Revia contains the active ingredient naltrexone. It is a prescription medication used as part of a treatment program for alcohol dependence and opioid dependence.
Revia may be used to help people with alcohol dependence reduce the risk of relapse and support continued abstinence.
It does not cause a negative physical reaction if alcohol is consumed. Instead, Revia works by reducing some of the rewarding or reinforcing effects associated with drinking.
Revia is most effective when it is used together with a broader treatment plan that may include counseling, behavioral therapy, support programs, and regular follow-up with a healthcare provider.
Revia is also used to block the effects of opioids.
It can reduce or prevent the effects of opioid drugs such as:
Before starting Revia, a person must be opioid-free for an appropriate period of time. Taking Revia while opioids are still in the body can trigger sudden and severe opioid withdrawal.
A healthcare provider will determine when it is safe to begin treatment.
Revia belongs to a class of medications called opioid antagonists.
It works by attaching to opioid receptors in the brain and blocking them. This prevents opioid drugs from activating these receptors and producing their usual effects.
The exact way Revia helps with alcohol dependence is not fully understood.
Its effect is thought to involve the body’s opioid system, which plays a role in the rewarding effects of alcohol. By blocking opioid receptors, Revia may reduce the reinforcing effects of drinking and help reduce the desire to continue drinking.
In people being treated for opioid dependence, Revia helps prevent opioids from producing their usual rewarding effects.
This blockade may help reduce the likelihood of returning to opioid use as part of an ongoing recovery program.
Revia does not treat opioid withdrawal and should not be started until the healthcare provider confirms that the patient has been opioid-free for the required period.
Revia is not intended to be used as the only treatment for alcohol or opioid dependence.
It is generally used as part of a complete treatment program that may include:
The length of treatment depends on the condition being treated, response to therapy, risk of relapse, and overall treatment plan.
Revia is an oral tablet that is usually taken once daily, with or without food, as directed by your healthcare provider.
The usual dose is 50 mg once daily. If Revia causes stomach upset, taking it with food may help.
Take Revia at about the same time each day to help you remember your dose and maintain a consistent treatment routine.
In some supervised treatment programs, a healthcare provider may use a different dosing schedule.
For example, larger doses may be given every 2 or 3 days to make clinic visits or supervised dosing more convenient.
Do not change your dosing schedule unless your healthcare provider specifically tells you to do so.
You must be opioid-free before starting Revia.
Starting Revia while opioids are still in your body can cause sudden and severe withdrawal symptoms.
Your healthcare provider may perform a urine drug test before treatment to check for recent opioid use.
In some cases, a naloxone challenge test may also be used to help determine whether opioids are still present in your body.
People who have been using short-acting opioids should generally be opioid-free for at least 7 to 10 days before starting Revia.
A longer opioid-free period may be needed after using long-acting opioids such as methadone or buprenorphine. In these situations, your healthcare provider may recommend waiting 10 to 14 days or longer, depending on your individual circumstances.
Do not start Revia until your healthcare provider confirms that it is safe to do so.
Your Revia dose may depend on:
Some patients may receive a lower test dose when treatment begins so the healthcare provider can check for signs of opioid withdrawal before giving the full dose.
Do not take more Revia, take it more often, or stop treatment without speaking with your healthcare provider.
Taking higher doses does not improve treatment and may increase the risk of side effects.
For the best results, take Revia consistently and follow the full treatment plan recommended by your healthcare provider.
Revia is usually most effective when combined with counseling, behavioral therapy, support programs, or other addiction treatment services.
If you miss a dose of Revia, take it as soon as you remember.
If it is almost time for your next scheduled dose, skip the missed dose and continue with your regular dosing schedule.
Do not take two doses at the same time or take extra Revia to make up for a missed dose.
If you are following a supervised or less-frequent dosing schedule, contact your healthcare provider or treatment program for instructions before taking a replacement dose.
Tell your healthcare provider if you return to alcohol or opioid use during treatment.
Do not try to overcome the opioid-blocking effects of Revia by taking larger amounts of opioids. This can lead to a dangerous or potentially fatal overdose.
Your tolerance to opioids may also be lower after stopping Revia, which can increase the risk of overdose if opioids are used again.
Revia (Naltrexone) is available in the following forms and strength:
Revia can cause liver injury in some patients.
