Compazine belongs to a group of medications called phenothiazines. It is used to treat severe nausea and vomiting, schizophrenia, anxiety. The drug blocks or lessens the effects of dopamine, a chemical in the brain. Dopamine may be elevated in people with schizophrenia or anxiety. Compazine is not a cure for schizophrenia or anxiety; it only helps to control symptoms of these conditions. Since dopamine can activate the part of the brain that controls nausea and vomiting, this medication can treat severe nausea and vomiting by lessening the effects of dopamine in the brain.
Take Compazine exactly as prescribed by your doctor. The recommended starting dose for schizophrenia is 5 mg or 10 mg three or four times daily. The recommended dose for severe nausea and vomiting is 5 mg to 10 mg three to four times daily. The usual dose for anxiety is 5 mg three to four times daily. It should not be used at doses higher than 20 mg per day or for longer than 12 weeks. For schizophrenia treatment in children ages 2 to 12, the recommended starting dose is 2.5 mg two or three times daily. It should not be used for nausea and vomiting in pediatric surgery. Your doctor may occasionally change your dose to make sure you get the best results from this medication.
Before taking Compazine you should talk with your doctor if you have breathing problems (asthma, or emphysema), glaucoma, enlarged prostate (benign prostatic hyperplasia), difficulty passing urine, any allergies, heart disease, high blood pressure, liver or kidney disease, Parkinson's disease, infectious disease (chickenpox, measles), breast cancer, low levels of calcium in your blood. Compazine may impair your thinking or reactions. Do not drive or perform tasks that require alertness. Avoid drinking alcohol as it can increase some of the side effects. Compazine should not be used in children younger than two years of age.
Do not use Compazine if you have brain damage, bone marrow depression, or are also using large amounts of alcohol or medicines that make you sleepy. Do not use it if you are allergic to prochlorperazine or other phenothiazines. Let your doctor know if you are pregnant or breastfeeding.
