WARNING! Have to report that the Clarithromycin antibiotic has damaged my Achilles tendons!! So angry as my doctors know that I had the same problem when using the Fluoroquinolones.
Tendonitis is not shown on Clarithromycin as a possible side effect, but if you google it there's loads of research on it ... particularly with the over 60's and combining with prednisolone.
Not as bad (yet) as before but scared it's going to result in me being off my feet .. yet again.
