Codeine is an opioid -gesic to treat pain. It is generally useful in managing mild to acute degrees of pain. It can give more significant benefits in the combination of acetaminophen or ibuprofen and other nonsteroidal anti-inflammatory medicine. No pieces of evidence support the use of codeine for cough suppression in children and adults. It is an oral medication that typically starts working in about half an hour and reaches its peak effects in 1.5-2 hours.
