Great question, and an important one! Some antibiotics can worsen MG symptoms by interfering with nerve-to-muscle signals, so knowing which ones are generally safer is really helpful.

Since you're allergic to penicillin, here are some typically lower-risk options to discuss with your doctor:

- Cephalosporins (e.g., cephalexin, cefuroxime) — Note: since these are related to penicillins, let your doctor know about your allergy before taking them
- Clindamycin — useful for dental, skin, and bone infections, though it can cause stomach issues
- Trimethoprim-sulfamethoxazole (Bactrim/Septra) — often used for urinary and skin infections
- Nitrofurantoin (Macrobid) — mainly for bladder infections
- Vancomycin — typically reserved for more severe infections Antibiotics generally best avoided with MG include:

- Fluoroquinolones (e.g., ciprofloxacin, levofloxacin)
- Aminoglycosides (e.g., gentamicin)
- Macrolides (e.g., azithromycin)

Always tell any prescribing provider that you have MG. Your neurologist may also need to be involved if the antibiotic choice is complicated or your symptoms aren't stable.
