Drug Interactions

MAO inhibitors prolong and intensify the anticholinergic (drying) effects of antihistamines.

WarningS

Antihistamines should be used with considerable caution in patients with:

• Narrow angle glaucoma

Stenosing peptic ulcer

Pyloroduodenal obstruction

Symptomatic prostatic hypertrophy

Bladder neck obstruction

Use In Children

In infants and children, especially, antihistamines in overdosage may cause hallucinations, convulsions, or death.

As in adults, antihistamines may diminish mental alertness in children. In the young child, particularly, they may produce excitation.

Use In Pregnancy

Experience with this drug in pregnant women is inadequate to determine whether there exists a potential for harm to the developing fetus.

Use With CNS Depressants

POLMON Oral Solution has additive effects with alcohol and other CNS depressants (hypnotics, sedatives, tranquilizers, etc.).

Use In Activities Requiring Mental Alertness

Patients should be warned about engaging in activities requiring mental alertness such as driving a car or operating appliances, machinery, etc.

Use In The Elderly (approximately 60 years or older)

Antihistamines are more likely to cause dizziness, sedation, and hypotension in elderly patients.

Precautions

POLMON Oral Solution has an atropine-like action and, therefore, should be used with caution in patients with:

History of bronchial asthma
Increased intraocular pressure
Hyperthyroidism
Cardiovascular disease
Hypertension

Overdose

Antihistamine overdosage reactions may vary from central nervous system depression to stimulation. Stimulation is particularly likely in children. Atropine-like signs and symptoms—dry mouth, fixed, dilated pupils, flushing, and gastrointestinal symptoms may also occur.

If vomiting has not occurred spontaneously the patient should be induced to vomit. This is best done by having the patient drink a glass of water or milk after which the patient should be made to gag. Precautions against aspiration must be taken, especially in infants and children.

Saline cathartics, such as milk of magnesia, draw water into the bowel by osmosis and therefore, are valuable for their action in rapid dilution of bowel content.

Stimulants should not be used.

Vasopressors may be used to treat hypotension.

Contraindications

Use In Newborn Or Premature Infants

This drug should not be used in newborn or premature infants.

Use In Nursing Mothers

Because of the higher risk of antihistamines for infants generally and for newborns and prematures in particular, antihistamine therapy is contraindicated in nursing mothers.

Use In Lower Respiratory Disease

Antihistamines should NOT be used to treat lower respiratory tract symptoms including asthma.

Antihistamines are also contraindicated in the following conditions:

• Hypersensitivity to dexchlorpheniramine maleate or other antihistamines of similar chemical structure Monoamine oxidase inhibitor therapy (See DRUG INTERACTION section)

Dexchlorpheniramine maleate is an antihistamine with anticholinergic (drying) and sedative side effects. Antihistamines appear to compete with histamine for cell receptor sites on effector cells.
