"Day 8. I have had the most severe sinus/double infection of my life, and this medication has helped tremendously! I was worried it wasn't working at first, but by day 5, I felt so much better! On the downside, I have terrible headaches almost all day. I'll skip a day, then the headache is back. Ibuprofen helps a little bit, not much. Dizziness is terrible also. I have a little confusion and frustration at times. It's not too bad. Just the awful headaches, but I remember how bad my infections were before this medicine, and it's worth it. Slight diarrhea, but no big deal."

"Within 6 hours of the first dose, intense itching of nostrils, face, scalp, chest, bottoms of feet, palms; pins and needles on back, inner thighs. Stopped taking it as an allergic reaction. Was to start Prednisone tomorrow, but at 2:45 am got up to take the first steroid dose, hoping to thwart these horrendous side effects. I pray the intestinal effects don’t hit me like they have others. I’ll NEVER use this drug again."

"My doctor gave me this for my sinus infection. The two days OK, 3 days got a blister on my lip, thought it was a cold sore coming on! I finished my medicine on Sunday, and I have experienced constipation and then diarrhea. Haven't stopped, and very bad cramps. Didn't know that this medicine causes side effects. I would never, never, never have taken it."

"I suffer from multiple sinus infections every year. Three days ago, I was prescribed cefdinir for the first time. It has caused unbearable nausea and diarrhea. After hearing that it has done the same for so many others, it angers me that a doctor would even consider prescribing this drug when there are other options that work better and do not have unacceptable side effects. Cefdinir is a failure in the field of medicine."

"My 7th day (out of 10) on cefdinir, and it did not work for me. It only gave me diarrhea and made me very tired all 7 days I was on it. I slept most of the time for the past 7 days. I was given it to treat sinusitis, which symptoms are the same, and now I feel I have bronchitis. My lungs and chest are filled with mucus. Still coughing non-stop like crazy, runny nose, post-nasal drip, headaches, fatigue, chest pain, congested. Cefdinir sucks! What a waste of my time & days. The doctor is going to prescribe another antibiotic. This time, a 5-day course. Insurance covered the medication, which I paid a $5.00 copay."

"Horrible. Given for sinus infection. Day 8 today, not feeling better. Got the rash right away but tolerated it because I was so miserable from sinus infection. I wanted to get better. Day 5, flu-like symptoms, thought maybe I had caught the flu from my son? Now, I don't think that was it, I think it was the meds. High fever, aches, and pains. Have had horrible headaches throughout, assumed it was because of sinusitis, now wondering if it was from the meds. Called the doctor on day 6, and she said to keep taking it and call back if not better in another day. Now have developed cough and diarrhea. After reading these reviews, wish I had read them sooner... pretty sure all my new symptoms are not related to the sinus infection but to this medicine."

"Taking this antibiotic was fine for around 6 days, and then I was struck with intense nausea. Eventually, it ended in me throwing up and unable to eat for a day. My muscles hurt, and I had bad diarrhea. Also, my sinusitis was not helped at all."

Cefdinir "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."

Cefdinir "I was just fine on Cefdinir for the first six days (actually, I remarked how this was one antibiotic that didn't wipe me out). I did take probiotics with it, along with the prednisone tablets (bronchitis and sinus infection). Then on the seventh day, when I took the last two, the cramping started. OMG. I am so sick! It has been two days since I finished the dosage, and I have a constant stomach ache and have trouble breathing. Gax X doesn't help the cramps much. I wish I had read these reviews before I took this stuff. So, this is going to last and last, and then, if it goes away, it comes back another day? That looks to be what I'm reading."

"I've been taking Cefdinir for 5 days so far with no adverse reactions as mentioned in some of the comments. No diarrhea, stomach cramps, etc. However, my sinus headache and cough are worse today... no better. I called my Dr. thinking he might want to give me a different type of antibiotic, but he said to stay on the Cefdinir. It's not helping. I am miserable. :*("

"Terrible, terrible antibiotic. I took a Z-pack for my sinus infection, which usually helps but didn't this time, so my doc put me on cefdinir. No problems until the 3rd day. I woke up with the most terrible diarrhea I've ever had. Same the following day. It's almost 3 weeks later, and I still have the diarrhea and have gone to the ER once for IV fluids to help with my dehydration. I would NOT recommend."

"I took Z-Pack for a full pack and still had an upper respiratory infection, so my Dr. prescribed this. I took it for 2 days and then started severe diarrhea, and after taking it for 5 days, I had to call 911 to get to the hospital. I was so dehydrated with diarrhea and nausea so bad I had to be hospitalized for six days! I see I'm not the only one that had these side effects."

"My doctor prescribed cefdinir for sinusitis. After finishing the first round, I was still having problems and called the doctor. He called in another round of the same prescription, which I finished a week ago. Still having the same problem and called today. He called in Omnicef again, and I am not sure if I will even pick it up. I take the full prescription as prescribed."

