Vancomycin
"This medicine given IV at 5X the recommended adult dose, along with the skill of the best surgeon in Cleveland, SAVED MY LIFE FROM MRSA - which at 9 am looked like a spider bite on my leg and by 1 pm had developed into an orange-sized deadly cyst. I was in isolation for 6 days, coma for one, and AM GRATEFUL FOR MY LIFE! Thank you to the scientists who developed this miracle!! [And don't ignore rapidly enlarging cyst-like growths!]"
