WARNINGS :

Use with caution in patients with hypertension, cardiovascular disease, hyperthyroidism, diabetes, narrow angle glaucoma or prostatic hypertrophy. Use with caution or avoid use in patients taking monoamine oxidase (MAO) inhibitors. This product contains antihistamines which may cause drowsiness and may have additive central nervous system (CNS) effects with alcohol or other CNS depressants (e.g., hypnotics, sedatives, tranquilizers).

PRECAUTIONS :

General

Antihistamines are more likely to cause dizziness, sedation and hypotension in elderly patients. Antihistamines may cause excitation, particularly in children, but their combination with sympathomimetics may cause either mild stimulation or mild sedation.

Information for the Patient

Caution patients against drinking alcoholic beverages or engaging in potentially hazardous activities requiring alertness, such as driving a car or operating machinery, while using this product.

Carcinogenesis, Mutagenesis, and Impairment of Fertility

No long term animal studies have been performed with this combination drug.

Pregnancy, Teratogenic Effects, Pregnancy Category C

Animal reproduction studies have not been conducted with this combination drug. It is also now known whether this combination drug can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. This combination drug should be given to a pregnant woman only if clearly needed.

Nursing Mothers

This combination drug should not be administered to a nursing woman.

DRUG INTERACTIONS :

MAO inhibitors may prolong and intensify the anticholinergic effects of antihistamines and the overall effects of sympathomimetic agents.

ADVERSE REACTIONS :

Adverse effects associated with this combination drug at recommended doses have been minimal. The most common have been drowsiness, sedation, dryness of mucous membranes and gastrointestinal effects. Serious side effects with oral antihistamines or sympathomimetics have been rare.

OVERDOSAGE :

Signs and Symptoms

May vary from CNS depression to stimulation (restlessness to convulsions). Antihistamine overdosage in young children may lead to convulsions and death. Atropine-like signs and symptoms may be prominent.

Treatment

Induce vomiting if it has not occurred spontaneously. Precautions must be taken against aspiration especially in infants, children and comatose patients. If gastric lavage is indicated, isotonic or half-isotonic saline solution is preferred. Stimulants should not be used. If hypotension is a problem, vasopressor agents may be considered.
