KUSA - At least 15 million Americans endure food allergies, and one in every 13 children under the age of 18 deals with food allergies.
When dealing with an allergic reaction, people need a shot of epinephrine, which can be found in an auto-injector.
A new auto-injector called Auvi-Q talks its users through each step.
"In a stressful situation, it's very helpful," Registered Nurse Emily Cole said.
9NEWS Medical Expert Dr. John Torres said users don't always leave the injector in the skin for the full five seconds. He said it's because the injection hurts, and they're not breathing well.
"Having that countdown is very important," Dr. Torres said. "People don't realize that's when the medicine is being administered. You have to hold it there the whole time."
The Auvi-Q auto-injector is slightly smaller than other ones. However, it contains the same dose of epinephrine.
Epinephrine is for anaphylaxis, an allergic reaction to an antigen that causes the body to become hypersensitive.
It's should be used in life threatening situations. It's not for basic food allergies that cause slight itching.
Epinephrine contracts the blood vessels, which prevents a person's blood pressure from dropping.
It makes the heart beat a little faster. It also stops some of the chemicals being released that causes the allergic reaction.
Most pharmacies are carrying the Auvi-Q and most insurance companies are covering it.
