Firstly apologies for the length of this.
I was put on Lansoprazole 30mg capsules over 2 years ago by a GP for chest pain after food. After no improvement I asked to be referred to a gastroenterologist who, after many tests, diagnosed Achalasia as the problem. But I was never told to stop taking the Lansoprazole.
The Achalasia was very mild to begin with but is now rapidly deteriorating and I do need surgery. The problem with Lansoprazole is this: if I miss even one capsule I get agonising stomach pains, like I have swallowed nitric acid. The stomach feels on fire; although generalised in the stomach area, it feels like individual stomach cells are burning. I have to quickly take capsules again and it can take many days for things to settle down. When I first mentioned this to the gastroenterologist he said it was nothing to do with the Lansoprazole. I do know people who can just stop taking the capsules and get no effects or just mild discomfort which goes away. I deliberately missed a capsule a few weeks later and exactly the same thing happened and I went straight back to the capsules. Gastroscopy eight weeks later showed ‘just’ mild erythematous gastritis.
When I have surgery (Heller myotomy) I will not be able to take capsules or tablets for 2 to 4 weeks. In anticipation I tried orodispersible on the tongue, but I have a large osteophyte at c3/c4 which the rather sticky dissolving particles stick to and cause serious throat inflammation. The GP said just put the tablet in water and swallow. I tried this but the severe stomach pain occurred in the night and continued. So back to the capsules.
I spoke to the surgical registrar as I couldn’t go ahead with the operation until this issue was sorted, he said he didn’t know, he wasn’t a pharmacologist, but I had to somehow find my way out of this.
I asked the local pharmacist who said capsules are slow release, they don’t start acting until into the intestines and presumably more gradual than throwing liquid Lansoprazole into the stomach. She said ask my GP. He said ask the pharmacist!
No-one seems to know what to do. Doctors in particular just don’t seem to understand what these PPIs are actually doing.
Thank you for reading this far. I have a couple of urgent questions:
1). Any suggestions as to what I can do?
2). Can this agonising pain actually indicate permanent damage to the stomach lining ? The docs say no. But if I let it continue (which is not a happy prospect)?
3). Acid rebound seems to be the case here, but why do many not get this? I wonder if my extremely tight lower oesophageal sphincter is ‘trapping’ the acid - I don’t get reflux.
Any help appreciated, and sorry for going on at length.
