Risks and Warnings for Vivitrol (Naltrexone)

Skip risks section. Skip to common concerns section.
    • Higher risk if:
    • Prior use of opioid medications
    • Use of Vivitrol (Naltrexone)

    After opioid detoxification, people are likely to have a reduced tolerance to opioids. If people who have been treated with Vivitrol (Naltrexone) need to use opioid pain medications in the future, they'll need lower doses of opioids than they used before they started taking Vivitrol (Naltrexone). If you give them the opioid dose they used to get, it could result in a potentially life-threatening overdose. People should be alerted that they'll be more sensitive to opioids in the future.
