is a narcotic pain-reliever and cough suppressant similar to morphine and
hydrocodone. Codeine increases tolerance to
pain, decreasing discomfort, but the pain still is apparent to the patient. In
addition to reducing pain, codeine also causes sedation drowsiness and
is habit forming (addictive). Mental and physical dependence can occur but are
unlikely when used for short-term pain relief.
Using codeine during pregnancy can cause opioid withdrawal syndrome in
the newborn, which may be life-threatening if not treated.
