hey... i was prescibed esomeprazole & nortriptyline+fluphenazine. i was suffering from peptic ulcer. i have taken it for 2 months. now i want to treat my acne vulgaris. before starting medication doctor has suggested me to do some tests. CBC,ESR,SGPT,creatinine,serum iron- among these i have done ESR & SGPT 2 months back before starting esomeprazole. now,should a repeat these 2 tests? have the 2 drugs any effect on ESR & SGPT level?
