"I’ve taken this medicine before but I guess I was very sick. That I never noticed the side effects or maybe didn’t get them till now. I was on 300mg cefdinir 2x for 7 days. By day 6, I finally realized I was having adverse reactions and not just feeling sick. From a severe headache that nothing is helping, which includes pins and needles, with an extremely ITCHY SCALP all still present 24hrs after stopping! It’s driving me mad! It made my anxiety go through the roof, I felt pressure in my ears with tinnitus, intestinal distress, lack of appetite, thirst, feeling irregular heartbeats, feelings of overall malaise & doom. I seriously contemplated going to the ER thinking I was having a major health crisis until I looked at my date book & everything started on day 2 of antibiotics. I doubt it helped at all, as I tried hiding in bed most of the time. I hope this helps someone. Always journal when you're sick;)"

"Let me just say first, I was really scared after reading all these reviews, and was very reluctant to take it. But I really wanted to knock the sore throat and sinus problem I had had for 3 weeks at that point. I had taken amoxicillin and felt better for a week, but it came right back, so I was put on Cefdinir. I took it 2x a day for 10 days. I took it with a daily probiotic and Greek yogurt, and even Garlic Pills, and Pepto-Bismol when necessary. The only issue I had is one day I decided to eat buffalo wings about 3 days in during a football game... regretted that the next day. Other than that, I have zero complaints and my infections were finally knocked out. If you are reading the reviews and are reluctant, check with your doctor that you aren’t allergic to any medicines like this, and if you aren’t, go for it."

"I had severe sinusitis/throat infection, and within 24 hours of taking cefdinir, I felt 1000 times better, literally. I could finally drink water without being in pain because I could barely swallow beforehand. Yes, the side effects definitely suck, especially since I have the worst yeast infection due to the antibiotics, but I recommend cefdinir. Don’t let others' experiences with it scare you from taking it. Everyone’s different."

"I’m a healthy 22-year-old female with no health problems. The pharmacist gave me an antibiotic called Encef to treat a flu, it contains cefdinir. Thirty minutes after taking it, I started to feel anxious and discomfort. I started getting shortness of breath, and suddenly my heart just pumped one really strong pump and continued with extreme fast heartbeats. I fell to the ground and couldn’t get up anymore, I couldn’t breathe well, and it felt like I was having a heart attack. After being taken to a hospital, two hours passed, and the nurse told me that my heartbeat is back to normal and that I can take the antibiotic again, and that it wasn’t the cause of my incident. The next morning, I woke up fine, and when I took the second pill of the antibiotic, I experienced the same thing again after thirty minutes exactly-the sudden pump of my heart and fast heartbeats with shortness of breaths and severe anxiety. It felt like I was literally dying for about thirty minutes. I never took this medicine again."

"I took cefdinir for 7 days. My first symptoms were hives that started on the 6th day. Since I'm allergic to ampicillin, I decided to stop taking cefdinir because of the hives. Once I stopped taking it, I had two migraines. I've been having anxiety every day since I stopped cefdinir. Even today, a slight cough and also weird back and chest pain when I breathe. Has anyone else experienced any of these symptoms?"

"I was prescribed this medication to fight sinusitis back in August 2018, but all it did is kill pretty much my intestinal system. I have the worst diarrhea I have ever had in my entire 50-plus years. For the past 15 months, it has been living an awful life. I have had to take anti-diarrhea medication almost daily. Some days it is so bad I can't leave my house for fear of an accident. There are times I don't make it to the bathroom. I have been seeing a gastrointestinal specialist multiple times trying to get this resolved. They are still trying to figure out how to stop the episodes. I have taken antibiotics in the past with no side effects, but this is the worst. The negative side effects from cefdinir will make a big impact on your quality of life. It has affected my personal and professional life as well as my finances. I can only hope that more people read the warnings of any drugs so you can avoid potential issues that pharmacists or doctors don't tell you about."

"Every winter, I end up with sinusitis/infection that triggers intractable migraine. It’s beyond miserable! This is the first year I have been prescribed cefdinir. I was very nervous to try it after reading reviews, but I am happy to report, so far, I have no issues aside from a noisier stomach. To be fair, I am also taking prednisone. I feel SO much better on just day 3! I will update if I end up with bad side effects, but so far, so good."

Cefdinir "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."

"This was my 3rd trip to the doctor. First, I was given 875 mg amoxicillin, but 3 days later, I was worse. Went to an urgent care clinic and was given a shot of Rocephin, a steroid, and another antibiotic. Those 3 things cured the sinusitis and the bronchitis I had, but I was still sick. The doctor this time prescribed cefdinir, and it took 5 days, but on the 5th day, my pneumonia was gone - finally relief! Now, I get to see how long it lasts. 3 days not sick so far (I'm one of those unlucky people that are sick more than they are healthy), and the cause is 9 times out of ten, sinusitis. If it progresses without infection, well... let's put it this way. I have sinusitis 9 to 10 times a year, bronchitis 7 to 8 times a year, and full-blown pneumonia at least 3 to 4 times a year. I live with this as normal. Cefdinir really helped me this time."

"I was prescribed this cefdinir for a sinus infection. Supposed to take one 300 mg pill twice a day for 7 days. I took the first pill around 7 this morning, and by 11, I had horrible cramps, nausea, and diarrhea. It’s now 1:30, and I cannot leave the toilet. I will not be taking another pill if I survive this day. If you’re looking for a good colon cleanse, try these. Otherwise, AVOID AT ALL COSTS."

Cefdinir "I started taking this for a sinus infection. The first 5 days I was fine and just added extra yogurt to 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."

