What this medicine is used for
The name of your medicine is Terry White Chemists Rizatriptan Orally Disintegrating Tablets. It contains the active ingredient rizatriptan benzoate.
It is used to relieve the headache pain and other symptoms of migraine attacks.
Rizatriptan Orally Disintegrating Tablets 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 every 10 people. It is three times more common in women than men.
Six out of ten migraine sufferers 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, 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 meal, change in diet
- Bright light or loud noises
- Hormonal changes in women, 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 of the possible migraine triggers 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 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.
How it works
During a migraine attack, blood vessels in the brain dilate, or widen, resulting in a throbbing pain.
Rizatriptan decreases this widening, returning the blood vessels to their normal size, and therefore helps to relieve the pain. Rizatriptan also blocks the release of certain chemicals from nerve endings that cause more pain and other symptoms of migraine.
There is no evidence that this medicine is addictive
Use in children
This medicine should not be used in children.
The safety and effectiveness of rizatriptan in children under 18 years have not been established.
