Protect patients from harm

摘要

I write to share my concerns about the potential for harm to. patients taking anticoagulants when they are prescribed or advised to buy miconazole oral gel, as raised by Sonia Baker (PJ, 15 March, p308). During my own experience of running international normalised ratio monitoring climes, I have encountered several similar instances of the potentiation of INR by miconazole oral gel. These have largely been due to GPs issuing a handwritten or acute prescription, without adequate reference to BNF interactions or to interaction prompts from their surgery computer systems.
