What this medicine is used for
The name of your medicine is APO-Prochlorperazine. It contains the active ingredient, prochlorperazine (as prochlorperazine maleate).
It is used to treat nausea, vomiting and dizziness due to various causes, including migraine (severe headache).
Prochlorperazine belongs to a group of medicines called phenothiazines. It helps 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 (feeling sick) and vomiting.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Your doctor may have prescribed this medicine for another reason.
This medicine is available only with a doctor’s prescription.
Prochlorperazine is not recommended for use in children (under the age of 2 years or children under 10 kg in weight).

While you are taking this medicine
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 prochlorperazine.
The condition is more likely to occur during long term treatment with prochlorperazine, especially in elderly women. In very rare cases, this may be permanent.
If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking this medicine.
Tell any other doctors, dentists, and pharmacists who treat you that you are taking this medicine.
If you are going to have surgery, tell the surgeon or anaesthetist that you are taking this medicine.
It may affect other medicines used during surgery.
If you become pregnant or start to breastfeed while taking this medicine, tell your doctor immediately.
If you have diabetes or are at risk of developing diabetes be sure to monitor your blood glucose levels carefully.
This medicine may affect blood glucose levels.
If you are about to have any blood tests, tell your doctor that you are taking this medicine.
Go to your doctor regularly for a check-up.
Your doctor may occasionally do tests to make sure the medicine is working and to prevent side effects.
Things you must not do
Do not take this medicine to treat any other complaints unless your doctor tells you to.
Do not give your medicine to anyone else, even if they have the same condition as you.
Do not stop taking your medicine or change the dosage without checking with your doctor.
Things to be careful of
Be careful while driving or operating machinery until you know how this medicine affects you.
Prochlorperazine may cause dizziness, light-headedness, tiredness, drowsiness in some people.
Make sure you know how you react to prochlorperazine before you drive a car, operate machinery, or do anything else that could be dangerous if you are tired, drowsy, dizzy or light-headed. If this occurs do not drive. If you drink alcohol, drowsiness, dizziness or light-headedness may be worse.
If prochlorperazine makes you feel light-headed, dizzy or faint, be careful when getting up from a sitting or lying position. Getting up slowly may help.
Be careful when drinking alcohol while taking prochlorperazine. Combining this medicine and alcohol can make you more sleepy, dizzy or light-headed.
Your doctor may suggest you avoid alcohol while you are being treated with prochlorperazine.
If outdoors, wear protective clothing and use at least a 15+ sunscreen.
Prochlorperazine 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 even severe sunburn. If your skin does appear to be burning, tell your doctor.
Make sure you keep cool in hot weather and keep warm in cool weather.
Prochlorperazine may affect the way your body reacts to temperature changes. For example if you swim in cold water your body may not be able to adjust your body temperature to keep you warm and you may get hypothermia.
