Vivitrol is a relatively recent drug that is commonly used for the treatment of alcohol dependence or to prevent relapse in patients struggling with opioid dependence. It can help users break free from dependence by blocking the intense high that often accompanies opioids, resulting in the user experiencing only negative effects from the substance. It also blocks any pleasurable feelings associated with alcohol use. This effect is said to help curtail the power of substance cravings.

Vivitrol is generally administered one time in a 30-day period at a dosage level of 380 mg. It is rising in popularity because of its convenient once-a-month dosage. This drug should be used in conjunction with other treatment programs as an additional tool. It should only be used under the supervision of medical professionals because, although minimal, Vivitrol side effects can be alarming.
