Does Humira cause fatigue?
Humira is used to suppress the immune system in patients with rheumatoid arthritis. This leaves the patient more susceptable to infections. The National Institute of Health lists fatigue as a symptom of infection and also of arthritis. Humira affects the nervous system, which can bring on a feeling of weakness. Fatigue is listed on WebMD as an unlikely but serious side affect of Humira, which should be reported to your doctor immediately.
