Just to make sure:
if you take Omeprazole (PPI) AND Ranitidine (H2 Blocker),
you need to make sure to take them not together at same time.
PPI need a ph of 4.5 and lower, so if you cut the acid down with H2blocker (effect lasts about 12 hours), the taken PPI is useless, not used, doesn't get converted into useful metabolite, you actually don't cut your acid down as prescribed.
e.g. take PPI in the very morning,
H2 in the early evening or other way round.
Space them 12 hours apart if you are adviced to take both.
Maybe you do that anyway.
Just to make sure. You don't get the best PPI effect otherwise.
Maybe you could only take PPI? (and no antacids please, same trouble if taken together at that time, antacids at least do not last as long, so a 4 or 8 hour space is enough, depending when your stomach has emptied the antacid out)
And yes,
coming off is a very, very slow process, over months!
Our gastro doc stopped my daughter cold turkey from PPI, I even shook my head and said 'what?', oh, it's only 2x20mg Esomeprazole (Nexium) she is on. .... No wonder within 3 days she was in sour agony.
Had to go back on PPI asap, and gave every second day half the amount for 2 weeks, then 2 weeks half the amount, asked for the lowest dose or one, that had the split line to be able to cut tablet (otherwise never ever cut PPI, they are coated) and continued another 2 weeks. Then the smallest PPI combined with H2blocker on the other half of day, now on H2blockers only, but twice a day and these will be eased out the same week long process, that covers months in the end.
Never ever stop them quickly and stopping within a week is also quickly.
But for now you need to take them
and find a reason (atrophic? gastritis at your age) and eat as paul so well recommended.
Gastritis is very tricky, takes time, but full with hope to get better.
Best of luck!
