What happens if I use drugs while taking naltrexone?

Naltrexone (ReVia, Vivitrol) is a drug that helps drug addicts and alcoholics stay clean when used in conjunction with addiction treatment programs. It works by blocking the effects of opioids such as morphine and heroin and decreasing the craving for alcohol.

If you take large doses of heroin or any other opioid, including methadone or levo-α-acetylmethadol (LAAM) at the same time you are receiving naltrexone, you may experience serious complications, coma or death. Doctors recommend that people receiving naltrexone wear a medic alert bracelet to let emergency care workers know they are taking this drug, as it can influence what emergency treatment they give you. Also, let all your doctors and pharmacists know you are taking naltrexone.
