Codeine phosphate is available in strengths of 30 and 60mg tablets. Usual adult doses are15 to 60 mg every 4 to 6 hours (usual adult dose, 30 mg), while dosage for children (1 year and older) is weight-based (0.5mg/Kg) every 4 to 6 hours. Codeine sulfate may be expected to have additive effects when used in conjunction with alcohol, other opioids, or illicit drugs that cause central nervous system depression. There are no adequate and well-controlled studies in pregnant women. Codeine should be used during pregnancy only if the potential benefit justifies the potential risk. Codeine is secreted into human milk so benefits should outweigh risks to the breastfeeding infant. Codeine phosphate has been used in pediatric patients aged one year and above.