Tell your healthcare provider if you have liver disease, hepatitis, abnormal liver tests, or a history of heavy alcohol use. Your healthcare provider may check your liver function before and during treatment.
Contact your healthcare provider promptly if you develop symptoms that may suggest liver problems, such as:
Revia should be stopped if signs or symptoms of acute hepatitis develop.
Do not start Revia while you are still physically dependent on opioids.
Revia can suddenly block opioid receptors and cause precipitated withdrawal, which may be severe enough to require medical treatment or hospitalization.
People who have been using short-acting opioids should generally be opioid-free for at least 7 to 10 days before starting Revia. People transitioning from methadone or buprenorphine may remain at risk of precipitated withdrawal for up to about 2 weeks.
Do not try to overcome the opioid-blocking effects of Revia by taking larger amounts of opioids.
Doing so can lead to a serious or potentially fatal overdose.
Opioid tolerance may also decrease during Revia treatment. This means that after Revia is stopped, using an opioid dose that was previously tolerated may increase the risk of overdose.
Tell your healthcare provider if you have kidney disease.
Revia and its metabolites are partly eliminated through the kidneys, so extra caution may be needed in people with kidney impairment. Your healthcare provider will determine whether treatment is appropriate and whether additional monitoring is needed.
Depression, suicidal thoughts, suicide attempts, and suicide have been reported in people taking naltrexone, although a direct cause-and-effect relationship has not been established.
Patients receiving Revia should be monitored for new or worsening depression or suicidal thinking.
Contact your healthcare provider promptly if you experience significant changes in mood, behavior, or thinking.
Do not take Revia if you have had a serious allergic reaction to naltrexone or any ingredient in the tablets.
Seek urgent medical attention if you develop symptoms such as:
Tell your healthcare provider about all prescription medications, over-the-counter products, vitamins, supplements, and herbal products you use.
This is especially important for medications that contain opioids, including some:
Revia can block the effects of opioid-containing medicines and may interfere with opioid pain treatment.
Tell surgeons, dentists, emergency healthcare providers, and other members of your healthcare team that you are taking Revia.
Because Revia blocks opioid receptors, standard opioid pain medications may not work as expected. Your healthcare team may need to use a different pain-management approach.
Tell your healthcare provider if you are pregnant, think you may be pregnant, or plan to become pregnant.
Available information about Revia use during pregnancy is limited. Your healthcare provider will weigh the potential benefits of treating alcohol or opioid dependence against any possible risks of treatment.
Do not stop Revia on your own if you become pregnant.
Tell your healthcare provider if you are breastfeeding or plan to breastfeed.
Naltrexone and its metabolite can pass into breast milk. Your healthcare provider can help determine whether Revia is appropriate based on the benefits of treatment and the potential effects on the nursing infant.
Revia may cause dizziness in some people.
Use caution when driving, operating machinery, or performing activities that require alertness until you know how Revia affects you.
No. Revia may not be suitable for everyone. Tell your healthcare provider if you have liver disease, kidney disease, a history of allergic reactions to naltrexone, or if you are currently using opioids. Revia should not be started while opioids are still in your body because it can trigger sudden and severe withdrawal. Your healthcare provider will review your medical history and current medications before deciding whether Revia is appropriate for you.
Revia can interact with certain medications. This is especially important for medicines that contain opioids, including some prescription pain medications, cough medicines, and antidiarrheal products. Revia can block the effects of opioids and may interfere with pain treatment. Tell your healthcare provider about all prescription medications, over-the-counter products, vitamins, supplements, and herbal products you use before starting Revia.
Yes. Revia can be used as part of a treatment program for opioid dependence. It works by blocking opioid receptors in the brain, which prevents opioids from producing their usual effects. This can help reduce the rewarding effects of opioid use and support relapse prevention. Before starting Revia, you must be opioid-free for the recommended period of time. Revia does not treat opioid withdrawal and should not be started until your healthcare provider confirms that it is safe.
The length of Revia treatment varies from person to person. Some people may take Revia for several months, while others may need treatment for a longer period. The appropriate duration depends on the condition being treated, response to therapy, risk of relapse, side effects, and the overall treatment plan. Your healthcare provider will monitor your progress and determine how long treatment should continue. Do not stop Revia without first discussing it with your healthcare provider.
