What Codeine Is

Codeine belongs to a class of pain medications called opiates. It alters the way the brain perceives and processes the pain signals. That way, it helps to relieve mild to moderately severe pain. Because it works in the brain, it may cause addiction even when it used properly. A doctor may prescribe it to treat a type of a cough that does not produce phlegm.
Currently, one can get some products that contain Codeine mixed with Acetaminophen or Aspirin like over-the-counter cough syrups.
