1. Why am I using Panadol Allergy Sinus?

Panadol Allergy Sinus contains the active ingredient paracetamol, pseudoephedrine hydrochloride and chlorphenamine maleate.

Paracetamol works to stop the pain messages from getting through to the brain. It also acts in the brain to reduce fever.

Pseudoephedrine hydrochloride belongs to a group of medicines called sympathomimetic decongestants. It works by reducing congestion in the upper respiratory tract, including the nose, nasal passages and sinuses, and making it easier to breathe.

Chlorphenamine maleate belongs to a group of medicines called 'antihistamines'. Antihistamines help reduce allergic symptoms by preventing the effects of a substance called histamine. Histamine is produced by the body in response to foreign substances that the body is allergic to.

Panadol Allergy Sinus is used for the temporary relief of sinusitis symptoms, nasal congestion and allergic symptoms such as runny nose, sneezing, itchy and watery eyes.
