Is naltrexone toxic to liver?
Precautions listed in naltrexone’s product information include saying it may cause hepatocellular injury when given in excessive doses, and its use in patients with active liver disease must be carefully considered in light of its hepatotoxic effects.
Is there a way to reverse Vivitrol?
Although VIVITROL is a potent antagonist with a prolonged pharmacological effect, the blockade produced by VIVITROL is surmountable. The plasma concentration of exogenous opioids attained immediately following their acute administration may be sufficient to overcome the competitive receptor blockade.
How long should a patient be on Vivitrol?
Most medical professionals will recommend that Vivitrol be used for at least one year. When speaking to a physician about Vivitrol injections within a medication assisted treatment program, it can be beneficial to also discuss how long you might remain on Vivitrol.
When taking certain medications, whether they’re prescription or over-the-counter, it’s essential to know the risks, side effects, and potential interactions with other drugs or alcohol. Many medications do have interactions with alcohol or are generally unsafe to combine with drinking.
Does drinking on naltrexone make you tired?
Bottom Line –
Naltrexone blocks the pleasurable effects and feelings of intoxication (the “buzz”) from alcohol consumption. By breaking the link between pleasure and drinking, your cravings for alcohol over time may decrease. This can help you to stay sober. Naltrexone will not prevent you from becoming impaired while drinking alcohol. Do not use naltrexone so that you can drive or perform other activities under the influence of alcohol. You need to have stopped opioid (narcotic) use for at least 7 to 14 days before starting treatment with naltrexone to help prevent withdrawal symptoms. Discuss this with your doctor.
This is not all the information you need to know about naltrexone for safe and effective use. Review the full naltrexone prescribing information and discuss this drug with your doctor or other health care provider. References

Can vivitrol cause liver failure?
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, or have any other medical conditions.

Talk to your healthcare provider about whether you will breastfeed or take VIVITROL. You should not do both.
Tell your healthcare provider about all the medicines you take, including prescription and non-prescription medicines, vitamins, and herbal supplements. Especially tell your healthcare provider if you take any opioid-containing medicines for pain, cough or colds, or diarrhea.

Do you take naltrexone for life?
The Sinclair Method Frequently Asked Questions Naltrexone is a non-addictive medication that blocks the opiate receptors but does not activate any of the usual euphoria or high one receives from addictive drugs. TSM patients are highly urged to take the medication before drinking for the rest of their life, however if they choose to stop drinking and stop the naltrexone, they will not have withdrawals and the only risk would be a potential relapse if they start to drink again without taking the naltrexone first.

What is the success rate of naltrexone for alcohol?
CLINICAL EVIDENCE – A number of randomized, controlled trials have evaluated the effectiveness of naltrexone in the management of alcohol dependence with the use of a variety of therapeutic end points. Many of these studies have included some form of behavioral intervention as an adjunct to medication.
Several of the largest such trials were multisite studies performed in the United States. A large clinical trial sponsored by the Department of Veterans Affairs 19 enrolled 627 veterans with chronic, severe alcohol dependence. Naltrexone (at a dose of 50 mg daily), given for either 3 months or 12 months, was not significantly better than placebo in increasing the number of days until relapse or in reducing the percentage of drinking days or the number of drinks per drinking day.
On the other hand, the Combined Pharmacotherapies and Behavioral Interventions (COMBINE) study ( ClinicalTrials.gov number, NCT00006206 ), 20 which was conducted at 11 academic sites across the United States, enrolled 1383 patients with alcohol dependence and at least 4 days of abstinence.
This trial showed that in patients who received medical treatment but not behavioral therapy, naltrexone (at a dose of 100 mg daily), given for 16 weeks, was more efficacious than placebo in increasing the percentage of days of abstinence (80.6% vs.75.1%) and in reducing the risk of a heavy-drinking day (66.2% vs.73.1%).
In the COMBINE study, investigators used an end point called “good clinical outcome,” which was defined as no more than 2 days of heavy drinking per week and drinking at or below a safe limit (14 drinks per week for men and 11 drinks per week for women) without significant alcohol-related problems during the last 8 weeks of the 16-week trial.
In the group that received naltrexone, there was an absolute increase of approximately 15% in good clinical outcomes (73.7%, as compared with 58.2% in the placebo group; odds ratio in the naltrexone group, 2.16; 95% confidence interval, 1.46 to 3.20). A few meta-analyses and a Cochrane review (all conducted before the publication of the COMBINE study) have systematically evaluated the accumulated data on the efficacy of naltrexone.21 – 25 Typically, the studies have shown that oral naltrexone was superior to placebo in preventing relapse to heavy drinking after an initial abstinence period and in increasing the percentage of abstinence days.
A long-acting, injectable form of naltrexone has also been evaluated in a large, multisite, randomized, controlled trial.26 In this study, persons with alcoholism were randomly assigned to receive one of two doses of intramuscular naltrexone (190 mg or 380 mg) or matching placebo.
Does naltrexone make you nauseous if you drink?
The Bottom Line: Using Naltrexone to Stop Drinking – It’s incredibly difficult to quit drinking. Alcohol is ubiquitous in our society. If you’ve tried to quit drinking on your own and can’t, naltrexone can help. Here are the facts about drinking while on Naltrexone:
Naltrexone is different from several older medications that were once used to treat alcohol use disorder by making you feel physically sick if you drank while taking them, such as Disulfiram.
It is safe to drink while on Naltrexone, and many people do, at least at first, as they work on slowly reducing the amount they drink.
If you do drink while on Naltrexone, the “intoxicating” effects may be slightly less, but you can still “get drunk” if you continue to drink heavily while on Suboxone.
If you do drink while on Naltrexone, you will not cause yourself harm or make yourself feel sick.
If you think naltrexone may be right for you, talk with your doctor. You’ll need a prescription to get started.
