Duopharma Chloramine 4mg Tablet

Duopharma Chloramine 4mg Tablet is an antihistamine tablet containing Chlorpheniramine Maleate 4mg, used to relieve symptoms of allergic conditions such as runny nose, sneezing, itchy or watery eyes, itchy skin, hives (urticaria), and other allergy-related discomfort. Chlorpheniramine Maleate works by blocking histamine, a substance the body releases during an allergic reaction, thereby reducing the typical signs and symptoms of allergies.

This tablet is a non-prescription (over-the-counter) medicine widely used by adults and older children for allergic rhinitis, hay fever, common allergy symptoms associated with colds, and mild allergic skin reactions. Because it belongs to an older generation of antihistamines, it commonly causes drowsiness, so caution is needed when driving, operating machinery, or performing tasks that require alertness after taking it.

Chlorpheniramine Maleate is a first-generation antihistamine that works by blocking H1-histamine receptors throughout the body. When an allergen triggers an allergic response, histamine is released and binds to these receptors, causing symptoms such as sneezing, itching, and a runny nose. By blocking these receptors, Chlorpheniramine Maleate prevents histamine from producing these effects, providing relief from allergy symptoms; it also has sedating and mild anticholinergic properties, which is why drowsiness is a common effect of this tablet.

Take Duopharma Chloramine 4mg Tablet orally with a glass of water, with or without food, as directed on the product label or by a doctor or pharmacist. Swallow the tablet whole; do not crush or chew unless advised otherwise. Follow the recommended dosing schedule and do not exceed the maximum daily dose stated on the packaging.

The usual adult dose of Duopharma Chloramine 4mg Tablet is one tablet (4mg) every 4 to 6 hours as needed for allergy symptoms, not exceeding the maximum daily dose stated on the product packaging. Dosing in children and the elderly may differ and should follow the specific guidance on the label or advice from a healthcare professional.
