Alerpic

ALERPIC is the combination of an antihistamine (pheniramine maleate) and a decongestant (nafazoline hydrochloride).


Indications and uses

Alerpic is indicated in cases of eye irritation and co-management. Allergic or inflammatory eye reactions, conjunctival irritations and hyperemias of diverse origin, such as those caused by dust, smog, smoke, swimming, contact lenses, sun rays, among others.

Drug Interactions

First-generation antihistamines such as pheniramine can increase the CNS depressant effects of various other substances (for example, monoamine oxidase inhibitors, tricyclic antidepressants, alcohol, antiparkinsonians, barbiturates, tranquilizers, and narcotics). Pheniramine can also inhibit the action of anticoagulants and interact with progesterone, reserpine, and thiazide diuretics. Oral contraceptives can decrease the effectiveness of antihistamines. Concomitant use with Naproline or tricyclic antidepressants and Nafazolin may potentiate the pressor effect of Nafazolin. Patients treated with MAO inhibitors may experience severe hypertensive crisis if they receive a sympathomimetic agent.
