Risperdal Patient Information including If I Miss a Dose

What happens if I miss a dose (Risperdal)?

Take the missed dose as soon as you remember. If it is almost time for your next dose, skip the missed dose and take the medicine at the next regularly scheduled time. Do not take extra medicine to make up the missed dose.

What happens if I overdose (Risperdal)?

Seek emergency medical treatment if you think you have used too much of this medicine.

Overdose symptoms may include drowsiness, fast heart rate, feeling light-headed, fainting, and restless muscle movements in your eyes, tongue, jaw, or neck.

What should I avoid while taking risperidone (Risperdal)?

While you are taking risperidone, you may be more sensitive to temperature extremes such as very hot or cold conditions. Avoid getting too cold, or becoming overheated or dehydrated. Drink plenty of fluids, especially in hot weather and during exercise. It is easier to become dangerously overheated and dehydrated while you are taking risperidone.

Risperidone can cause side effects that may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be awake and alert.

Avoid drinking alcohol. It can increase some of the side effects of risperidone.

What other drugs will affect risperidone (Risperdal)?

Before you take risperidone, tell your doctor if you regularly use other medicines that make you sleepy (such as cold or allergy medicine, narcotic pain medicine, sleeping pills, muscle relaxers, and medicine for seizures, depression, or anxiety). They can add to sleepiness caused by risperidone.

Also tell your doctor if you are taking any of the following medicines:

carbamazepine (Carbatrol, Tegretol);
phenytoin (Dilantin);
phenobarbital (Luminal, Solfoton);
clozapine (Clozaril);
fluoxetine (Prozac) or paroxetine (Paxil);
rifampin (Rifadin, Rimactane, Rifater); or
medicines used to treat Parkinson's Disease such as levodopa (Dopar, Larodopa, Sinemet, Atamet, others), bromocriptine (Parlodel, others), pergolide (Permax), pramipexole (Mirapex), or ropinirole (Requip).

This list is not complete and there may be other drugs that can interact with risperidone. Tell your doctor about all the prescription and over-the-counter medications you use. This includes vitamins, minerals, herbal products, and drugs prescribed by other doctors. Do not start using a new medication without telling your doctor.

Where can I get more information?

Your pharmacist can provide more information about risperidone.

Remember, keep this and all other medicines out of the reach of children, never share your medicines with others, and use this medication only for the indication prescribed.
