Vivitrol is an extended-release injectable form of naltrexone, an opioid antagonist.
Its use for alcohol dependence is intended for people who can abstain in an outpatient setting before treatment begins and who are not actively drinking at the initial administration. That indication is distinct from managing acute withdrawal. If alcohol withdrawal is occurring or may occur, Vivitrol should not be treated as a substitute for appropriate withdrawal assessment and care. Medication initiation decisions must remain with a qualified prescribing clinician.
