Ceftriaxone
"I've had a persistent UTI and been through 2 rounds of oral antibiotics and it kept coming back despite having had a culture done to determine what would be effective. Once the pain got bad enough that the pyridium was no longer effective, I called the doctor and begged for help while still waiting for the second culture results. They gave me a shot of Rocephin. By morning I felt 85% better. The second day, I still feel a twinge of symptom here and there, but feel soooo much better. The shot hurts, yes. But it's not THAT bad, and there is was lidocaine in my injection to help with that. Powerful stuff - so glad they gave it to me!"
