Vivitrol/Naltrexone Q & A

What is VIVITROL® and Naltrexone?

Vivitrol, also known as Naltrexone (which is the active ingredient), is an extended-release medication that Dr. David Sherman prescribes to treat opioid or alcohol dependence.It helps to prevent relapse when used in conjunction with individual or group counseling. Before you begin Vivitrol injections, you should stop drinking on your own or as part of a rehabilitation program.  Dr. Sherman will discuss the various options with you.

The benefit of using Vivitrol is that it’s non-addictive and not a narcotic. Dr. Sherman may prescribe Vivitrol to prevent relapse after you’ve completed the detoxification portion of a rehabilitation program.

How does Vivitrol and Naltrexone work?

Vivitrol helps prevent alcohol- or opioid-dependence relapse.

Alcohol dependence

If you’re alcohol dependent, Vivitrol is a non-addictive medication that reduces the urge for heavy drinking.

Opioid dependence

Vivitrol works to treat opioid dependence by blocking the effects of opioids. This injectable helps prevent relapse after detoxification, but you must stop taking opioids or treatment medications for 7-14 days before receiving Vivitrol to avoid withdrawal.

After a Vivitrol injection, its opioid-blocking effects slowly decrease over time, which is why it’s a monthly injectable. Using high doses of opioids with Vivitrol can lead to an overdose, so it’s important to follow Dr. Sherman’s instructions.

Does Vivitrol and Naltrexone cause side effects?

Possible side effects associated with Vivitrol injections are reactions at the injection site, sudden withdrawal, and liver damage. Symptoms of a reaction at the injection site include:

  • Pain
  • Lumps
  • Swelling
  • An open wound
  • A blister or dark scab

You may not be a candidate for Vivitrol therapy if you have significant liver damage due to hepatitis or cirrhosis.  Discuss any history of liver problems with Dr. Sherman.

  • Nausea
  • Vomiting
