How Long Can You Safely Take a PPI?
Medically reviewed by Linda Girgis | MD, Girgis Family Medicine on August 22nd, 2026.
PPIs are generally considered safe for short-term use of 4-8 weeks for most conditions. For chronic conditions like GERD or Barrett's esophagus, long-term use may be necessary under medical supervision. Studies show that continuous PPI use beyond 12 months increases risks of kidney disease, bone fractures, and vitamin B12 deficiency by 10-30%. The FDA recommends limiting over-the-counter PPI use to 14 days every 4 months unless directed by a physician. Your doctor can determine the appropriate duration based on your specific condition and monitor for potential side effects during extended use.
