Pantoprazole tablets are a proton pump inhibitor (PPI) that lowers stomach acid. They’re used for conditions caused by excess acid, such as GERD, erosive esophagitis, stomach ulcers, and Zollinger-Ellison syndrome. Brand name is Protonix; generic pantoprazole is also available. Forms include:
- Delayed-release tablets (usually 20 mg and 40 mg)
- Oral suspension
- IV form (for hospital use)
How they’re typically used
- Dosing depends on the condition and patient, but for adults it’s commonly once daily, taken before a meal. Do not chew or crush the tablets; swallow whole with water.
- If you miss a dose, take it as soon as you remember unless it’s almost time for your next dose. Do not double up.
Common side effects
- Headache, diarrhea, nausea, wind, upset stomach
- More rarely: dizziness, vomiting
Less common but important risks (especially with long-term use)
- Magnesium deficiency, low vitamin B12 deficiency
- Bone fractures with long-term use, kidney problems, liver enzyme elevations
- C. difficile infection in the gut
- Rare allergic reactions or skin rashes
Drug interactions to be aware of
- Pantoprazole can affect absorption of drugs that require acidic pH (for example, some antifungals or certain HIV drugs). It may modestly reduce the effectiveness of clopidogrel (though clinical impact varies).
- Tell your clinician about all medicines you take, including over-the-counter drugs and supplements.
Safety notes
- Pregnant or breastfeeding individuals should discuss risks with a clinician.
- Inform your doctor if you have liver or kidney disease, osteoporosis, or a history of stomach problems.
- If you have persistent symptoms, severe abdominal pain, trouble swallowing, or black stools, seek medical attention promptly.

- What condition you’re taking pantoprazole for (GERD, ulcers, etc.)
- Your dose (if known) and whether you’re looking for dosing guidelines, side effects, interactions, or something else
- Any other medicines you’re taking
