If you have severe allergies, it's crucial to be prepared. Always keep two epinephrine injection kits with you and make sure they are easily accessible. If you experience any signs of anaphylaxis, such as difficulty breathing, swelling of the face or throat, rapid or weak pulse, or severe skin reactions, use the autoinjector immediately. Even if the symptoms do not seem to be related to an allergy, using the autoinjector as a precaution will not harm you. After administering the injection, call 911 or seek emergency medical help right away. Quick action can be life-saving in severe allergic reactions.
