Pubdate: Mon, 06 Apr 1998 Source: Telegraph, The (UK) Contact: Celia Hall, Medical Editor SALES OF INSULIN TO BE RESTRICTED INSULIN, the hormone used by thousands of diabetics but increasingly abused by body builders in the false belief that it helps them enlarge their muscles, is to be made a prescription-only drug. To the surprise of many, including doctors, pharmacists can sell insulin legally without prescription. Now the Department of Health has decided to close the loophole after a 21-year-old amateur body builder suffered brain damage last year from injecting excessive amounts of insulin. Following recommendations from the the Committee on Safety of Medicines, the department said that from August insulin would be available only on prescription unless a pharmacist was faced with an emergency. "The new regulation is partly because of the recognition that athletes are abusing it," a health department spokesman said yesterday. "In fact, pharmacy-only medicines can be given by a pharmacist in emergencies but this rarely happens." A year ago doctors at Hemel Hempstead Hospital, Herts, called for a review of prescribing after treating the body builder. Two junior doctors bought soluble insulin easily over the counter from a chemist without any identification. They found that the body-building magazines and sites on the Internet were promoting it widely. However, in a healthy body, too much insulin will deprive the brain of glucose, leading to neurological damage. There is no evidence that it builds muscle. The British Diabetic Association, which represents 1.4 million people with diabetes, is advising diabetics to carry identification with them for emergencies. A spokesman said: "Unfortunately if people want to abuse any drug, they can always find a supply."
