What Prochlorperazine AN is used for

Prochlorperazine AN 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.

Prochlorperazine AN is used to treat nausea, vomiting and dizziness due to various causes, including migraine (severe headache).

Your doctor may have prescribed Prochlorperazine AN for another reason.

Ask your doctor if you have any questions about why Prochlorperazine AN has been prescribed to you. This medicine is available only with a doctor’s prescription.

These are symptoms of a very rare condition called Tardive Dyskinesia, which may develop in people taking phenothiazine medicine, including Prochlorperazine AN.

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

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

Do not stop taking Prochlorperazine AN, or lower the dosage, even if you are feeling better, without checking with your doctor.

To prevent this, your doctor may gradually reduce the amount of Prochlorperazine AN you take each day before stopping completely.

Your doctor may check your eyes, thyroid, lipid and blood glucose levels.

Tell your doctor if, for any reason, you have not taken your medicine exactly as prescribed. Your doctor may think it is not working effectively and change your treatment unnecessarily.

Things to be careful of

Be careful driving or operating machinery until you know how Prochlorperazine AN affects you. As with other medicines, Prochlorperazine AN may cause dizziness, lightheadedness, tiredness, drowsiness in some people. Make sure you know how you react to Prochlorperazine AN before you drive a car, operate machinery, or do anything else that could be dangerous if you are dizzy or light-headed. If this occurs do not drive. If you drink alcohol, dizziness or lightheadedness may be worse.

If Prochlorperazine AN 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 AN.

Combining Prochlorperazine AN 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 AN.

If outdoors, wear protective clothing and use at least a 15+ sunscreen. Prochlorperazine AN 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 AN may affect the way your body reacts to temperature changes.

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. If you are over 65 years of age you may have an increased chance of getting side effects.

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