Key takeaways
Alka-Seltzer (citric acid/aspirin/sodium bicarbonate) and pantoprazole (Protonix) are both used to treat stomach issues, but they work differently and are used for different conditions. Alka-Seltzer is an over-the-counter combination of antacids and a nonsteroidal anti-inflammatory drug (NSAID), which helps with heartburn, indigestion, and pain relief. You dissolve it in water and drink it, and it works quickly to neutralize stomach acid. On the other hand, pantoprazole is a prescription-only proton pump inhibitor (PPI) that reduces the amount of acid your stomach makes. It's used for more serious conditions like gastroesophageal reflux disease (GERD) and erosive esophagitis and is typically taken once daily. While Alka-Seltzer can be used for immediate relief, pantoprazole takes a few days to show noticeable effects. Alka-Seltzer contains aspirin, which can cause stomach bleeding, especially in older adults or those with certain health conditions, whereas pantoprazole can cause long-term side effects like bone fractures and low magnesium levels if used for extended periods.
