Key takeaways
Zegerid (omeprazole/sodium bicarbonate) and pantoprazole (Protonix) are both medications used to treat conditions related to excess stomach acid, but they have some key differences. Zegerid is a combination of a proton pump inhibitor (PPI) and an antacid, while pantoprazole is solely a PPI. Zegerid is available both over-the-counter and by prescription, whereas pantoprazole requires a prescription. Zegerid comes in capsule and liquid forms, and its sodium bicarbonate component helps protect omeprazole from stomach acid. Pantoprazole is available as tablets, a liquid, and even as an intravenous (IV) injection. Zegerid must be taken on an empty stomach, while pantoprazole tablets can be taken with or without food. Both medications can cause side effects like headaches and diarrhea, but Zegerid has additional risks due to its sodium content, which can be problematic for those on a low-sodium diet.
