Does Vivitrol treat opioid and alcohol cravings?
Vivitrol (naltrexone) is used for both opioid dependence and alcohol dependence, and it can reduce the urge to use in both cases. It works by blocking opioid receptors, which can lower the reward people get from alcohol (indirectly through endorphin pathways) and from opioids (directly). [1]
How does Vivitrol help with opioid cravings?
For opioid dependence, Vivitrol helps prevent relapse by reducing the rewarding effects of opioids. That can reduce craving and help people stay off opioids during treatment. [1]
How does Vivitrol help with alcohol cravings?
For alcohol dependence, Vivitrol is used to help maintain abstinence and reduce heavy drinking. By dampening alcohol-related reward signaling, it can reduce craving and the urge to drink. [1]
Does it work for cravings even if someone still uses?
Vivitrol only helps if it can block the effects of the substance. For opioids, people must be opioid-free before starting Vivitrol to avoid precipitated withdrawal, since Vivitrol blocks opioid receptors. [1] For alcohol, Vivitrol is generally used as part of alcohol dependence treatment and is not a substitute for ongoing clinical support. [1]
What patients usually ask: is Vivitrol for both at the same time?
If someone has both opioid dependence and alcohol dependence, clinicians may consider whether Vivitrol fits their treatment plan, since the medication has approved uses in both conditions. That said, suitability depends on the person’s medical history, current substance use, and ability to safely start naltrexone. [1]
Important safety/eligibility issues
Naltrexone is not appropriate for everyone. For opioids, it must be started only when the person is opioid-free to avoid withdrawal. Liver health matters for people with alcohol-related liver disease, so clinicians typically assess liver function before and during treatment. [1]
