What Is Panadol Allergy Sinus Used For?
Panadol Allergy Sinus is a combination medication that contains three active ingredients working together to provide relief from multiple symptoms.
Primary Uses
This medication is used for the temporary relief of sinusitis symptoms, nasal congestion, and allergic symptoms such as runny nose, sneezing, itchy and watery eyes.
How It Works
Paracetamol stops pain messages from reaching the brain and reduces fever. Pseudoephedrine hydrochloride reduces congestion in the upper respiratory tract, nose, nasal passages and sinuses, making breathing easier. Chlorphenamine maleate is an antihistamine that reduces allergic symptoms by preventing the effects of histamine, which the body produces in response to allergens.
How to Take Panadol Allergy Sinus
Always follow the directions carefully and use the smallest dose needed to treat your symptoms for the shortest time necessary.
Dosage Instructions
Adults and children 12 years and over: Take 2 tablets every 6 hours as necessary. Do not take more than 8 tablets in 24 hours. Do not take more frequently than every 6 hours. Swallow with water or other fluid. Do not use in children under 12 years. Adults should only take for a few days at a time unless your doctor tells you otherwise. Children 12-17 years should only be given this medication for up to 48 hours unless a doctor advises longer use.
Never Exceed Dose: Do not take more than the recommended dose as it may cause serious harm to your liver.
