How does this medication work? What will it do for me?
Epinephrine belongs to a family of medications called sympathomimetics. These medications resemble chemicals that are normally found in our bodies and are released during stressful situations, such as when we are scared, anxious, or angry.
Epinephrine is used for the emergency treatment of severe allergic reactions (anaphylaxis) to insect bites, insect stings, food, medication, as well as other allergens (e.g., latex). During a severe allergic reaction, blood pressure can become dangerously low, breathing can become difficult, and the face and throat can swell. Others signs and symptoms can include hives, flushing, fast heart rate, paleness, weakness, dizziness, stomach cramps, nausea, vomiting, and diarrhea. Epinephrine works to reverse these effects.
This medication may be available under multiple brand names and/or in several different forms.

How should I use this medication?
The recommended dose of epinephrine is based on your body weight, your risk of experiencing a serious allergic reaction, and your ability to tolerate the medication. The usual dose for children and adults who weigh 30 kg or more is 0.3 mg. For adults and children who weigh 15 kg to 30 kg, the dose is 0.15 mg. For children who weigh less than 15 kg, other forms of epinephrine may be prescribed.
The medication is injected into the thigh with use of a special automatic device that resembles a small case. To use the autoinjector, first remove it from the outer case. Activate the injector by removing the red safety guard. Then, jab the black end against the thigh and hold it there for five seconds. This will activate the plunger and the needle will be pushed into the thigh muscle to inject a dose of epinephrine. The injector will make a distinct sound (click and hiss) when you press it against your leg. There will be some solution remaining in the injector after injection, however the injection is complete. The voice instruction system will say "ALLERJECT has been used" and the lights will blink red. Seek immediate medical attention at the same time. If your symptoms have not improved within 10 minutes, use another dose if you have a second autoinjector.
It is important to use this medication exactly as prescribed by your doctor. It is also important to know how to use the autoinjector properly. If you are not sure, ask your doctor, nurse, or pharmacist for a demonstration.
Many things can affect the dose of a medication that a person needs, such as body weight, other medical conditions, and other medications.
