说  明   
功用作用   1.Naratriptan is a headache medicine. It is believed to work by causing vasoconstriction (narrowing) of arteries and veins that supply blood to your head.
2.Naratriptan is used to treat vascular headaches such as migraine headaches.
3.Naratriptan may also be used for purposes other than those listed in this medication guide.
用法用量   1.Take naratriptan tablets exactly as directed by your doctor. If you do not understand these directions, ask your pharmacist, nurse, or doctor to explain them to you.
2.Take each dose with a full glass of water.
3.Naratriptan may be taken with or without food.
4.Take one tablet as soon as you notice symptoms of a migraine, or at any time during an attack.
5.If your symptoms do not improve, call your doctor before taking any more doses of naratriptan.
6.If your symptoms improve only partially, or if they go away and then return, you can take another dose of naratriptan unless your doctor directs otherwise. The second dose must be taken 4 hours or more after the first one. Never take more than 5 mg (2 tablets) in any 24-hour period.
7.Store naratriptan at room temperature away from moisture, heat, light, and the reach of children.
8.Throw away any unused medicine on the expiration date.
注意事项   1.Do not take naratriptan if the headache you are experiencing is not like other migraines that you have had.
2.Do not take this medication if you have angina (chest pain) or if you have had a heart attack.
3.Never take more of this medication than is prescribed by your doctor. If your symptoms are not being treated, contact your doctor.
If Miss a Dose: 1.Since naratriptan is taken to treat migraine headaches as they occur and not to prevent them, missing a dose is not a problem. Take only the doses you need according to your doctor's instructions.
Contraindications: 1.You cannot take naratriptan if you

*have ischemic bowel disease or Raynaud syndrome;
*are experiencing a headache that is not like other migraines that you have had;

*have taken an ergot-based medication within the last 24 hours--ergot-based medicines include methysergide (Sansert), ergotamine (Ergostat, Medihaler Ergotamine), dihydroergotamine mesylate (D.H.E.), and ergotamine combination products (Cafergot, Ercaf, Wigraine, Cafatine, Cafatine-PB, Cafetrate).

4.You may not be able to take naratriptan, or you may require a dosage adjustment or special monitoring during treatment if you have any of the conditions listed above.
5.Naratriptan is in the FDA pregnancy category C. This means that it is not known whether naratriptan will harm an unborn baby. Do not take this medication without first talking to your doctor if you are pregnant.
6.It is also not known whether naratriptan passes into breast milk. Do not take naratriptan without first talking to your doctor if you are breast-feeding a baby.
7.The FDA has not approved naratriptan for use by children younger than 18 years of age.
8.If you are over 65 years of age, you may be more likely to experience side effects from naratriptan. You may not be able to take this medication.

2.Never take more of this medication than is prescribed by your doctor.
