Q: Omeprezole 20mg versus Raintidine 300mg?

My husband switched over to Raintidine 300mg from Omeprezole 20mg.  Is this mg difference okay/safe to take?  My husband is almost 60 years old.

These are two very different medications so you don't need to worry necessarily about the difference in mg. Ranitidine (trade name: Zantac) is an H2 blocker and Omeprazole (trade name: Prilosec) is a Proton Pump Inhibitor.


You can read more about these medications here:


Please note there are five pages about these meds and you will want to click through all of them.


I recently switched to Ranitidine from Omeprazole as well. One of the biggest issues I'm having is remembering to take both doses of my Ranitidine. Once a day for the Omeprazole was easier to remember. I often realize I forgot to take my morning dose of Ranitidine when my reflux starts flaring.


Best of luck - Stephanie
