Stemetil 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.
Stemetil is used to treat nausea, vomiting and dizziness due to various causes, including migraine (severe headache).
Your doctor may have prescribed Stemetil for another reason.

If you have not told your doctor or pharmacist about any of the above, tell them before you start taking Stemetil.

Your doctor and pharmacist may have more information on medicines to be careful with or avoid while taking Stemetil.
Follow all directions given to you by your doctor and pharmacist carefully. They may differ from the information contained in this leaflet.
If you do not understand the instructions on the pack, ask your doctor or pharmacist for help.
Your doctor or pharmacist will tell you how much Stemetil you will need to take each day. This depends on your condition and whether or not you are taking any other medicines.
The usual recommended dose for nausea and vomiting is 1 or 2 tablets two to three times daily. If you are not able to take a tablet, then one 25mg suppository or a 1mL (12.5mg) injection is the recommended dose.
The usual recommended dose for dizziness is 1 or 2 tablets three to four times daily.
The recommended dose for nausea, vomiting and dizziness is 1 tablet two to three times a day.
Swallow Stemetil tablets whole with a full glass of water. Do not chew the tablets.
Stemetil may be given as an injection into a muscle. Stemetil injection should only be given by a doctor, nurse or other trained person.
It does not matter if you take Stemetil before or after food.
If you are not sure what to do, ask your doctor or pharmacist.
If you have trouble remembering to take your medicine, ask your pharmacist for some hints.
Continue taking Stemetil for as long as your doctor tells you.
Do not try to vomit.
Immediately telephone your doctor or pharmacist or the Poisons Information Centre (telephone 13 11 26) or go to Accident and Emergency at your nearest hospital if you think that you, or anyone else, has taken too much Stemetil. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
Symptoms of overdose may include the following:
Your doctor or pharmacist has information on how to recognise and treat an overdose. Ask your doctor or pharmacist if you have any concerns.
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 Stemetil.
The condition is more likely to occur during long term treatment with Stemetil, 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 Stemetil.
If you are about to be started on any new medicines, tell your doctor, dentist or pharmacist that you are taking Stemetil.
If you plan to have surgery that needs a general anaesthetic, tell your doctor or dentist that you are taking Stemetil.
If you become pregnant while taking Stemetil, tell your doctor immediately.
Do not give Stemetil to anyone else, even if they have the same condition as you.
Do not take Stemetil to treat any other complaints unless your doctor or pharmacist tells you to.
Do not stop taking Stemetil, or lower the dosage, even if you are feeling better, without checking with your doctor. If you stop taking Stemetil suddenly, your condition may worsen or your chance of getting an unwanted side effect may increase. To prevent this, your doctor may gradually reduce the amount of Stemetil you take each day before stopping completely.
Be careful driving or operating machinery until you know how Stemetil affects you. As with other medicines, Stemetil may cause dizziness, light-headedness, tiredness, drowsiness in some people.
Make sure you know how you react to Stemetil 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 light-headedness may be worse.
If Stemetil 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 Stemetil. Combining Stemetil and alcohol can make you more sleepy, dizzy or light-headed. Your doctor may suggest you avoid alcohol while you are being treated with Stemetil.
If outdoors, wear protective clothing and use at least a 15+ sunscreen. Stemetil 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. 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. Stemetil 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 Stemetil. Stemetil helps most people with nausea, vomiting and dizziness, but it may have unwanted side effects in a few people.
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.
If you get any side effects, do not stop taking Stemetil without first talking to your doctor or pharmacist.
Tell your doctor or pharmacist if you notice any of the following and they worry you:
The following side effects are less common:
If any of the following happen, tell your doctor or pharmacist immediately or go to Accident and Emergency at your nearest hospital:
These are very serious side effects.
You may need urgent medical attention or hospitalisation.
Other side effects not listed above may occur in some patients. Tell your doctor or pharmacist if you notice anything that is making you feel unwell.
Do not be alarmed by this list of possible side effects. You may not experience any of them.
Stemetil ampoules for injection should be stored at a pharmacy or hospital. The injection should be kept below 25°C and protected from light.
Keep Stemetil suppositories in a cool dry place where the temperature stays below 25°C. Protect from light.
Keep Stemetil tablets in a cool dry place where the temperature stays below 30°C. Protect from light.
Keep your Stemetil in the pack until it is time to take them. If you take the tablets or suppositories out of the pack, they may not keep well.
Do not store Stemetil or any other medicine in the bathroom or near a sink.
Do not leave it in the car on hot days or on window sills. Heat and dampness can destroy some medicines.
Keep it where children cannot reach it. A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.
