bronchitis
"I was prescribed 300mg Omnicef. 
1 capsule 2x a day.
Very bad experience. I have had extreme diarrhea since the third day of taking this med. it is now 2 weeks after I finished the dose and am still experiencing problems. 
This med kills every "good" bacteria in your gut. I've been taking several different kinds of probiotics trying to get myself back to normal. This has been and still is an awful experience. Do not take this unless you like running to the bathroom every 30 minutes for weeks on end. I have not been able to eat much of anything and am still loosing too much weight. It is a very dangerous drug. I will NEVER take this again. "
