What does it do?

Naratriptan is used to treat migraines.

How should you take it?

Take naratriptan as directed when your symptoms first start. Take with a large glass of water.

If your symptoms get better, but then return, you can take another dose after 4 hours.
If naratriptan does not help, do not take any further doses for the same attack, as it is unlikely to work. You can still use naratriptan for a new attack.
Do not take more than the maximum daily dose advised by your doctor.

Can you take other medicines?

Some medicines available without a prescription may react with naratriptan including:

  • cold and flu medicines containing dextromethorphan (e.g. Robitussin Dry Cough Forte®)

Tell your pharmacist or doctor about all medicines or treatments that you may be taking, including vitamins, herbal products (e.g. St John's wort) or recreational drugs.

What side effects might you notice?

Other information:

  • Tell your health professional if you have heart or blood vessel problems, high blood pressure, or if you have ever had a stroke, or 'mini-stroke'.
  • Tell your doctor if you are pregnant, planning to become pregnant, or breastfeeding.
  • Tell your doctor if you need to use naratriptan several times each week. Using naratriptan too often can cause a different type of headache. Your doctor can talk with you about different medicines that are taken every day to prevent migraines.
  • Do not use naratriptan to prevent migraines.
  • Naratriptan can impair your ability to do tasks such as driving or using machines. Alcohol makes this worse. Discuss your risk with your health professional. (search NZTA - Are you safe to drive?)
