-

-
- INGREDIENT
-
- perphenazine
-
- DOSAGE FORMS
-
- Tablets (2 mg, 4 mg, 8 mg, and 16 mg)
- Oral concentrate (16 mg per 5-ml spoonful, with less than 0.1% alcohol)
-
- STORAGE
-
- The tablet forms of this medication should be stored at room temperature
- in tightly closed, light-resistant containers. The oral concentrate form may
- be stored in the refrigerator in a tightly closed, light-resistant container.
- If the oral concentrate turns slightly yellow, the medicine is still effective
- and can be used. However, if it changes color markedly or has particles
- floating in it, it should not be used; rather, it should be discarded down the
- sink. This medication should never be frozen.
-
- USES
-
- Perphenazine is prescribed to treat the symptoms of certain types of
- mental illness, such as psychosis, the manic phase of manic-depressive
- illness, and severe behavioral problems in children. This medication is
- thought to relieve the symptoms of mental illness by blocking certain
- chemicals involved with the transmission of nerve impulses in the brain.
-
- TREATMENT
-
- To avoid stomach irritation, you can take the tablet form of this
- medication with a meal or with a glass of water or milk (unless your doctor
- directs you to do otherwise).
- The oral concentrate form of this medication should be measured carefully
- with the dropper provided, then added to four ounces (1/2 cup) or more of
- water, milk, or a carbonated beverage or to applesauce or pudding immediately
- prior to administration. To prevent possible loss of effectiveness, do not
- dilute this drug in tea, coffee, or apple juice.
- Antacids and antidiarrheal medicines may decrease the absorption of this
- medication from the gastrointestinal tract. Therefore, at least an hour
- should separate doses of one of these medicines and perphenazine.
- If you miss a dose, take the missed dose as soon as possible, then return
- to your regular dosing schedule. If it is almost time for the next dose,
- however, skip the one you missed and return to your regular schedule. Do not
- double the next dose (unless your doctor directs you to do so).
- The full effects of this medication for the control of emotional or
- mental symptoms may not become apparent for 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 drug, these side effects should disappear.
- Perphenazine can also cause discoloration of the urine--a harmless side
- effect. The urine may become red, pink, or red-brown.
- 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 (fresh
- 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
- 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; unusual bleeding or
- bruising; visual disturbances; weakness; or yellowing of the eyes or skin.
-
- INTERACTIONS
-
- Perphenazine interacts with several other types of drugs:
- 1. It can cause extreme drowsiness when combined with alcohol or other
- central nervous system (brain and spinal cord) depressants, such as
- barbiturates, benzodiazepine tranquilizers, muscle relaxants, narcotics, and
- pain medications or with tricyclic antidepressants.
- 2. Perphenazine 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. At least 14 days should separate the use of this drug and the use
- of an MAO inhibitor.
- 4. Lithium may increase the side effects and decrease the effectiveness
- of this medication.
- Before starting to take perphenazine, BE SURE TO TELL YOUR DOCTOR about
- any medications you are currently taking, especially any of those listed
- above.
-
- WARNINGS
-

- sitting position.
- * Before 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 exercising strenuously
- in hot weather and taking 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.

- (nonprescription) medications for weight control or for cough, cold, allergy,
- asthma, or sinus problems without first checking with your doctor.
- * 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 type of 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 the
