Discharge Instructions: Using an Autoinjector

Your healthcare provider has prescribed a medicine that you will need to inject through your skin. This is done with an autoinjector. It is a small device with a hidden needle. The needle is activated by a spring. This makes giving yourself a shot easy. It also makes it easy for someone else to give you a shot if you can’t do it yourself. There is no need to look for the best injection site or to give the shot in the buttocks or arm. Use any site on the outer side of your thigh. Be sure your family members and friends know where to give the shot.

Home care

Inject your medicine as often as advised by your healthcare provider. Follow any instructions from your healthcare provider about the medicine. To give yourself a shot:

  • Remove the safety cap from the autoinjector. This activates it.

  • Point the tip of the autoinjector at the outer side of your thigh. Jab it against your thigh for  10 seconds. This releases a spring-activated plunger that pushes the needle into the thigh muscle and gives you a dose of medicine. Massage the area where you injected the medicine for about 10 seconds.

  • Dispose of the autoinjector as instructed.

  • If your autoinjector is for emergency medicine (such as epinephrine for an allergic reaction), call 911 and get to the nearest emergency room. Don't drive yourself. Be aware that you may need a second injection if you are still having the reaction or symptoms.

Follow-up care

Follow up with your healthcare provider, or as advised.
