Indications for Use
Treatment of dry, nonproductive cough and chronic bronchitis.
Not FDA approved for use in animals, but it is an accepted practice to use dextromethorphan in specific cases. Available over the counter. Dextromethorphan works by suppressing the cough center in the brain. It does not cause profound sedation like the narcotic cough suppressants can. Do NOT use cough suppressants in animals that have a productive, moist cough, as the body needs to be able to rid itself of the phlegm and other secretions in the lungs. Cough suppressants are most useful in dogs with a dry, hacking cough like kennel cough or a cough secondary to a collapsing trachea. Cats with chronic bronchitis may benefit from a cough suppressant. Chronic coughing irritates the respiratory tract causing more coughing. The goal of the treatment would be to stop the coughing enough to allow the inflammation and irritation to decrease and stop the cycle.
Usual Dose and Administration
Dogs and Cats: 0.25-1 mg/pound by mouth every 8 hours.
Duration of treatment depends on reason for treatment and response to treatment.
