Introvale is a combination drug that contains female hormones that prevent ovulation (the release of an egg from an ovary). Introvale also causes changes in your cervical mucus and uterine lining, making it harder for sperm to reach the uterus and harder for a fertilized egg to attach to the uterus.

Introvale is used as contraception to prevent pregnancy.

Introvale may also be used for purposes not listed in this medication guide.

ReVia blocks the effects of opioid medication, including pain relief or feelings of well-being that can lead to opioid abuse. An opioid is sometimes called a narcotic. This medicine is used as part of a treatment program for drug or alcohol dependence.

ReVia is used to prevent relapse in people who became dependent on opioid medicine and then stopped using it. This medicine can help keep you from feeling a "need" to use the opioid.

ReVia is also used to treat alcoholism by reducing your urge to drink alcohol. This may help you drink less or stop drinking completely. This medicine will not cause you to "sober up" and will not decrease the effects of alcohol you recently consumed.

ReVia is not a cure for drug addiction or alcoholism.

ReVia may also be used for purposes not listed in this medication guide.
