“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.”

“I started taking this for a sinus infection. The first 5 days I was fine and just added extra yogurt in 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.”

Frequently asked questions

“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 have taken 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.”

“300mg 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 have been on this for 5 days, sort of working, still have the headache though. I haven't really had any side affects yet. But I was given a 21 day dosage for (2) 300mg 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.”
