"Fantastic at clearing the sinus infection. I'm on day 4 and it's almost completely gone. The first two days were miraculous. But then, starting day 3... My stomach and intestines are rumbling almost constantly and I'm 'pooping' brown water 5+ times a day. I'm also utterly exhausted and weak, making it virtually impossible to actually do anything. If this gets much worse, I'm going to have to stop using this before the 10-day course runs out."

"I started taking this for a sinus infection. The first 5 days I was fine and just added extra yogurt to my diet to be safe. By day 6, I had a little bit of diarrhea, which was expected. It turned into diarrhea every 45 minutes until I had nothing left for the next 24 hours. Then it was like my bowels were being turned inside out, and all that came out was black mucus. I immediately stopped the medication. I’ve been about 36 hours without it, and things are slowly looking up. But I have had to miss work and other events because of it. My doctor said this was safe for those that are allergic to amoxicillin, but apparently not. I do not recommend this to anyone. If you read most other reviews, it’s about the same thing."

"I have taken it many, many times for my chronic sinus infections, and it seems to be the only thing that ever gets rid of the infection. I do get stomach aches from it and nausea, but it does what it's supposed to."

"300 mg 2 x day for 7 days prescribed for sinusitis. I think I may have felt like I was getting slightly better the 2nd and 3rd day, but after that it went back to the same as before. No adverse side effects, just didn't seem to work."

"Omnicef was effective in treating my daughter's sinusitis. However, she broke out in hives a day after finishing the medication. Although it is not certain the medicine caused her hives, it is very ironic that they broke out within 24 hours of finishing the antibiotic."

"I took this medicine for ten days. I took 300 mg twice a day. It was horrible, the side effects that I experienced. I had the worst yeast infection and broke out in the worst rash I have ever seen. It would bleed and itched so bad it about drove me crazy. I finally went back to the doctor. It took three months to get it all healed up. They should take this medicine off the market."

"I have been on this for 5 days, sort of working, still have the headache though. I haven't really had any side effects yet. But I was given a 21-day dosage for (2) 300 mg capsules. I have had 4 sinus infections since January. Hope it helps get rid of the headache. It has helped with the drainage and coughing though."

"This medicine made me feel worse than the original symptoms. I usually have a high tolerance for meds, don’t usually get dizzy or feel nauseous ever. But this medicine made me feel as if I was suffering from being hungover. I would drive 8 hours later after taking the meds and would feel like I could black out whenever. I would randomly feel nauseous. The headaches were a constant theme. Now that I’ve read the comments, I can attribute some of the diarrhea I had to it. I went back to the doctor and was prescribed Doxycycline, so I’m on day 4 and I feel better but still suffer from a cough."

"Today is day 6 of this medicine, and it just isn't working. I would have thought that I would have some kind of relief by now, but not."

"This medicine works very well. I didn't have a yeast infection, nor did I have the upset stomach, which I usually have with antibiotics."

"On the third day of taking omnicef I realized I was again constipated which is usually the norm for me but I've noticed more gas and extremely foul odor from my stools that I can't describe."
