Two cases are reported in which administration of ritodrine hydrochloride, a β-2-sympathomimetic agent, was followed by diabetic ketoacidosis when it was used for inhibition of premature labor in insulin-requiring diabetic patients. Ketoacidosis occurred shortly after intravenous ritodrine, despite previous administration of large subcutaneous doses of insulin. Early recognition and treatment of this serious complication are critical for fetal survival.
