Injectafer and Vivitrol

• Generic Name: ferric carboxymaltose

• Other Brand Names: Injectafer

Injectafer (ferric carboxymaltose) is an iron replacement product. You normally get iron from the foods you eat. Iron helps your body produce red blood cells that carry oxygen through your blood to tissues and organs.

Injectafer is used in adults to treat iron deficiency anemia (a lack of red blood cells caused by having too little iron in the body).

Injectafer is usually given after oral (taken by mouth) iron replacement medicines have been tried without success.

Vivitrol (naltrexone) 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. Vivitrol is used as part of a treatment program for drug or alcohol dependence.

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

Vivitrol injection is also used to treat alcoholism by reducing your urge to drink alcohol. This may help you drink less or stop drinking altogether. Naltrexone will not decrease the effects of alcohol you recently consumed. You should not be drinking at the time you receive your first Vivitrol injection.

Naltrexone is not a cure for drug addiction or alcoholism.
