I do have a PPI for Tasmar. Under the laboratory test section it states: It is recommended that transaminases be monitored monthly for the first 3 months of treatment with tasmar, after which LFTs should be monitored every 6 weeks for the next 3 months. If elevations occur, and a decision is made to continue to treat the patient, more frequent monitoring of complete liver function is recommended. Treatment should be discontinued if ALT exceeds 5 x ULN or if jaundice develops. Hope this helps, David McElveen
