I'm taking tobramycin since like 2 days because I have a little infection and I notice that I have a really bad breath after i'm taking it and I bruch my teeth the bad breath go away a little but after maybe an hour I still have a bad breath it's just not really fun I know it's not a big problem and all but I just wanted to know if it's normal plus I read on the internet that this product may cause a loss of hearing I hope it's not true.
