Hatric 3 Suspension is a combination pharmaceutical formulation containing Paracetamol 125mg, Pseudoephedrine 15mg, and Chlorpheniramine Maleate 1mg per dose, designed to provide symptomatic relief in upper respiratory tract infections. Paracetamol acts as an analgesic and antipyretic, effectively reducing fever and alleviating mild to moderate pain. Pseudoephedrine serves as a nasal decongestant by constricting dilated blood vessels in the nasal mucosa, thereby reducing nasal congestion and improving airflow. Chlorpheniramine Maleate, an antihistamine, mitigates allergic symptoms such as sneezing, runny nose, and watery eyes by blocking histamine H1 receptors. This combination is particularly useful in managing symptoms associated with common cold, allergic rhinitis, sinusitis, and other respiratory conditions characterized by nasal congestion, headache, fever, and allergic manifestations. Hatric 3 Suspension should be used according to the prescribed dosage and duration to minimize potential adverse effects, including drowsiness, dry mouth, or cardiovascular stimulation. It is contraindicated in patients with hypersensitivity to any component, severe hypertension, or concurrent use of monoamine oxidase inhibitors. Caution is advised in patients with cardiovascular disorders, glaucoma, or hyperthyroidism. Consultation with a healthcare professional is recommended prior to use to ensure safety and appropriateness of therapy.
