Important information about Revia

How does Revia work?

The active ingredient in Revia is naltrexone hydrochloride, which is an opioid antagonist. The mechanism of action involves inhibiting the body's opioid receptors. In doing so, naltrexone inhibits the rewarding effects of drinking alcohol or taking opioids. This can assist in reducing cravings for alcohol or narcotics.

How do you use Revia?

  • After using Revia, your body may become more sensitive to opioids. If you continue to use them, you might respond to lower doses of opioids than before. Using the same dose you used before may result in an overdose or death.
  • Wear a medical alert tag or carry an ID card to notify others that you use Revia.
