Revia is an anti-addictive medication used to block the effects of opiates and promote the discontinuation of their abuse. This medication may also be used to treat alcohol dependence.

Naltrexone is an opioid receptor antagonist that binds to opiate receptors where opiate drugs produce their euphoric effects. By binding to these receptors, Revia blocks the effects produced by your natural opioids as well as opiate drugs. Opioids naturally occur in your brain and may play a role in alcohol addiction. Revia may help prevent people from drinking thanks to its effects on your opioid receptors.

Uses and Dosage

The dose of Revia that is prescribed will vary depending on the individual and addiction being treated. Follow all your doctor’s instructions and read package labels carefully to ensure the best results during treatment with naltrexone.

  • Swallow tablet whole with a full glass of water
  • Take with food if the doses cause stomach upset
  • To treat alcohol dependence, most adults take 50mg once daily
  • For opioid dependence, most adults start by taking 25mg before increasing to 50mg daily
  • You may need to use Revia for 3 months or longer
  • Do not stop using this medication without speaking with your doctor
  • Your doctor will administer a test to ensure that you do not have any opiate drugs in your system before prescribing Revia
  • Wait at least 7 to 10 days after stopping opiate drugs before taking Revia

Side Effects

Revia may cause some side effects to develop while inhibiting the opioid receptors in your brain. Speak with your doctor if you have any questions regarding any symptoms that you might encounter when taking naltrexone.

Common Revia side effects:

  • Nausea, vomiting, stomach pain
  • Headache, dizziness, drowsiness
  • Anxiousness, nervousness
  • Insomnia
  • Muscle or joint pain

Serious Side Effects

Some more serious adverse reactions may occur when taking naltrexone. Stop using Revia and contact your doctor if you notice any of the following side effects:

  • Severe nausea, vomiting, or diarrhea
  • Confusion, mood changes, crying, hallucinations
  • Depression, suicidal thoughts

Taking high doses of naltrexone may cause damage to your liver. Contact your doctor immediately if you develop right-sided upper stomach pain, vomiting, loss of appetite, dark urine, clay-coloured stools, jaundice.

Allergic Reactions

Do not take Revia if you are allergic to naltrexone or any of the other listed tablet ingredients. If you develop signs of an allergic reaction, stop using this medication and call your doctor right away.

Revia allergy symptoms may include:

  • Hives
  • Difficulty breathing
  • Swelling of face, lips, tongue, or throat


Do not take Revia if you have liver failure or acute hepatitis.

Do not use Revia if you have taken an opiate drug within the last 7 or 10 days or if you are experiencing opioid withdrawal symptoms.

To ensure your safety when taking naltrexone, tell your doctor if you have ever had any of the following:

  • Liver disease
  • Kidney disease

Do not take any opiate drugs during treatment with Naltrexone. Revia blocks the effects of opioids, but large doses can still lead to serious problems such as trouble breathing which may results in death.

Revia may cause harm to your liver if taken in high doses. Stop using the medication and contact your doctor if you develop any of the following: right-sided upper stomach pain, vomiting, loss of appetite, dark urine, clay-coloured stools, or jaundice.

Do not drink alcohol while taking Revia because this can lead to serious liver damage. Stop using Revia and call your doctor if you consume alcohol and develop abdominal pain that lasts for a few days, white bowel movements, dark urine, or yellowing eyes.

Do not take Revia in order to drive or operate equipment after having drank alcohol. The medication will not inhibit the effects of alcohol and you will still become intoxicated.

Be careful when driving or performing hazardous tasks while taking Revia because it may cause you to become dizzy or drowsy.

Ask your doctor before taking any other medications during your treatment with Revia.

Some drugs may interact with naltrexone and cause unwanted reactions. Tell your doctor about all the medications that you use, including over the counter medicines, but especially any of the following:

  • Thioridizine
  • Disulfiram
  • Cough or cold medicine
  • Diarrhea medication
  • Certain pain killers

Tell your doctor if you are pregnant or breastfeeding before taking Revia. It is unclear how naltrexone may affect your unborn baby, but if you use opioid drugs while pregnant your baby could develop life-threatening withdrawal symptoms after birth.

What should I avoid while taking Revia?

You should avoid using any opioid drugs during treatment with Revia. Naltrexone will block the effects of opioid drugs such as feelings of euphoria but will not prevent them from causing life-threatening side effects such as trouble breathing which could lead to death. When taking Revia, you should also avoid drinking alcohol to limit liver damage.

Do you take Revia with or without food?

Whether you take Revia with or without food will not affect the drug’s efficacy on inhibiting your brain’s opioid receptors. However, a common side effect of naltrexone that is reported is an upset stomach. Taking your dose of Revia with food could help counteract this adverse effect. Follow all your doctor’s instructions for administration to ensure the best therapeutic results during treatment.
