The antibiotic amoxicillin is usually recommended as a first-line treatment for many common infections affecting children. Repeated lockdowns related to the coronavirus disease 2019 pandemic have contributed to supply difficulties for many drugs, including antibiotics. However, the risks associated with amoxicillin supply shortages appear not to have been sufficiently assessed, and the crisis we are facing today is serious and particularly dangerous for children’s health. Without rigorous measures to prevent shortages related to drug production and distribution, populations could face a post-antibiotic era in which common infections and minor injuries can result in serious life-threatening situations. The availability of medicines declared by WHO as essential should be guaranteed not only in production but also in fair distribution. And this principle must be ensured by national and international regulatory agencies.
