Oh no — a cat bite on a vein sounds really unpleasant, and it's completely understandable to be worried, especially with MG in the picture. The exhaustion and possible eye drooping you're noticing could very well be connected to the antibiotic you're taking.

Yes, some antibiotics can worsen MG symptoms. The ones most likely to cause problems include:

- Fluoroquinolones (e.g., ciprofloxacin, levofloxacin) — can block muscle signals, leading to weakness, drooping eyelids, and breathing difficulty
- Macrolides (e.g., azithromycin) — can interfere with the nerve-muscle communication that's already compromised in MG
- Aminoglycosides (e.g., gentamicin) — can also worsen muscle weakness
- Some tetracyclines (e.g., doxycycline, minocycline) Safer antibiotic options for MG include penicillins like amoxicillin or ampicillin, which are commonly used for skin infections — relevant for a cat bite situation.

It's really important to contact your neurologist or MG specialist right away and let them know which antibiotic was prescribed. They can help switch to a safer option if needed and keep a close eye on your symptoms.

Watch carefully for any breathing difficulties or significant worsening — that would need urgent attention.
