Anaphylaxis is a severe and potentially life-threatening allergic reaction that can occur rapidly after exposure to an allergen, such as medication. Severe difficulty in breathing and swelling are hallmark indicators of anaphylaxis. The swelling often occurs in the throat or tongue, leading to constricted airways, which significantly impairs breathing. This reaction demands immediate medical attention as it can escalate quickly, potentially resulting in respiratory failure and shock.

Other symptoms like a rash on the arm, mild nausea, or temporary dizziness may indicate less severe allergic reactions or side effects that do not constitute a full anaphylactic response. While these symptoms should not be ignored, they do not reflect the severity or urgency associated with anaphylactic reactions, which primarily involve respiratory distress and significant swelling. Thus, the presence of severe difficulty breathing and swelling is critical for recognizing a potential anaphylactic reaction.
