Enflurane and breastfeeding
From LactMed, the US National Library of Medicine’s Drugs and Lactation Database — quoted, not rewritten.
Full LactMed record for enflurane: levels in milk, effects in breastfed infants, and the drugs it would consider insteadThere is no published experience with enflurane during breastfeeding. Because the serum half-life of enflurane in the mother is short and the drug is not expected to be absorbed by the infant, no waiting period or discarding of milk is required. Breastfeeding can be resumed as soon as the mother has recovered sufficiently from general anesthesia to nurse. When a combination of anesthetic agents is used for a procedure, follow the recommendations for the most problematic medication used during the procedure. In one study, breastfeeding before general anesthesia induction reduced requirements of sevoflurane and propofol compared to those of nursing mothers whose breastfeeding was withheld or nonnursing women. It is possible that requirements for other anesthetic agents would be affected similarly.

What people report to the FDA about enflurane
The FDA Adverse Event Reporting System (FAERS) collects reports from patients and clinicians. It holds 88 reports naming enflurane, and the FDA flagged 65% 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:
- myocardial ischaemia13 reports
- post procedural complication11 reports
- bradycardia9 reports
- haemolysis7 reports
- alkalosis6 reports
- oculogyric crisis6 reports
- pyrexia6 reports
- depressed level of consciousness5 reports
Read these as a signal, not a rate. A report does not mean enflurane 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 enflurane 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 enflurane 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 enflurane come in?
Across the brands we track, enflurane is currently marketed as liquid, 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 enflurane?
We do not currently list a generic-labelled enflurane 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.
