Rizatriptan

About rizatriptan

Rizatriptan is used to treat migraine attacks. Research has shown that migraine can be caused by the swelling of blood vessels around the brain. Rizatriptan eases the pain associated with migraine by narrowing these blood vessels. It also blocks the release of chemicals from nerves that cause symptoms of migraine.

Before taking rizatriptan

Before taking rizatriptan make sure your doctor or pharmacist knows:

• If you are pregnant, trying for a baby or breast-feeding.
• If you suffer from liver or kidney problems.
• If the patient is under 18 years of age.
• If you suffer from Prinzmetal's angina, hypertension (high blood pressure), or circulatory problems.
• If you have recently suffered a stroke or mini-stroke.
• If you have heart disease or have had a heart attack.
• If you have ever had an allergic reaction to this or any other medicine.
• If you are taking any other medicines, including those available to buy without a prescription, herbal or complementary medicines.

How to take rizatriptan

• Before beginning treatment, read the manufacturer's printed information leaflet.
• Take rizatriptan exactly as directed by your doctor.
• Rizatriptan wafers must be placed on the tongue and allowed to dissolve in the mouth.
• Take/use one tablet or wafer at the onset of an attack. If your migraine returns, one tablet or wafer may be taken two hours after the initial dose. If your migraine is not eased after the first dose is taken, do not take the second dose.
• Do not take more than two tablets/wafers in 24 hours.
• Rizatriptan is for you. Never give it to others, even if their condition appears to be the same as yours.

Getting the most from your treatment

• Rizatriptan should not be used in combination with migraine treatments containing ergotamine. If you have been taking an ergotamine preparation you must leave a gap of 24 hours before taking rizatriptan. A gap of 24 hours after taking rizatriptan is also needed before taking ergotamine. If in doubt ask your doctor or pharmacist.
• Prolonged use of any painkiller for headaches can make them worse. If you continue to have frequent headaches, contact your doctor for further advice.
• Before taking any 'over-the-counter' medicines, check with your pharmacist which medicines are safe for you to take alongside rizatriptan.
