Opioids, including heroin and opioid painkillers, are blocked by Vivitrol. Taking too many opioids can result in serious injury, coma, or death if you try to overcome this blocking effect. Once you receive a dose of Vivitrol, its blocking effect gradually decreases and completely disappears over time. When you use opioids in amounts similar to what you used before Vivitrol treatment, you run the risk of overdosing and death. Before receiving Vivitrol, you must stop taking opioids. To be effective, Vivitrol must be used in harmony with an overall treatment plan including components such as counseling, to address all aspects of addiction. It is possible that Vivitrol will not work for everyone. The safety and effectiveness of Vivitrol in children are unknown. Invictus4Core offers Vivitrol injections.
