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.
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
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.
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:
