To measure the incidence of neuropsychiatric adverse drug reactions (ADRs) in individuals living with HIV who initiated antiretroviral therapy (ART) with first-line regimens containing dolutegravir (DTG) or efavirenz (EFV) and associated factors.

Prospective cohort study with individuals living with HIV who started ART with DTG or EFV associated with tenofovir disoproxil and lamivudine in Belo Horizonte, Brazil. Sociodemographic, clinical, and laboratory data were collected from September 2015 to October 2018 in three specialized HIV care services through interviews, clinical records, and computerized systems. We analysed the frequency of neuropsychiatric ADRs recorded in clinical records 12 months after starting antiretroviral use, and the associated factors were investigated using binary logistic regression.

A total of 152 (35.1%) of the 433 individuals included had neuropsychiatric ADRs. The incidence density was 35.3/100 person-years. The subjects mainly had sleep disorders and disturbances (21.3%), neurological disorders (13.9%), headaches (8.1%), and anxiety disorders and symptoms (3.0%), more frequently in individuals using EFV. A lower likelihood of neuropsychiatric ADRs was associated with using a DTG-based antiretroviral regimen (OR = 0.24; 95% CI = 0.14–0.40) and anxiety or depression signs and symptoms at the onset of treatment (OR = 0.57; 95% CI = 0.37–0.89).

The incidence of neuropsychiatric ADRs was high in individuals starting ART with a lower likelihood of using a DTG-based regimen. The DTG-based regimen had a better safety profile for neuropsychiatric ADRs than the EFV-based regimen.
