What symptoms would be indicative of a true allergic reaction to Motrin?

A true allergic reaction to Motrin, which is a nonsteroidal anti-inflammatory drug (NSAID), can manifest with various symptoms. Dyspnea, or difficulty breathing, is a critical sign that may indicate an anaphylactic response. This type of reaction can occur with certain medications, including NSAIDs, and can lead to airway constriction, causing the patient to experience shortness of breath or wheezing.

While swelling, rash, and itching are also possible manifestations of an allergic reaction, they do not reflect the severity associated with dyspnea. Swelling (such as angioedema), urticarial rashes, and itching can occur but typically indicate less severe reactions compared to respiratory distress. Therefore, dyspnea represents a more serious and acute allergic response that merits immediate medical attention and potential intervention.
