France has just followed USA in recalling Ranitidine and Zantac. Apparently the FDA have found that the generic contains an impurity that has carcinogenic properties. (Note this impurity is found in many foodstuffs, but that doesn’t seem to bother them). Greece, Cyprus and Ireland have done so too. But not the UK as yet.
Anyway, be aware that your prescription may not get filled. I was sent away with omeprazole which I hate as much higher risk!
