Thanks so much for all the encouraging replies!
I looked up my dad's medications using Birgitta_A's link
http://www.pdsa.org/about-itp/warnings.html and other web searches.
Two don't look good for delicate platelets, and I'm wondering how many MDS/AML patients are on cholesterol medicine?
His is Simvistatin, 40mg and I don't think he even needs it since he barely eats any cholesterol, and he weighs a lot less now. He has a good heart, maybe he could take less or stop taking it altogether.
The other one, Finasteride, 5mg, for his prostrate didn't sound good here:

His hemo dr is very experienced with MDS/AML and I know he has received my dad's list of medications.
One good thing about this is that I have talked to my dad on the phone more in the last month than the entire last year! We laugh about it,

and he knows I love him dearly .......
