The possibility of rebound acid reflux is very low when one tries to stop omeprazone however rarely it can happen so you are doing the right thing of taking precautions I see that she did have rebound acid reflux issue before so your concern is genuine and appropriate so we need to address this issue earnestly
I had asked a question earlier regarding how was she tapered off earlier, I am asking this because she seems to have had issues with rebound acid reflux before, so I am curious to find out what method you guys attempted, so that we do not repeat it again, and risk rebound acid reflux again. What I will do is provide an initial answer to your question, if you guys tried similar approach before please let me know, I will provide you guys with alternate approaches.
This is one of the common ways of accomplishing this task of coming off Omeprazole and preventing the development of acid reflux;
I see that she is on 20 mg capsule preparation. It will be easier to taper off with a tablet preparation, so first she can switch to 20 mg tablet preparation
She can reduce the dose by 5 mg (one fourth or 1/4th of the 20 mg tablet = 5mg) once in every about week or so
So from the current 20 mg per day initially she will reduce to;
15 mg and stay on it for about a week,
Then on 10 mg x a week
5 mg x a week
And then to stop
So she will be coming off this medication over a period of about 3 weeks or so and this is very gradual tapering off and this should prevent the possibility of any rebound acid reflux developing in her.
The above approach should work out, if this does not work out then another effective approach is to institute treatment with H2 blocker acid secretion reducing agents like Famotidine or Ranitidine for some time (say for a week or two) and when symptoms resolve then the H2 blocker can be stopped without any rebound issues.
If you guys have already tried similar approaches please let me know, we can try some other methods to help her from developing rebound acid reflux issues while coming off Omeprazole.
