Hayrest-Plus Oral Suspension Orange is a combination medication formulated to provide symptomatic relief from common cold and allergic conditions. Each 5 ml of the suspension contains Chlorpheniramine Maleate 2 mg, Paracetamol 250 mg, and Phenylephrine 5 mg. Chlorpheniramine Maleate is an antihistamine that alleviates allergic symptoms such as sneezing, runny nose, and watery eyes by blocking histamine H1 receptors. Paracetamol acts as an analgesic and antipyretic, effectively reducing fever and relieving mild to moderate pain associated with cold and flu. Phenylephrine is a selective alpha-1 adrenergic receptor agonist that serves as a nasal decongestant by constricting dilated blood vessels in the nasal mucosa, thereby reducing nasal congestion and improving airflow. Hayrest-Plus Oral Suspension is indicated for the temporary relief of symptoms related to allergic rhinitis, common cold, sinusitis, and other upper respiratory tract infections. It is suitable for pediatric use under appropriate dosing guidelines. Caution is advised in patients with hypertension, cardiovascular disorders, or hypersensitivity to any component. The orange-flavored suspension ensures palatability and ease of administration. Always use under medical supervision, adhering to recommended dosages to avoid potential adverse effects or drug interactions.
