I recently had a course of metronidazole for a gum infection. During that I had a battery of blood tests taken.my consultant has telephoned to say my liver enzymes have doubled and I must 're test. Has anyone else had this? Did things return to normal after completing the course?
I’ve taken Metronidazole for tooth infections and I also took it some years ago for a Clostridium Difficile infection. I had to take it for about four months for that. I’ve never had any difficulties with it and tolerated it very well. You can’t drink alcohol when taking it though.
I only took it for a few days for a tooth infection and had no problems. I suggest you look at the leaflet which gives information about possible side effects. The liver problem may have nothing to do with the drug but your doctor should advise.
