Hi everyone....so as I was flying on a 15 hour flight, I caught a nasty sinus infection that won't be resolved anytime soon based on how I'm feeling right now. I went to the doctor and he prescribed 5 tablets of 500 mg levofloxacin. I'm worried about tendon damage, but the doctor said he prescribed it to many people without any issues (in fact he said it's the most effective abx that's usually prescribed for most infections). It's worth noting that where I come from they prescribe this class of drugs without a black warning box. Any thoughts?

It's always a crap shoot for risk of being flox'ed. Double up on your Magnesium and just monitor for any strange neuropathy or tendon stiffness. If anything happens just stop immediately. Five days should have little risk.

I had tendon stiffness after 19 days on Levaquin, but six months later took cipro for long term with no issues.

I've always read horror stories on the internet about this drug, so I'm really scared of trying it. My dad took it for a bladder infection and told me that he couldn't get proper sleep for months as it felt like his mind was alert 24/7. He also got joint and tendon stiffness, but that resolved rather quickly. I'll just see how I feel after I finish the 5 tablets

just and FYI that it's not just the tendon rupture risk:

".....potentially permanent serious side effects that can occur together. These side effects can involve the tendons, muscles, joints, nerves, and central nervous system."


You need to weigh the benefits vs the risks.
