What this interaction means in plain words

Foscarnet and Peramivir can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.

Evidence level: Low

Why it happens

Foscarnet-induced nephrotoxicity may reduce renal clearance of peramivir.

What to do

Monitor renal function during co-therapy and adjust the peramivir dose according to creatinine clearance. Ensure adequate hydration.
