Codeine is in a class of drugs called narcotic analgesics.
It relieves pain. Aspirin is a less potent pain reliever, as well as an anti-inflammatory and a fever reducer. Aspirin increases the effects of codeine. If you have stomach ulcers, have a bleeding or platelet disorder, or have recently had surgery, you may not be able to take this drug. Codeine is habit forming and should be used only under close supervision if you have an alcohol or drug addiction.
