What are the Side Effects of Vivitrol?

Vivitrol is a medication prescribed to people addicted to heroin, Fentanyl, or prescription pain killers. Vivitrol is a once-a-month intra-muscular injection, an extended-release formula of Naltrexone that helps someone remain opioid-free. It reduces cravings for opioids, making recovery from the addiction easier. Vivitrol is Naltrexone, which was only prescribed in pill form to be taken once a day. Vivitrol is quickly becoming the preferred medication to help people remain off of opiate drugs long-term. The opioid drug epidemic is still in full force, and the arrival of a once-a-month medication-assisted treatment (MAT) is well supported. 

The success of Vivitrol is immense. Like other medication-assisted treatment for opioid addiction, which is now termed opioid use disorder or OUD. We can connect you to a Vivitrol-providing addiction center in New York by the end of the day. Vivitrol is currently helping thousands of addicts recover from their addiction and begin a new life finally free of physical, mental, and emotional dependency on opioids.

How Does Vivitrol Help People Recover?

Vivitrol is used the same way that the drug Suboxone is to help people recover from their opioid use disorder (addiction). Vitriol is often prescribed following Suboxone. In general, the use of opioid replacement drugs as MATs to treat addiction to opioids is now standard in any successful opioid addiction treatment program. Suboxone and Vivitrol make staying clean easier because they reduce drug cravings. Vivitrol is, however, different from Suboxone; it must only be prescribed and ingested after one week from the last opioid use of either heroin, Fentanyl, prescription pain killers, and other opiates.     

According to the Substance Abuse and Mental Health Services Administration, Vivitrol must only be prescribed after 7-10 days after the last use has passed since the person last took opiates. This is because Vivitrol blocks the effects of opiates and, therefore, can cause unwanted physical withdrawal symptoms to occur rapidly. 

“Extended-release injectable Naltrexone is approved for the treatment of people with opioid use disorder. Medically managed withdrawal (detoxification) from opioids must be completed at least 7 to 10 days before extended-release injectable Naltrexone (Vivitrol) is initiated or resumed. Research has shown that Naltrexone decreases reactivity to drug-conditioned cues and decreases craving. Extended-release Naltrexone should be part of a comprehensive management program that includes psychosocial support.” (SAMHSA). 

What Are The Side Effects Of Vivitrol?

The side effects that Vivitrol may cause can be life-threatening. It is an opioid replacement drug that can cause an overdose. Yet, there are mild side effects that are not as dangerous. Some people experience these symptoms when taking Vivitrol: Headache, Nausea, Diarrhea, Constipation, Drowsiness, Dizziness, Dry Mouth, Anxiety, Lethargy, Depression. The pharmaceutical company ALKERMES that manufactures Vivitrol, highlights the four hazardous side effects that can occur when taking Vivitrol: 

  1. Risk of opioid overdose – VIVITROL blocks the effects of opioids, such as heroin or opioid pain medicines. If you have used opioid street drugs or opioid-containing medicines in the past, using opioids in amounts you used before treatment with VIVITROL can lead to overdose and death. 
  2. Severe reactions at the site of injection – Some people on VIVITROL have had severe injection site reactions, including tissue death. Some of these reactions have required surgery. A healthcare provider must inject VIVITROL. Tell your healthcare provider about any reaction at an injection site that concerns you, gets worse over time, or does not get better within two weeks.
  3. Sudden opioid withdrawal – To avoid sudden opioid withdrawal, you must stop taking any type of opioid, including street drugs; prescription pain medicines; cough, cold, or diarrhea medicines that contain opioids; or opioid-dependence treatments, including buprenorphine or methadone, for at least 7 to 14 days before starting VIVITROL.
  4. Liver damage or hepatitis – Naltrexone, the active ingredient in VIVITROL, can cause liver damage or hepatitis. (ALKERMES)
