Vivitrol is a non-addictive injectable medication that is FDA-approved for alcohol use disorder and opioid use disorder. The active ingredient in Vivitrol, naltrexone, works to block the effects of alcohol and opioids and can help you prevent relapse as a part of a comprehensive addiction treatment program.
Vivitrol is the brand name for extended-release injectable naltrexone. This medication can be used in the treatment of drug or alcohol dependence and must be administered by a healthcare professional.
Vivitrol works by blocking the effects of opioids or alcohol to minimize feelings like euphoria or cravings. This can help you avoid relapse if you want to stop using these substances.
Naltrexone, the main ingredient in Vivitrol, is non-controlled. This means there is no risk of dependence on this medication or withdrawal if it were stopped.
Regardless of your addiction severity, Vivitrol must be administered by a healthcare professional, which may be a downside of using this medication for some. Vivitrol also cannot be reversed in the case of emergency surgery or other unforeseen circumstances where urgent or emergent pain control may be needed. It is important to notify your medical professional that you are on this medication.
On the other hand, Vivitrol does not require you to remember to take a daily medication like other formulations of naltrexone. This can significantly benefit those who may not want to take a daily medication.
Using Vivitrol can support sobriety by decreasing cravings for alcohol and dulling positive feelings if you drink. It does this by altering signaling in the brain and, as a result, works best when taken over time with other elements of a comprehensive treatment plan. It is important not to miss any doses of this medication.
Vivitrol works for opioid addiction by binding to the same brain receptors as opioids (mu opioid receptors) but not activating them. By doing so, Vivitrol can help reduce cravings. This medication also reduces the effect of opioids because naltrexone, the active ingredient in Vivitrol, has a higher affinity for these receptors. Essentially, if both Vivitrol and an opioid are present in the brain, the receptor will “choose” Vivitrol, meaning the opioid cannot also bind to that receptor.
Vivitrol is an opioid antagonist, meaning it blocks mu opioid receptors, which can reduce alcohol or opioid cravings. It is crucial to be opioid and alcohol-free during administration. If not, Vivitrol can cause serious and uncomfortable opioid withdrawal symptoms by removing opioids from these receptors.
Vivitrol is injected once every four weeks into a gluteal muscle and should alternate buttocks each month. This can only be done by a healthcare professional. You may notice injection site reactions which include pain, itching, bruising, swelling or redness. If this does not go away within two weeks, notify your healthcare provider.
Vivitrol begins working in the body about two hours after injection. Then the amount of medication in the body continues to increase until about day 14, when it slowly starts to decrease. Due to this, Vivitrol only needs to be given once every four weeks and is effective for a month.
Common side effects of Vivitrol may include:
Vivitrol can cause rare but serious side effects. Seek medical help if you experience any of the following:
Vivitrol has its first peak about two hours after the injection is given in the body. A second peak usually occurs about two to three days after injection, continuing until about day 14. The concentration of Vivitrol in the body slowly starts decreasing after this time.
Whether you should drink on Vivitrol should always be discussed with your healthcare provider. For alcohol use disorder (AUD), Vivitrol is FDA-approved only for those who are not drinking and do not plan to drink.
The answer to this question for opioid use disorder (OUD) can vary from person to person. Most often, you can drink in moderation, but always speak with a healthcare professional for questions regarding your specific situation.
It is recommended that you are opioid-free for at least seven days before starting Vivitrol. If opiates are still in your system when you start this medication, Vivitrol can cause opioid withdrawal. These symptoms may include:
In a study conducted by the National Institute of Drug Abuse, Vivitrol was 90% effective at reducing opioid addiction over six months. This study also showed that 55% of patients reported reduced opioid cravings.
However, Vivitrol requires full detoxification. Initiating treatment with patients actively dependent on alcohol or opioids can be more difficult than other medications, like Suboxone. Once started, Vivitrol is as effective as similar medications.
Vivitrol is most often prescribed by a specialty pharmacy and usually requires that your healthcare provider fills out paperwork for your insurance company. Once the medication arrives, your healthcare provider will inject it and schedule your next appointment.
