Sinusitis
"was prescribed cefdinir 300mg twice daily for 10 days for a sinus infection. I was having sinus headaches and mild fever prior, so at first I did not realize that the headache was from cefdinir now, and not from sinus issues. After first 5 days, severe diarrhea developed, and headaches and nausea continued. But it did seemingly clear whatever was happening in the sinuses. I am on day 6. if headaches and stomach issues don&#039;t stop, will have to stop at day 7 and see if need another antibiotic or done. It&#039;s a very rough drug, and reading all the long term possible effects is a bit scary."
