Thanks for posting this question on HCM!
I really appreciate your concern for your mom's health.
The fall in
WBC count in the patients who are taking
Hydrea is due to the side effect of Hydrea involving
bone marrow which produces the blood cells.
Besides WBC, the platelets also decrease in number.
If WBC count level falls, your mother should avoid contact with people who have colds or infections.
Tell your doctor if you notice signs of infection like fever,
sore throat, rash, or chills.
Hydrea may reduce the number of clot-forming cells (platelets) in your blood.
Your mother should avoid activities that may cause bruising or
injury. Tell your doctor if you have unusual bruising or bleeding.
Consult your doctor for the possible use of Filgrastim which stimulates the production of WBC from bone marrow or to use alternate medicine instead of Hydrea for the management of blood disorder.
Wishing your mother a speedy recovery .
Regards!
