Atgam treats a condition called aplastic anemia by using antibodies from horses to target and destroy certain immune cells, helping your bone marrow make healthy blood cells again.
Your doctor will decide your dose based on your body weight. The total dose is 160 mg per kg of body weight for treatments that suppress the immune system. This might be given as 16 mg/kg daily for 10 days, 20 mg/kg daily for 8 days, or 40 mg/kg daily for 4 days.
Atgam is given as a slow drip (infusion) into a vein by a doctor or nurse.
The highest daily dose you can receive is 40 mg per kg of body weight.
