Hatric 2 Oral Drops is a combination medication containing Chlorpheniramine Maleate (1 mg/ml) and Phenylephrine (2.5 mg/ml), formulated for the symptomatic relief of allergic conditions and nasal congestion. Chlorpheniramine Maleate is an antihistamine that effectively blocks H1 histamine receptors, thereby alleviating symptoms such as sneezing, itching, watery eyes, and runny nose associated with allergic rhinitis, hay fever, and other hypersensitivity reactions. Phenylephrine acts as a selective alpha-1 adrenergic receptor agonist, producing vasoconstriction of nasal mucosal blood vessels, which reduces swelling and nasal congestion. This dual-action formulation is particularly beneficial in managing upper respiratory tract allergies accompanied by nasal obstruction. Hatric 2 Oral Drops is indicated for use in adults and children above the age of two years, with dosage and duration of therapy tailored according to clinical response and patient age. Caution is advised in patients with hypertension, cardiovascular disorders, hyperthyroidism, and glaucoma due to the sympathomimetic effects of phenylephrine. Common adverse effects may include dizziness, dry mouth, and mild gastrointestinal disturbances. It is recommended to consult a healthcare professional before use, especially in pregnant or lactating women, to ensure safe and appropriate therapy.
