Training during and after levofloxacin risky for tendons?

Hi guys. I’m taking levofloxacin 750mg once daily for 10 days. Info online says a side effect of this antibiotic is tendon rupture or tendonitis even up to 6 months after taking it, so athletes are told to “be careful” if they have to take it (it is said the achilles tendon seems to be the most affected but the mechanism of action isn’t understood). What do you guys think? Should a strength trainee be careful while and after taking 750mg of levofloxacin (10 day course) and what would “being careful” entail? Less weight? Fewer sets? Thanks

Unfortunately “be careful” isn’t the most useful / actionable advice. There is an increased risk of tendon-related complications from this class of antibiotic. There is also no clear guidelines for how, specifically, activity should be modified as a result of this antibiotic. I suppose if I were in that situation I might limit top-end intensity, but this is just made up and not based on specific evidence.
