What MAXALT Wafers are used for

MAXALT Wafers are used to relieve the headache pain and other symptoms of migraine attacks. MAXALT Wafers 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 MAXALT has been prescribed for you.

How MAXALT Wafers work

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

Before you start to take it

Tell your doctor if:

  1. you are pregnant or intend to become pregnant
    Like most medicines, MAXALT Wafers are not recommended for use during pregnancy. If there is a need to consider MAXALT Wafers during pregnancy, your doctor will discuss with you the risks and benefits of taking them during pregnancy.
  2. you are breast-feeding or plan to breast-feed
    It is not known whether MAXALT Wafers pass into breast milk. Your doctor will discuss with you the risks and benefits of taking them while breast-feeding.
  3. you have any risks factors for heart or blood vessel disease, including:
  • high blood pressure
  • diabetes
  • smoking
  • a high cholesterol level
  • a family history of heart or blood vessel disease
  1. your headache is more severe than your 'usual' migraine, or it behaves differently
  2. you have a condition called phenylketonuria
    The 5mg wafer* contains 1.05mg phenylalanine (a component of aspartame) and the 10mg wafer contains 2.10mg phenylalanine.
  3. you have, or have had, any other medical conditions
  4. you have any allergies to any other medicines or any other substances, such as foods, preservatives or dyes.

If you have not told your doctor about any of the above, tell them before you take any MAXALT Wafers.

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 MAXALT Wafers. These include:

  • monoamine oxidase inhibitors (MAOIs) used to treat depression, including moclobemide, tranylcypromine, phenelzine, pargyline
  • sumatriptan, another similar medicine used to treat migraine

Some medicines, herbal products, or dietary supplements, and MAXALT Wafers may interfere with each other. These include:

  • propranolol, a medicine used to treat high blood pressure
  • ergotamine, dihydroergotamine, other medicines used to treat migraine
  • 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 MAXALT Wafers, 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.

Ask your doctor for instructions about taking MAXALT Wafers if you are also taking selective serotonin reuptake inhibitors (SSRIs) such as sertraline, escitalopram oxalate, and fluoxetine or serotonin norepinephrine reuptake inhibitors (SNRIs) such as venlafaxine, and duloxetine for depression.

Your doctor or pharmacist has more information on medicines to be careful with or avoid while taking MAXALT Wafers.

How to take MAXALT Wafers

How much to take

Take MAXALT Wafers only when prescribed by your doctor.

The usual dose to treat a migraine is one 10 mg wafer.

If the first MAXALT Wafer does help your migraine, but it comes back later, you may take another wafer.

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 MAXALT 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 MAXALT during your next attack.

You should not take MAXALT 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.

How to take it

With dry hands place the wafer on your tongue. The wafer will dissolve rapidly and be swallowed with your saliva. No water is needed for taking the wafer.

It does not matter if you take MAXALT Wafers 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 MAXALT Wafers. Do this even if there are no signs of discomfort or poisoning.

If you take too many wafers, you may feel sleepy, dizzy, faint or have a slow heart beat.

While you are using MAXALT Wafers

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 MAXALT Wafers for migraines.

If you become pregnant while taking MAXALT Wafers, tell your doctor immediately.

Things you must not do

Do not give MAXALT Wafers 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 MAXALT Wafers affect you. Migraine or treatment with MAXALT Wafers may cause sleepiness or dizziness in some people. Make sure you know how you react to MAXALT Wafers 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.

  • seizures, fits or convulsions
  • persistent purple discolouration, and/or pain in the fingers, toes, ears, nose or jaw
  • pain or spasms in the lower stomach, bloody diarrhoea and fever

These are serious side effects. You may need urgent medical attention. Serious side effects are rare.

As with other medicines in the same class as MAXALT, heart attack, angina and stroke have been reported very rarely, and generally occurred in people with risk factors for heart or blood vessel disease (including high blood pressure, diabetes, smoking, family history of heart or blood vessel disease e.g. stroke).

Other side effects not listed above may also occur in some patients. Tell your doctor if you notice any other effects.

Do not be alarmed by this list of possible side effects. You may not experience any of them.

After using MAXALT Wafers


Keep your blister containing each individual wafer in the aluminium sachet until it is time to take it. Each wafer is packed in a blister within an outer aluminium sachet. If you take the wafer out of the blister and PVC/PVDC/Al sachet, it may not keep well.

Keep MAXALT Wafers in a cool dry place where the temperature stays below 30°C. Do not store them or any other medicine in the bathroom or near a sink.

Do not leave them in the car or on window sills. Heat and dampness can destroy some medicines.

Keep them where children cannot reach them. A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.


If your doctor tells you to stop taking the wafers, or the wafers have passed their expiry date, ask your pharmacist what to do with any that are left over.
