The most common way to treat angioedema is with antihistamines, according to Mayo Clinic. Depending on a person's individual situation, other medicines such as corticosteroids, autoimmune drugs and blood protein controllers may be used. Additionally, a person could use one of several home remedies, including applying a cool, wet compress and taking a comfortably cool bath.
Angioedema is a condition similar to hives but is characterized by swelling deep under a person's skin, states WebMD. This swelling results from the body releasing a chemical known as histamine. There are several things that trigger the immune system to release histamine, including allergic reactions, exposure to chemicals, certain medicines and exposure to sunlight. Antihistamine medicine reduces the amount of histamine in the body, treating the itching, swelling and other allergy symptoms, states Mayo Clinic.
If a person experiences a mild case of angioedema, then treatment may not be necessary, according to Mayo Clinic. However, if the swelling becomes severe, a person should visit her doctor. The doctor may order corticosteroids, which is a medicine that reduces inflammation, redness and itching. If corticosteroids and antihistamines are still not enough, a doctor may prescribe autoimmune drugs to stop a person's immune system from producing too much histamine. In cases of hereditary angioedema, blood protein controllers are effective at regulating certain blood proteins believed to cause the condition.
