What happens if I miss a dose (Risperdal)?
Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.
What happens if I overdose (Risperdal)?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
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 may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert.
Avoid getting up too fast from a sitting or lying position, or you may feel dizzy. Get up slowly and steady yourself to prevent a fall.
Drinking alcohol can increase certain 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, Equetro, Tegretol);
- cimetidine (Tagamet) or ranitidine (Zantac);
- clozapine (Clozaril);
- fluoxetine (Prozac, Sarafem, Symbyax) or paroxetine (Paxil);
- phenytoin (Dilantin) or valproic acid (valproate, Depakene, Stavzor);
- phenobarbital (Solfoton);
- 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 other drugs may interact with risperidone. Tell your doctor about all medications you use. This includes prescription, over-the-counter, vitamin, and herbal products. Do not start a new medication without telling your doctor.
