Albendazole may affect blood and lympth. It may also lead to reduced white blood cells [leukopenia] and low platelets where the latter causes [thrombocytopenia].
This happened to me 7 ago where I lost blood in my urine and my arm's smaller blood vessels bled when pressed.
I have taken ABZ again last September without any of these side effects.
suggest you seek advice from your doc to have a WBC [white blood cell count] carried out.
