New Delhi, May 23 -- The Union health ministry on Friday brought the widely prescribed drug Pregabalin under the Schedule H1 of the Drugs Rules, 1945. Pregabalin is commonly prescribed for chronic pain, neuropathies, fibromyalgia and certain neurological conditions. It was earlier regulated under Schedule H. A gazette notification by the ministry said that under the revised classification, the drug can only be sold only after a prescription by a registered medical practitioner. Retail chemists will be required to maintain a separate register recording details of prescriptions and sales of drug. The ministry also directed manufacturers to prominently display the mandatory "Schedule H1 Drug Warning" label on product packaging. It said violations and non-compliance would attract penal action under the Drugs and Cosmetics Act, 1940, and related rules. htc...
