[|Human|] Have low blood platelets 30 k Had bone marrow biopsy it showed nothing. Dr started me on a course of Predisone taking 6  20mg tablets a day for 2 weeks,then 4 a day for 1 week ,then 3 a day for 1 week then 2 a day for  a week then 1 a day for a week ,plus sptra/bactrim ds 2 pills a day on Mon.wed.and Friday. Taking this much kinda scars me, but i guess it is what i must do.
[|AI|]  Thanks for putting up your question so nicely. Decreased platelets counts (pancytopenia or thrombocytopenia) is due to many causes and if every test comes normal and no cause is associated, then it is called "idiopathic thrombocytopenia" which simply means "decreased platelets without any cause."  If I were attending my patient, and every blood test I did come normal except platelets. I would prescribe the same Chat Doctor.  Sptra/Bactrim is antibiotic which is prescribed by the doctor because steroids (prednisone) reduces immunity.  Yes you have to take these
