What is in this leaflet

This leaflet answers some common questions about Nausetil. It does not contain all the available information.

It does not take the place of talking to your doctor or pharmacist.

All medicines have risks and benefits. Your doctor or pharmacist has weighed the risks of you taking Nausetil against the benefits they expect it will have for you.

What NAUSETIL is used for

Nausetil contains the active ingredient prochlorperazine maleate and is used to treat nausea associated with migraine (severe headache).

Nausetil belongs to a group of medicines called phenothiazines, which help to correct chemical imbalances in the brain allowing it to function correctly. These chemicals may also affect the parts of the brain which control nausea.

There is no evidence that it is addictive.

How to take it

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

How much to take

Your doctor or pharmacist will tell you how much Nausetil you will need to take each day. This depends on your condition and whether or not you are taking any other medicines.

For adults, the usual recommended dose is 1 or 2 tablets two to three times daily. For acute treatment, 4 tablets at once, followed if necessary by 2 tablets two hours later, may be taken.

Children (over the age of two (2) years or over 10 kg), the elderly or patients who have a pre-existing liver condition may need to take fewer tablets.

How to take it

Swallow the tablet whole with a full glass of water.

Do not chew the tablet.

When to take it

It does not matter if you take Nausetil before or after food.

If you take too much (overdose)

Do not try to vomit.

Immediately telephone your doctor or pharmacist or the 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 much Nausetil. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.

Symptoms of overdose may include the following:

  • coma
  • restlessness, shaking, muscle twitching, muscle weakness, spasm
  • confusion
  • excitement or agitation
  • low blood pressure
  • fast heart beat
  • decrease in body temperature
  • small pupils in the eye
  • difficulty in swallowing or breathing
  • blue skin.

While you are taking it

Things you must do

Tell your doctor immediately if you notice any uncontrolled movements of the tongue, face, mouth or jaw, such as puffing of the cheeks, puckering of the mouth or chewing movements. These are symptoms of a very rare condition called tardive dyskinesia, which may develop in people taking phenothiazine medicines, including Nausetil.

The condition is more likely to occur during long term treatment, especially in elderly women. In very rare cases, this may be permanent.

Tell any other doctors, dentists and pharmacists who are treating you that you are taking Nausetil.

If you are about to be started on any new medicines, tell your doctor, dentist or pharmacist that you are taking Nausetil.

If you plan to have surgery that needs a general anaesthetic, tell your doctor or dentist that you are taking this medicine.

Tell your doctor or pharmacist immediately if you become pregnant while taking Nausetil.

Things you must not do

Do not give Nausetil to children under the age of two (2) years or under 10 kg in weight.

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

Do not take it to treat any other complaints unless your doctor or pharmacist tells you to.

Things to be careful of

Be careful driving or operating machinery until you know how Nausetil affects you. As with other medicines, Nausetil may cause dizziness, light-headedness, tiredness and drowsiness in some people, especially in the first few days of treatment.

If Nausetil makes you feel light-headed, dizzy or faint, get up slowly from a sitting or lying position.

Be careful when drinking alcohol while taking Nausetil. If you drink alcohol, dizziness or light-headedness may be worse.

Your doctor or pharmacist may suggest you avoid alcohol while you are being treated with Nausetil.

If outdoors, wear protective clothing and use at least a 15+ sunscreen. Nausetil may cause your skin to be much more sensitive to sunlight than it is normally. Exposure to sunlight may cause a skin rash, itching, redness or severe sunburn.

Make sure you keep cool in hot weather and keep warm in cool weather. Nausetil may affect the way your body reacts to temperature changes.

Side effects

Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking Nausetil. Nausetil helps most people with nausea associated with migraine, but it may have unwanted side effects in a few people.

All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical treatment if you get some of the side effects.

Ask your doctor or pharmacist to answer any questions you may have.

Tell your doctor or pharmacist if you notice any of the following common side effects and they worry you:

  • constipation
  • dry mouth
  • drowsiness
  • restlessness
  • trembling, rigid posture, mask-like face, slow movements and a shuffling unbalanced walk
  • twitching
  • blurred vision.

The following side effects are less common:

  • dizziness, light-headedness
  • changes in heart beat
  • swelling of the hands, ankles or feet
  • itchy skin rash
  • for females: unusual secretion of breast milk, irregular periods
  • for males: breast enlargement, difficulty in ejaculating
  • severe pain in the stomach with bloating, gut cramps and vomiting
  • difficulty passing urine
  • yellowing of the skin and/or eyes
  • headache
  • insomnia
  • seizures
  • difficulty in breathing
  • frequent infections such as fever, severe chills, sore throat or mouth ulcers
  • bleeding or bruising more easily than normal
  • excessive thirst
  • dry mouth and skin
  • changes in vision.

If any of the following happen, go to Accident and Emergency at your nearest hospital:

  • unusual muscle tone or spasms causing distortion of the body in children
  • chest pain and shortness of breath.

These are very serious side effects. Serious side effects are rare.

Tell your doctor or pharmacist if you notice anything else that is making you feel unwell. Other side effects not listed above may occur in some people.

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

After taking it


Keep your tablets in a cool dry place, protected from light where the temperature stays below 30°C.

Keep your tablets in the blister pack until it is time to take them. If you take the tablets out of the blister they may not keep as well.

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


Return any unused medicine to your pharmacist.
