I'm not going crazy...and neither is my child?! I was seriously considering taking him to see a psychiatrist until I read these posts! My 3 yr old took a 10 day round of Omnicef. During that time he had serious mood changes which I had pretty much determined were related to the Omnicef (although my dr said it he'd never heard of that) - severe temper tantrums at the drop of a hat (more so than usual), actually bit a child at school and was just plain mean. Just to be on the safe side I had already planned on not putting him on Omnicef again. THEN I came across this site. He has also had several other "issues" over the last couple weeks that I thought were unrelated - just a run of bad luck or something. However, every one of them is on here as something that someone else has also experienced while on Omnicef: waking up crying during the night - inconsolable and won't tell you what's wrong, mysterious rash on his back, and wetting his pants after being potty trained for some time. I can't believe it. I had even taken a urine sample in to the dr sure he had a UTI (negative of course). Also it may be helpful to note that some of my child's side effects developed the week after he stopped taking the medicine, so I think it takes a while to get out of their systems.
I know that there are lots of children out there that have taken this antibiotic with great results. However, mine will never take it again and I wish doctors and pharmacists were more aware that these problems do exist.

My 18 year old daughter had a terrible allergic reaction to omnicef 2 weeks ago after a 10 day regimen. Sadly, it happened 2 weeks after my nephew had an allergic reaction to the same medicine. His situation did not end so well. He was taking the medicine for strep. The allergic reaction started with hives and got worse. After some aggressive research on my brother and sister-in-law's part, my nephew was diagnosed with an allergic reaction to omnicef followed by rheumatic fever. I should have refused the omnicef for my daughter, but who knew.
My daughter is 2 weeks into annoying hives that continue to pop up in different places. Her feet are swollen and we are very concerned. She has taken steroids, Kenelog cream, benadryl, as well as prescription strength antihistamines. Tomorrow she is going to see another doctor to find out what is going on. Cefdinir/omnicef is no longer welcome in our extended family.

After 8 days of taking Omnicef I developed a bright, red rash on my legs, arms and stomach. Skin is peeling between my thighs. Also noticed that my joints are stiff and I am lacking stamina not only from the pneumonia but from the side effects of Omnicef.

My son Emmett was put on Omnicef for pneumonia and ear infection. On the second day of being on this drug he had terrible diarrhea, black and watery and he would scream every time he was pooping. He wouldn't sit and would cry if you tried to lay him down to change him-this made me think his stomach hurt pretty bad. Sometimes he would stand there and look at his stomach and just scream. On day 10 of Omnicef he had something on his stomach develop that looked like a heat rash that started off as white bumps then turned red. Two days later (2 days after the drug was all taken) the bumps became bright red and were everywhere. He also had swollen knees that were hot to the touch and wouldn't walk around. We went to the doctor and he said it was a reaction to something he ingested. He said we should give him Benadryl and just watch him. The Benadryl worked for a couple days then stopped working all together. New red spots would come back as soon as the others went away. Three days later we were headed to the ER because of swollen feet, all of his toes connected and his feet were so puffy he wouldn't stand on them, they were also hot to the touch. Luckily we saw a different doctor and he did some blood tests. It turned out he had mycoplasma infection which is also knows as walking pneumonia. He was given Zithromax and was better within 12 hours. The red spots and bumps and swollen extremities were all cleared up. I don't know if he was allergic to Omnicef because he is allergic to Penicillin or if he was just given the wrong drug for the walking pneumonia and it wasn't getting any better. It is definitely worth getting a second opinion in the same day after going through this last week.

My son has had 3 night terrors in the past 2 years. This is such a horrific experience for a parent and I can't imagine what the child must be going through, but my son is in such a panic state when this occurs that you can't do anything to help him. All I can do is keep trying to talk to him until he comes around. He never remembers the episode thank God!! I just realized last night that there might be a link to him taking Omnicef and these night terrors. He hasn't had one for awhile til last night and he had two doses of Omnicef yesterday for an upper respiratory infection. After reading this morning about others who have had this same experience, I will not be giving my son this medicine again. Hopefully this medicine has been the cause and the night terrors will be over.

Has anyone noticed incontinence as a side effect in toddlers? My 3 year old has been potty trained for quite some time now but today he has wet himself 4 times. He's not had any accidents in months. This is also his third day on Omnicef. I'm hesitant to put a pull up on him because I don't want to set him back in his potty training.

