Frequently asked questions about naltrexone

What is naltrexone?

Naltrexone is a prescription medication indicated to help individuals people who have stopped drinking alcohol or using narcotics. Naltrexone is not a cure for alcohol or drug addiction. Instead, it works in tandem with other forms of treatment like therapy and support groups to help recovery easier for individuals dealing with alcohol and drug dependence. Naltrexone is not recommended for individuals who still drink alcohol or use drugs. It is intended to aid those who are staying drug or alcohol-free.

What is naltrexone used to treat?

Naltrexone is indicated for use as a treatment for alcohol and narcotic dependence. Naltrexone is not recommended for individuals who still drink or use drugs. Instead, it is intended to help individuals who are undergoing other forms of treatment for drug and alcohol dependence – such as cognitive behavioral therapy and support groups – to suppress cravings and prevent relapse.

It is important to note that naltrexone is not a cure for substance dependency, nor will it be prescribed as the lone form of treatment for these conditions. It is meant to be used in tandem with the other forms of care listed above as a preventative measure against relapse.

How does naltrexone work?

Naltrexone is classified as an opiate antagonist, a family of drugs that block the effects of feeling “high” or the pleasurable feeling of drunkenness. Opiate antagonists do this by binding to opiate receptors in the brain. Essentially, they block these receptors from responding to opiates and endorphins. By blocking these impulses, opiate antagonists reduce the craving to get “high”.

Opiate antagonists like naltrexone do not cause any sort of physical or mental impairment. These drugs do not reproduce that “high” feeling that comes with drinking or using narcotics, nor do they cause physical or mental dependence. If anything, naltrexone will produce withdrawal symptoms in patients who have a physical dependence on alcohol or narcotic use.

By stifling cravings – which, in turn, can prevent relapse – naltrexone works alongside cognitive behavioral therapy (CBT) and support groups to help individuals recovering from alcohol and drug dependency. Naltrexone is not prescribed as a standalone treatment or “cure” for these conditions. Instead, it acts as a supplement to other therapeutic measures to aid recovery.

What are the common side effects of naltrexone?

Naltrexone has been shown to cause some mild side effects. Clinical studies have shown that only about 5% of people who take this medication experience any reactions. If these adverse effects do not go away within a few days, talk to your health care provider.


Common side effects include:

  • Nausea/ vomiting
  • Diarrhea
  • Constipation
  • Stomach Pain
  • Headache
  • Dizziness
  • Insomnia
  • Nervousness
  • Fatigue
  • Anxiety
  • Bone and joint pain

This is not a complete list of possible adverse effects. If you experience any severe vomiting, confusion, or dizziness, seek medical attention immediately.

Additionally, do not use naltrexone if you are currently using narcotic drugs. Your doctor will tell you not to take naltrexone if you have taken an opioid narcotic within the last 7-10 days. Before taking naltrexone, talk to your doctor about any medication or narcotic drugs you are currently taking.

Do not increase your dosage or discontinue the use of naltrexone without speaking to your doctor first.

What is the typical starting dose of naltrexone?

As a preventative measure against relapse in those dealing with alcohol dependence, naltrexone is prescribed as a 50 mg tablet meant to be taken once a day. This course will usually continue for up to 12 weeks.

As a preventative measure for those dealing with narcotic dependence, naltrexone is usually prescribed at a starting dose of 25 mg to be taken once daily. This dosage may increase to 50 mg/ day depending on whether or not the medication produces withdrawal symptoms in the patient.

Talk to your doctor before discontinuing the use of naltrexone, even if you begin to feel better. Do not increase your dosage of naltrexone without speaking to your doctor first.
