Naltrexone is a medication primarily used to treat alcohol use disorder and opioid use disorder. This prescription drug is a crucial part of a comprehensive recovery program. Such programs should include counseling and social support. Naltrexone helps people remain abstinent by reducing cravings. It also blocks the pleasurable effects of alcohol and opioids. This makes relapse less likely to occur. It is not a cure for addiction but a tool to support long-term recovery.
Naltrexone works as an opioid antagonist in the brain. This means it blocks the euphoric and sedative effects of opioids like heroin, morphine, and codeine. By binding to opioid receptors without activating them, it prevents these substances from producing a “high.” For alcohol dependence, it works by reducing the rewarding effects of drinking. This action helps to decrease cravings for alcohol over time. The medication helps break the cycle of addiction by removing the positive reinforcement associated with substance use.
Naltrexone is for adults who are motivated to recover from alcohol or opioid dependence. It is intended for patients who have already stopped using these substances. For opioid addiction, a person must be opioid-free for at least 7-10 days before starting. This is to prevent sudden and severe withdrawal symptoms. The medication is best used by individuals who are also receiving counseling or therapy. It serves as an extra layer of support for those committed to sobriety.
Naltrexone is typically administered as an oral tablet, usually taken once per day. The exact dosage and treatment duration depend on the condition being treated and your doctor’s recommendation. It is very important to follow your healthcare provider’s instructions carefully. Do not change your dose without consulting your doctor. The medication can be taken with or without food. If it causes stomach upset, taking it with a meal may help. Consistent use is key to its effectiveness in preventing relapse.
Naltrexone may cause some side effects, though not everyone experiences them. Common side effects often improve as your body adjusts to the medication. These can include nausea, headache, dizziness, anxiety, and difficulty sleeping. Less common but more serious side effects may occur. These include liver damage, severe skin reactions, and mood changes like depression. You should contact your doctor immediately if you experience severe abdominal pain, dark urine, or thoughts of self-harm. An allergic reaction is also possible.

Naltrexone is primarily indicated for the treatment of:
Naltrexone will block the euphoric and pain-relieving effects of opioids if you use them. This is because it is an opioid antagonist. Taking opioids will not produce the "high" you expect. Attempting to overcome this blockade by taking large amounts of opioids is extremely dangerous. It can lead to serious injury, coma, or even death from overdose. You must not use opioids while on Naltrexone.
Naltrexone begins working to block opioid receptors within about one hour of taking an oral dose. Its effects on reducing alcohol cravings may take longer to become noticeable and build over time with consistent use. For Naltrexone to be most effective, it must be used as part of a comprehensive treatment program that includes counseling and support. Consistency is key to achieving the best results.
Naltrexone is prescribed to help you reduce or stop drinking alcohol. While it does not make you sick if you drink, it reduces the rewarding, pleasurable feelings associated with alcohol consumption. The goal is to reduce your motivation to drink. Combining alcohol with Naltrexone can increase the risk of side effects like dizziness and somnolence. It is best to avoid alcohol entirely while on this medication.
Naltrexone is not an addictive substance. It is an opioid antagonist, which means it blocks the effects of opioids and does not produce any feelings of euphoria, pleasure, or pain relief. Naltrexone does not lead to physical or psychological dependence. It is a safe and effective medication used specifically to help manage and treat addictions to other substances like opioids and alcohol without creating a new dependency.
Naltrexone itself does not cause physical withdrawal when you stop taking it. However, if you take Naltrexone while you are still physically dependent on opioids, it will trigger immediate and severe withdrawal symptoms. This is why you must be completely opioid-free for 7 to 10 days before starting treatment. Always consult your doctor before discontinuing Naltrexone to discuss a plan and prevent a potential relapse.
If you miss a dose of Naltrexone, you should take it as soon as you remember. However, if it's almost time for your next scheduled dose, just skip the missed one. Do not take a double dose to make up for the one you missed. Taking extra Naltrexone will not increase its effectiveness and may increase your risk of side effects. Maintaining a consistent schedule is important for the medication to work properly.
You should discuss stopping treatment with your healthcare provider. Naltrexone itself does not cause withdrawal symptoms upon discontinuation, so it can be stopped suddenly without tapering. However, stopping the medication increases your risk of relapse to alcohol or opioid use. Your doctor can help you create a plan to safely stop the medication and provide support to help you maintain your recovery progress without it.
Naltrexone should be stored in its original container at room temperature, which is typically between 68°F and 77°F (20°C and 25°C). Keep the medication away from excess heat, direct light, and moisture. Do not store it in the bathroom, as the humidity can damage the tablets. Be sure to keep Naltrexone and all other medications out of the reach of children and pets to prevent accidental ingestion.
Naltrexone is a prescription medication and is not a substance of abuse, so it is not typically included in standard drug screening panels for employment. If a specialized test does detect Naltrexone, it will not be reported as a positive result for an illicit drug. You can simply provide proof of your prescription to the testing facility or employer if any questions arise. Always be transparent about your prescribed medications.
Naltrexone can interact with other drugs, especially any medication that contains opioids. This includes certain prescription pain relievers, cough and cold formulas, and some anti-diarrhea medicines. Taking opioids with Naltrexone will make them ineffective and can cause sudden withdrawal. Always give your doctor and pharmacist a complete list of all medications you take, including over-the-counter drugs and supplements, to avoid dangerous interactions.
Naltrexone does not treat or relieve pain. It is an opioid blocker, so it will actually interfere with the pain-relieving effects of opioid medications. If you are taking Naltrexone and need treatment for pain, you must inform your doctor. They will need to prescribe non-opioid pain relievers. In an emergency, medical personnel should be alerted that you are taking Naltrexone so they can manage your pain effectively.
Naltrexone may affect mood in some people. While it helps many, potential side effects can include anxiety, nervousness, or, in rare cases, sadness or depression. It is very important to monitor your mental health while taking this medication. If you experience any significant mood changes, feelings of hopelessness, or thoughts of harming yourself, you should contact your healthcare provider immediately to discuss your symptoms.
