What should you know about epipen adrenaline auto injector?

Adrenaline supports the body's response during anaphylaxis by helping open narrowed airways and supporting blood pressure. Anaphylaxis may cause swelling of the lips or tongue, breathing difficulty, wheezing, widespread hives, vomiting, faintness or sudden collapse. Food Allergy is one possible trigger, but medicines, insect stings and other exposures can also cause a severe reaction.

The device is designed for use through clothing on the outer mid-thigh. It is prescribed in a strength suited to the person using it, so never swap devices between people or rely on an expired or damaged injector.

Use the injector as soon as anaphylaxis is suspected, following its label and your clinician's training. Call emergency services immediately, state that anaphylaxis is suspected, and keep the person lying down with legs raised when possible. If breathing is difficult, allow a comfortable sitting position; do not let them stand or walk suddenly. A second device may be needed if symptoms continue or return, but follow the emergency operator's advice. Carry the injector and an allergy action plan, and check its expiry and condition regularly.

Anaphylaxis is an emergency. Use the injector for sudden breathing or circulation problems, throat or tongue swelling, faintness, or a rapidly worsening allergic reaction, then call emergency services. Hospital observation is needed because symptoms can return after an initial improvement. If the person becomes unresponsive and is not breathing normally, begin resuscitation if trained and follow the operator's instructions.

When should I use my injector rather than waiting for more symptoms? Which device strength is prescribed for me? Should I carry more than one? Can you demonstrate the technique and help me make an allergy action plan?
