Fludara and Blast cell count increased - a phase IV clinical study of FDA data

Summary:

Blast cell count increased is reported as a side effect among people who take Fludara (fludarabine phosphate), especially for people who are male, 2-9 old, have been taking the drug for < 1 month also take Oxycodone, and have B-cell type acute leukaemia.

The phase IV clinical study analyzes which people have Blast cell count increased when taking Fludara. It is created by eHealthMe based on reports of 46,669 people who have side effects when taking Fludara from the FDA, and is updated regularly.
