Kohfit DX Syrup Sugar Free is a multi-symptom relief formulation containing Phenylephrine (5mg/5ml), Chlorpheniramine Maleate (2mg/5ml), and Dextromethorphan Hydrobromide (15mg/5ml). This combination is indicated for the symptomatic treatment of nasal congestion, allergic rhinitis, and cough associated with upper respiratory tract infections. Phenylephrine acts as a selective alpha-1 adrenergic receptor agonist, providing effective decongestion by constricting dilated blood vessels in the nasal mucosa, thereby reducing swelling and nasal obstruction. Chlorpheniramine Maleate, a first-generation antihistamine, alleviates allergic symptoms such as sneezing, runny nose, and watery eyes by blocking H1 histamine receptors. Dextromethorphan Hydrobromide serves as a centrally acting antitussive, suppressing the cough reflex through its action on the medullary cough center without causing significant sedation. The sugar-free formulation makes it suitable for diabetic patients and those requiring sugar restriction. Kohfit DX Syrup should be used as directed by a healthcare professional, with caution advised in patients with hypertension, glaucoma, or thyroid disorders due to the sympathomimetic effects of Phenylephrine. Common side effects may include dizziness, dry mouth, or mild sedation. It is contraindicated in patients hypersensitive to any of the components and should not be used concomitantly with monoamine oxidase inhibitors.
