Can lightheadedness and breathing difficulty be the side effects of Prilosec?
Patient: Hello, I have been on prescription Prilosec for a few days to combat reflux. Today I noticed some light headedness and difficulty breathing (getting a deep breath). Could these be side effects of the drug or what s happening with my stomach acid? Thank you. Doctor: Hello,  Even without lung problems, GERD (reflux) can cause shortness of breath and difficulty breathing. Treatment can be a double-edged sword. GERD medcines like PPIs can actually increase pneumonia risk, according to several studies and very rarely light-headedness. You should take an appointment with your doctor to evaluate your health condition.  Hope I have answered your query. Let me know if I can assist you further.
