When it comes to food allergies and anaphylaxis, it is recommended that one be deliberate and not hesitate when using epinephrine. A form of adrenaline – epinephrine is a hormone the human body creates naturally in response to stress. When injected, epinephrine works rapidly to constrict blood vessels, which helps increase blood pressure and keep blood flowing to vital organs. (Anaphylaxis can cause a severe and life-threatening drop in blood pressure.) It also relaxes airways to improve breathing, relieves cramping in the gastrointestinal tract, decreases swelling, and helps blocks itching and hives. Epinephrine reverses symptoms and allows time to seek additional care. Side effects from epinephrine may include rapid heart rate, feeling jittery, weakness, paleness, and headache. Side effects are generally mild and go away within a few minutes. This medication is potentially life-saving and can be found through the following resources.
