Codeine is an opioid pain medication. An opioid is sometimes called a narcotic.

How should I take codeine?

Follow all directions on your prescription label. Codeine can slow or stop your breathing. Never use codeine in larger amounts, or for longer than prescribed. Tell your doctor if the medicine seems to stop working as well in relieving your pain.

Codeine may be habit-forming, even at regular doses. Never share this medicine with another person, especially someone with a history of drug abuse or addiction. MISUSE OF NARCOTIC MEDICINE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH, especially in a child or other person using the medicine without a prescription.

Take codeine with food or milk if it upsets your stomach.

Measure liquid medicine with a special dose-measuring spoon or medicine cup. If you do not have a dose-measuring device, ask your pharmacist for one.

Drink 6 to 8 full glasses of water daily to help prevent constipation while you are taking codeine. Do not use a stool softener (laxative) without first asking your doctor.
