HI I HAD HIPATITIS AT LEAST 12 YEARS AGO AND I HAD IT REALLY REALLY BAD, GOT IT FROM MY KIDS WHO HAD YELLOW YAUNDICE, THEY WERE NOT EFFECTED SO BAD AND GOT OVER IT QUICKLY, I HOWEVER GOT SO SICK I THOUGHT I WAS DYING, COULDNT KEEP ANYTHING DOWN, ITCHY SKIN.  ABOUT A YEAR AGO I WAS PUT ONTO AVALON ANTIBIOTIC FOR BRONCHITIS AND IT EFFECTED MY LIVER AND I WAS IN SEVERE PAIN AGAIN. I STOPPED THE ANTIBIOTIC AND IT CLEARED UP AFTER ABOUT A 2 WEEKS.  A WEEK AGO MY GP PUT ME ONTO ANTIBIOTICS AGAIN,  CEPADEM AND AFTER THE 2ND DAY I HAD TO STOP AS IT WAS EFFECTING MY LIVER ONCE AGAIN, ITS BEEN A WEEK NOW AND IM STILL EXPERIENCING NAUSEA, TIREDNESS AND PAIN IN MY LIVER AREA, I CAN FEEL ITS STILL SWOLLEN. I HAVE HAD A DISCHARGE OF BLOOD BUT NOT FRESH BLOOD AND ITS CONTINUING.  SHOULD I BE CONCERNED OR IS IT JUST PART OF THE HEALING PROCESSES MY LIVER NEEDS TO GO THRU?
Hi and welcome to Chat Doctor. Thank you for the query. This is not common side effect of antibiotic, but is possible. This shouldn't cause some serious liver damage and 3-4 weeks may be necessary till LFT recover. You should just stop this or any similar Chat Doctor.  Avid hematologic substances and check your LFT frequently. Wish you good health. Regards
