Barriers to initiation of extended release naltrexone among HIV-infected adults with alcohol use disorders

Alcohol consumption is a major risk factor for the acquisition of HIV/AIDS and is associated with greater disease burden and mortality among those who become HIV-infected. Of the extant pharmacological treatments for alcohol use disorders, naltrexone is recognized as one of the most efficacious, producing robust reductions in alcohol craving and use. Given that treatment with oral naltrexone has been limited by problems with adherence, which are particularly prevalent among individuals with multiple chronic, co-occurring conditions, long-acting formulations may be a promising approach for HIV-infected substance users. However, little is known about the barriers to initiation of extended-release naltrexone (XR-NTX) treatment among alcohol users living with HIV. In this report we present and discuss the content analysis of open-ended survey questions, as well as lessons learned, with regards to barriers to initiation and maintenance of XR-NTX treatment collected as part of an RCT evaluating a cognitive behavioral text messaging intervention for HIV-infected adults with alcohol use disorders. Barriers to initiation and maintenance of XR-NTX pharmacotherapy among HIV + individuals with alcohol use disorders seem to fall in one of two categories: [1] barriers that are amenable to change, which include distance and transportation issues, fear of injections, and belief that alcohol use does not warrant pharmacotherapy, and [2] barriers that are not amenable to change, such as the potential interaction of XR-NTX with another medication regimen.
