Understanding Vivitrol Prescribing Information: Dosage, Administration and Effects
Vivitrol is a prescription medication used to treat alcohol and opioid dependence. It is administered as an injection and helps reduce cravings for alcohol and opioids. It works by blocking the receptors in the brain that give rise to the pleasurable effects associated with these substances. This article will provide you with a comprehensive understanding of Vivitrol prescribing information, including dosage, administration, and effects.
What is Vivitrol?
Vivitrol is a non-addictive, once-a-month injection medication for the treatment of alcohol and opioid dependence. It is prescribed to individuals who have completed detoxification and are no longer actively using these substances. The active ingredient in Vivitrol is naltrexone, which blocks the opioid receptors in the brain, preventing the pleasurable effects associated with opioids and alcohol.
Dosage and Administration
The starting dose of Vivitrol is 380 mg, administered once a month by injection into the gluteal muscle. The initial injection must be given following a negative urine screen for opioids. For patients switching from oral naltrexone, the first injection of Vivitrol should be given approximately 7-10 days after the last dose of oral naltrexone.
It is essential to check liver function tests before administering Vivitrol. If the patient’s liver function tests are abnormal, they may need to undergo further evaluation before starting Vivitrol treatment.
Effects of Vivitrol
Vivitrol reduces the pleasurable effects of alcohol and opioids, which helps individuals who are dependent on these substances maintain abstinence. Studies have shown that Vivitrol decreases the likelihood of relapse and prolongs the time to relapse in individuals who abstain from opioid use. It also reduces the frequency and severity of cravings for alcohol and opioids.
The most common side effects of Vivitrol include nausea, headache, dizziness, fatigue, and injection site reactions. These side effects are generally mild and transient and do not require discontinuation of the medication.
