What does it do?

Rizatriptan is used to treat migraines.

How should you take it?

Take rizatriptan as directed at the start of migraine symptoms. Place it on your tongue and allow it to dissolve, then swallow.
Do not take more than one tablet for the same migraine.

Can you take other medicines?

Some medicines available without a prescription may react with rizatriptan 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 (e.g. ecstasy).
