The details: what each source says

Pantoprazole in pregnancy

The NHS says

Pantoprazole is not usually recommended in pregnancy, because there is very little information about using it while pregnant.

Your doctor may suggest a similar medicine, omeprazole, instead, as more safety information is available for it.

If your symptoms are mild, you might want to try easing them without medicine. You could eat smaller meals more often and avoid fatty and spicy foods. Sitting up straight while you eat can also help, as it eases the pressure on your stomach.

If symptoms come on at night, raising your head and shoulders in bed can help stop stomach acid coming up while you sleep.

The US drug label says

8.1 Pregnancy Teratogenic Effects Risk Summary Available data from published observational studies did not demonstrate an association of major malformations or other adverse pregnancy outcomes with pantoprazole. In animal reproduction studies, no evidence of adverse development outcomes was observed with pantoprazole. Reproduction studies have been performed in rats at oral doses up to 450 mg/kg/day (about 88 times the recommended human dose) and rabbits at oral doses up to 40 mg/kg/day (about 16 times the recommended human dose) with administration of pantoprazole during organogenesis in pregnant animals and have revealed no evidence of harm to the fetus due to pantoprazole in this study (see Data). A pre- and postnatal development toxicity study in rats with additional endpoints to evaluate the effect on bone development was performed with pantoprazole sodium. Oral pantoprazole doses of 5, 15, and 30 mg/kg/day (approximately 1, 3, and 6 times the human dose of 40 mg/day on a body surface area basis) were administered to pregnant females from gestation day (GD) 6 through lactation day (LD) 21.

Pantoprazole while breastfeeding

The NHS says

Pantoprazole can be taken while breastfeeding.

Information about pantoprazole and breastfeeding is limited, but it shows that tiny amounts reach breast milk. Your baby won't be able to absorb much of it from the milk, so side effects are unlikely.

Side effects in breastfed babies from medicines their mother takes are very rare, but it's important to keep an eye on your baby whenever you take a medicine while breastfeeding.

Contact a healthcare professional or call 111 (NHS 111 in the UK) as soon as you can if your baby is feeding less well than normal, has constipation or diarrhoea or is vomiting (being sick), or is irritable.

For symptoms not mentioned here, or if you're worried about your baby, you can also speak to any healthcare professional or call 111.

Keep taking the medicine and carry on breastfeeding as normal until you've had advice about your baby's symptoms.

LactMed says

Maternal pantoprazole doses of 40 mg daily produce low levels in milk and would not be expected to cause any adverse effects in breastfed infants.

The US prescribing label says

Nursing Mothers Pantoprazole and its metabolites are excreted in the milk of rats. Pantoprazole excretion in human milk has been detected in a study of a single nursing mother after a single 40 mg oral dose of pantoprazole sodium. The clinical relevance of this finding is not known. Many drugs which are excreted in human milk have a potential for serious adverse reactions in nursing infants. Based on the potential for tumorigenicity shown for pantoprazole sodium in rodent carcinogenicity studies, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the benefit of the drug to the mother.
