Codeine and Codeinae Sulphas. Hypnotic, analgesic, sedative. Not used in case of severe pain. Greatest use in irritating coughs, where it has been very unwisely displaced by heroin by many physicians. Also used in ovarian pains, vesical affections, and in diabetes mellitus. Dose of either codeine or its sulphate, 1/2 to 2 gr., or less if for continuous administration. Never give to young children. It is a very valuable agent in small doses. See Heroin.
