Pholcodine is a drug which is an opioid cough suppressant (antitussive). It helps suppress unproductive coughs and also has a mild sedative effect, but has little or no analgesic effects. It is also known as morpholinylethylmorphine and homocodeine.

Pholcodine is found in certain cough lozenges. However, in the UK, the preparation is almost exclusively an oral solution, typically 5 mg / 5 ml. Adult dosage is 5-10ml up to 3-4 times daily. Pholcodine now largely replaces the previously more common codeine linctus, as it has a much lower potential for dependence.
