Prevention
Prompt treatment of giant cell arteritis is critical in order to prevent permanent tissue damage and loss of vision. Corticosteroid medications usually relieve symptoms of giant cell arteritis and may prevent loss of vision. [blood-test.biz]
Low-dose aspirin (81 to 100 mg orally once a day) may help prevent ischemic events and should be prescribed for all patients unless contraindicated. 1. [merckmanuals.com]
Treatment and Prevention Giant cell arteritis (GCA) is treatable, and complications can be avoided when treatment is started early enough. [rexall.ca]
