Sinusitis
"Wow, this is a POWERFUL drug. I was prescribed clindamycin 300 mg for severe sinus infection. Amoxicillin did not work. After two doses I had the worst stomach pain and nausea I have ever had. I also had a throbbing headache. However I could feel it working in my sinuses already. So I tried to stick it out. After another day I was so profusely ill I couldn&#039;t get out of bed. Had the shakes, vomiting, horrific heartburn and headache. For the record I took the pills with Gravol and water, took probiotics and stayed upright after taking. This was not a good experience. Very frustrating because I believe the drug does work but the side effects make it impossible to take."
