In a recent BMJ article, Llewelyn et al. argue that the old dogma of completing a prescribed course of antibiotics to prevent antibiotic-resistance is a myth, not based on evidence. Actually the opposite, namely taking antibiotics for longer than necessary, increases the risk of resistance.
While I love breaking down old dogmas (we actually had a poll on this topic some time back), many of today’s papers in the Netherlands (and I am pretty sure elsewhere, too) misinterpret the study, by slaughtering the message to patients to “always complete the full prescription”. One of the Netherlands most influential newspapers the Volkskrant, already wrote: “Finishing antibiotic course? Nonsense.”
