    What is Codeine?

    Codeine is a painkilling medication. Its primary purpose is for the management and treatment of pain, for instance, injuries from an operation or surgery. It is used when regular painkillers as aspirin, paracetamol, and ibuprofen are not working. It is also utilised for the treatment of diarrhoea and persistent cough.

    It is a prescription only medication. It comes in tablet, liquid, and injection or intravenous form. Often, injections are administered only in a medical facility like hospitals.

    Health benefits of Codeine

    Pain can be debilitating. It delays work, disrupts regular life, prevents one from studying, and hinders one from performing whatever a regular person would do in his or her productive state. This medicine is beneficial for patients suffering from pain where regular painkillers as aspirins, analgesics, and ibuprofens are not working.
