Naratriptan comes as a tablet to take by mouth. It is usually taken at the first sign of a migraine headache. If your symptoms improve after you take naratriptan but return after 4 hours or longer, you may take a second tablet. However, if your symptoms do not improve after you take naratriptan, do not take a second tablet before calling your doctor. Your doctor will tell you the maximum number of tablets you may take in a 24-hour period. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take naratriptan exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
You may take your first dose of naratriptan in a doctor's office or other medical facility where you can be monitored for serious reactions.
Call your doctor if your headaches do not get better or occur more frequently after taking naratriptan.
If you take naratriptan more often or for longer than the recommended period of time, your headaches may get worse or may occur more frequently. You should not take naratriptan or any other headache medication for more than 10 days per month. Call your doctor if you need to take naratriptan to treat more than four headaches in a 1-month period.
Ask your pharmacist or doctor for a copy of the manufacturer's information for the patient.
