How it works
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.
Use in children
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. Tell your doctor that you are taking this medicine if:
- You become pregnant
- You are about to have any blood tests
You are planning to have surgery and you are taking this medicine. 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.
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.
Tell any other doctors, dentists, and pharmacists who are treating you that you are taking prochlorperazine.
Things you must not do
- Give this medicine to anyone else, even if their symptoms seem similar to yours.
- Take your medicine to treat any other condition unless your doctor tells you to.
- 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 prochlorperazine 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.
