What is Promethazine VC with codeine syrup?

Promethazine VC with codeine syrup is a prescription cough syrup used to treat cough and upper respiratory symptoms such as a runny nose. It contains two medications – promethazine and codeine.

What is promethazine?

Promethazine is an antihistamine that works by blocking the effects of histamine in the body. Histamine is a natural chemical released by the immune system during an allergic reaction. By blocking histamine, promethazine helps reduce allergy symptoms such as a runny nose, watery eyes, sneezing, and itching. Promethazine also has sedative effects that can help suppress coughing.

What is codeine?

Codeine is an opioid cough suppressant that works by depressing the cough reflex in the brain. It helps control coughing by reducing the urge to cough. Codeine also has mild pain-relieving effects.

What are the uses of promethazine VC with codeine syrup?

Promethazine VC with codeine syrup is used to treat the following conditions:

  • Cough – codeine suppresses the cough reflex
  • Common cold symptoms – promethazine relieves sneezing, runny nose, watery eyes
  • Allergies – promethazine blocks histamine effects
  • Upper respiratory tract infections – the combination of promethazine and codeine relieve cough and other symptoms

This medication provides relief of multiple cold and allergy symptoms by combining the effects of an antihistamine (promethazine) with a cough suppressant (codeine).
