Is it possible to get strep throat three days after finishing a 10 day treatment of Levaquin (levofloxacin) Infusions?

Strep/Levaquin. LLake ~ anything is possible but I think it would be very unusual in this case. The most likely cause if your sore throat following high dose antibiotics, is a fungal overgrowth in the pharynx, because the antibiotic has probably been very effective in killing the commensal bugs in the throat allowing the fungi to dominate. A 10-day course of any anti-fungal will do. Must be oral and not topical t.
Strep throat. it is possible.
