Azathioprine ans Auto Inmune Hepatitis

I was diagnosed with AIH in March 2018 and the doctor is still trying to re balance my liver enzymes and function. The drugs used are  Prednisolone and more recently Azathioprine .I am 74 years old and I don't have a spleen due to abnormal red blood cells. (Old story , was operated at 9 years old ). He started me off with 100 mg of Azathioprine plus 20 mg steroid. Now I have to take 150 mg of Azathioprine plus  the other one .I don,t have a lot of help from the Hospital clinic or my own surgery and I need to know if I must take all the tablets together in one go or I can split the two groups, like 4 Prednisolone  in the morning and 3 Azathioprine with my evening meal. Because I also have to take blood pressure tablets in the morning ! Big cocktail .
