upper respiratory tract infection
"Was prescribed Augmentin for sinus and upper respiratory infection and within 48 Hrs I felt remarkably better. Before taking any meds I felt as bad as I have ever felt with any type of cold related illness.  I will now request this Med next time I have any similar illness. I did not experience any side effects except maybe a little thirsty. If so it was minor enough that I wasn't 100% sure that it was even a side effect."
