Risks of hepatotoxicity

Risk of immune reconstitution syndrome if used in combination with other antiretroviral drugs

Autoimmune disorders (eg, Graves’ disease, polymyositis, Guillain-Barré syndrome) reported in the setting of immune reconstitution, however, the time to onset is more variable, and can occur many months after initiation of treatment

Do not use in treatment-naïve patients; more likely to experienced virologic failure and developed lamivudine resistance compared to efavirenz

Tropism testing with a highly sensitive tropism assay is required for the appropriate use

Evaluate if signs/symptoms of hepatitis, increase LFTs, or rash develop

Preexisting liver dysfunction or viral hepatitis B or C coinfection

Patient history of increased risk for cardiovascular events

History of postural hypotension or concomitant use of blood pressure lowering medication

Caution in renal and hepatic impairment; postural hypotension reported in patients with renal impairment

Monitor for developing infections

When administering to patients with pre-existing liver dysfunction or who are co-infected with hepatitis B and/or C virus, additional monitoring may be warranted

Cardiovascular adverse events triggered by postural hypotension’ additional monitoring may be warranted

Pregnancy: Limited data on pregnancy from the APR and case reports are not sufficient to inform a drug-associated risk of birth defects and miscarriage; n animal reproduction studies, no evidence of adverse developmental outcomes observed with maraviroc

Lactation: Centers for Disease Control and Prevention recommend that HIV-1-infected mothers in United States not breastfeed their infants to avoid risking postnatal transmission of HIV-1 infection
