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.

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.

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 Nauseti
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.
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.

- dry mouth
- trembling, rigid posture, mask-like face, slow movements and a shuffling unbalanced walk

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

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.
