What this medicine is used for
Rizatriptan is used to relieve the headache pain and other symptoms of migraine attacks.
Rizatriptan does not work for other types of headaches.
Migraine is an intense, throbbing, typically one-sided headache.
It often includes nausea, vomiting, and sensitivity to light or sound.
Some people may have visual symptoms before the headache, called an aura.
An aura can include flashing lights or wavy lines.
Migraine attacks last anywhere from two hours to two days and they can return frequently.
The severity and frequency of migraines may vary.
Migraine occurs in about one out every 10 people.
It is three times more common in women than men.
Six out of ten migraine sufferers have their first attack before the age of 20.
There is no single cause of migraine.
They tend to run in families.
Certain things trigger migraine attacks in some people, including:
- certain foods or drinks e.g. cheese, dairy products, chocolate, citrus fruit, caffeine, alcohol (especially red wine)
- stress, anger, worry
- changes in routine e.g. under or over sleeping, missing meals, change in diet
- bright light or loud noises
- hormonal changes in women e.g. during menstrual periods.
If you understand what triggers your attacks, you may be able to prevent migraine attacks or reduce their frequency.
Keeping a headache diary will help you identify and monitor possible migraine triggers.
Once the triggers are identified, you and your doctor can modify your treatment and lifestyle appropriately.
How it works
During a migraine attack, blood vessels in the brain dilate, or widen, resulting in a throbbing pain.
Rizatriptan decreases this widening and returns the blood vessels to their normal size, helping to relieve the pain.
Rizatriptan also blocks the release of certain chemicals from nerve endings that cause more pain and other symptoms of migraine.
Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed this medicine for another reason.
This medicine is available only with a doctor's prescription.
This medicine is not addictive.
There is not enough information to recommend the use of this medicine for children under the age of 18 years.
