Hello,
With the question “Can a person with anaphylaxis have an anaphylactic reaction? , the doctor would like to answer as follows:
Contrast and anesthetic drugs have different molecular structures; so there is less chance of cross-reactivity. However, the patient had experienced anaphylaxis with contrast; There is also a risk of an anaphylactic reaction to the anesthetic.
Therefore, you need to see an Allergist to determine if: Are you allergic to anesthetics, how severe the allergy is, specific treatment methods.
In addition, when you go to the doctor for examination and treatment, you need to inform the doctor that you have a history of any drug allergies, so that the doctor can offer an appropriate treatment plan.
If you still have questions about anaphylaxis, you can go to a hospital of Vinmec Health System for further examination and advice. Thank you for trusting and sending questions to Vinmec. Wishing you lots of health.
Best regards!
