Proton pump inhibitors (PPIs) are widely used medicines that relieve heartburn by reducing stomach acid production. For that purpose, they're quite effective.

“It is probably one of the most popular drugs prescribed worldwide for treatment of heartburn and gastroesophageal reflux (GERD), and it has been around since 1989,” says Rudolph A. Bedford, MD, a gastroenterologist at Digestive Health Associates in Los Angeles, California. These medicines are available over the counter, under brand names including Prilosec and Nexium.

According to Dr. Bedford, while some patients, like those who have been diagnosed with a peptic ulcer, might be on PPIs temporarily (usually for a couple of months), those who suffer from chronic heartburn could be on them for years, or even indefinitely. Unfortunately, long-term use of PPIs has been linked to several potentially dangerous conditions.
