HOVILPRI is indicated in immunocompromised adults for the treatment of mucocutaneous lesions caused by herpes simplex virus (HSV) infection that is refractory (with or without documented resistance) to treatment with acyclovir, valacyclovir, or famciclovir [see Clinical Studies (14.1)].
Initiate treatment with a loading dose of 400 mg (four 100 mg tablets) on day 1, followed by a maintenance dose of 100 mg (one tablet) daily by mouth with or without food, until HSV lesions have healed [see Clinical Pharmacology (12.3), Clinical Studies (14.1)].
While taking HOVILPRI, avoid concomitant use of the following proton pump inhibitors [see Warnings and Precautions (5.1), Drug Interactions (7.2), Clinical Pharmacology (12.3)]:
Take HOVILPRI 2 hours before or 12 hours after taking a H2-receptor antagonist [see Warnings and Precautions (5.1), Drug Interactions (7.2), Clinical Pharmacology (12.3)].
Separate any dosing of antacids from HOVILPRI dosing by 2 hours [see Warnings and Precautions (5.1), Drug Interactions (7.2)].
If a dose of HOVILPRI is missed, take it as soon as it is remembered. If it is not taken until the scheduled dosing time on the next day, take two tablets at that time.
There is no known specific antidote for HOVILPRI. In the event of an overdose, patients should be monitored for adverse reactions and managed with supportive care, as appropriate.
Due to the high plasma protein binding of pritelivir, hemoperfusion or dialysis is unlikely to significantly reduce systemic exposure of pritelivir. Consider contacting the Poison Help line (1-800-222-1222) or a medical toxicologist for additional overdose management recommendations.
Store at 20°C to 25°C (68°F to 77°F), excursions permitted to 15°C to 30°C (59°F to 86°F) [see USP Controlled Room Temperature].
