What Rizatriptan AN ODT is used for

Rizatriptan AN ODT is used to relieve the headache pain and other symptoms of migraine attacks. Rizatriptan AN ODT does 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 AN ODT has been prescribed for you.

How Rizatriptan AN ODT works

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

Taking other medicines

Tell your doctor if you are taking any other medicines, herbal products, or dietary supplements, including those that you buy without a prescription from your pharmacy, supermarket or health food shop.

Some medicines should not be taken with Rizatriptan AN ODT. These include:

  • monoamine oxidase inhibitors (MAOIs) used to treat depression, including moclobemide, tranylcypromine, phenelzine, pargyline

  • methysergide, a medicine used to prevent migraine
  • St. John's wort (Hypericum perforatum), a herbal product sold as a dietary supplement, or products containing St. John's wort

These medicines, herbal products, or dietary supplements may be affected by Rizatriptan AN ODT, or may affect how well it works. You may need different amounts of your medicine, you may need to take different medicines or you may need to be careful of the timing of some of these medicines.

How to take Rizatriptan AN ODT

How much to take

Take Rizatriptan AN ODT only when prescribed by your doctor.

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

If the first Rizatriptan AN ODT 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 AN ODT 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 AN ODT during your next attack.

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

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.
