For Pneumonia "I was diagnosed with a rare hereditary disease PI (Primary Immunodeficiency Disease). My type is called Hypogammaglobulinemia. The immunologist I see prefers this antibiotic as a backup because of its effectiveness and very low probability for side effects. I have been taking it since November of 2018. I also have to take an IGG drug that gives my body the ability to actually fight the many different bacteria that cause all types of pneumonia, most that are very deadly. This antibiotic works well."

For Bronchitis "Mystery bacteria. Perhaps bronchitis or laryngitis? Doctors never know much, do they? Let's try this. Well, it did seem to ease my sore throat and get rid of whatever was in my lungs. Not really many side effects."

Cefdinir for Sinusitis "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 for Sinusitis "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."

For Tonsillitis/Pharyngitis "Prescribed this drug because of a history of MONO with tonsillitis. I was very reluctant to take it but went ahead anyway. Besides the pill smelling like death, 4 days into it I was better and expedited extremely bad cramps, diarrhea, and bloating. I mistakenly took another dosage and was filled with hives all over. Still dealing with the second day of hives, the ER gave me 5 days of steroids. I’ve been on tons of antibiotics for recurring strep and tonsillitis and have NEVER experienced something like this."

For Sinusitis "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. :*("

For Sinusitis "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."

For Sinusitis "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."

For Sinusitis "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."

For Skin and Structure Infection "The cefdinir antibiotic caused severe side effects. Immediate headaches that lasted for 9 hours with no previous history of such. After 3 days: severe joint inflammation and pain to the point of not being able to walk up the stairs without pain."

For Sinusitis "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."

For Sinusitis "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."

For Sinusitis "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."

For Sinusitis "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."

For Bronchitis "I felt much better rather quickly. However, roughly 3 days into the medication, I experienced diarrhea, which subsided by day 5 and was followed by horrid itching of my anus. On day 9, the itching had spread to my lady areas. I am miserable and will never take this again."

For Sinusitis "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."

For Sinusitis "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."

For Sinusitis "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."

For Sinusitis "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?"

For Bronchitis "Was given it for a suspected respiratory infection after COVID. I started to have diarrhea the first day (6x that day) and continued to the next day. At this point, I had taken four pills (1 every 12 hours), and my doctor instructed me to stop taking it. It’s been a month, and I continue to still have GI issues (diarrhea, abdominal pain, fatigue, loss of appetite). I’m working with a GI to resolve these issues, but in all honesty, I was perfectly healthy (22 years old) prior to taking this antibiotic. I didn’t even feel this bad when I had COVID. I honestly would try to take another antibiotic and to make sure you actually need them. A lot of doctors just give antibiotics out like candy, and that was my case. I had no infection, and it was most likely lingering effects of COVID because all the symptoms had gone away on their own, and now I’m dealing with GI issues I’ve never had until taking this antibiotic."

Cefdinir for Bronchitis "I was prescribed 300 mg 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 losing too much weight. It is a very dangerous drug. I will NEVER take this again."

For Bronchitis "It cleared up the bronchitis in a short time frame. Side effects are fatigue, loose stools. Lots of yogurt and rest. The doctor combined it with a short blast of steroids. The other doctor helped with a breathing treatment and cough medicine with codeine for night. Was nice to be able to sleep. It was a good drug for me. I am a non-smoker, but the dust and stuff at work just made the cold a monster to get rid of."

For Sinusitis "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."

For Middle Ear Infections "My daughter was prescribed this cefdinir, and she has been dealing with all the bad common side effects. She is missing a day of school now because she is so sick. I can't understand why her doctor would prescribe this. She has always taken amoxicillin in the past with zero issues. They shouldn't be prescribing this stuff."

For Bronchitis "Going right down the middle on this one because there were some positives and negatives with this medicine. Positive: it cleared up my sickness (no diarrhea or stomach issues either). Negative: it has given me fevers, and it gave me a severe vaginal yeast infection and bacterial vaginosis that took almost 2 months (and 4 doctors' visits) to clear up."
