Hi, I had gone through your question and understand your concerns.
APIXABAN is an anti-coagulant mainly acts by inhibiting the clotting factor in the blood.
It is indicated to prevent
blood clots formation who have increased chances due to diabetes or
atherosclerosis and
deep vein thrombosis.
Muscle pain and numbness may not be due to the tablet.
