Rexcof DX Cough Syrup contains two main active ingredients: chlorpheniramine and dextromethorphan.
- Chlorpheniramine works by blocking histamine, a natural substance that causes allergic reactions. It also blocks acetylcholine, another natural substance that helps dry up body fluids.
- Dextromethorphan acts as a cough suppressant by reducing the urge to cough.
These active ingredients work together to provide relief from dry cough and allergic symptoms such as runny nose, watery eyes, sneezing, and throat irritation. Chlorpheniramine blocks histamine to alleviate these allergic reactions, while dextromethorphan reduces the activity of the cough centre in the brain to help manage dry cough.
