It is very important that your doctor should check the progress of you and your child at regular visits to make sure prochlorperazine is working properly. Blood tests may be needed to check for unwanted effects.
Check with your doctor before using prochlorperazine with alcohol or other medicines that affect the central nervous system (CNS). The use of alcohol or other medicines that affect the CNS with risperidone may worsen the side effects of prochlorperazine, such as dizziness, poor concentration, drowsiness, unusual dreams, and trouble with sleeping. Some examples of medicines that affect the CNS are antihistamines or medicine for allergies or colds, sedatives, tranquilizers, or sleeping medicines, medicine for depression, medicine for anxiety, prescription pain medicine or narcotics, medicine for attention deficit and hyperactivity disorder, medicine for seizures or barbiturates, muscle relaxants, or anesthetics, including some dental anesthetics.
Prochlorperazine may cause extrapyramidal symptoms. Check with your doctor right away if you have difficulty in speaking, drooling, loss of balance control, muscle trembling, jerking, or stiffness, restlessness, shuffling walk, stiffness of the limbs, twisting movements of the body, or uncontrolled movements, especially of the face, neck, and back.
Prochlorperazine may cause drowsiness, trouble with thinking, or trouble with controlling body movements, which may lead to falls, fractures or other injuries. Make sure you know how you react to prochlorperazine before you drive, use machines, or do other jobs that require you to be alert, well-coordinated, or able to think or see well.
Dizziness, lightheadedness, or fainting may occur, especially when you get up suddenly from a lying or sitting position. Getting up slowly may help. If this problem continues or gets worse, check with your doctor.
Prochlorperazine may make it more difficult for your body to cool itself down. Use care not to become overheated during exercise or hot weather since overheating may result in heat stroke. Also, use extra care not to become too cold while you are receiving risperidone injection. If you become too cold, you may feel drowsy, confused, or clumsy.
Make sure any doctor or dentist who treats you knows that you are using prochlorperazine. Prochlorperazine may affect the results of certain medical tests.
Prochlorperazine may cause tardive dyskinesia (a movement disorder). Check with your doctor right away if you have any of the following symptoms while using prochlorperazine: lip smacking or puckering, puffing of the cheeks, rapid or worm-like movements of the tongue, uncontrolled chewing movements, or uncontrolled movements of the arms and legs.
Check with your doctor right away if you have any of the following symptoms while using prochlorperazine: convulsions (seizures), difficulty with breathing, a fast heartbeat, a high fever, high or low blood pressure, increased sweating, loss of bladder control, severe muscle stiffness, unusually pale skin, or tiredness. These could be symptoms of a serious condition called neuroleptic malignant syndrome (NMS).
Prochlorperazine can temporarily lower the number of white blood cells in your blood, increasing the chance of getting an infection. If you can, avoid people with infections. Check with your doctor immediately if you think you are getting an infection or if you get a fever or chills, cough or hoarseness, lower back or side pain, or painful or difficult urination.
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
