Pantoprazole Use During Pregnancy
Yes, pantoprazole can be safely used during pregnancy when clinically indicated, as available data from observational studies and animal reproduction studies have not demonstrated an association with major malformations or adverse pregnancy outcomes. 1
Evidence Supporting Safety
The FDA drug label for pantoprazole explicitly states that available data from published observational studies did not demonstrate an association of major malformations or other adverse pregnancy outcomes with pantoprazole use. 1 Animal reproduction studies in rats at doses up to 88 times the recommended human dose and in rabbits at doses up to 16 times the recommended human dose revealed no evidence of harm to the fetus. 1
For gastroesophageal reflux disease during pregnancy, physicians can recommend proton pump inhibitors (including pantoprazole) as safe and effective treatment options. 2
Supporting Clinical Data
A large multicentre prospective controlled study by the European Network of Teratology Information Services followed 53 pregnancies exposed to pantoprazole (47 in the first trimester) and found the rate of major congenital anomalies was 2.1%, which did not differ from the control group rate of 3.8%. 3 This study specifically concluded that proton pump inhibitors do not represent a major teratogenic risk in humans. 3
A meta-analysis comparing 1,530 pregnant women exposed to PPIs in at least the first trimester with 133,410 unexposed pregnant women showed no significant increases in risk for congenital malformations (OR=1.12,95% CI 0.86 to 1.45) or spontaneous abortion (OR=1.29,95% CI 0.84 to 1.97). 1
Clinical Considerations
The key principle is that uncontrolled maternal disease often poses greater risks to both mother and fetus than appropriate medication use. 4 Severe gastroesophageal reflux that is refractory to H2-receptor antagonists warrants treatment with proton pump inhibitors during pregnancy. 5, 6
When prescribing pantoprazole during pregnancy, use the lowest effective dose needed to control symptoms. 1 The standard dose of 40 mg once daily has been studied and found to be well-tolerated. 3, 5
Breastfeeding Considerations
Pantoprazole has been detected in breast milk after a single 40 mg oral dose, but there were no effects observed on the breastfed infant. 1 Peak omeprazole concentrations in breast milk were less than 7% of peak serum concentrations, indicating minimal secretion into breast milk. 6
Common Pitfalls to Avoid
Do not withhold necessary acid suppression therapy due to unfounded pregnancy concerns, as inadequately treated severe reflux can lead to maternal complications including esophagitis, bleeding, and nutritional deficiencies. 5, 6 The risks of untreated disease exceed the theoretical risks of pantoprazole use. 4
