How NAC Tablet works
NAC Tablet is a combination of two pain relievers (Nimesulide, Paracetamol), one antacid (Magnesium Trisilicate) and one antiallergic (Chlorpheniramine Maleate). The pain relievers work by blocking the release of certain chemical messengers that cause pain and fever. The antacid neutralizes the excess acid in the stomach and reduces side effects of the pain relievers. The antiallergic relieves allergy symptoms like runny nose, sneezing and watery eyes.
