Hi JB,
I've come across the use of Levaquin for Lyme Disease, but haven't tried it myself. It's a pretty powerful antibiotic and has been associated with severe side-effects in some cases (tendon rupture and c difficile, for example). It's usually reserved for short term use of resistant infections.
Aside from Keypounds having tried it, I haven't come across anyone else on this board mentioning it recently. If memory serves, Keypounds' doctor heard about its use in Lyme Disease at a conference and was willing to try it….and. as far as I remember, I think she had two brief rounds with it. Haven't seen Key on the BB for ages, so perhaps she's recovered and doing well?
Peace, Maz
