Naratriptan

  • One tablet should be taken at the onset of a migraine attack. If your migraine is not eased after this first dose, do not take a second dose for the same attack. If your migraine goes away but then returns, you may take a second tablet at least four hours after the initial dose. No more than two tablets should be taken in 24 hours.
  • Naratriptan, along with the symptoms of migraine, can cause drowsiness. Make sure you know how you react to this medicine before driving, operating machinery or doing any other jobs which could be dangerous if you were not fully alert. Avoid alcohol as this will increase any feelings of drowsiness.
  • Important: You may also experience sensations of tingling, heat, pain, heaviness, pressure or tightness in any part of the body, including the throat and chest. These sensations may be strong but usually do not last long. If they continue or become too intense, stop taking Naratriptan and contact your doctor as soon as possible.

About naratriptan

Type of medicine 5HT1 Agonist
Used for Migraine
Also called Naramig®
Available as Tablets

It is thought that the widening of blood vessels in the brain causes the pain associated with migraine. The blood vessels widen on release of a chemical called serotonin. Naratriptan works by binding to receptors in the brain to prevent serotonin from binding. This causes the blood vessels to narrow and relieves the pain felt during a migraine.

Before taking naratriptan

Before taking naratriptan make sure your doctor or pharmacist knows:

  • If you are pregnant, trying for a baby or breast-feeding.
  • If you suffer from heart, liver or kidney problems.
  • If you suffer from angina, including Prinzmetal's angina, hypertension (high blood pressure), circulatory problems such as Raynaud's disease or if you have ever suffered a heart attack or stroke.
  • If you have been taking any medicines already for migraine that contain another 5HT1 agonist (almotriptan, eletriptan, frovatriptan, rizatriptan, sumatriptan or zolmitriptan) or ergotamine.
  • If you have ever had an allergic reaction to this or any other medicine, particularly the antibiotics co-trimoxazole or sulfadiazine.
  • If you are taking any other medicines, including those available to buy without a prescription, herbal and complementary medicines.
  • Naratriptan is not recommended in patients under 18 or over 65 years of age.
