Stemetil (prochlorperazine) is a medication that is used to treat nausea and vomiting of various causes, including migraine.
It usually works within an hour of taking it and it can be taken up to three times in 24 hours if needed. It works best if you take it as soon as your symptoms begin.
Common side effects when using this as required for migraine include blurred vision, drowsiness and slowed reaction times. As a result, you should not drive or operate machinery when taking this and avoid alcohol as this makes side effects more likely.
If you experience other symptoms that you feel are related to this medication, speak with your pharmacist or a doctor.
It is important to read the information leaflet that comes with your medication for full details of side effects.
There is a very rare risk of a serious condition called neuroleptic malignant syndrome. This causes high temperature, fast heart rate, sweating and confusion and requires URGENT medical assessment (call 999).
