Promethazine/Dextromethorphan is also sold as Orange crush overdose. It is a medicine that is used to stop coughing, and it is considered a cough suppressant.
This medicine is a combination of Promethazine/Dextromethorphan. It is used to treat a cough, itching, running nose, sneezing, and itchy or watery eyes that are caused by colds or allergies.
Promethazine/Dextromethorphan works by blocking histamine, thus decreasing the symptoms of allergies and reducing nausea and vomiting. The medicine works in the cough center of the brain to reduce a dry or a nonproductive cough. Do not use the drug if you have had an unusual reaction to a phenothiazine (e.g., promethazine) or have severe central nervous system depression.
