Hospital started me off on omeprazole & then after 2 weeks changed it to Lansoprazole, but again it was stopped after 6 weeks as my surgeon and dietician both said it wasn't necessary if I wasn't getting any acid reflux, and the long term side effects included liver problems and also gastric problems, and when I researched this on the internet, they are now linking long term use of these acid inhibitors with various stomach cancers etc., In America, doctors are not allowed to prescribe the drug for more than a 2 year period and then only if the patient has ulcers or a serious stomach condition. But in truth I suppose it is better to do without any drug if you possibly can. Must admit I don't miss the Lansoprazole and haven't had any reflux since not taking them...
