What is the incidence of anaphylaxis associated with omalizumab?

The incidence of anaphylaxis associated with omalizumab, a monoclonal antibody used primarily in the treatment of allergic asthma and chronic spontaneous urticaria, has been reported in clinical studies and post-marketing surveillance. Current data indicates that the incidence is approximately 0.20%.

This incidence level is particularly important for healthcare providers to consider when prescribing omalizumab, as anaphylaxis is a serious allergic reaction that requires immediate attention. While the risk may seem low, it is still significant enough to warrant caution, especially in patients with a history of severe allergies.

This understanding aligns with the healthcare community's recommendations for monitoring patients who receive omalizumab, particularly during the initial doses. By recognizing this potential risk, clinicians can provide better patient education, ensuring that patients understand the signs and symptoms of anaphylaxis and know how to respond if they experience a severe allergic reaction.

The other options suggest lower rates of incidence, which do not reflect the currently accepted statistics based on available data, thus they do not accurately represent the reported frequency of anaphylactic reactions associated with omalizumab.
