What the FDA labels say about taking them together
Fosamprenavir and simvastatin
Fosamprenavir's FDA label of September 15, 2023 names simvastatin in its contraindications section; the simvastatin label PlainMeds reads does not name fosamprenavir. The fosamprenavir label: “Coadministration with lovastatin or simvastatin is contraindicated due to potential for serious reactions such as risk of myopathy including rhabdomyolysis.”
