etafedrine - doxylamine - hydrocodone
How does this medication work? What will it do for me?
This medication contains 3 active ingredients: etafedrine, doxylamine, and hydrocodone. It helps to control cough associated with inflammation of the mouth and throat that is not helped by cough medications that are less strong.
Hydrocodone is a narcotic medication that is an antitussive (cough suppressant). It helps to reduce cough by affecting the cough centre in the brain. Etafedrine belongs to the family of medications called decongestants. It works by narrowing blood vessels in the nasal passages, helping to relieve nasal stuffiness. Doxylamine belongs to the family of medications called antihistamines. It works by drying up the excess fluid that causes a runny nose and watery eyes.
