  • RISPERIDONE 37.5mg

How do I take/use this medicine?

Risperidone Intramuscular injection is to be injected into the buttock muscles.

Your doctor or nurse will administer the injection for you. This injection will be made only ONCE every 2 weeks.

You may need to use Risperidone Intramuscular injection for some time before the full benefits can be felt. Do not be discouraged if you do not feel better soon after the injection has been given. It may take about 3 weeks for this injection to take effect. This is because the medicine is being released slowly from the site of injection. Over the long-term, this slow-release injection helps to give better control of your condition.

It is important that you continue with the injections even when you feel well. Do not stop using Risperidone Intramuscular injection unless your doctor has decided to do so. If this medicine is stopped suddenly, you may feel unwell or your condition may worsen. When your doctor decides that you do not need Risperidone Intramuscular injection anymore, he will usually reduce your dose slowly.

In order for you to get the most benefit from Risperidone Intramuscular injection, use it exactly as advised by your doctor. Do not use more or less than prescribed and do not skip any doses.

What should I take note of while using/taking this medicine?

Alert your doctor if you have any of these conditions:

- fits or a history of fits (epilepsy)
- Parkinson's disease
- Alzheimer's disease
- liver or kidney problems
- heart disease, including heart rhythm problems
- high blood pressure
- blocked intestines
- glaucoma (high pressure in the eyes)
- breast cancer or tumours dependent on a hormone called prolactin
- stroke, a history of stroke or transient ischaemic attacks (TIAs or "mini-strokes")
- diabetes (you will need to monitor your blood sugar level more closely)
- thoughts of harming or killing yourself

Risperidone may affect how your body adjusts to temperature changes. Avoid exposure to very cold or very hot environments.

When should I not use this medicine?

Alert your doctor if you are pregnant or if you become pregnant while being treated with Risperidone or within 12 weeks of the last injection.

Do not breastfeed while being treated with Risperidone and for 12 weeks after the last injection of Risperidone.

Risperidone is not suitable for elderly people with psychosis that is related to dementia.

Are there any restrictions on the type of food I can take?

Avoid alcohol. Alcohol will worsen the dizziness and drowsiness caused by Risperidone Intramuscular injection.

Why do I need this medicine?

Risperidone Intramuscular injection is used to treat schizophrenia. It helps to relieve symptoms common in schizophrenia, such as distorted thinking and emotional instability.

Risperidone Intramuscular injection is also used on its own or together with other medicines for the treatment of a dysfunctional mood condition called bipolar disorder.

What side effects could I experience?

Risperidone may make you drowsy or dizzy. If you feel drowsy or dizzy, do not drive or take part in any activity in which you need to be alert.

You may feel dizzy when getting up from a sitting or lying down position, especially if this is your first Risperidone Intramuscular injection, or if your doctor is still adjusting your dose. This dizziness is normal and should improve gradually as you get used to the medicine. It will help if you get up slowly from a sitting or lying down position.

Some common side effects with Risperidone Intramuscular injection include difficulty sleeping, headache, tiredness, weakness, agitation, anxiety, mood changes, constipation, weight gain, blocked nose, nausea and stomach discomfort. Inform your doctor if these side effects are severe or do not go away.

Other side effects are rare but may be serious and need immediate medical help. Alert your doctor immediately if you develop slurred speech with weakness or numbness in the face, arms or legs especially if it is only on one side of the body.

Alert your doctor immediately if you develop these group of symptoms:
- abnormal movements of your limbs

- abnormal breast growth in men
- impotence in men

Alert your doctor if you develop any of these side effects or if you develop any other side effects.
