I realize I am tremendously idiotic, my guinea pig was supposed to be taking .08 mg of baytril twice daily for a URI. I misread and gave her a dose of .8 mg. I almost immediately after realized what I had done and began researching. I saw that this can be fatal. It has been over twelve hours and she has no symptoms of overdose but i’m not sure for how long I should be worried about it. I don’t know how long it will take for the medicine to pass through her system. I don’t know if/when I should continue the treatment for her URI. If anyone has any insight please help, I am so worried.
