- Mania, where you may feel very excited, elated, agitated, enthusiastic or hyperactive. Mania occurs in an illness called “bipolar disorder”
- Short-term treatment (up to 6 weeks) of long-term aggression in people with Alzheimer’s dementia, who harm themselves or others. Alternative (non-drug) treatments should have been used previously
- Short-term treatment (up to 6 weeks) of long-term aggression in intellectually disabled children (at least 5 years of age) and adolescents with conduct disorder.
Risperidone can help alleviate the symptoms of your disease and stop your symptoms from coming back.

- You know of any factors which would favour you having a stroke, such as high blood pressure,cardiovascular disorder or blood vessel problems in the brain
- You have ever experienced involuntary movements of the tongue, mouth and face.
- You have ever had a condition whose symptoms include high temperature, muscle stiffness, sweating, or a lowered level of consciousness (also known as Neuroleptic Malignant Syndrome).
- You have Parkinson’s disease or dementia
- You know that you have had low levels of white blood cells in the past (which may or may not have been caused by other medicines)
- You are diabetic
- You have epilepsy
- You are a man and you have ever had a prolonged or painful erection
- You have problems controlling your body temperature or overheating
- You have kidney problems
- You have liver problems
- You have an abnormally high level of the hormone prolactin in your blood or if you have a tumour, which is possibly dependent on prolactin.
- You or someone else in your family has a history of blood clots, as antipsychotics have been associated with formation of blood clots.
If you are not sure if any of the above applies to you, talk to your doctor or pharmacist before using Risperidone Tablets.
As dangerously low numbers of a certain type of white blood cell needed to fight infection in your blood has been seen very rarely with patients taking Risperidone Tablets, your doctor may check your white blood cell counts.
Risperidone Tablets may cause you to gain weight. Significant weight gain may adversely affect your health. Your doctor should regularly measure your body weight. As diabetes mellitus or worsening of pre-existing diabetes mellitus have been seen with patients taking Risperidone Tablets, your doctor should check for signs of high blood sugar. In patients with pre-existing diabetes mellitus blood glucose should be monitored regularly.
Risperidone Tablets commonly raises levels of a hormone called "prolactin". This may cause side effects such as menstrual disorders or fertility problems in women, breast swelling in men (see Possible side effects). If such side effects occur, evaluation of the prolactin level in the blood is recommended.
During an operation on the eye for cloudiness of the lens (cataract), the pupil (the black circle in the middle of your eye) may not increase in size as needed. Also, the iris (the coloured part of the eye) may become floppy during surgery and that may lead to eye damage. If you are planning to have an operation on your eye, make sure you tell your eye doctor that you are taking this medicine.

Medical treatment should be sought straight away if you or your care-giver notice a sudden change in your mental state or sudden weakness or numbness of your face, arms or legs, especially on one side, or slurred speech, even for a short period of time. These may be signs of a stroke.
Children and adolescents
Before treatment is started for conduct disorder, other causes of aggressive behaviour should have been ruled out.
If during treatment with risperidone tiredness occurs, a change in the time of administration might improve attention difficulties.
Before treatment is started your, or your child's body weight may be measured and it may be regularly monitored during treatment.
A small and inconclusive study has reported an increase in height in children who took risperidone, but whether this is an effect of the drug or due to some other reason is not known.
