Amoxicillin / clavulanate
"The drug so far has been ineffective.  I was prescribed Amoxicillin 875mg 2x/day to treat my strep throat infection.  I'm an adult and my only symptom is a swollen, painful to touch lymph node on the left side of my neck.  Today is day 6 and I still don't see any difference compared to day 1."
