"I've been taking for 6 days for acute bronchitis. I was taking with Tamiflu but finished that prescription. I have very uncomfortable heartburn and my throat feels a bit weird and itchy but i don't have cold symptoms. My blood pressure has also increased and my heart is racing. I've been searching to find if Cednifir increases blood pressure but haven't been able to find anything. I feel like if you have high blood pressure this may not be for you. Also the heartburn is very uncomfortable. Like on a scale of 1-10 my heartburn is at a 6."

"started taking this cefdinir medication after having a cold that turned into a sinus infection. Took both doses day 1 but then read the reviews and decided to stop; however, the sinus infection was so frustrating I decided to continue and started up the next day. Was fine for 1.5 days but that night I got terrible aching in my legs and bad dry mouth along with insomnia and anxiety. Although I saw an improvement in the infection within the time I was taking it, I’ve taken other antibiotics that work just as well without the side effects and will not be taking this again. I just hope it leaves my system and causes no other issues:/"

"I've had roughly 8 sinus infections over the past 20 years and this is the first time I've been prescribed Cefdinir. I've taken it as prescribed, one pill every 12 hours, for the past 24 hours. Unknown if this is working on my sinusitis, as my attention is now 110% focused on the most horrific and violent case of perpetual diarrhea I've ever experienced. Colonoscopy prep doesn't compare to this. The prescribing doctor and I will be having a conversation when the clinic opens later today."

Omnicef (cefdinir) "300 mg 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."

"I have never taken an antibiotic without experiencing at least some negative side effects due to being extremely sensitive to most medications. Omnicef/Cefdinar is the only antibiotic my body tolerates with zero negative side effects. Over the years I have taken it for respiratory infections, including sinus, and also for UTI/kidney infections. I am beyond grateful there's at least one medication like this one I can tolerate."

"Cefdinir did what no other antibiotic did as for getting rid of certain problems that I had for years. However, I had severe cramping and diarrhea with this medicine and had to quit taking it. I feel like, if the doctors know something about this medicine, besides popping 2 a day, he or she should tell you. A person has to look on the internet how to take medicines in order to keep down the side effects. And if my doctor told me it would be better to take Cefdinir on a full stomach and eat yogurt every day, maybe the side effects would have been much less. And he knows how sensitive I am to medicines."

"Took this medication twice a day for 10 days for infection of sinuses and adenoids. First three days my stomach hurt and headaches. Remainder of the days no side effects until the day I stopped taking it developed diarrhea and severe stomach cramping that didn't go away. 5 days after stopping the med now positive for C DIFF. I even took probiotics through the entire course of the med. Getting married in a week. Thanks a lot Cefdinir. I wanted everyone to be aware of this!!!!"

Omnicef (cefdinir) "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."

"I was prescribed this medication for sinus infection and fluid in ear. I have on my charts that I am allergic to penicillin but not sure of reaction. So doctor said this has 1% of penicillin derivative. So I tried it! First 2 days sinus seemed to get better. Then 6, and 7th day I had horrible a headache, ear aches, facial skin burning, chills and sweats. I couldn't lift my head off pillow. Took myself off the medicine and next day I was feeling better. Still have a lot of congestion but the pain in my head is gone. I feel like my head was deflated. This has to be an allergy! I learned my lesson."

"On cefdinir from day 1 to day ten. Severe weakness and tiredness. Seemed to clear up my sinus infection but then gave me a cold with stuffy nose and sore throat, and a bad yeast infection. Worst antibiotic I have ever taken, wish my doctor had told me about the side effects. Much worse than enduring a sinus infection."

"My six month old had two doses before we had to stop due to GI issues. Over a week later and she still has painful gas and diarrhea. We're tired because she doesn't sleep well. Cefdinir should be illegal."

"DO NOT TAKE THIS MEDICINE. I REPEAT, DO NOT. I had a cold that turned into a sinus infection and was prescribed cefdinir to take twice a day for ten days. I’m allergic to amoxicillin but my doctor said it should be okay because it’s never been a serious reaction. I started the antibiotics Monday night and it’s Saturday now. So I took pill 10 out of 20. Within an hour of taking it, I had diarrhea and didn’t think a lot of it because it wasn’t horrible and I didn’t feel sick. Well I’m five hours later and multiple trips to the bathroom with horrible cramps and loose, mucus stool and I feel like death is washing over me. I called my doctor and she suggested a probiotic but I told her I was not finishing it. Praying the symptoms go away with time. This happened to a family member as well. please save your body and do not take this medicine."

"I am a Scuba diver and have had fluid in my ear almost a month so I finally went to the doctor so that I could get something to clear up the fluid for a dive trip coming up. No OTC things were helping. They said I have a sinus infection (although I felt completely fine, I was just annoyed with having fluid in my ear for so long and knew it would cause problems when I went diving). I started taking it though. I have not had any of the side effects others are mentioning in the comments, but I have been feeling worse and worse with each day. The fluid finally cleared up after taking it for 7 days but it's day 9 now and I'm fatigued, throat hurts, appetite is gone. That has been getting worse with each day. I'm going to finish it up and then wait a few days before going back to see a different doctor. I wouldn't recommend taking this medicine and will be telling anyone in the future to prescribe me anything but this."

