Primary Uses at a Glance

Relief of Dry, Unproductive Cough

Cosylan Syrup is used for dry, non-productive cough — a cough that does not produce mucus. This is the primary indication for antitussive cough suppressants. Ethylmorphine hydrochloride reduces the activity of the cough reflex in the central nervous system, providing relief from persistent irritating cough.

As directed by your doctor or pharmacist.

Symptomatic Treatment of Irritating Cough in Upper Respiratory Infections

Cosylan Syrup is used for the symptomatic relief of cough associated with upper respiratory tract infections such as the common cold. It does not treat the infection itself but relieves the discomfort of persistent coughing.

As directed by your doctor or pharmacist. Not for use in productive (chesty) cough.

Throat and Airway Soothing in Bronchitis

Cosylan Syrup is used for the symptomatic relief of dry cough in bronchitis — inflammation of the airways. The menthol component provides a soothing effect on the throat and upper airways. This is used as supportive symptomatic treatment only.

As directed by your doctor or pharmacist.

Dry, irritating cough due to postnasal drip
