Re: Dosing of Prilosec vs. Prevacid
It's tough to say for sure, and it's possible that it actually varies from person to person depending on exactly how you metabolize stuff.
For myself, I find that 30 mg of Prevacid is stronger than 20 mg of Prilosec. I never tried to directly compare the 15 mg.
You could try the 15mg, and if it's not enough, add another one.
