USES Promazine is prescribed to treat the symptoms of certain types of mental illness, such as emotional symptoms of psychosis, the manic phase of manic-depressive illness, and severe behavioral problems in children. It is thought to relieve symptoms of mental illness by blocking certain chemicals involved with nerve transmission in the brain. TREATMENT To avoid stomach irritation, you can take this medication with a meal or with a glass of water or milk (unless your doctor directs you to do otherwise). If you miss a dose of this medication, take the missed dose as soon as possible, unless it is almost time for your next dose. In that case, do not take the missed dose at all; just return to your regular dosing schedule. Do not double the dose (unless your doctor directs you to do so). Antacids and antidiarrheal medicines may decrease the absorption of this medication from the gastrointestinal tract. Therefore, at least one hour should separate doses of one of these medicines and promazine. The full effects of this medication for the control of emotional or mental symptoms may not become apparent until two weeks after you start to take it. SIDE EFFECTS Minor. Blurred vision, constipation, decreased sweating, diarrhea, dizziness, drooling, drowsiness, dry mouth, fatigue, jitteriness, menstrual irregularities, nasal congestion, restlessness, vomiting, or weight gain. As your body adjusts to the medication, these side effects should disappear. Promazine can also cause discoloration of the urine to red, pink, or red-brown. This is a harmless effect. This medication can cause increased sensitivity to sunlight. It is, therefore, important to avoid prolonged exposure to sunlight and sunlamps. Wear protective clothing and sunglasses, and use an effective sunscreen. If you are constipated, increase the amount of fiber in your diet (raw fruits and vegetables, salads, bran, and whole-grain breads), exercise, and drink more water (unless your doctor directs you to do otherwise). Chew sugarless gum or suck on ice chips or a piece of hard candy to reduce mouth dryness. To avoid dizziness or light-headedness when you stand, contract and relax the muscles of your legs for a few moments before rising. Do this by pushing one foot against the floor while raising the other foot slightly, alternating feet so that you are "pumping" your legs in a pedaling motion. Major. Tell your doctor about any side effects that are persistent or particularly bothersome. IT IS ESPECIALLY IMPORTANT TO TELL YOUR DOCTOR about unusual bleeding or bruising; breast enlargement (in both sexes); chest pain; convulsions; darkened skin; difficulty in swallowing or breathing; fainting; fever; impotence; involuntary movements of the face, mouth, jaw, or tongue; palpitations; rash; sleep disorders; sore throat; tremors; uncoordinated movements; visual disturbances; or yellowing of the eyes or skin. INTERACTIONS This medication interacts with a number of other types of medications: 1. It can cause extreme drowsiness when combined with alcohol or other central nervous system depressants (drugs that slow the activity of the brain and spinal cord), such as barbiturates, benzodiazepine tranquilizers, muscle relaxants, narcotics, and pain medications, or with tricyclic antidepressants. 2. Promazine can decrease the effectiveness of amphetamines, guanethidine, anticonvulsants, and levodopa. 3. The side effects of epinephrine, monoamine oxidase (MAO) inhibitors, propranolol, phenytoin, and tricyclic antidepressants may be increased by this medication. 4. Lithium may increase the side effects and decrease the effectiveness of this medication. Before starting to take promazine, BE SURE TO TELL YOUR DOCTOR about any medications you are currently taking, especially any of those listed above. WARNINGS Tell your doctor about unusual or allergic reactions you have had to any medications, especially to promazine or other phenothiazine tranquilizers (such as chlorpromazine, fluphenazine, mesoridazine, perphenazine, prochlorperazine, thioridazine, trifluoperazine, and triflupromazine) or to loxapine. Tell your doctor if you have a history of alcoholism or if you now have or have ever had any blood disease, bone marrow disease, brain disease, breast cancer, blockage in the urinary or digestive tracts, drug-induced depression, epilepsy, high or low blood pressure, diabetes mellitus, glaucoma, heart or circulatory disease, liver disease, lung disease, Parkinson's disease, peptic ulcers, or an enlarged prostate gland. Tell your doctor about any recent exposure to a pesticide or an insecticide. Promazine may increase the side effects from the exposure. To prevent oversedation, avoid drinking alcoholic beverages while taking this medication. If this medication makes you dizzy or drowsy, do not take part in any activity that requires alertness, such as driving a car or operating potentially dangerous machinery. Be careful on stairs, and avoid getting up suddenly from a lying or sitting position. Prior to having surgery or any other medical or dental treatment, be sure to tell your doctor or dentist that you are taking this medication. Some of the side effects caused by this drug can be prevented by taking an antiparkinsonism drug. Discuss this with your doctor. This medication can decrease sweating and heat release from the body. You should, therefore, try not to get overheated (avoid strenuous exercise in hot weather and do not take hot baths, showers, and saunas). Do not stop taking this medication suddenly. If the drug is stopped abruptly, you may experience nausea, vomiting, stomach upset, headache, increased heart rate, insomnia, tremors, or a worsening of your condition. Your doctor may, therefore, want to reduce the dosage gradually. If you are planning to have a myelogram, or any other procedure in which dye will be injected into the space surrounding your spinal cord, tell your doctor that you are taking this medication. While taking this medication, do not take any over-the-counter (nonprescription) medication for weight control or for cough, cold, allergy, asthma, or sinus problems unless you first check with your doctor. The combination of these medications may cause high blood pressure. Be sure to tell your doctor if you are pregnant. Small amounts of this medication cross the placenta. Although there are reports of safe use of this drug during pregnancy, there are also reports of liver disease and tremors in newborn infants whose mothers received this medication close to term. Also, tell your doctor if you are breast-feeding an infant. Small amounts of this medication pass into breast milk and may cause unwanted effects in nursing infants. ---------------- The material contained here is "FOR INFORMATION ONLY" and should not replace the counsel and advice of your personal physician.
