Vivitrol is an injectable form of naltrexone, an opiate antagonist. The medicine binds to opioid receptors in the body and blocks the effects of any kind of opiate high. Vivitrol also blocks the euphoric effects of alcohol to a lesser extent. Vivitrol is helpful for anyone looking to overcome a crippling addiction to either alcohol or opiates, however, any other kind of substance will not be affected by Vivitrol.


Drugs Affected by Vivitrol

  • Alcohol
  • Opium
  • Heroin
  • Hydrocodone (Vicodin)
  • Oxycodone (OxyContin)
  • Oxymorphone (Opana)
  • Morphine (Kadian / Avinza)
  • Codeine
  • Fentanyl
  • Carfentanil
  • Methadone



  • Marijuana
  • Benzodiazepines
  • Methamphetamine
  • Amphetamine
  • Cocaine
  • Hallucinogens
  • Inhalants


Vivitrol, like all forms of naltrexone, works by stopping the euphoria associated with opiates, targeting the same central nervous system neurotransmitters that alcohol and opiates bind to. The medicine binds to these receptors and boxes out the opiates from staying there. Vivitrol is injected directly into the muscle through an intravenous shot. The drug has a long half life and remains in the body for up to one month after injection.


What is Vivitrol Used For?

Vivitrol is the brand name for naltrexone and is used to help recovering opiate and alcohol addicts stay sober. The drug blocks any sort of euphoria associated with each drug, making the consumption of these drugs useless. Vivitrol is available in a monthly shot, or in oral tablet form. Anyone taking Vivitrol needs to completely detox from opiates and alcohol for 7-10 days prior to the first dosage.


Vivitrol Testimonials

Vivitrol can work wonders for those in recovery who wish to truly live a life free from the effects of drugs and alcohol. The following are real testimonials from Bluelight forum, an online platform for sharing stories and experiences about illicit substance use.


“I have not really had any negative side effects from the shot. I have had 2-3 months period of time where I did not use in between shots, and mentally and physically I could not tell any difference when my shot wore off or when I received my new shot. For me, with no opiates in my system, the shot is like receiving in injection of water, no side effects whatsoever, aside from a little bump in my butt muscle that is uncomfortable for a few days.”


“I got on Vivitrol 9 months ago and it has done a complete 360 for my life. In order to get on Vivitrol, you need to pass a urine test for all opiates including suboxone, the company recommends 7-10 clean. When I received my first shot I was only 5 days clean and did not have any adverse reactions to the injection.”


“I'm on vivitrol and it's a godsend, but only if you want to stay clean and could use the help of the crutch that is vivitrol for the first year.”


“If you truly and full heartedly want to be clean and sober, and experience what life on the other side had to offer you, then I would highly recommend this drug for you. For those of us though who aren't quite ready to quit cold turkey and have a medication completely alter way of life, I would recommend you stay far away from this drug. It’s not for people who aren't ready to quit.”


Is Vivitrol Safe?

An individual getting their vitals measured in order to make sure they are healthy and detoxed before taking vivitrol.

Vivitrol can be as effective as Suboxone for maintaining long term sobriety. Unlike Suboxone, patients using Vivitrol do not run the risk of becoming addicted to the drug. Vivitrol does not have a high associated with using it, however, there are still risks to taking this medication. Since Vivitrol blocks the effects of opiates over the period of a month, patients will be able to feel a diluted form of the high they used to get towards the end of the month. Patients using Vivitrol may also attempt to get high through opioids after their injection. However, since the receptors are being blocked, they may increase their dosage and reach toxic levels of the drug in their system.


Patients who stop taking Vivitrol also increase their chance of fatal overdose if they wind up relapsing. The body has not been subject to the same levels of opioid influence as they were before, so they could potentially take a fraction of the dosage they used to take and wind up overdosing. Patients also must detox for a period of 7-10 days prior to the first injection. This period of detox needs to be free from any other form of opiate such as Suboxone or Methadone. Going cold turkey from opioids can be extremely painful and a small fraction of patients who start a Vivitrol program do not make it past this portion.
