You should carry or wear medical identification stating that you are taking this drug so that appropriate treatment can be given in a medical emergency.

After stopping naltrexone treatment, you may be more sensitive to lower doses of opioids, increasing your risk of possibly life-threatening side effects from the narcotic (e.g., decreased breathing, loss of consciousness).