"Second time I’m on this cefdinir at a dose of 300 mg for ten days, twice daily. Worst medicine with horrendous side effects: light-headed, acid reflux, inability to sleep, nausea, with severe reactions. Almost lost consciousness several times, inability to control urine, and of course severe diarrhea. Horrible stuff."

Cefdinir "I have taken it 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."

"I took this medication, cefdinir 300 mg, dose 2x a day for a sinus infection for 10 days. I have a VERY VERY sensitive stomach-I didn't have ANY stomach upset (maybe just some gas). Don't let the reviews scare you if you haven't started them yet. I tend to be the 1 in 100 people that have reactions, and I was fine. By day 10, I did end up with a yeast infection-woohoo for being female. After day 2/3, my face felt better. Make sure you take them with a meal, and you'll be fine. Tip: take a probiotic 2 hours after your antibiotic. Although it didn't touch my ear infection, I'm now on a round of amoxicillin."

"After 4-5 days of taking this antibiotic cefdinir, I began to turn yellow because my liver had begun to shut down. Fortunately, my doctor ran a test which showed bilirubin to be off the charts. I was instructed to get to the emergency room, ASAP. Ended up in the hospital for four days. Apparently, I am 'one in 100,000,' but I would like for the manufacturer to pay my hospital bill. Once I stopped taking cefdinir, my liver recovered rapidly."

"I was prescribed Cefdinir after getting a sinus infection and bronchitis. It solved that problem in just a few days, but after 3 days on it, my diarrhea became intolerable, far worse than the original sickness. I stopped taking Cefdinir. It's been over 3 weeks now of non-stop gastrointestinal pain that landed me a colonoscopy procedure, stool cultures at the hospital, and persistent diarrhea. The worst of which culminated in a near blackout from pain on the toilet. My case may have been a rare exception, but I'm certain Cefdinir is no friend of mine."

"I am on Day 6 of this antibiotic. I am not a huge fan of antibiotics, but my vertigo and head pressure from the sinus infection were enough to get me on them. For the first 2 days, I had no vertigo and head pressure, but now I experience some of it on and off throughout the day. So, I use a Neti Pot to clear out my sinuses. Two days ago, I had post-nasal drip, where I ended up throwing up mucus in the middle of the night. With my experience, I have noticed a loss of appetite and have lost about 5-6 pounds. If I do not take the capsule with food, I will end up with heartburn. I am looking forward to being over with this (4 more days to go). I take a probiotic in between the doses for my digestion."

"I am on day 7 of this antibiotic for a sinus infection. While my symptoms have all but gone, I still have to keep taking it, of course. I noticed a couple of days ago that I was feeling 'funny' approximately 2 hours after taking the medicine. It wasn't like that at first, but now I have body aches, headache, chills... kind of reminds me of the flu."

"I took cefdinir antibiotic for a sinus infection for three days. I ended up having to stop because I was having such bad diarrhea and cramping, which isn’t good since I’m pregnant also. Ended up having to go to the doctor three different times to figure out I now have a C-diff infection from this medicine and now have to take a different antibiotic to clear that up. If you’ve never heard of C-diff, it’s an infection of your intestines and makes you have to go to the bathroom ten or more times a day! Wish I never would’ve started this antibiotic in the first place!"

"Do not take this drug. I am not allergic to any antibiotics and haven't ever had a bad experience. Because of this drug, I am now fighting a very serious C. difficile infection. Most people haven't even heard of C. diff, but when you do, your life changes. C. difficile isn't as treatable as the internet suggests. This drug is absolutely the reason my life has changed. Do not take it. In fact, ANYTIME you take an antibiotic, take a probiotic (spaced away from the antibiotic dose) with it. And another thing I've learned, there are certain antibiotics you should ask for--NARROW spectrum, ALWAYS. Broad-spectrum antibiotics destroy your gut. If you have to take a broad-spectrum antibiotic, supplement with a probiotic. I cannot stress this enough!"

"Went to urgent care for an upper respiratory infection. Cefdinir, after 1 day, helped with the respiratory problem but left me suffering with intolerable diarrhea. I'm taking probiotics and just had to take a Lomotil. No pain, but just pure and simple constant running to the bathroom. I'm 70 years old and consider myself an athlete and very strong. Rarely sick, but this has taken me down, I stopped the cefdinir after 5 days. Could not take it anymore."

"Went 10 days ago to the doctor for a runny nose and a real bad cough, both being productive. Put me on cefdinir 300 mg. On the last day of taking the medication, and I am still no better, coughing to the point that my voice is raspy. I almost pass out, my chest burns and hurts from coughing so much, still have drainage, still have bloody discharge in my nose. On the good side, no side effects, it's just not working for me."

"The bad reviews sound awful. I have taken this antibiotic several times and have no adverse reaction. I am currently on 300 mg 2x daily and it kicks butt on the infection. I recommend it for those who can take it."

"Started this to fight a sinus infection. Four days in, seemed to improve. Only negative was a bad headache. Night four, horrible night sweats and chills to the bone. I couldn't function at work and was still getting chills and stomach cramps. Then the constant diarrhea started. Day five, I had a fever of 102 to go along with body shakes, headache, and still diarrhea. I thought it was the flu, so I continued medication, but by day seven, I had had no relief from it, called my doctor, and she told me to stop meds immediately. I just stopped and am hoping for some relief. I am dehydrated and weak and still can't leave the bathroom for more than 20 minutes! Bad reaction and hoping for some relief!"

"Been taking this for five days. The pressure in my sinus is lessening, and my fever is gone, but mucus production has increased, and so now my cough is worse. Does this mean it's not working? The best way I've found to avoid the adverse digestive effects (vomiting, etc.) is to take a strong probiotic to replenish what the antibiotic kills. You can ask your doctor for a prescription-strength probiotic (they prescribe them for patients with ulcerative colitis) or find them in pill or drink form at a health food store."
