Fat redistribution and accumulation observed with ART therapy

Immune reconstitution syndrome reported, including the occurrence of autoimmune disorders (eg, Graves disease, polymyositis, Guillain-Barre syndrome) with variable time to onset; autoimmune disorder can occur many months after initiation of treatment; during initial phase of combination antiretroviral treatment, patients whose immune system responds may develop an inflammatory response to indolent or residual opportunistic infections [such as Mycobacterium avium infection, cytomegalovirus, Pneumocystis jirovecii pneumonia (PCP), or tuberculosis], which may necessitate further evaluation and treatment

Not recommended for use during pregnancy; substantially lower exposures of cobicistat and elvitegravir reported during second and third trimesters
