Lansoprazole

It's unlikely you'll get side effects on 45 mg. You usually need a high dose for years.

I was on omeprazole for 15 years. 20mg omeprazole is equivalent to 30 mg lansoprazole.

It was only the latter years when my dose was increased to 80mg (ie equivalent to 120mg lansoprazole) that I started getting the "side effects". They are caused by the induced hypochlorhydria inhibiting the absorption of essential minerals. For me, I became anaemic.

If you visit the www DownWithAcid org uk book / website, you'll find a chapter on "Induced Hypochlorhydria" in the "Combinations and Complications section".

I was prescribed Lanzoprazole 7 years ago when first diagnosed with acid reflux. I had no signs of Barretts at that time but was treated symptomatic ally. After 6 years the acid reflux returned with a vengeance. I had an endoscopy which showed that I had Barretts and a sliding hiatus hernia. So my personal experience has shown me that for me and I emphasise purely from my own experience, that Lanzoprazole has only masked my symptoms  over these past years. I manage my symptoms now with diet, I've cut out most dairy products. Having coconut milk, goats cheese and gluten free bread and pasta. Also a glass coconut water is marvellous for excess acid. Occasionally I will have a cuppa with skimmed milk and the odd bacon sandwich but hey, life is too short to deny yourself sometimes. On those occasions I have a sip of double action gaviscon. I think personally that one has to make the decision whether to continue with taking medication, that might work, or in my case mask the underlining problem. I think everyone manages this differently and have to individually find the best way forward. I wish you all the very best in finding your way forward.
