How long nateglinide keeps
No nateglinide label we read sets a separate limit for after opening, but they do specify how it must be stored — and the stability behind any date assumes those conditions.
Does nateglinide expire? The in-use limits and storage rules from its labelsNateglinide and breastfeeding
From LactMed, the US National Library of Medicine’s Drugs and Lactation Database — quoted, not rewritten.
Full LactMed record for nateglinide: levels in milk, effects in breastfed infants, and the drugs it would consider insteadNo information is available on the use of nateglinide during breastfeeding. Nateglinide is a weak acid that is over 98% protein bound, so it is unlikely to pass into breastmilk in clinically important amounts. Monitor breastfed infants for signs of hypoglycemia such as jitteriness, excessive sleepiness, poor feeding, seizures cyanosis, apnea, or hypothermia. If there is concern, monitoring of the breastfed infant's blood glucose is advisable during maternal therapy with nateglinide. However, an alternate drug may be preferred, especially while nursing a newborn or preterm infant.

What people report to the FDA about nateglinide
The FDA Adverse Event Reporting System (FAERS) collects reports from patients and clinicians. It holds 1,421 reports naming nateglinide, and the FDA flagged 71% 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:
- blood glucose increased84 reports
- diarrhoea66 reports
- dyspnoea66 reports
- nausea64 reports
- fatigue60 reports
- renal failure53 reports
- decreased appetite51 reports
- vomiting50 reports
Read these as a signal, not a rate. A report does not mean nateglinide 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 nateglinide 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 nateglinide against whatever else you take — and remember that a label not naming a drug is not the same as that combination being safe.
What forms does nateglinide come in?
Across the brands we track, nateglinide is currently marketed as tablet, 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 nateglinide?
We do not currently list a generic-labelled nateglinide product. That does not always mean none exists — it means none appears under a generic name in the FDA data we track. Ask your pharmacist.