"I have chronic sinusitis, allergies and asthma and usually get a debilitating acute sinus infection every winter. I went to urgent care when I woke with extremely swollen tonsils, a dry but persistent cough and HORRIBLE facial pain everywhere due to an overnight maxillary sinus infection. Was put on Cefdinir for 10 days. I developed terrible bronchitis after the 2nd day on the antibiotic which I'm not sure is normal or not but the sinus infection actually seemed worse by day 5. Today is day 7 and I’m blowing my nose around the clock like I have been all week but my ears are still completely blocked, sinuses are still not clear, I’ve developed nosebleeds with the migraines and I am pretty sure the bronchitis has progressed to pneumonia. I’m dizzy and out of it and it burns terribly to breathe and the echo from my cough could go on for miles. Going to wait til day 10 but if the coughing with dark green mucous gets any worse I’ll have no choice but to ask for a second antibiotic."

"Doctor put me on this medicine for first time for a sinus infection. First day seem better. Second day all symptoms returned painful headache fever and chills. On seventh day went back to doctors, told her medicine wasn't working. She is running a TB test. Chest X-rays. Blood work and HIV test. Also changed to amoxicillin, it always worked before. Stopped taking cefdinir and already feeling better. "

"I had taken this drug in the past, it made me vomit violently and diahreah. When it was prescribed for me recently I had forgotten that this was the drug that made me so sick. I took one capsule and within 3 hours was violently ill, massive diareah and vomiting...I was alone and could not even get to my phone for help, I layed on the floor of my shower for hours having episode after episode. It is nearlly 24 hours after taking it and I am in such a weakened state I will not be getting out of bed. I feel I probably should have called 911 and gone to the hospital, I still am so dehidrated. This is an evil drug!"

This was unlike any other episode. Hospitalized for 3 days! Dr brushed it off as flu! Tried a dose last night for new sinus infection and Severe cramping and vomiting started within 3 hours of 1 dose! I will refuse this medication in the future!"

"I was prescribed a 10-day dose of this horrific medication. By day 3, I was having diarrhea at least 10 times a day. I stopped taking it on day 5 after experiencing a terrible headache and intense joint pain, neither of which could by relieved by over the counter pain killers. That was 3 months ago and I'm still not back to normal. I still have frequent bouts of diarrhea. My doc assures me it will go away with time and probiotics, but 3 months of diarrhea is too serious a side effect in my opinion. Also, this medication cost me over $50. Most other antibiotics are either free or cost a lot less than this poison!"

"Sinus infection right now. I was given Cefdiner to take twice daily. I'd never taken it before but I do not like it. I swear it's making me dehydrated, tired, itchy, diarrhea the first 2 days, lots of side effects. I've taken amoxicillin before so I am not sure why I was given this drug. My doctor told my to continue taking it for now. I have 4 days remaining but I'm done with it. Oh and my head still hurt, not as bad as it was but it's still there."

"If I could give this a 0 or a negative score I would! I was prescribed this medication for a sinus infection. After the very first dose, my body was in horrible pain to the point of tears. The following two days I took it I had body aches, extreme fatigue, and a depressed mood. The kicker was the third day when I woke up actively suicidal wanting to end my life. I haven’t had suicide ideation for a long while and it immediately started after taking this med. Once I stopped, the suicide ideation went away. I will never take this medication again, steer clear."

"My 11 yr old daughter had a sinus infection and was prescribed 300mg 2 times a day. Within an hr of the first dose she became VERY ill. Turned Pamela white and eyes dialled as if she were going to pass out. I called the dr immediately and they said the effects would pass. We discontinued immediately and was prescribed a different antibiotic and she was fine. This drug is horrible and can't believe it's still being used."

"I was given Cefdinir 300mg for a sinus infection. After the 3rd pill, I woke up the next morning with vertigo so bad that I was unable to walk to the bathroom - I had to crawl on hands and knees. For more than 24 hours, I was almost completely bed bound with waves of nausea and vertigo so severe that simply rotating my head just a few degrees on my pillow sent the room spinning. I felt like I was dying. Almost 2 years later, I am still suffering from vertigo. Needless to say, I did not finish the prescription."

"I am on my 4th day of the pill and although my sinusitis is almost 100% gone, I have the worst diarrhea I've ever experienced in my life. I cannot be away from the bathroom for more than 30min-an hour. I feel better physically, but this side effect is one to look out for."

"No side effects at all until my 4th day. I got horrible pain in my leg when going for a 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 had horrible wide spread body aches, felt like I had the flu. Red rash that lasted a few hours on my face. I'm a 33 yr 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 guess thats better than not being able to walk and feeling like I've been hit by a truck."
