Koffset DX Syrup Sugar Free is a multi-ingredient pharmaceutical formulation designed for the symptomatic relief of cough and nasal congestion associated with upper respiratory tract infections and allergic conditions. Each 5 ml dose contains Phenylephrine 5 mg, a selective alpha-1 adrenergic receptor agonist that acts as a decongestant by constricting dilated blood vessels in the nasal mucosa, thereby reducing swelling and nasal congestion. Chlorpheniramine Maleate 2 mg, an antihistamine with anticholinergic properties, alleviates allergic symptoms such as rhinorrhea, sneezing, and itching by blocking H1 histamine receptors. Dextromethorphan Hydrobromide 10 mg serves as a centrally acting antitussive agent that suppresses the cough reflex by acting on the medullary cough center without causing significant sedation or respiratory depression. The sugar-free formulation makes it suitable for diabetic patients or those requiring sugar restriction. Koffset DX Syrup Sugar Free should be used according to the prescribed dosage to minimize potential side effects such as dizziness, dry mouth, or increased blood pressure. It is contraindicated in patients with hypersensitivity to any component, hypertension, or concurrent use of monoamine oxidase inhibitors. Consultation with a healthcare professional is advised prior to use, especially in pediatric, pregnant, or lactating patients.
