I have been put on amoxicillin,
biaxin and prilosec for suspected h.pylori. I have had a hard time taking a lot of meds, including PPI's and H2 blockers. I recently stopped Pepcid due to dizziness and hallucinations, and found that it had also been the cause of unexplained itching and right leg pain (all subsided when I stopped the med). I have had chest pain on Nexium and zantac. Now that I am on the Prilosec, I am having shortness of breath, chest tightness, dizziness, and malaise.
