Naltrexone can help to reduce cravings, but it does not completely stop them. Naltrexone works by blocking the effects of opioids and endorphins in the brain, which can reduce cravings for substances like alcohol or opioids.

However, the effectiveness of Naltrexone in reducing cravings can vary depending on the individual and their specific circumstances. Some people may experience a significant reduction in cravings, while others may experience only a partial reduction.

It is also important to note that Naltrexone should be used in combination with other forms of treatment, such as counseling or support groups, to achieve the best outcomes. Additionally, it is important to talk to a healthcare provider to determine if Naltrexone is right for you and to discuss potential side effects and drug interactions.