My son was given Omnicef to treat an ear infection one day before his first birthday in 2003. The next morning after his first dose he woke up covered from head to toe in a horrible rash. His eyes were swollen almost completely shut, and he was "zoned" out. He obviously was in lots of pain and very cranky and couldn't sleep. We took him to the ER twice, first time the doctor said he must be allergic to the Omnicef but isn't experiencing any discomfort. Several hours later, well after midnight, he still was very cranky and couldn't sleep and we took him back to the ER where the doctor gave him an injection of Benadryl. My son from that point was very "difficult", horrible melt-downs, no eye-contact, no communication, except for his violent melt-downs. This lasted for years.

I am a 42 year old male who was put on a 600mg 21 day course of Omnicef along with 7 days of Prednisone for a recurrent sinus infection. Augmentin had failed and Avelox was a horror show. After 10 ten days of virtually no side effects I am now totally constipated and bloated to the point my pants don't fit. Also my stomach is constantly rumbling and gassy. I should add that it has done ZERO for my sinus infection. I have been taking pro-biotics everyday. I am now afraid to eat anything and scared of using an enema as I might kill whatever beneficial intestinal flora I have left. It seems to me that besides the "old standards", the new line anti-biotics are just evil. Unfortunately doctors and most Americans over prescribe and over use anti-biotics to the point where we now have to rely on these harsh new drugs. Stop using anti-bacterial hand washes!! Soap is just as good!

I was started last Thursday for sinus infection. I ended up in ER on Sunday with what I thought was a migraine headache with nausea and vomiting. Which I have a history of. Thank God the doctor on call did not give me the normal shot which I usually get and send me home. He was did blood work and found out the my liver function test was so high that it was not safe for me to go home so I spent two days in the hospital to get my liver functions back to safest enough level to send me home. And they are not normal yet. So be ware of this meds or any meds that it is related to

My 3 month old son was prescribed Omnicef for an ear infection, once a day for ten days. I was on the same drug for a sinus infection and the doctor felt that since I was breast feeding the baby and I should be on the same drug. First dose was Sunday night. On Monday my son developed red spots on his legs. On Tuesday he woke up with a rash all over his face/ears/neck basically all over his body. It progressively got worse that day with his eye lids swelling, and his hands being swollen. The Dr. took him immediately off the antibiotic and prescribed Benadryl every 6 hours. By Thursday the rash started to go away and on Friday he was rash free. The rash on his body was a mixture of a "flat" rash and a "raised" rash. No other symptoms and was a very happy child eating and sleeping normal. I was freaking out because he just looked awful, like he was sunburned all over body. Now I want to know if this will be a permanent reaction or something he will out grow? Pharm said Omnicef is a good drug and one that the newer drugs are being developed off of. J.

Our son has a non-allergic rash to penicillin at age 1, so he was put on zithromax to cure his bronchitis. Since then, he's had no antibiotics. Until last week, at age 6-and-a-half, when the doctor diagnosed an ear infection. He's been on Omnicef for a week, and has been very irritable! Flies off the handle at any moment, growls at his siblings... he has just generally lost the ability to "deal" with things. Our younger son has been on Omnicef twice for ear infections, and has had NO adverse reactions to it, other than some very loose stool, which is almost expected. I guess it works differently for each person!

My 2 year old daughter has had similar experiences on Omnicef. She was prescribed it for an ear infection on Wednesday, by Thursday afternoon she was inconsolable. Normally, she goes to bed at night with no problems and sleeps straight through to 8 am. It took about 2 hours to get her to calm down enough to lie down, then we had to let her cry before she finally went to sleep. She woke at 5am the next morning and cried for 2.5 hours saying 'No, no, no' even though we weren't asking her to do anything or have anything. Then she refused all food, drink, rocking, etc. She seemed as if she was having a night terror while completely awake for 2 + hours. I agree that more research should be done on this drug.

My daughter is 18 months old. She has a bad ear infection that doctor thinks that it is lingering since it has started a month ago. Omnicef was her 3rd dose of antibiotics that we tried after amoxicillin and augmentin. After her 2nd dose she started getting red in her cheeks and had loose bowels, after 4th dose she was covered with hives and rash all over her body, worst on her cheeks. After taking her to the doctors office, we were told that she has allergic reaction to omnicef. She was given benadryl (4x 1tspn per day),doctor said it might take a week for the rash to disappear and for the ear infection she was prescribed with zithromax ( 1tspn per day for 3 days). If anybody has experience with this kind of problem, I would appreciate some feedback.

