For Sinusitis "Was prescribed this for suspected strep throat. I had a fever, so the doctor went ahead and prescribed this to me. First day, I had loose stools and nausea. This continued until the fifth day, I had severe muscle pain and a severe headache. It was a struggle to just walk to the bathroom. Right now, I have watery diarrhea and stomach cramps. Earlier today, I had a fever and severe body chills. Over-the-counter pain meds have not made a dent. Last night, I was tossing and turning in pain and got very little sleep. Cure worse than the cause! I've tolerated many other antibiotics very well in the past, and I will never allow my doctor to prescribe this to me again."

For Skin or Soft Tissue Infection "On cefdinir for an upper respiratory tract infection. The first few days, my stomach was making these funny noises, but I was ok! On day 3, I had a vaginal yeast infection and a slightly sore throat that lasted for 3 days! On day 7, I started feeling dizzy and a little off, my anxiety was through the roof! On day 8, my shoulders started to ache! I have 2 more days, and I’m gonna try to finish them up. I did have one red stool throughout the time on this medicine!"

For Tonsillitis/Pharyngitis "I'll give it credit that it did make me feel better - but the cost was a very upset stomach. I've never had issues with antibiotics upsetting my stomach before, but this medicine gave me really bad diarrhea one day after starting it. Still not over the diarrhea after almost a week off the medicine. Obviously, everyone reacts differently, but I won't be using this medicine again."

For Sinusitis "For the most part, this medicine did help me clear my mucus and congestion, but it gave me tinnitus in my left ear (buzzing sound), and now when I yawn, that buzzing sound is amplified. Second, the thing which I believe it did was give me ear pain. Even though I was given this for a supposedly sinus infection, I didn’t think I had an infection in the first place. I didn’t have much stomach issue, as I was taking a probiotic while taking it, so that helped a lot."

"Be careful taking this. I experienced very bad stomach aches, gas, and bloating, along with very watery diarrhea for about 2 weeks after taking it. Only just now feeling better after week 3. Highly recommend taking a strong probiotic to help rebuild your gut."

Cefdinir "Great drug, one dose, and your UTI is pretty much gone, but so is all the other bacteria you need. This medication made me so violently ill. Vomiting, watery diarrhea, and stomach cramping. Had to pull over while driving to vomit (never had to do that before in my life, not even when I was pregnant). Thankfully, it has a short duration of activity in the body, so by the next day, I was okay. But this went straight into the garbage can after that."

For Sinusitis "I'm sensitive to meds and suffer from bad anxiety, but Omnicef is tolerable. Not bad. This is my second favorite antibiotic, followed by another one that doesn't treat sinuses, so if I have sinusitis, my options are quite limited. Side effects on days 1-4 are nonexistent, and then from days 5-10, small and manageable. Maybe a small, short-lived stomach ache on the rare occasion, but tolerable. I don't get an upset stomach. I'll also have minor insomnia, but nothing bad."

For Pneumonia "Started with a cold, but better in 3 days. A couple of days later, bad sneezing/coughing spells, body aches, and lack of energy!!! I still hung tough, thinking it had to eventually go away…until I got to the point that I was so sick I couldn’t get out of bed! A friend helped me go to the hospital and I was diagnosed with pneumonia and prescribed five days of cefdinir, 300 mg, twice daily. After the first day, I could feel a difference and was able to get a few things done. I felt even better on day two; HOWEVER, I was up all night with diarrhea! On day three and four, I was back to feeling really crummy. Today is day five and I feel absolutely horrible, with diarrhea, stomachache, headache, exhaustion, whole body aching, and difficulty remembering how to do simple things, like opening our car door!!! Hope it killed the illness, but it is day five and glad I no longer need to take this medication!!!"

For Sinusitis "I frequently get sinusitis bronchitis. I have a low immune system. I am liking this med and am feeling a little better almost 24 hours later. I don’t like the upset stomach and have to be near a bathroom, but it’s worth it to be able to breathe and get rid of this nagging cough and wheezing, etc."

Cefdinir for Sinusitis "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."

For Strep Throat "Was prescribed this cefdinir for strep throat. The side effects are terrible. Worse than strep itself. Extreme fatigue, weakness, fogginess, and stomach issues. Will not take this again."
