Codeine phosphate is an opioid analgesic used to treat mild to moderate pain. It may also be used to treat other conditions as determined by your doctor. Codeine works in the brain to change how your body feels and responds to pain.
Take this medication by mouth, usually every 4 hours as needed for pain. The dosage is based on your medical condition and response to treatment. Do not increase your dose or take this drug more often than prescribed without your doctor’s approval. Properly stop the medication when so directed.