I AM A 42 YR OLD WOMAN WHO JUST FOUND OUT I AM PREGNANT. A WEEK PRIOR TO FINDING OUT I HAVE HAD CRAMPING, THOUGHT IT MIGHT BE TUBAL SO I WENT TO THE HOSPITAL AND EVERYTHING WAS RIGHT WHERE IT WAS SUPPOSE TO BE. HOWEVER, THE DOCTOR ON CALL SAID THAT I HAD A SMALL INFECTION IN THE LOWER REGION AND PRESCRIBED THIS OMNICEF. IT HAS BEEN GOING ON 4 DAYS NOW SINCE STARTED TAKING THIS DRUG AND I DON'T KNOW IF THE INFECTION HAS CLEARED BUT I KNOW THE CRAMPS ARE STILL THERE AND I HAVE THE DIS-COLORED STOOLS LIKE EVERYONE ELSE...AFTER READING 2 PAGES OF TESTIMONIES, I HAVE DECIDED TO STOP TAKING THIS DRUG IN FEAR THAT IT MIGHT DO SOMETHING TO HARM MY UNBORN CHILD.

my 9 month old was put on this medication for an ear infection last week. 24 hours after taking the first does she began throwing up and continued for 3 days doing that. I finally stopped giving it to her once I figured it was the medication causing her to throw up and called her doctor and have asked for something different. She is obviously allergic to it. She also had bad diarrhea and became dehydrated almost to the point that I was about to take her to the ER. I don't like this drug at all!

I'm a sixteen-year-old girl and I was put on Amoxacillin after the doctor said I had Bronchitis, along with liquid codeine.. The codeine caused me to pass out less than 4 hours after first dose. Along with passing out I also went blind for about 20 minutes and couldn't hear. When I didn't get better from that my doctor prescribed me Omnicef. I threw up the next day after taking it and I also am constantly nauseous and sleep way too much. I am really tired all the time too, no matter how much I sleep. And my 'private area' smells like alcohol. I also am having back and lower pelvic pain. This is ridiculous. Screw this drug. The FDA should NOT have okay'd it. Anyone else have these problems?

I took 500 mg of Omnicef and then had a bowl of ice cream. About 5 hours later I became violently ill with vomiting, nausea and light headedness. I thought I had food poisoning. A week later, I did the same thing, had the same reaction and realized it was the combination of Omnicef and the ice cream (just happened to be a different kind of ice cream too).

Do NOT take omnicef and anything with calcium, including ICE CREAM!

My 11 year old daughter took 2 doses of omnicef for a bacterial infection in her throat. A few hours after the second dose she complained of severe pain inside her mouth (roof of mouth gums were bright red around her teeth) sais is feels like she has acid in her mouth.. Took her back to doctor they said this could not be a side affect. Called pharmacy they told me yes this could be a side affect but RARE. It is going on three days since the second dose (stopped after complaint) and she still cannot eat or drink much because of the pain in her mouth. We are going to the dentist to see if they can help. Has anyone experienced this type of side affect.

i'm a 19 year old college student, and i'm on my last 3 days of this medication, and while i had bad side effects at first, i waited them out, and now they're mostly gone. i had stomach cramps, that gassy feeling, i was dizzy and felt faint...i felt like i was in a cloud and couldn't function. however, it was better than the misery i was experiencing from the sinus infection, where i was only able to sleep. i can return to work, and some side effects still linger , but its def. done its job as an antibiotic. i did develop a yeast infection from the antibiotic i took before omnicef, which is why i didn't want to change medicines again. i was on another antibiotic, which made me deathly sick. omnicef is supposed to have less severe side effects than other bacterial infection antibiotics out there. i did take a probiotic with the omnicef, i recommend taking one with any antibiotic. it levels out your bacteria levels, which may stop stomach problems altogether.

I was diagnosed with severe sinusitis a week ago, and my doctor prescribed omnicef for me since I was allergic to PENICILLIN. After the first day on Omnicef, I felt fine, perhaps a little better. As days continued to pass, however, I began to get some horrible reactions. They started out mild, and now (after taking it for the seventh day) I have major tongue and gland swelling in addition to a horrible headache and weakness. I've felt close to fainting several times throughout the past several days. I went through a random bout of depression a couple days ago, too, and there was no reason why. I feel more irritable, but I've been attempting to control it. I haven't lashed out wrongly at my loved ones yet, but I've come pretty close. I have some pain in my lower abdomen (where the intestines are located) as well, but only when I walk in a quick manner. No diarrhea, yet, but I think that's because I normally have digestion problems (constipation). Some of the joints in my hands are acting funny. They aren't as strong as usual, and they've been going numb/cold more often, causing their movements to be a little slower/stalled.

