1. What is Risperidona Stada and what is it used for

Risperidona belongs to a group of medications called “antipsychotics”.

Risperidona is used to treat the following:

• Schizophrenia, with which you may see, hear, or feel things that are not there, believe in something that is not true, or feel particularly suspicious, or confused.
• Mania, with which you may feel very excited, elated, agitated, enthusiastic, or hyperactive. Mania occurs in a disease called “bipolar disorder”.
• Short-term treatment (up to 6 weeks) of persistent aggression in people with Alzheimer's dementia, who harm themselves or others. Other alternative treatments (non-pharmacological) should have been tried previously.
• Short-term treatment (up to 6 weeks) of persistent aggression in intellectually disabled children (at least 5 years old) and adolescents with behavioral disorders.

Risperidona may help reduce the symptoms of your illness and prevent them from coming back.

2. What you need to know before taking Risperidona Stada

Do not take Risperidona Stada:

• If you are allergic to risperidona or any of the other components of this medication (listed in section 6).

If you are not sure, consult your doctor or pharmacist before starting to take risperidona.

Warnings and precautions

Consult your doctor or pharmacist before taking risperidona if:

• You have any heart problems. Examples include heart rhythm disorders or if you are prone to having low blood pressure or if you use medications for blood pressure. Risperidona may lower your blood pressure. You may need to have your dose adjusted.
• You know of any factor that may make you prone to having a stroke, such as high blood pressure, cardiovascular disease, or problems with the blood vessels in the brain.
• You have ever had involuntary movements of the tongue, mouth, and face.
• You have ever had symptoms that include fever, muscle stiffness, sweating, or a decrease in the level of consciousness (also known as Neuroleptic Malignant Syndrome).
• You have Parkinson's disease or dementia.
• If you have had low levels of white blood cells in the past (which may or may not have been caused by other medications).
• You are diabetic.
• You have epilepsy.
• You are male and have ever had a prolonged or painful erection.
• You have problems controlling your body temperature or feel excessive heat.
• 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 tumor that may be dependent on prolactin.
• You or a family member have a history of blood clot problems, as antipsychotics have been associated with the formation of blood clots.

If you have doubts about whether what you have read affects you, consult your doctor or pharmacist before taking risperidona.

Because in very rare cases, a dangerously low number of a type of white blood cell necessary to fight infections in the blood has been observed in patients treated with risperidona, your doctor may check your white blood cell count.

Risperidona may cause you to gain weight. A significant weight gain can affect your health unfavorably. Your doctor will regularly monitor your weight.

Because diabetes mellitus or a worsening of pre-existing diabetes mellitus has been seen in patients taking risperidona, your doctor should check for signs of elevated blood sugar. In patients with pre-existing diabetes mellitus, blood sugar should be regularly monitored.

Risperidona often increases the levels of a hormone called prolactin. This can cause side effects such as menstrual disorders or fertility problems in women or breast swelling in men (see Possible side effects). If these side effects appear, it is recommended to evaluate the levels of prolactin in the blood.

During eye surgery for cataracts, the pupil (the black circle in the middle of the eye) may not increase in size as needed. Additionally, the iris (the colored part of the eye) may become flaccid during surgery, which can cause damage to the eye. If you are considering eye surgery, make sure to inform your ophthalmologist that you are using this medication.

Elderly patients with dementia

In elderly patients with dementia, there is an increased risk of having a stroke. You should not take risperidona if you have dementia caused by a stroke.

During treatment with risperidona, you should see your doctor frequently.

If you or your caregiver notice a sudden change in your mental state or the sudden appearance of weakness or numbness in the face, arms, or legs, especially on one side, or confused speech, even if only for a short time, seek medical attention immediately. It may be a sign of a stroke.

Children and adolescents

Other causes of aggressive behavior should be ruled out before starting treatment for behavioral disorders.

If during treatment with risperidona you experience fatigue, changing the administration times may improve your difficulties in paying attention.

Before starting treatment, your weight or your child's weight may be measured and followed regularly during treatment.

A small, inconclusive study has reported an increase in height in children who took risperidona, but it is unknown whether this is an effect of the medication or due to another reason.

Other medications and Risperidona Stada

Tell your doctor or pharmacist if you are taking, have recently taken, or may take any other medication.

It is especially important that you talk to your doctor or pharmacist if you take any of the following:

• Medications that act on your brain, such as those used to calm down (benzodiazepines), or some pain medications (opioids), allergy medications (some antihistamines), as risperidona may increase their sedative effect.
• Medications that can modify the electrical activity of your heart, such as those used for malaria, heart rhythm problems, allergies (antihistamines), some antidepressants, or other medications for mental problems.
• Medications that cause a slow heartbeat.
• Medications that cause low potassium levels in the blood (such as some diuretics).
• Medications for high blood pressure. Risperidona may lower blood pressure.
• Medications for Parkinson's disease (such as levodopa).
• Medications that increase the activity of the central nervous system (psychostimulants, such as methylphenidate).
• Diuretics, which are used for heart problems or to treat swelling in some parts of the body due to fluid retention (such as furosemide or chlorthiazide). Risperidona, taken alone or with furosemide, may increase the risk of stroke or death in elderly patients with dementia.

The following medications may decrease the effect of risperidona

• Rifampicin (a medication for treating some infections).
• Carbamazepine, phenytoin (medications for epilepsy).
• Phenobarbital.

If you start or stop taking these medications, you may need a different dose of risperidona.

The following medications may increase the effect of risperidona

• Quinidine (used for certain types of heart disease).
• Antidepressants such as paroxetine, fluoxetine, tricyclic antidepressants.
• Medications known as beta-blockers (used to treat high blood pressure).
• Phenothiazines (such as medications used to treat psychosis or as sedatives).
• Cimetidine, ranitidine (stomach acid blockers).
• Itraconazole and ketoconazole (medications used to treat fungal infections).
• Some medications used to treat HIV/AIDS, such as ritonavir.
• Verapamil, a medication used to treat high blood pressure and/or abnormal heart rhythm.
• Sertraline and fluvoxamine, medications used to treat depression and other psychiatric disorders.

If you start or stop taking these medications, you may need a different dose of risperidona.

If you have doubts about whether what you have read affects you, consult your doctor or pharmacist before taking risperidona.

Taking Risperidona Stada with food, drinks, and alcohol

You can take this medication with or without food. You should avoid consuming alcohol while taking risperidona.

Pregnancy, breastfeeding, and fertility

• If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before taking this medication. Your doctor will decide if you can take it.
• The following symptoms may occur in newborn babies of mothers who have been treated with risperidona in the last trimester of pregnancy (last three months of pregnancy): tremors, stiffness and/or muscle weakness, drowsiness, agitation, breathing problems, and difficulty feeding. If your baby develops any of these symptoms, you should contact your doctor.
• Risperidona may increase the levels of a hormone called “prolactin” that can affect fertility (see Possible side effects).

Driving and using machines

Risperidona may cause symptoms such as drowsiness, dizziness, or vision changes, and may reduce your reaction ability. These effects, as well as the underlying disease, may make it difficult for you to drive vehicles or operate machines. Therefore, do not drive, operate machines, or engage in other activities that require special attention until your doctor assesses your response to this medication.
