A new study published in The Lancet Public Health journal reveals that almost all countries are overusing 'watch' class antibiotics, which are stronger drugs meant for specific conditions and contribute significantly to antibiotic resistance. The research developed a framework to assess appropriate antibiotic use and found that while many countries overuse antibiotics, particularly the 'watch' category, some also underuse 'reserve' antibiotics, potentially leaving patients with drug-resistant infections untreated. The study highlights a global inequality where lower-income countries need more specialised antibiotics but higher-income countries use them more.
