Drug Facts

ClassNucleoside analogue antiviral (acyclic guanosine)
MechanismSelectively phosphorylated by viral thymidine kinase to acyclovir monophosphate, then by host kinases to acyclovir triphosphate, which inhibits viral DNA polymerase and terminates viral DNA chain elongation. Active against HSV-1, HSV-2, VZV; modest activity against EBV, CMV.
Typical dosing400 mg PO twice daily for HSV/VZV prophylaxis during proteasome inhibitor therapy

Notes

HSV/VZV prophylaxis is mandatory during proteasome inhibitor therapy (bortezomib, carfilzomib, ixazomib) due to substantially increased risk of herpes zoster reactivation. Renal dose adjustment required if CrCl <50 mL/min. Valacyclovir (500 mg PO daily) is an acceptable prodrug alternative with better bioavailability.
