I was told at the doctor's office that I had bronchitis and I was given Biaxin 500mg x 2 a day (generic form is Clarithromycin), I took it the first day wasn't sure if the side effect was from the bronchitis or from the medication. By the 2nd day, I took the first pill, after that it was downhill from there. I suffered anxiety, metallic taste in mouth, severe nausea, dizziness and vertigo. I feel completely horrible. I stopped taking the medication yesterday and I still have vertigo and nausea feels awful. The side of effects are worse than the sickness itself! Never again will i take this horrible pill!
