Perichondritis - doc gave me Moxiclav

I suffer from perichondritis for about a year due to a minor accident that injured my ear. My ear is perfectly fine except that it gets red and hard. I was wondering if Moxiclav(amoxicillin and clavulanic acid) is a safe drug? I was given 2 weeks supply. Which pathway does it go to get detoxified? Are there better alternatives? I've been taking bromelain but it only reduces inflammation.
