Action Mechanism

The action mechanism of Naltrexone in treating chronic alcoholism is poorly understood. However, its involvement in the endogenous opioid system has been well documented. Naltrexone is an opioid receptor antagonist, which binds to such opioid receptors and blocks the effects of opioids. Opioid antagonists have also been found effective at reducing alcohol consumption in clinical studies.


  • For alcohol abuse treatment, doctors advise Naltrexone 50 mg once daily for up to 12 weeks.
  • For the treatment of opioid addiction, Naltrexone 25 mg is recommended initially. Once you experience no withdrawal symptoms after a few days of treatment, you can start 50 mg a day.
  • Take this medicine orally with or without food, once daily, or as recommended by your doctor. You can take it with food or antacids to prevent an upset stomach.
  • It is important to undergo a urine test regularly while using Naltrexone for recent opiate drug abuse. Do not use any opioids for at least a week before starting this drug.
  • Make sure you take this medication exactly as recommended. Do not increase or decrease your dose. Do not stop taking it without your physician’s approval.
  • Be sure to use Naltrexone regularly to reap the benefits of the drug. Take the drug at the same time every day without skipping or missing the dose.


  • Before using Naltrexone, tell your doctor if you are allergic to any opioid antagonists, including Naltrexone.
  • Before using this opioid addiction medication, tell your doctor about your medical history, especially if you have kidney disease or liver disease.
  • People who have been advised to take this drug should carry medical identification stating that you have been using it so that doctors can give appropriate treatment in an emergency.
  • Before undergoing any surgery or medical treatment, tell your physician that you have been taking Naltrexone for opioid addiction or alcohol abuse.
  • During pregnancy and breast-feeding, Naltrexone should be used only when your doctor recommends.

Side Effects

  • Nausea
  • Headache
  • Dizziness
  • Anxiety
  • Tiredness
  • Trouble sleeping

Some people may experience mild opiate withdrawal symptoms such as abdominal pain or cramps, anxiousness, restlessness, joint pain, muscle pains, or runny nose. If any of these side effects persist or aggravate, get immediate medical attention.


  • Naltrexone may make you a bit dizzy or drowsy so avoid alcohol or marijuana (cannabis), which can also make you dizzy.
  • Since the drug causes drowsiness, stay away from driving, using machinery, or doing anything that needs your attention. Avoid alcohol during treatment.
  • Do not overdose with Naltrexone. If you overdose and experience symptoms such as trouble breathing or fainting, visit your nearest ER. Do not share Naltrexone with other people.
  • You may have to undergo a few blood works periodically to monitor your treatment progress or check for any side effects. Check with your doctor for more information on lab works.
  • Check with your doctor and tell him about the medications you have been taking. That’s because Naltrexone interacts with drugs like dextromethorphan, diarrhea medications, disulfiram, opioid pain relievers, and certain cough medications.


Customer's Review

Average Rating : 4 / 5

  • I have been using naltrexone for my alcohol dependence issue. Initially, it did not work much, but on regular use, I gradually limited my drinking habits. I prefer buying naltrexone online through this website.
