Abstract : In recent years, the number of drug shortages has risen alarmingly both in Belgium and internationally. Between 2010 and 2020, the number of reported shortages is almost 27 times higher, according to the French Agency for the Safety of Medicines and Health Products. A recent survey conducted by the European Association of Hospital Pharmacists showed that 95 % of hospital pharmacists consider drug shortages to be a major problem. The drug classes most affected include anti-infectives, analgesics and anaesthetics. The sudden and unpredictable occurrence of drug shortages has a negative impact on the daily lives of healthcare professionals and patients. Doctors are sometimes forced to prescribe alternative treatments that are considered less effective or even less well tolerated. These alternatives make it more difficult for patients to adhere to their treatment and generate an additional risk of medication errors. There are several possible solutions to minimize these shortages: relocating production sites to Europe, imposing penalties on offending companies, adopting a common European policy for managing shortages of medicines of major therapeutic interest,... As a corollary to these proposals, legal texts have been adopted to regulate and guarantee the supply of medicines in Belgium.
