Enfuvirtide and breastfeeding
From LactMed, the US National Library of Medicine’s Drugs and Lactation Database — quoted, not rewritten.
Full LactMed record for enfuvirtide: levels in milk, effects in breastfed infants, and the drugs it would consider insteadNo published information is available on the use of enfuvirtide during breastfeeding. Enfuvirtide is not a recommended agent during breastfeeding. Achieving and maintaining viral suppression with antiretroviral therapy decreases breastfeeding transmission risk to less than 1%, but not zero. Individuals with HIV who are on antiretroviral therapy with a sustained undetectable viral load and who choose to breastfeed should be supported in this decision. If a viral load is not suppressed, banked pasteurized donor milk or formula is recommended.

What people report to the FDA about enfuvirtide
The FDA Adverse Event Reporting System (FAERS) collects reports from patients and clinicians. It holds 1,890 reports naming enfuvirtide, and the FDA flagged 98% 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:
- depression503 reports
- psychotic disorder288 reports
- nausea233 reports
- vomiting225 reports
- pneumonia214 reports
- loss of personal independence in daily activities211 reports
- cholelithiasis195 reports
- schizophrenia195 reports
Read these as a signal, not a rate. A report does not mean enfuvirtide 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 enfuvirtide 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 enfuvirtide 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 enfuvirtide come in?
Across the brands we track, enfuvirtide is currently marketed as injectable, 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 enfuvirtide?
We do not currently list a generic-labelled enfuvirtide 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.
