This combination is typically used to relieve symptoms associated with coughs and colds, including coughing, sneezing, runny nose, and watery eyes.
How does Promethazine VC with Codeine work?
The medication's dual action addresses multiple symptoms. Promethazine hydrochloride works by blocking the effects of histamine, a substance in the body that causes allergic symptoms. It also has sedative properties that can help with restlessness and sleep disturbances. Codeine phosphate acts on the brain's cough center to suppress the cough reflex and can also provide mild pain relief [1].
