What RIZATRIPTAN WAFERS-10mg are used for

RIZATRIPTAN WAFERS-10mg are used to relieve the headache pain and other symptoms of migraine attacks. RIZATRIPTAN WAFERS-10mg do not work for other types of headaches.
Migraine is an intense, throbbing, typically one-sided headache. It often includes nausea, vomiting, sensitivity to light, and sensitivity to 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 anything from two hours to two days and they can return frequently. The severity and frequency of migraine attacks may vary.
Migraine occurs in about one out of 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. It tends to run in families. Certain things, singly or in combination, can trigger migraine attacks in some people. Some of these triggers are:
certain foods or drinks, for example, cheese and other dairy products, chocolate, citrus fruit, caffeine, alcohol (especially red wine)
stress, anger, worry
changes in routine, for example, under or over sleeping, missing a meal, change in diet
bright light or loud noises
hormonal changes in women, for example, 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 all of the possible migraine triggers you encounter. Once the triggers are identified, you and your doctor can modify your treatment and lifestyle appropriately.
Ask your doctor if you have any questions about why RIZATRIPTAN WAFERS-10mg has been prescribed for you.

How RIZATRIPTAN WAFERS-10mg work

During a migraine attack, blood vessels in the brain dilate, or widen, resulting in a throbbing pain. RIZATRIPTAN WAFERS-10mg decrease this widening, returning the blood vessels to their normal size, and therefore helps to relieve the pain. RIZATRIPTAN WAFERS-10mg also block the release of certain chemicals from nerve endings that cause more pain and other symptoms of migraine.

How to take RIZATRIPTAN WAFERS-10mg

Take the second wafer at least 2 hours after the first. Do not take more than 30 mg (three 10 mg wafers) in a 24 hour period.
If the first RIZATRIPTAN WAFERS-10mg Wafer does not help your migraine, do not take another wafer for the same attack as it is unlikely to help. It is still likely, however, that you will respond to RIZATRIPTAN WAFERS-10mg during your next attack.
