I ve taken clindamycin before but when I took it today before my dental appt, I ended up at the ER 45 minutes later. My blood pressure was 190/110 and heart rate was elevated. I had diarrhea, I felt nauseous and dizzy, weak and couldn t focus my eyes. The ER Doctor said if it was from a different manufacturer, they could ve used one diff component and my body didn t like it. All my labs, urine and chest X-ray were great. Any thoughts?
