Epinephrine: Uses, Side Effect

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.

Epinephrine injection 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 injection is for use in adults and children who weigh at least 16.5
pounds (7.5 kilograms).

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