I'm seventeen, and when my mom contacted the doctor yesterday, the doctor said that "these aren't allergies/side effects" of this medication, and that I need to continue taking them. So I took them again yesterday (the seventh day), and that's when the swelling of the tongue and glands in my throat took place. When my mom called today and notified the doctor of that issue, the doctor said that..oh, how was that worded... That "it's the first time I've had this reaction" (while on this medication), and that it isn't caused by that medication but from something else. I'm sorry, but I'm not taking any other medications, and I haven't eaten anything strange/new that would cause me these difficulties. It's definitely the medication.

I'm done with this medication. After doing research on it this morning, I've learned that at least ten percent of those allergic to penicillin is also allergic to omnicef, and I'm allergic to penicillin. Why my doctor is being so stubborn about these reactions, I don't know. I guess this is just an example of a doctor who isn't well-educated and sticks ONLY to the side-effects/allergic reactions listed on the prescription bottle. If problems persist, my mom will take me to another doctor. For now, I'm going to stick to the Neti pod and nasal spray to try to rid me of my sinusitis. Maybe it'll work out alright and my problems from this medication will go away quickly. I'm sick of being sick all summer.

I was given omnicef for a sinus infection, though I was told to take it twice a day , ive only been taking it once a day , due to an unnormal schedule... It has caused me to be so uncomfortable..I cant stand it. I have unbelievable abdominal pain, cramps ... but no diarrhea... Im constipated , one bowel movement a day ... and I also have the rust/ red stools. which is a listed side effect . Ironically, Before being diagnosed with all of this, I was in the doctors office a few weeks earlier complaining of stomach problems. . thinking I may have an ulcer, and my doctor told me It was only stress... yet he never tested me for an ulcer, no x-ray , nor an endoscopy. Now Im on some medicine that apparently may mess me up even more. WOW.

(33yr) Was given Omnicef for an ear infection. After 3rd dose broke out with huge patches of red whelps. Stop taking, but then my joints started to ache and I had large knots on the bottom of my feet and hands. Diarrhea and vomiting, severe stomache cramps and low blood pressure... followed by antiphylatic shock. While I was in the ER the discovered I was also having a heart attack.

It has been 3 weeks and every time I come off the steroids, the rash and other symtoms return.

Has anyone else had similar problems.

My 9 month little girl took omnicef and developed a rash after her second dose. I took her to the doctor - they thought she had either roseola or hand foot and mouth.....By the time I got her home that afternoon and some time had passed - it developed more and looked awful. I called the doctor back and she informed me that with roseola or hand, foot and mouth it would get worse before it got better. That night my baby was very uncomfortable, could not sleep and kept trying to scratch the rash through . The next morning, I called the doctor back because by this time she looked like she had a horrible sunburn and it continued to worsen. The pediatrician then thought she was having a reaction, suggested benadryl for two days and then switched her to augmentin. We will begin taking that tomorrow morning - I am a little nervous because I hope not only that it will work but that she will not have any side effects like she had with ominicef. As far as taking omnicef, my other children have taken it and they were fine -but as for my baby I had it documented on her chart at the doctors office and at the pharmacist so that they will stay away from all medicines that are in the omnicef family. I hope that I will never have to see this again nor deal with it. Jenifer

My 4 year old daughter was on omnicef for two days for an ear infection. She is now covered from head to toe in a nasty red rash. The rash on her cheeks looks as though the bumps have all meshed into one huge red bump. Her entire cheeks are bright red. The dr said it was an allergic reaction to the meds and changed her to Septra. I don't want to start her new meds until the rash is gone but it isn't showing signs of improvement as of day 3. I am wondering if anyone could tell me how long the rash lasts? Should I start her new meds for the ear infection anyway? And she is sooooo moody. Her meltdowns are on a nuclear level which is out of character.

Went to the doctor week and half ago for flu and found out that i had ear infection and bronchitis also.. Dr. prescribed omnicef this time.. (300mg - two pills once a day) and i took the 10 day course.. infection somewhat cleared.. but i had tremendous stomach cramps and loose stools, gas, bloating, etc.. I thought that those effects might have been part of my flu... and after being off the antibiotic for 3-4 days, they started to go away.. so.. went to the doctor two days ago and she wanted me to do another 10 day course of the omnicef to finish clearing up my ear infection and bronchitis.. the same night i started this course.. (last night).. i immediately had the stomach cramps, gas, etc.. all over again.. i am convinced it is this antibiotic and will be calling the doc in the morning.. i AM NOT taking any more of this stuff.. the side effects are debilitating

My 4 yr old is on it now and after reading all of your comments I am able to see similar side effects in my girl. Initially, she had diarrhea but it cleared up after two days and a lot of pro-biotics. Then we began to notice how excessively tried and drawn she was. Looking back on this last week she has also been irritable. I had attributed it all to her being sick, possibly the change in season but now I'm thinking it was this antibiotic.

