How EpiPen® works
- Relaxing the muscles in your airways to make breathing easier
- Helping to reverse the rapid and dangerous decrease in blood pressure
- Relaxing the muscles in the stomach, intestines and bladder
Even after epinephrine has been administered, immediate emergency medical treatment is still necessary. You will need professional care to determine whether additional epinephrine, steroids, antihistamines or other treatments are required.
A second reaction can occur up to 38 hours after your initial reaction, so you will need to remain under medical supervision for at least 4 hours.
Once you are discharged from the hospital, you should have an EpiPen® Auto-Injector available. You should also stay close to a healthcare facility or be able to call 911 for the next 48 hours.
Consider having more than one EpiPen® on hand in your home and when going out.
