What people report to the FDA about amprenavir
The FDA Adverse Event Reporting System (FAERS) collects reports from patients and clinicians. It holds 320 reports naming amprenavir, and the FDA flagged 95% 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:
- viral mutation identified52 reports
- drug resistance45 reports
- pathogen resistance41 reports
- treatment failure36 reports
- virologic failure35 reports
- diarrhoea22 reports
- pyrexia21 reports
- lipodystrophy acquired14 reports
Read these as a signal, not a rate. A report does not mean amprenavir 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 amprenavir 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 amprenavir 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 amprenavir come in?
Across the brands we track, amprenavir is currently marketed as capsule and solution, 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 amprenavir?
We do not currently list a generic-labelled amprenavir 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.
