What does it do?

This ingredient acts as a cough suppressant that works on the central nervous system, primarily used to alleviate dry cough. It is specialized in suppressing cough rather than providing antipyretic or analgesic effects.

Dextromethorphan acts on the cough center in the brain, reducing the cough reflex. This helps to reduce coughing, alleviating discomfort for the patient.
