Which antibiotics are safest for people with myasthenia gravis?

When you have MG, choosing the right antibiotic matters because some can worsen muscle weakness or trigger a flare. The good news is that several antibiotics are generally considered safer options.

Safer antibiotic choices typically include:

* Penicillins (amoxicillin, penicillin V, ampicillin) - widely used for lung, skin, urinary tract, dental infections, strep throat, and ear infections
* Cephalosporins (cephalexin, cefuroxime, ceftriaxone) - effective for pneumonia, sinus infections, bronchitis, skin infections, and UTIs
* Vancomycin - reserved for severe infections like MRSA and blood infections
* Trimethoprim-sulfamethoxazole (Bactrim, Septra) - commonly used for UTIs, lung infections, and MRSA-related skin infections
* Nitrofurantoin (Macrobid, Macrodantin) - particularly good for UTIs since it concentrates in the urinary tract

Antibiotics to avoid when possible:

* Fluoroquinolones (ciprofloxacin, levofloxacin)
* Aminoglycosides (gentamicin, tobramycin)
* Macrolides (azithromycin, clarithromycin)
* Some tetracyclines (doxycycline, minocycline)

These can increase muscle weakness and worsen MG symptoms.

Important reminder: Always check with your neurologist or MG specialist before taking any antibiotic. Sometimes treating a serious infection outweighs the risk, and your doctor can help you weigh the options and monitor you closely if needed.
