Hi Trey and Everyone, I am taking Imatinib 300 mg. daily. My blood work result from 04/21/16 showed the Lactate Dehydrogenase result to be elevated 834HH. The reference Range 313-618. I took Omeprazole 20 mg. daily for 32 days for my ulcer pain. Do you know if Omeprazole will increase the liver enzymes? I take Imatinib at 8:00 P.M. and Omeprazole at 9:00 A.M. My Hematologists nurse phoned me today to say that the LD is high, and that the Doctor wanted to know how am I feeling. I am feeling fine, in the evening I have drowsiness, but that's expected, I take the Imatinib in the evening. Also, Bcr-abl testing from March 23, 2016 showed a little increase from 0.11% to 0.13%. Your opinion will very much appreciated. Thank you.
