Food allergies are a common and potentially life-threatening medical condition. Nearly 30,000 emergency room visits occur every year in the United States as a result of food allergies, and it is estimated that 150 people die from their food allergies every year. As a result, it is very important that a person is prepared to treat an allergic reaction from accidentally eating the culprit food.
Recent studies show that up to 25% of people of with allergic reactions to foods require a second dose of epinephrine, especially those with reactions to peanuts and treenuts. So, I recommend that people with severe food allergies carry at least 2 Epi-Pens in case an accidental food exposure results in an allergic reaction.
Alternatively, a Twin-Ject device offers two doses of epinephrine in one device; this product may be a better choice for those people at risk for severe reactions from their food allergies.
Check with your doctor for instructions on when and if a second dose of epinephrine should be used for severe allergic reactions. Your doctor will likely discuss possible scenarios that may require a second dose of epinephrine. These may include severe reactions that continue to worsen despite the first dose of epinephrine, as well as reactions that don't improve within 5 to 15 minutes after the first dose of epinephrine.
