USES This medication belongs to a group of drugs known as antihistamines (antihistamines block the action of histamine, a chemical that is released by the body during an allergic reaction). It is used to treat or prevent symptoms of allergy. TREATMENT To avoid stomach upset, you can take dexchlorpheniramine with food or with a full glass of milk or water (unless your doctor directs you to do otherwise). The syrup form of this medication should be measured carefully with a specially designed 5-ml measuring spoon. An ordinary kitchen teaspoon is not accurate enough for medical applications and does not ensure that you receive the proper dose. The repeat-action tablet form of this medication should be swallowed whole. Breaking, chewing, or crushing these tablets destroys their sustained-release activity and may increase the side effects. 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 next dose. SIDE EFFECTS Minor. Blurred vision; confusion; constipation; diarrhea; difficult or painful urination; dizziness; dry mouth, throat, or nose; headache; irritability; loss of appetite; nausea; rash; restlessness; ringing or buzzing in the ears; stomach upset; or unusual increase in sweating. These side effects should disappear as your body adjusts to the medication. This medication can cause increased sensitivity to sunlight. It is, therefore, important to avoid prolonged exposure to sunlight and sunlamps. Wear protective clothing 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). If you experience mouth or throat dryness, you may wish to chew sugarless gum or suck on ice chips or a piece of hard candy to minimize these side effects. If you feel dizzy or light-headed, sit or lie down for a while; get up from a sitting or lying position slowly, and be careful on stairs. Major. Tell your doctor about any side effects that are persistent or particularly bothersome. IT IS ESPECIALLY IMPORTANT TO TELL YOUR DOCTOR about changes in menstruation, clumsiness, feeling faint, flushing of the face, hallucinations, seizures, shortness of breath, sleeping disorders, sore throat or fever, palpitations, tightness in the chest, unusual bleeding or bruising, or unusual tiredness or weakness. INTERACTIONS Dexchlorpheniramine interacts with several other types of medications: 1. Concurrent use of it with central nervous system depressants (such as alcohol, barbiturates, benzodiazepine tranquilizers, muscle relaxants, narcotics, pain medications, and phenothiazine tranquilizers) or with tricyclic antidepressants can cause extreme drowsiness. 2. Monoamine oxidase (MAO) inhibitors (such as isocarboxazid, pargyline, phenelzine, and tranylcypromine) can increase the side effects of this medication. At least 14 days should separate the use of this drug and the use of an MAO inhibitor. 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 dexchlorpheniramine or other antihistamines (such as astemizole, azatadine, brompheniramine, carbinoxamine, chlorpheniramine, clemastine, cyproheptadine, dimenhydrinate, dimethindene, diphenhydramine, diphenylpyraline, doxylamine, hydroxyzine, phenidamine, promethazine, pyrilamine, terfenadine, trimeprazine, tripelennamine, and triprolidine). * Tell your doctor if you now have or if you have ever had asthma, blood vessel disease, glaucoma, high blood pressure, kidney disease, peptic ulcers, enlarged prostate gland, or thyroid disease. * Dexchlorpheniramine can cause drowsiness or dizziness. Your ability to perform tasks that require alertness, such as driving a car or operating potentially dangerous equipment, may be decreased. Appropriate caution should, therefore, be taken. * Be sure to tell your doctor if you are pregnant. The effects of this medication during pregnancy have not been thoroughly studied in humans. It is recommended that use of this drug be avoided during the last three months of pregnancy. Also, tell your doctor if you are breast-feeding an infant. Small amounts of dexchlorpheniramine pass into breast milk and may cause unusual excitement or irritability in nursing infants. ---------------- The material contained here is "FOR INFORMATION ONLY" and should not replace the counsel and advice of your personal physician.
