The effects of one injection last for a full month. In a clinical trial in Russia, 86 percent of people taking Vivitrol hadn’t relapsed after six months, while only 57 percent of placebo patients had stayed clean. However, researchers note that methadone isn’t available in Russia, and say it might be harder to convince addicts in the United States to opt for this treatment.
