An Introduction to Allergic Reactions and Colonoscopy
Most medicines are safe, although there is always the risk of having an adverse or allergic reaction during or after your
colonoscopy. This is true for all types of medicine, including anesthesia. Some examples of minor allergic reactions include:
- Itchy eyes
- Runny nose
- Skin rashes.
Some people may have a serious reaction called "anaphylaxis," which can be fatal.
There is no way for your doctor to know if you will be allergic to medicines that you have never tried. However, your healthcare team will try to find out as much information as they can to help prevent an allergic reaction during a colonoscopy test. They will ask questions about medicines you are taking, your past health history, and if you have any existing
allergies. Please be sure to tell your healthcare providers about all of your allergies. This information will help your doctor and other healthcare professionals choose the medicines that are best for you.
