When administering medications, how should the body surface area be determined when doses are provided per square metre of body surface area? Where can I obtain a reference list of medications that are safe to use during pregnancy and lactation, as well as those that should be avoided? Could Kumar and Clark's Clinical Medicine's upcoming edition incorporate this? Where might I locate a table of medicine dosages for children? The use of steroids in daily life is the subject of my query. What dosages are employed in inflammatory bowel disease, and when is the dosage reduced? What is the safe dosage and duration of dexmethasone therapy to prevent negative side effects?
