Faslodex and ReVia

• Generic Name: fulvestrant
• Dosage Forms: injection
• Other Brand Names: Faslodex

Faslodex (fulvestrant) is an anti-estrogen medication. It works by blocking the actions of estrogen in the body. Certain types of breast cancer use estrogen to grow and multiply in the body.

Faslodex is used in postmenopausal women with hormone-related breast cancer that is advanced or has spread to other parts of the body (metastatic).

Faslodex is used alone or in combination with another medicine called ribociclib (Kisqali) to treat HR-positive, HER2-negative breast cancer in:

• women with no prior treatment; or

• women whose cancer has progressed after treatment with anti-estrogen medication.

Faslodex is used in combination with palbociclib (Ibrance) or abemaciclib (Verzenio) when the cancer has progressed after treatment with anti-estrogen medication.

• Generic Name: naltrexone
• Dosage Forms: tablet, film coated
• Other Brand Names: ReVia, Depade, Vivitrol

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.
