1. WHAT RISPERIDONE ORAL SOLUTION IS AND WHAT IT IS USED FOR
Risperidone is one of a group of medicines called antipsychotics.
Risperidone is used to treat the following:
• Schizophrenia, where you may see, hear or feel things that are not there, believe things that are not true or feel unusually suspicious, or confused.
• 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 six 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 six weeks) of long-term aggression in intellectually disabled children (at least five years of age) and adolescents with conduct disorder.
2. BEFORE YOU TAKE RISPERIDONE ORAL SOLUTION
Do not take Risperidone Oral Solution if:
• you are allergic (hypersensitive) to risperidone or any of the other ingredients of Risperidone Oral Solution (see ‘Further information' section).
If you are not sure if the above applies to you, talk to your doctor or pharmacist before using Risperidone Oral Solution.
Take special care with Risperidone Oral Solution:
Check with your doctor or pharmacist before taking Risperidone Oral Solution if:
• you have a heart problem. Examples include an irregular heart rhythm or if you are prone to low blood pressure or if you are using medicines for your blood pressure. Risperidone Oral Solution may cause low blood pressure. Your dose may need to be adjusted.
• 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 Parkinson's disease or dementia
• you have liver problems
• you have kidney problems
• you suffer from diabetes
• you suffer from epilepsy
• You are a man and you have ever had a prolonged or painful erection. If you experience this while taking Risperidone Oral Solution, contact your doctor straight away
• you have problems controlling your body temperature or overheating
• 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 medicines like these have been associated with formation of blood clots.
Tell your doctor immediately if you experience
• involuntary rhythmic movements of the tongue, mouth and face. Withdrawal of risperidone may be needed
• fever, severe muscle stiffness, sweating or a lowered level of consciousness (a disorder called “neuroleptic malignant syndrome”). Immediate medical treatment may be needed.
If you are not sure if any of the above applies to you, speak to your doctor or pharmacist before taking Risperidone Oral Solution.
Risperidone Oral Solution may cause you to gain weight.
Elderly people with dementia
In elderly patients with dementia, there is an increased risk of stroke. You should not take risperidone if you have dementia caused by stroke.
During treatment with risperidone you should frequently see your doctor.
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 in conduct disorder, other causes of aggressive behaviour should have been ruled out.
Before treatment is started your, or your child's body weight may be measured and it may be regularly monitored during treatment.
If during treatment with risperidone tiredness occurs, a change in the time of administration might improve attention difficulties.
Taking other medicines
Please tell your doctor if you are taking or have recently taken any other medicines, including medicines obtained without a prescription and herbal medicines.
It is especially important to talk to your doctor or pharmacist if you are taking any of the following:
• medicines that work on your brain to help you calm down (benzodiazepines) or some medicines for pain (opiates), medicines for allergy (some antihistamines), as risperidone may increase the sedative effect of all of these
• medicines that may change the electrical activity of your heart, such as medicines for malaria, heart rhythm problems (such as quinidine), allergies (antihistamines), some antidepressants or other medicines for mental health problems
• medicines that cause a slow heart beat
• medicines that cause low blood potassium (e.g. certain diuretics)
• medicines to treat elevated blood pressure. Risperidone can lower blood pressure
• medicines for Parkinson's disease (such as levodopa)
• water tablets (diuretics) used for heart problems or swelling of parts of your body due to a build up of too much fluid (such as furosemide or chlorothiazide). Risperidone taken by
itself or with furosemide, may have an increased risk of stroke or death in elderly people with dementia
The following medicines may reduce the effect of risperidone:
• rifampicin (a medicine for treating some infections)
• carbamazepine, phenytoin (medicines for epilepsy)
• phenobarbital
If you start or stop taking such medicines you may need a different dose of risperidone
The following medicines may increase the effect of risperidone:
• quinidine (used for certain types of heart disease)
• antidepressants such as paroxetine, fluoxetine, tricyclic antidepressants
• medicines known as beta blockers (used to treat high blood pressure)
• phenothiazines (e.g. used to treat psychosis or to calm down)
• cimetidine, ranitidine (blockers of the acidity of the stomach)
If you start or stop taking such medicines you may need a different dose of risperidone
If you are not sure if any of the above applies to you, talk to your doctor or pharmacist before using risperidone.
Taking Risperidone Oral Solution with food and drink
You should be careful how much alcohol you drink as the combined effect of risperidone and alcohol may make you feel drowsy.
Risperidone Oral Solution can be taken with or without food.
Pregnancy and breast-feeding
• talk to your doctor before using Risperidone Oral Solution if you are pregnant, trying to become pregnant or are breast-feeding. Your doctor will decide if you can take it
• shaking, muscle stiffness and problems feeding, all of which are reversible, have been seen in newborn babies when risperidone was used during the last trimester of pregnancy.
The following symptoms may occur in newborn babies, of mothers that have used Risperidone in the last trimester (last three months of their pregnancy): shaking, muscle stiffness and/or weakness, sleepiness, agitation, breathing problems, and difficulty in feeding.
