Vivitrol injection : Uses, Side Effects, Dosage, and Safety Information

vivitrol is a prescription medication that helps treat alcohol use disorder and opioid use disorder. It contains naltrexone in an extended-release injectable form and belongs to a class of medicines called opioid antagonists. Unlike opioid medications, Vivitrol does not cause euphoria or produce opioid-like effects. Instead, it blocks opioids from attaching to their receptors and, as a result, reduces some effects associated with opioid use. vivitrol injection buy online

Furthermore, a healthcare professional gives Vivitrol as a long-acting injection. Because the medication remains active in the body for an extended period, it provides continuous medication exposure without requiring patients to remember a daily tablet. However, Vivitrol does not serve as a standalone treatment. Rather, healthcare professionals generally use it as part of a comprehensive treatment plan that may include counseling, behavioral therapy, recovery support, and other appropriate services.

What is Vivitrol?

Vivitrol, an injectable formulation of naltrexone, is a medication utilized for treating two types of substance use disorders: opioid use disorder and alcohol use disorder (alcoholism). Vivitrol forms part of a treatment program. It aids in stopping individuals who are dependent on opioids or alcohol from experiencing a sense of necessity to resort to these substances.

Vivitrol, an opioid antagonist, functions by blocking mu opioid receptors. Additionally, it reduces your alcohol cravings by altering the interplay among your hypothalamus, pituitary gland, and adrenal gland. Vivitrol prevents the feelings of intoxication and euphoria, or ‘high,’ that alcohol and opioids induce. Additionally, it prevents the analgesic effects of opioids.

Vivitrol is a medication that is injected into the gluteal muscle and has an extended-release formulation. After being injected, it provides a slow release of naltrexone (the active substance) for approximately one month.

What is Vivitrol used for?

Vivitrol is a prescription injectable medicine used to:

• treat alcohol dependence. You should stop drinking before starting this medication.
  prevent relapse to opioid dependence, after opioid detoxification.
• This means that if you take opioids or opioid-containing medicines (sometimes called narcotics), you must stop taking them before you start receiving this medication. See Important information below.

To be effective, treatment with Vivitrol must be used with other alcohol or drug recovery programs such as counseling. This treatment may not work for everyone.

It is not known if Vivitrol is safe and effective in children.

How Does Vivitrol Work?

Vivitrol is made up of naltrexone, which acts as an opioid receptor antagonist. Once the drug is injected, naltrexone is released into the body gradually over time.

Naltrexone exhibits a high affinity for opioid receptors, especially mu-opioid receptors. Opioid drugs can trigger these receptors, leading to effects like euphoria, sedation, and analgesia. Naltrexone prevents opioids from having their usual effects by blocking these receptors.

The precise mechanism that leads to reduced alcohol consumption in cases of alcohol use disorder is not fully understood. Nonetheless, it is thought that naltrexone affects the brain pathways associated with alcohol’s rewarding effects.

How Is Vivitrol Administered?

Vivitrol is given via an intramuscular injection, typically targeting the gluteal muscle. A qualified healthcare professional using the appropriate injection technique should administer it.

The prescribed treatment plan usually involves administering the medication once every four weeks or roughly once a month.

It is not advisable for patients to try to self-administer Vivitrol via injection. The healthcare worker will get the medication ready and give it, and they can observe for possible reactions.

It is essential to keep scheduled appointments, as the medication is intended to ensure continuous treatment between injections.

Who should not receive Vivitrol?

Do not take Vivitrol if you:

• are utilizing or are physically reliant on medications that contain opioids or illicit opioids. Refer to the section titled “Important information” above.

Before starting Vivitrol treatment, your healthcare provider may administer a small injection of a medication called naloxone to determine whether you have a physical dependence on opioid-containing medications or opioid street drugs. This procedure is known as a naloxone challenge test. If, as a result, symptoms of opioid withdrawal occur after the test, Vivitrol treatment should not be initiated at that time. Instead, after you have stopped using opioids for an appropriate period, your healthcare provider may conduct the test again. In this way, the test can help determine whether it is safe for you to begin Vivitrol treatment.

• are experiencing symptoms of opioid withdrawal. When you regularly use opioid-containing medications or illicit opioids and then cease use, you may experience withdrawal symptoms.
  Signs of opioid withdrawal can involve:
• anxiety
• sleeplessness
• yawning
• fever
• sweating
• teary eyes
• runny nose
• goose bumps
• shakiness
• hot or cold flushes
• muscle aches
• muscle twitches
• restlessness
• nausea and vomiting
• diarrhea
• stomach cramps

What should I tell my doctor before receiving Vivitrol?

Before you receive Vivitrol, tell your healthcare provider if you:

• have liver problems
• use or abuse street (illegal) drugs
• have hemophilia or other bleeding problems
• have kidney problems
• have any other medical conditions

How should I receive Vivitrol?

• Vivitrol is injected by a healthcare provider, about 1 time each month.
• Vivitrol must be injected by a healthcare provider. Do not attempt to inject yourself with this medication. Serious reactions, some that may require hospitalization, might happen.

• Vivitrol is given as an injection into a muscle in your buttocks using a special needle that comes with it.
• After Vivitrol is injected, it lasts for a month and it cannot be removed from the body.

When you require medical treatment, make sure to inform the healthcare provider treating you that you are receiving Vivitrol injections and specify the date of your last dose. This is crucial as this medication can prevent the effects of opioid-based medicines that may be prescribed to you for pain, coughs, colds, or diarrhea.

Always carry written details about this medication you are taking to notify healthcare professionals, enabling them to provide you with appropriate treatment in case of an emergency. Consult your healthcare provider about how to obtain a wallet card to carry with you.
