Epinephrine is a chemical that narrows blood vessels and opens airways in the lungs. These effects can reverse severe low blood pressure, wheezing, severe skin itching, hives, and other symptoms of an allergic reaction.

EPIsnap is used to treat severe allergic reactions (anaphylaxis) to insect stings or bites, foods, drugs, and other allergens.

Epinephrine auto-injectors may be kept on hand for self-injection by a person with a history of severe allergic reaction.

Epinephrine is also used to treat exercise-induced anaphylaxis, or to treat low blood pressure that is caused by septic shock.

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.
