Codeine 10mg is a prescription medication that belongs to a class of drugs known as opioid analgesics, which are used to treat pain. It is a milder opioid than some other commonly used ones, such as morphine and oxycodone, and is often used in combination with other medications to treat coughs and diarrhea.

Codeine 10mg works by binding to opioid receptors in the brain and spinal cord, which reduces the perception of pain and increases the feeling of relaxation. It is typically taken orally, either as a tablet or a liquid solution, and the effects can last for several hours.
