Codeine sulfate is an opioid analgesic that is typically used to treat pain, cough and sometimes to suppress premature labor.

In some patients, Codeine is less effective as an analgesic while in others it can provide highly effective analgesic effects. This is largely dependent on the method in which each individual metabolizes codeine.
