Last year on holiday I developed solar angioedema for the first time ever and my top lip swelled up hugely. This year I'd like to avoid the same thing happening - can any angioedema sufferers recommend an antihistamine. I asked in my local Boots and was told by a general member of staff (not pharmacist) that 'they're all good', but surely some are for rhinitis, others better at treating rashes etc?
Any suggestions gratefully received.
