How serious can an aspirin allergy get?

Aspirin rarely produces an extremely serious reaction in those who are allergic to it. The symptoms are usually very mild and generally disappear in a couple of hours. However, in some rare cases aspirin has also been known to produce extremely reactions. It is usually the immune system which is the culprit behind the scene and acts adversely to sometimes produce life threatening conditions. In many cases it is observed that patients who are extremely sensitive to aspirin produce serious symptoms. For example, severe asthma attacks are a serious result of aspirin allergy.

It might also lead to dangerous reactions in patients with anaphylaxis, hives, and skin diseases. These people should exercise extra caution to avoid aspirin as well as other drugs and medications which have aspirin as a component. In serious cases, aspirin allergy can cause adverse skin reactions like inflammation, excessive swelling and hives. It can also lead to respiratory problems like difficulty in breathing, rhinitis and asthma attacks. Other serious reactions which might occur in allergic patients on exposure to aspirin are bleeding, upset stomach, nausea and related symptoms like vomiting, coughing, wheezing, shortness of breath, diarrhea and sometimes some gastrointestinal problems as well.
