Käyttöaiheet:

Promethazine hydrochloride and dextromethorphan hydrobromide syrup is indicated for the temporary relief of coughs and upper respiratory symptoms associated with allergy or the common cold. Dextromethorphan should not be used in patients receiving a monoamine oxidase inhibitor (MAOI) (see PRECAUTIONS, Drug Interactions ). Promethazine is contraindicated in comatose states, and in individuals known to be hypersensitive or to have had an idiosyncratic reaction to promethazine or to other phenothiazines. Antihistamines are contraindicated for use in the treatment of lower respiratory tract symptoms, including asthma. According to the WHO Expert Committee on Drug Dependence, dextromethorphan could produce very slight psychic dependence but no physical dependence.
