Nizatidine and breastfeeding
From LactMed, the US National Library of Medicine’s Drugs and Lactation Database — quoted, not rewritten.
Full LactMed record for nizatidine: levels in milk, effects in breastfed infants, and the drugs it would consider insteadBecause of the low levels of nizatidine in breastmilk, amounts ingested by the infant are small and would not be expected to cause any adverse effects in breastfed infants. No special precautions are required. Histamine H2-antagonists with more extensive use might be preferred in newborns.

What people report to the FDA about nizatidine
The FDA Adverse Event Reporting System (FAERS) collects reports from patients and clinicians. It holds 1,621 reports naming nizatidine, and the FDA flagged 86% of those reports as serious. The effects reported most often — leaving out reports about overdose, misuse or the condition being treated, which dominate the raw list for common medicines:
- chronic kidney disease272 reports
- acute kidney injury166 reports
- renal failure139 reports
- nausea79 reports
- end stage renal disease75 reports
- vomiting69 reports
- dyspnoea66 reports
- gastrooesophageal reflux disease64 reports
Read these as a signal, not a rate. A report does not mean nizatidine caused the effect — anyone can file one, and many describe people taking several medicines for several conditions. Crucially there is no denominator: FAERS does not record how many people took the drug, so these counts cannot be turned into “X% of patients” — a bigger number often just means a more widely used or more talked-about drug. Duplicates exist, and publicity drives reporting. For what is actually established, read the FDA label section above.

Frequently asked questions
Can you take nizatidine with other medicines?
It depends on the medicine. We check it against the FDA labels rather than guessing: our interaction checker searches each drug's own label for the other and quotes what it says, naming the section it came from. Run nizatidine against whatever else you take — and remember that a label not naming a drug is not the same as that combination being safe.
What brand names is nizatidine sold under?
We track 2 nizatidine-containing products in the U.S.: Nizatidine and Axid. They are the same active ingredient; they differ in form, manufacturer, price and FDA recall record.
What forms does nizatidine come in?
Across the brands we track, nizatidine is currently marketed as solution and capsule, per the FDA's National Drug Code Directory. Each form is dosed differently — follow the label for the exact product you were prescribed.
Is there a generic nizatidine?
Yes. Our catalog lists 1 generic nizatidine product alongside the brand versions. A generic has the same active ingredient and must meet the FDA's bioequivalence standard; it usually costs less. Ask your pharmacist which one your plan covers.
