The CDC previously thought that infection provided about 90 days of protection, though it's become more common for people to get reinfected before then, Jha said. CYP3A4 inhibition occurs rapidly after initiating ritonavir, with maximum inhibition occurring within 48 hours.28 After ritonavir is discontinued, 70% to 90% of CYP3A4 inhibition resolves within 2 to 3 days.29 The time to resolution of inhibition varies based on factors such as the patients age; therefore, resolution may take longer in some individuals, such as in adults of advanced age.
