  • so called positive symptoms:- hallucinations, such as feeling, seeing or hearing things which do not exist

    • strange and/or frightening thoughts
    • changes in your behaviour, which can be agressive
  • so called negative symptoms:

    • becoming withdrawn and subdued

2. What you need to know before you take Amisulpride

Do not take Amisulpride

if you are/have

  • allergic to amisulpride or any of the other ingredients of this medicine (listed in section 6).
  • breast cancer or something called “prolactin-dependent tumour”
  • a tumour on the adrenal gland
  • a child before the onset of puberty
  • taking

    levodopa: a medicine to treat Parkinson’s disease

    -

Warnings and Precautions

Talk to your doctor or pharmacist before taking Amisulpride if:

  • you are developing fever, faster breathing, excessive sweating, reduced consciousness or stiff muscles which are symptoms of a severe – potentially fatal – disorder called “neuroleptic malignant syndrome”. Stop immediately taking Amisulpride and contact your doctor.

    See also section 4, first paragraph

  • you have high blood sugar levels - diabetes mellitus - or are at risk of developing it

    If you do, your doctor may check your blood sugar levels while you are taking Amisulpride.

  • you have kidney function disorder

    See section “3 How to take Amisulpride”

  • you have ever suffered from fits

    If you have epilepsy you may experience more frequent fits during treatment with Amisulpride.Your doctor will need to monitor you more closely.

  • you are over 65 years old

    Elderly people are more likely to get low blood pressure or feel sleepy during therapy with Amisulpride. A small increase in the number of deaths of elderly people with dementia has been reported for patients taking antipsychotics compared to those not receiving antipsychotics.

  • you have Parkinson’s disease
  • you have a low number of white blood cells, so called agranulocytosis. This means that you may get infections more easily than usual. A medical specialist, haematologist, should be consulted if this occurs.
  • you have frequent unexplained infections such as fever, severe chills, sore throat or mouth ulcers. These could be signs of a blood problem (leucopenia, neutropenia) and might require the consultation of a doctor specialized in haematology.
  • you have heart disease or a family history of heart problems, such as heart failure or irregular heart beat, especially an abnormality known as “prolonged QT-interval”
  • you have had a stroke previously or are at risk of stroke
  • you or someone else in your family has a history of blood clots, as medicines like these have been associated with formation of blood clots
  • you or someone else in your family has a history of breast cancer. A strict medical follow up is needed during treatment with Amisulpride.
  • you have high levels of prolactin. This can lead to swelling of breasts and unexpected production of breast milk in men and women and to no monthly or irregular periods in women. You must stop taking Amisulpride if this is confirmed by your doctor after a blood test.

Severe liver problems have been reported with Amisulpride. Talk to your doctor immediately if you experience fatigue, loss of appetite, nausea, vomiting, abdominal pain or yellow discoloration of the eyes or skin.

The recommended dose is:

Adults (and adolescents after the onset of puberty, if treatment is absolutely required)

If you suffer from positive symptoms, the usual dose is between 400 mg and 800 mg amisulpride daily, and will be adjusted individually by your doctor depending on the nature and severity of your illness. The maximum daily dose is 1,200 mg.

If you suffer from both positive and negative symptoms, your doctor will adjust your dose individually so that there is adequate control of the positive symptoms. To maintain treatment, your doctor will use the lowest possible dose that is effective for you.

If you suffer from negative symptoms, the usual dose is between 50 mg and 300 mg amisulpride daily, and will be adjusted individually by your doctor depending on the nature and severity of your illness.

Amisulpride tablets can be divided into equal doses.
