As I'm on PEP medication course of 28 days currently I've taken one pill. In coming days as the medicine starts circulating in blood, what factors should be monitored in body so as to ensure no serious side effects are happening? Also what should be the frequency of getting health checkup done to ensure vital organs are not getting damaged by PEP medicine. Also tell what all tests do need to be done? Wil the PEP medicine cause any serious damage to vital organs like kidney or liver? I've no history of any health issues regarding liver, kidneys etc.
