To reduce the risk of withdrawal symptoms, patients should wait at least 7 days after their last use of short-acting opioids and 10 to 14 days for long-acting opioids, before starting naltrexone. Patients taking naltrexone should not use any other opioids or illicit drugs; drink alcohol; or take sedatives, tranquilizers, or other drugs. Patients should notify their practitioner about all medications they are currently taking as well as any changes in medications while being treated with naltrexone.
Patients on naltrexone, who discontinue use or relapse after a period of abstinence, may have a reduced tolerance to opioids. Therefore, taking the same, or even lower doses of opioids used in the past can cause life-threatening consequences. When starting naltrexone for AUD, patients must not be physically dependent on alcohol or other substances. To avoid strong side effects such as nausea and vomiting, practitioners typically wait until after the alcohol detox process before administering naltrexone.
Naltrexone binds to the endorphin receptors in the body, and blocks the effects and feelings of alcohol. Naltrexone reduces alcohol cravings and the amount of alcohol consumed. Once a patient stops drinking, taking naltrexone helps patients maintain their sobriety. Naltrexone MAT treatment lasts for three to four months. Practitioners should continue to monitor patients who are no longer taking naltrexone. Patients should talk to their practitioner before starting treatment with naltrexone about the following situations:.
These are not all the side effects of naltrexone. For more information patients should talk to their practitioner or pharmacist.
Patients should tell their practitioner about any side effects that are bothersome, or do not go away. Learn about other MAT medications. Dispose of unused naltrexone safely.

How Naltrexone Works Naltrexone is not an opioid, is not addictive, and does not cause withdrawal symptoms with stop of use.
It have always provided methadone maintenance to pregnant inmates to protect the fetus from withdrawal. Newer programs include Vivitrol injections for inmates being released and most recently oral naltrexone for select new intakes with short minimums who will be admitted to one of our Opioid Use Disorder Therapeutic Communities OUDTC. Once the Pilot Program concludes, it will be rolled out gradually throughout other institutions. Suboxone and oral naltrexone will be available immediately and will also be offered to those on methadone until it can be added at a later date.
The following medications are approved by the FDA for use in opioid addiction treatment in conjunction with psychosocial therapy:. Methadone - Methadone, a synthetic opioid, is an agonist that mitigates opioid withdrawal symptoms and, at higher doses, blocks the effects of heroin and other drugs containing opiates. Maintenance of opioid addiction treatment with methadone is approved "in conjunction with appropriate social and medical services.
Buprenorphine - Buprenorphine, approved by the FDA in to treat opioid dependence, is a partial opioid agonist that, when dosed appropriately, suppresses withdrawal symptoms. Although buprenorphine can produce opioid agonist effects and side effects, such as euphoria and respiratory depression, its maximal effects are generally milder than those of full agonists like heroin and methadone.
Physicians are permitted to distribute buprenorphine at intensive outpatient treatment programs that are authorized to provide methadone if providers are trained in its use. Additionally, a special program has been established so that buprenorphine can be prescribed by physicians in office settings and dispensed by pharmacists.
In order to prescribe this medication, physicians must complete a training course and receive a waiver granted by the DEA. Buprenorphine was tested in clinical trials for addiction treatment in the United States both by itself and in combination with naloxone, a drug used to counter the effects of an overdose of opiates such as heroin or morphine. Formulations approved for drug abuse treatment are intended to be taken sublingually placed under the tongue and allowed to dissolve.
When taken this way, the naloxone has little effect. This combination formulation may deter abuse through injecting because abusers are motivated to avoid unpleasant withdrawal symptoms. Naltrexone - Naltrexone is a non-addictive antagonist used in the treatment of alcohol and opioid dependence. The medication blocks opioid receptors so they cannot be activated. This "blockade" action, combined with naltrexone's ability to bind to opioid receptors even in the presence of other opioids, helps keep abused drugs from exerting their effects when patients have taken or have been administered naltrexone.
As an antagonist, naltrexone does not mimic the effects of opioids. Rather, it simply blocks opioid receptor sites so that other substances present in a patient's system cannot bind to them. If a patient who has been administered naltrexone attempts to continue taking opioids, he or she will be unable to feel any of the opioid's effects due to naltrexone's blocking action.
The FDA approved this medication for use in people with opioid use disorders to prevent relapse. Naltrexone should be used only in patients who have been detoxified from opioids and have been opioid free for 7—10 days. Naltrexone is non-narcotic and non-addictive; however, as with other medications that interact with the opioid receptors, there is a risk of overdose if a patient who is being treated with naltrexone misses a dose and takes an opioid, or if the patient takes large quantities of opioids in an attempt to "break the blockade.
