For Sinusitis: “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.”

“This drug cefdinir makes me feel like I am dying. I was prescribed Omnicef for a severe UTI which traveled to my kidneys. Day two I am vomiting profusely, I cannot stop having diarrhea and I genuinely feel like I am hallucinating and I am dying. I want to stop taking this med but I cannot deal with the pain of UTIs. I’m lost. Please say no to this med... stay away at all costs.”

For Sinusitis: “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.”

For Strep Throat: “Omnicef worked but it took until the 5th day on it to finally feel a tiny bit better. I had some side effects and my throat hurt so bad I couldn't sleep for three nights. I saw no visual difference until the 9th day. It almost looked as if on my third day it had gotten worse.”

For Sinusitis: “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.”

For Sinusitis: “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.”

For Sinusitis: “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.”

For Sinusitis: “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.”

For Bronchitis: “Within 36 hrs symptoms started to subside. Had no side effects with stomach (take with food). I suffer from bronchitis about twice a year. This medication was much more effective than Z-packs, Amoxicillin, or Cipro. I started getting mild headaches around day 4, Felt better but didn't clear up cough and wheezing. ”

For Otitis Media: “My daughter, who was 14 months at the time, had a severe reaction to this medication after being prescribed for 3rd ear infection in a year. She actually got worse and had severe side effects (aside from the gastrointestinal as mentioned by others) including vomiting, continued high fever and by the end of the second day - hives. I list it as a drug allergy now on all her medical paperwork.”

For Otitis Media: “My son had an ear infection and the doctor always gives amoxicillin first and it never works he always has to get Omnicef and then he starts getting better, he does have light diarrhea occasionally but nothing too horrible. I've had an ear infection myself and I was sick for 2 weeks before I went to the doctor. Thought I had a bad cold but when it just wouldn't go away found I had fluid build up in my ear. They prescribed Omnicef and it worked. I didn't have any diarrhea even though I already have severe IBS! I'd definitely recommend it.”

For Otitis Media: “This is the only antibiotic I will request for both of my children when they have ear infections. It is a one dose a day medicine that begins working very quickly and clears the infection. Diarrhea is a side effect, but can be controlled with diet and limiting dairy.”

For Bronchitis: “Worst experience ever. I took one capsule and two hours started diarrhea. I only took one more tablet 12 hours later. I had diarrhea for 4 weeks. I had hemorrhoid flair up. Never again will I take this drug. I think it took about 4 months to get my gut straightened out. Be very cautious of this drug”

For Otitis Media: “My son has taken this before and it worked fine. My 17 month old daughter was just prescribed this after amoxicillin didn't take care of her ear infection. After 4 days, her gums swelled up really bad, became bright red and then started bleeding on the 5 day. She also developed diarrhea. I immediately took her back and they put her on Zithromax. I think we are finally on something that will work for her. My son can take this medication, but my daughter can't.”

For Sinusitis: “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.”

For 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. ”

For Tonsillitis/Pharyngitis: “I get tonsilitis every year and recently I decided to go to the doctor to get some antibiotics. He prescribed me cefdinir and It worked great my tonsils cleared up but there is only problem. The side effects. I decided to not go the full 10 days and stopped using it after a week. I developed horrible vaginal itching as well as diarrhea which lead to blood in my stool. This medication did the job but I don't think I would ever take it again. Hopefully since I stopped this medication these side effects will go away soon.”

She's getting tubes put in next week so hopefully that ends this horror!!”
