Yes, certain antibiotics can worsen MG symptoms and should be avoided when possible. These antibiotics can interfere with the way nerves communicate with muscles, leading to increased muscle weakness.

The antibiotics generally considered risky for people with MG include:

- Fluoroquinolones (e.g., ciprofloxacin, levofloxacin) — can cause breathing problems, swallowing difficulties, drooping eyelids, and double vision
- Macrolides (e.g., azithromycin, clarithromycin) — can reduce the effectiveness of acetylcholine, which is already impaired in MG
- Aminoglycosides (e.g., gentamicin, tobramycin) — risk is higher for those who also have kidney issues
- Some tetracyclines (e.g., doxycycline, minocycline) There are safer antibiotic options that are generally better tolerated with MG, including:

- Penicillins (e.g., amoxicillin, ampicillin)
- Cephalosporins (e.g., cephalexin, ceftriaxone)
- Vancomycin (used for severe or resistant infections)
- Trimethoprim-sulfamethoxazole (Bactrim/Septra)
- Nitrofurantoin (especially for urinary tract infections)

It's important to always check with your MG specialist or neurologist before taking any antibiotic, as sometimes treating an infection is critical — and in some cases, the infection itself can trigger an MG flare.
