... IV Clindamycin. It started when I topped responding to the antibiotics I was originally on for strep.. I developed an abscess in my throat and wound up with sepsis. That's when they put me on Clindamycin. My blood pressure is lower than its ever been and I don't see the disease and Infection specialist for another 15 days! I'm terrified that the long term use of this medication is going to cause more damage than the initial infection. I'm on 300mg every 6 hours. Has anyone heard of this medication being used this long??
