- USES
-
- Promethazine is prescribed for a wide range of conditions. Promethazine
- belongs to a group of drugs known as antihistamines, which block the action of
- histamine, a chemical that is released by the body during an allergic
- reaction. It is, therefore, used to treat or prevent symptoms of allergy or
- hay fever. Promethazine also (1) works at the vomiting center in the brain
- and can be used for the prevention or treatment of nausea and vomiting; (2) is
- a central nervous system (brain and spinal cord) depressant, which produces
- light sleep or mild sedation; and (3) prevents motion sickness.
-
- TREATMENT
-
- To avoid stomach irritation, you can take the tablet or oral syrup form
- of this medication with a meal or with a glass of water or milk (unless your
- doctor directs otherwise).
- Measure the oral syrup carefully with a specially designed 5-ml measuring
- spoon. An ordinary kitchen teaspoon is not accurate enough.
- To use the suppository, remove the foil wrapper (if the suppository is
- too soft to insert, refrigerate it for half an hour or run cold water over it
- before removing the wrapper), and moisten the suppository with water. Lie on
- your left side with your right knee bent. Push the suppository into the
- rectum, pointed end first. Lie still for a few minutes. Try to avoid having
- a bowel movement for at least an hour (to give the medication time to be
- absorbed).
- If you are taking this medication regularly and you miss a dose, take the
- missed dose as soon as possible, unless it is almost time for the next dose.
- In that case, do not take the missed dose at all; just return to your regular
- schedule. Do not double the next dose (unless your doctor directs you to do
- so).
-
- SIDE EFFECTS
-
- Minor.
-
- Blurred vision, diarrhea, dizziness, drowsiness, dry mouth,
- light-headedness, nausea, or vomiting. These side effects should disappear as
- your body adjusts to this drug.
- 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.
- To reduce mouth dryness, chew sugarless gum or suck on ice chips or hard
- candy.
- 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
- alternately pushing one foot against the floor while raising the other foot
- slightly, 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
- confusion; disorientation; involuntary movements of the face, mouth, jaw, or
- tongue; rash; uncoordinated movements; unusual bleeding or bruising; or
- yellowing of the eyes or skin.
-
- INTERACTIONS
-
- Promethazine interacts with other types of medications:
- 1. Promethazine 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. Promethazine can decrease the effectiveness of amphetamines,
- guanethidine, anticonvulsants, and levodopa.
- 3. The side effects of epinephrine, monoamine oxidase (MAO) inhibitors,
- propranolol, and tricyclic antidepressants may be increased by this
- medication. At least 14 days should separate the use of this medication and
- the use of an MAO inhibitor.
- TELL YOUR DOCTOR about any of the medications you are currently taking,
- especially any of those listed above.
-
- WARNINGS
-
- * Tell your doctor about any unusual or allergic reactions you have had
- to any medications, especially to promethazine or any chemically related
- phenothiazine drug (chlorpromazine, fluphenazine, mesoridazine, perphenazine,
- prochlorperazine, promazine, thioridazine, trifluoperazine, triflupromazine).
- * Before starting promethazine, tell your doctor if you now have or if
- you have ever had asthma, blockage of the urinary or digestive tract, diabetes
- mellitus, enlarged prostate gland, epilepsy, glaucoma, heart disease, liver
- disease, peptic ulcers, or sleep apnea.
- * 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 going up and down stairs.
- * 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.
- * 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
- newborns whose mothers received this medication close to term. Also, tell
- your doctor if you are breast-feeding. Small amounts of this medication pass
- into breast milk and may cause unwanted effects in nursing infants, such as
- sudden infant death syndrome (SIDS) or sleep apnea.
