Consider starting weekly methotrexate. a

Why?

  • Patients with giant cell arteritis who take steroids and weekly methotrexate compared with steroids alone are less likely to relapse. a
  • There is no clear difference in the rate of withdrawal due to adverse effects. d
  • Patients use less steroid (in one study 1100 mg less prednisone over 2 years). a


Weekly methotrexate combined with steroids reduces giant cell arteritis relapses
