Iffcold Plus Oral Suspension is a combination medication containing Chlorpheniramine Maleate (2mg), Paracetamol (250mg), and Phenylephrine (5mg) per dose, formulated for the symptomatic relief of common cold and flu symptoms. Chlorpheniramine Maleate is an antihistamine that alleviates allergic manifestations 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 including headaches and body aches associated with upper respiratory tract infections. Phenylephrine is a selective alpha-1 adrenergic receptor agonist that provides nasal decongestion by constricting dilated blood vessels in the nasal mucosa, thereby improving airflow and reducing nasal congestion. Iffcold Plus Oral Suspension is indicated for adults and children above a certain age as per prescribing information, to manage symptoms of cold and flu such as nasal congestion, fever, headache, and allergic rhinitis. The suspension should be administered according to the recommended dosage to avoid potential side effects such as drowsiness from chlorpheniramine, hepatotoxicity from excessive paracetamol, or cardiovascular effects from phenylephrine. Patients with hypertension, liver impairment, or hypersensitivity to any component should consult a healthcare professional prior to use.
