From the Guidelines
Pantoprazole can cause several side effects, including diarrhea, gastrointestinal infections, and magnesium deficiency, and if these side effects occur, consideration should be given to switching to alternative treatments, as recommended by the British Society of Gastroenterology guidelines 1.
Common Side Effects
The most common side effects of pantoprazole include:
- Headache
- Diarrhea
- Nausea
- Stomach pain
- Vomiting
- Gas
- Dizziness
- Joint pain Most of these effects are mild and often resolve as the body adjusts to the medication.
Serious Side Effects
More serious but less common side effects include:
- Severe stomach pain
- Difficulty swallowing
- Persistent diarrhea (especially with blood)
- Vitamin B12 deficiency (with long-term use)
- Low magnesium levels (causing muscle spasms, irregular heartbeat, or seizures)
- Kidney problems Rarely, pantoprazole may increase the risk of bone fractures with prolonged use, particularly in older adults. Long-term use has also been associated with an increased risk of intestinal infections like Clostridium difficile.
Management of Side Effects
If severe side effects occur, particularly persistent diarrhea, signs of kidney problems (such as changes in urination), or symptoms of low magnesium, it is essential to contact a healthcare provider immediately. The literature on PPI side effects is extensive, and while associations are often described, proof of causal association is not always clear 1. Therefore, switching away from PPI therapy should only be considered if the side effects are clearly caused by the PPI, as recommended by the guidelines 1.
Alternative Treatments
In cases where pantoprazole causes unwanted side effects, alternative treatments such as diet or topical steroid therapy may be considered, as suggested by the British Society of Gastroenterology guidelines 1. However, it is crucial to weigh the benefits and harms of de-prescribing PPIs, particularly in patients with a history of severe erosive esophagitis or GERD-related complications, as noted in the AGA clinical practice update on de-prescribing of proton pump inhibitors 1.

Pantoprazole sodium delayed-release tablets can cause serious side effects, including: Low vitamin B-12 levels in your body can happen in people who have taken pantoprazole sodium delayed-release tablets for a long time (more than 3 years). Low magnesium levels in your body can happen in people who have taken pantoprazole sodium delayed-release tablets for at least 3 months. Stomach growths (fundic gland polyps) The most common side effects of pantoprazole sodium delayed-release tablets in adults include: headache, diarrhea, nausea, stomach-area (abdominal) pain, vomiting, gas, dizziness, and joint pain The most common side effects of pantoprazole sodium delayed-release tablets in children include: upper respiratory infection, headache, fever, diarrhea, vomiting, rash, and stomach-area (abdominal) pain.

From the Research
Side Effects of Pantoprazole
The provided studies do not extensively discuss the side effects of pantoprazole. However, some information can be gathered:
- Pantoprazole has an excellent safety profile and a low incidence of drug interactions 3, 4, 5, 6.
- It is well tolerated in patients with acid-related disorders in short- and long-term trials 4, 6.
- Tolerability with oral pantoprazole was similar to that with other PPIs or histamine H(2)-antagonists in short-term trials 6.
- Formal drug interaction studies have not revealed any clinically significant interactions between pantoprazole and other agents 6.
Special Considerations
Some studies mention the use of pantoprazole in special patient populations:
- Pantoprazole has been shown to be safe and effective in special patient populations, such as the elderly and those with renal or moderate liver disease 3.
- It is also effective in treating and preventing NSAID-related gastric and gastroduodenal injury 4, 6.
- Pantoprazole 20 or 40 mg/day was effective and well tolerated in the treatment of acid-related disorders in children and adolescents 4.
Dosage and Administration
The optimal adult oral dose for gastric acid-related disorders is pantoprazole 40 mg once daily 4. However, some studies suggest that a higher dose of pantoprazole (80 mg) may be necessary in certain cases, such as extraesophageal symptoms, partial responders, patients with concomitant use of non-steroidal anti-inflammatory drugs (NSAIDs), or severe presentation in cases of overweight/obese patients 7.
