OK, so at what age is someone considered elderly? In the newspaper, many people of various ages are described that way. This question came from a different reader on the same wavelength.
Common side effects of Prilosec and Zantac that are similar include diarrhea, headache, nausea, and vomiting. Side effects of Prilosec that are different from Zantac include rash and dizziness. Side effects of Zantac that are different from Prilosec include constipation, fatigue, and insomnia.
I think Prilosec can cause such problems-I see it is actually omeprazole, which I also took until I stopped it. I researched all the side effects .. suggest you do the same-just google Prilosec or omeprazole side effects, and you will be surprised.
