Tolerability of postexposure prophylaxis with the combination of zidovudine-lamivudine and lopinavir-ritonavir for HIV infection.

Tolerability of the combination of zidovudine-lamivudine and lopinavir-ritonavir as postexposure prophylaxis (PEP) for human immunodeficiency virus infection was prospectively assessed. A total of 121 patients were enrolled in the study; 23 patients discontinued PEP prematurely for reasons other than adverse events. Of the other 98 patients, 58 (59%) experienced adverse effects, which led to premature PEP discontinuation in 20 cases (20%).
