Noticeably lowered nirmatrelvir plasma concentrations may very well be affiliated with possible for lack of virologic response and possible resistance. Do not initiate nirmatrelvir/ritonavir straight away immediately after discontinuing a powerful 3A4 inducer owing to time needed for systemic clearance with the inducer.
