WHAT YOU NEED TO KNOW:
Hypereosinophilic syndrome (HES) is a group of conditions that causes you to have too many eosinophils. An eosinophil is a type of white blood cell. Allergies, asthma, parasitic infections, and certain medicines may increase the number of eosinophils. Organs such as your skin, lungs, heart, or brain may be damaged if you have too many eosinophils. They may also harm your kidneys, intestines, liver, or spleen.
- Medicines are used to decrease inflammation and swelling. You may also get medicine to decrease the number of eosinophils in your blood.
- Take your medicine as directed. Contact your healthcare provider if you think your medicine is not helping or if you have side effects. Tell him or her if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits.
