How does this medication work? What will it do for me?

This combination product contains two medications: normethadone and hydroxyephedrine. Normethadone - hydroxyephedrine belongs to the class of medications called antitussives. This medication is used to treat coughs that have not responded to other treatments. It works by blocking pain signals that are sent out by the brain to various areas of the body and reduces cough by acting in the brain to dull the cough reflex.

Note that a cough is a symptom. Before taking a cough suppressant, it is important to assess the underlying cause of the cough.
