Elderly patients with dementia

In elderly patients with dementia, there is an increased risk of stroke.

You should not take risperidone if your dementia is caused by a stroke.

During treatment with Risperidone Kern Pharma, you should see your doctor frequently.

If you or your caregiver notice a sudden change in your mental state or sudden onset of weakness or numbness in the face, arms, or legs—especially on one side—or confusion in speech, even if brief, seek immediate medical attention. These may be signs of a stroke.

Children and adolescents

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

If you experience fatigue during risperidone treatment, adjusting the time of administration may improve difficulties with attention.

Taking Risperidone Kern Pharma with other medicines

Inform your doctor or pharmacist if you are currently using, have recently used, or might need to use any other medicines.

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

• Medicines that act on the brain, such as those used to calm you (benzodiazepines), or some pain medications (opioids), or allergy medications (some antihistamines), as risperidone may increase their sedative effect.
• Medicines that can alter the electrical activity of your heart, such as those used for malaria, heart rhythm disorders (e.g., quinidine), allergies (antihistamines), some antidepressants, or other medicines for mental disorders.
• Medicines that cause a slow heart rate.
• Medicines that cause low potassium levels in the blood (e.g., some diuretics).
• Medicines for high blood pressure. Risperidone Kern Pharma may lower blood pressure.
• Medicines for Parkinson's disease (such as levodopa).
• Diuretics used for heart problems or to treat swelling in certain body parts due to fluid retention (e.g., furosemide or hydrochlorothiazide).

Risperidone Kern Pharma, taken alone or with furosemide, may increase the risk of stroke or death in elderly patients with dementia.

The following medicines may reduce the effect of risperidone:

• Rifampicin (a medicine used to treat certain infections).
• Carbamazepine, phenytoin (medicines for epilepsy).
• Phenobarbital.

If you start or stop taking these 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, and tricyclic antidepressants.
• Medicines known as beta-blockers (used to treat high blood pressure).
• Phenothiazines (e.g., used to treat psychosis or as sedatives).
• Cimetidine, ranitidine (stomach acid blockers).

If you start or stop taking these medicines, you may need a different dose of risperidone.

If you have any doubts about whether the above applies to you, consult your doctor or pharmacist before using Risperidone Kern Pharma.
