any anti-biotic used long term can cause liver damage.
doxycycline potential liver damage. i don't drink smoke or have any vice. i get annual exams and my liver always checks good. about a week before my annual exam this year i had just completed a two therapy of doxycycline and my liver values alt and ast were out of range. alt was 6 points out of range and ast was 9 points out of range. . is this possible stress from the antibiotic cycle? are these values high or demonstrating damage to be concerned about? . . thank you.
