Codeine
Codeine is a common painkiller that belongs to a group of medications called opiates. Doctors often prescribe it to treat pain after an injury or surgical operation. The medication is suitable for more serious cases of persistent pain when other common painkillers, such as aspirin, ibuprofen, or paracetamol, are not effective. Codeine works by blocking pain signals in the brain and central nervous system to other parts of the body, which subsequently helps alleviate stress and anxiety caused by pain. Many people also take codeine to treat diarrhea. It is available in the liquid or tablet form. An injective can also be done only in a hospital. Due to its availability, many people often abuse it to reduce pain. [8]
