Nuhist Syrup is a multi-ingredient formulation designed to provide symptomatic relief from common cold and allergic conditions. It contains Chlorpheniramine Maleate (0.5mg/5ml), an antihistamine that alleviates allergic symptoms such as sneezing, runny nose, and watery eyes by blocking histamine H1 receptors. Phenylephrine (5mg/5ml), a selective alpha-1 adrenergic receptor agonist, acts as a nasal decongestant by constricting blood vessels in the nasal mucosa, thereby reducing nasal congestion. Paracetamol (125mg/5ml) serves as an analgesic and antipyretic agent, effectively reducing fever and relieving mild to moderate pain associated with cold and flu. Sodium Citrate (60mg/5ml) functions as an expectorant and mucolytic, helping to loosen mucus and facilitate its clearance from the respiratory tract. Nuhist Syrup is indicated for the management of symptoms related to upper respiratory tract infections, allergic rhinitis, and sinusitis. It is suitable for use in pediatric and adult patients as directed by a healthcare professional. Caution is advised in patients with hypertension, cardiovascular disorders, or hypersensitivity to any component. The syrup should be used under medical supervision, adhering strictly to recommended dosages to minimize potential side effects and drug interactions.
