Cefuroxime
"Have suffered from allergies and 2 to 4 sinus infections yearly for most of my life.

Have tried many antibiotics,  but Ceftin works the best with the least side effects. I agree with other comments. After only 2 doses of a 10 day course I already felt 50% better. I am an RN and I have seen Zpak and Augmentin fail people during sinusitis treatment. This drug is my go-to now. It truly cures the infection. I only get maybe one acute sinusitis per year now, thanks to this drug."
