Change of medicine. My old prescription.

Iam47year old diabetic neuropathy patient. My last clinical test was on10thaug this year. My test report is like that hba1c 5. 9.creatinine label 0.9.that time I take metformin hydrocloride500mg twice a long with novomix30. Twice before breakfast and dinner 18 and 12 unit. And lantus 20 before bed. After that my doctor suggested me to take novomix30 before breakfast18 and before dinner12and lantus18 before bed along with transpire m30after breakfast. My problem is that recent report shows my hba1c raised from 5.9 to 7.5 and cretinine label from0. 9to 1.and fasting sugar is 84(previous)to 144 now. Please suggest Me what to do.sir either I continue the medicine of Dr. Last prescription or I switch over to my old prescription. Thanks
