What is in this leaflet

This leaflet answers some common questions about SULPRIX. It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.

What SULPRIX is used for

SULPRIX contains the active ingredient called amisulpride.

SULPRIX belongs to a group of medicines called antipsychotics. SULPRIX is used to treat symptoms of schizophrenia.

Schizophrenia is a condition which affects the way you think, feel and/or act. Schizophrenia may cause symptoms such as hallucinations (e.g. hearing, seeing or sensing things which are not there), delusions, unusual suspiciousness, emotional and social withdrawal. People with schizophrenia may also feel depressed, anxious or tense.

Your doctor may have prescribed it for another reason.

Ask your doctor if you have any questions about why this medicine has been prescribed for you.

How much to take

Your doctor will tell you how many SULPRIX tablets you should take.

SULPRIX should preferably be taken before meals.

How long to take it

Do not stop taking SULPRIX unless your doctor tells you.

Do not stop taking SULPRIX because you feel better.

This medicine helps to control your condition but does not cure it. It is important to keep taking your medicine even if you feel well.

If you forget to take it

If you forget to take your medicine, take your dose as soon as you remember.

Do not take a double dose to make up for the dose that you missed. This may increase the chance of you getting an unwanted side effect.

If you take too much (overdose)

Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice, or go to Accident and Emergency at the nearest hospital, if you think that you or anyone else may have taken too much SULPRIX.

While you are taking SULPRIX

Things you must do

If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking SULPRIX.

  • any recent attempts of self-harm
  • increase in aggressive behaviour, irritability or agitation

Things you must not do

Do not take SULPRIX 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.

Things to be careful of

SULPRIX may cause drowsiness in some people.

Be careful driving or operating machinery until you know how SULPRIX affects you. Some people may have slower reflexes, experience drowsiness or blurred vision while taking SULPRIX.

Be careful if you are elderly or unwell. Some people may experience side effects like drowsiness, confusion, dizziness and unsteadiness which may increase the risk of fall, sometimes leading to fractures. SULPRIX may affect your ability to move or balance.

Be careful when drinking alcohol while you are taking this medicine. The effects of alcohol could be made worse while taking SULPRIX. It is not recommended that you drink alcohol while taking SULPRIX.

Be careful while taking antihistamines, sleeping tablets or tablets to relieve pain while taking this medicine. SULPRIX can increase drowsiness caused by medicines affecting your nervous system.

Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking SULPRIX.
