What Rizatriptan ODT GH is used for

Rizatriptan ODT GH are used to relieve headache pain and other symptoms of migraine attacks. Rizatriptan ODT GH 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, eg. cheese and other dairy products, chocolate, citrus fruit, caffeine, alcohol (especially red wine);
  • stress, anger, worry;
  • changes in routine, eg. under or over sleeping, missing a meal, change in diet;
  • bright light or loud noises;
  • hormonal changes in women, eg. 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 ODT GH has been prescribed for you.

How Rizatriptan ODT GH works

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

How to take Rizatriptan ODT GH

Follow all directions given to you by your doctor carefully. They may differ from the information contained in this leaflet.

If you do not understand the instructions on the box, ask your doctor or pharmacist for help.

How much to take

Take Rizatriptan ODT GH only when prescribed by your doctor.

The usual dose to treat a migraine is one 10 mg Rizatriptan ODT GH orally disintegrating tablet.

If the first Rizatriptan ODT GH orally disintegrating tablet does help your migraine, but it comes back later, you may take another orally disintegrating tablet.

Take the second orally disintegrating tablet at least 2 hours after the first. Do not take more than 30 mg (three 10 mg orally disintegrating tablets) in a 24-hour period.

If the first Rizatriptan ODT GH orally disintegrating tablet does not help your migraine, do not take another orally disintegrating tablet for the same attack as it is unlikely to help. It is still likely, however, that you will respond to Rizatriptan ODT GH during your next attack.

You should not take Rizatriptan ODT GH 10 mg while you are taking propranolol.

How to take it

Do not to remove the orally disintegrating tablet from the blister until just prior to dosing.

With dry hands push the orally disintegrating tablet through the foil and place the orally disintegrating tablet on your tongue. The orally disintegrating tablet will dissolve rapidly and be swallowed with your saliva. No water is needed for taking the orally disintegrating tablet.

It does not matter if you take Rizatriptan ODT GH before or after food.

If you take too much (overdose)

Immediately telephone your doctor or Poisons Information Centre (telephone 13 11 26) for advice, or go to accident and emergency at your nearest hospital, if you think that you or anyone else may have taken too many Rizatriptan ODT GH tablets. Do this even if there are no signs of discomfort or poisoning.

If you take too many orally disintegrating tablets, you may feel sleepy, dizzy, faint or have a slow heartbeat.

While you are taking Rizatriptan ODT GH

Things you must do

If your headache is more severe than your ‘usual’ migraine or it behaves differently, tell your doctor.

If you are about to be started on any new medicine, tell your doctor and pharmacist that you take Rizatriptan ODT GH for migraines.

Things you must not do

Do not give Rizatriptan ODT GH to anyone else, even if they have the same condition as you.

Things to be careful of

Be careful driving or operating machinery until you know how Rizatriptan ODT GH affects you. Migraine or treatment with Rizatriptan ODT GH may cause sleepiness or dizziness in some people. Make sure you know how you react to Rizatriptan ODT GH before you drive a car, operate machinery, or do anything else that could be dangerous if you are sleepy or dizzy. If you drink alcohol, sleepiness or dizziness may be worse.