"Diarrhea after day 2, I stopped after the 7th day when I started vomiting. By then, the sinus infection was twice as bad. This med added bronchial infection, sneezing, itchy eyes, and nose. I feel like the doctor prescribed it to watch me like a guinea pig. The doctor’s office just said, well, those are the side effects."

"Was prescribed cefdinir 300 mg 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 the 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't stop, will have to stop at day 7 and see if I need another antibiotic or done. It's a very rough drug, and reading all the long-term possible effects is a bit scary."

"It was prescribed for a possible sinus infection. Knowing what I know now, I don't know why such a strong med was prescribed. I have taken things like amoxicillin in the past with no bad side effects. In addition to seeing no change in my symptoms, by the night of day 6 of 10 that I was supposed to take the drug, I was miserable. Shaking chills, dizziness, watery diarrhea, nausea with some vomiting. I actually wished that I could have vomited more because I felt so terribly nauseated. Now, on the morning after, still feeling nausea and dealing with diarrhea. Also headache. I hope and pray that the drug and its effects totally leave my body soon. I will never take cefdinir again. By the way, I did take the drug as prescribed and took probiotics."

"No side effects at all until my 4th day. I got horrible pain in my leg when going for an easy walk. I thought maybe I twisted my leg somehow? When I woke up, the pain had gotten a little better from resting it, so I took another pill like normal and 4 hours later went for a walk and my other leg started cramping, and I couldn't walk anymore at all! Had to have my bf pick me up. An hour after that, I had horrible widespread body aches, felt like I had the flu. A red rash that lasted a few hours on my face. I'm a 33-year-old healthy female, so I don't have arthritis or anything. I'm not sure if this was causing tendon problems or what. I still have sinus issues, but I guess that's better than not being able to walk and feeling like I've been hit by a truck."

"This is day 3 of taking the medication, and although my sinusitis symptoms have majorly improved, I now have severe diarrhea and a pounding headache every day. Between the two, I can barely function. If it doesn't improve by tomorrow, I'm going to call the doctor's and hopefully switch to something else."

"First sinus infection at 59 years old. My doctor is on vacation, so a nurse practitioner prescribed cefdinir. Took it for 5 days, stopped because of side effects: cramping, diarrhea. Was given a script of amoxicillin, which knocked out the sinus problem. The cefdinir effects went away a few days after I quit them, but as the warning says, it came back 8 weeks later with a vengeance. Has been 3 months now, my PCP referred me to Gastro, but when I told them I had gone to the ER and had blood work and tests for C-Diff 4 days before she called, I was told they could do a colonoscopy, but if I had an inflamed colon, there was nothing they could do but make it worse. If not inflamed, they could prescribe a couple of meds. Negative for C-Diff, taken 3 bottles of probiotics, lost?"

"I have been taking cefdinir for three days now. The second day taking it, I felt like I was getting better, but the third I felt sick again. I was diagnosed with sinusitis and an ear infection. I did not have drainage in the back of my throat until I started taking this antibiotic. I'm hoping to feel better soon, and hopefully cefdinir works."

"This medication was prescribed for my 8-year-old son and myself, both having sinusitis. To make a long story short, this particular antibiotic worked/works well for my son w/o any side effects. I wish I could say the same for myself. On about the 3rd to 4th day, I started having diarrhea, slowly to very moderately, meaning I hit the bathroom 3 to 4 times every hour, sometimes more. I should also add that I didn't notice any difference in my sinusitis, so the medicine just gave me really bad diarrhea, so not worth it to me. This antibiotic is a great medication for kids, from my standpoint, not so much for adults, unless you don't mind living in the bathroom."

"This medicine did help clear my sinus infection, but not nearly as fast as something like a Z-PAC or amoxicillin would have. And while it wasn’t as harsh on my stomach when it came to stomach aches and pains, it absolutely tore me up when it came to using the restroom. It has been 4 days since I’ve finished 12 days of this, and it’s still going. Overall, I wouldn’t take this medicine again, but it was effective at treating sinusitis."

"I was given this antibiotic for the first time just around the day before New Year's Eve 2017, and man, I will never take this again. Like most of the posts I read say, it was fine for about 5 days. Then on the 6th day, I noticed stomach cramping and severe diarrhea. I stopped on day 7 when I started realizing it was the antibiotic. In doing the research, I found that this is one of those broad-spectrum bacteria killers, so it also kills the good bacteria, and I think doctors should be more restrictive on prescribing this. Hopefully, I will be back to normal in a few days, if not, I guess back to the ER I go."

"I saw my doctor for a bad sinus infection. He prescribed cefdinir. I took the first one and within a short while was violently vomiting, sweating profusely, very weak. Called 911 to help get me off the floor into a chair to be wheeled to the car. Went to the emergency room. The ER doctor said nausea and vomiting were due to the serious upper respiratory infection, but I see here it may have been the cefdinir. If any of the future doses make me sick, I'm going to ask for a different antibiotic."

"My 5-year-old daughter was given this medication for sinusitis. 30 minutes after her first dose, she started trembling. We didn't know what was going on. Then suddenly, she started vomiting. We decided it was a reaction to cefdinir. Very scary. Threw the rest of it away."