My 1 year old was prescribed Omnicef for a possible sinus infection. Before she started taking this med she had a little cough and a runny nose, not that bad at all. The doctor thought she should go on this for 14 days to help. She has been on the med for 4 days, and her symptoms have gotten worse. She is coughing all the time, she is having massive maroon colored runny stools, and she has a horrible diaper rash. She has started to get a welt on her thigh, and rash around her cheeks and chin. I am currently waiting for the doctor to call us back regarding the problems she is having. I am so glad I found this website, and know that I am not being paranoid. My daughter is the most even keeled baby you will ever meet, but the last couple of days she has been crying all the time as if she is in pain. I have stopped the medication and will never allow her to take this medicine again!!!!

Be aware that "Brick Red Stools" in children can suggest a bleed from Mackel's diverticulum and hence must be referred to a paediatrician. Mackel's diverticulum is a congenital condition. The bleeding usually settles on its own but very rarely the child can become severely anaemic and may need a blood transfusion. Surgical intervention also is very rare.

My doctor gave me omnicef for a sinus infection and I must say that I felt much better before the I started the medicine. From the first day I had most of all the side effects, nausea, diarrhea, vomiting, no appetite, but no muscle/joint pain. However, since I finished the last pill, I have been experiencing extreme right leg pain in the hamstring area and below. Actually, my whole leg hurts like heck! I have been doing leg exercises and taking ibuprofen, but how long must I do this. It has been going on for 2 1/2 weeks now. I too will never take this medicine again. I am not even sure that it even helped my sinus situation, but if it did, it also caused way more problems than I had or ever expected.

My kids have both taken Omnicef in the past and they are on it now again. They are 5 and 2.5 years old. The biggest thing I have noticed is that their behavior has changed. They are quick to go into meltdowns and cry very easily. They do not get along as well as they usually do. There is no doubt that this medication is the cause. My 2.5 year old is finished as of today but my 5 year old has 4 more days to go.

Received script for 300mg 2x per day for 10 days to treat ear infection and sever chest congestion. At the time the only side effect was sensitive skin & lots of itching, combined with a very mild diarrhea. Here is the crazy thing: now that it has been 30-40 days since I was on the antibiotic, my toe nails have grown out and you can see that it has killed the old nail in front of the new growth. My brother is a physician & he said it is weird, but not out of the question.

My five year old was in the hospital for 4 days for a sinus infection and they put her on Omnicef. My daughter is a very cheerful little girl and these last couple of days she has been everything but cheerful. Its as she has turned into a demon over night. She has been having the worst mood swings. She has been screaming, yelling back, and kicking her legs and just being really mean. I remember the nurse advising me the possibility of a change in mood swings but I never imagined this. Omnicef did it's purpose BUT I hope to never have to use it again. I was not prepared for the mood swings my child acted out. I thought it was just my child until I started reading online and asking around.

Our 3 year old son took Omnicef starting on a Friday. By Sunday, we were at the end of our rope. He was screaming constantly, we could not get him to go to sleep, he started being VERY aggressive.... kicking growling, hitting and just acting out in ways we'd never seen. My husband finally started looking online after our son had a fit and screamed in a corner of our house for 30 minutes, then looked at us and started laughing and acting like nothing had happened. We found this web site, and to our relief, realized our son was not just acting out. I have NO DOUBT it was the antibiotic and I can't believe this medicine made it onto the market!!! I threw the bottle away and intend to talk to our pediatrician asap.

My 6 year old daughter was prescribed Omnicef for a upper respiratory infection.She took it for the prescribed time of 7 days with no problem,I thought.One day after she was done with the Omnicef she broke out into an awful rash,head to toe. Not thinking it had anything to do with the Omnicef,I took her to the ER.The Dr. said that this was an allergic reaction to Omnicef,even though it took 8 days to show itself. After reading some of the other post I remembered that she also hasn't been sleeping well.She woke up screaming on night and said that someone was in the bed with her.It all makes sense now.My child will never take this med. again!

My child was prescribed Omnicef for an ear infection on Tuesday and we ended up taking him off on Friday night. He is normally a happy, hyper, normal 3 yr old but he became very mean!! We didn't know what was going on with him. We just thought that maybe he was acting out, until we talked to some one who knows about food allergies who asked if anything was different in his diet. The only thing that was different was he started this new anti-biotic. He had an allergic reaction to Amoxicillin and we told the doctor. but he still put him on this medication anyway. Our son changed so much in this last week it is just unbelievable. On the second day of this medication he actually tried to bite some older gentleman at a dental clinic. Just not his normal behavior. He didn't sleep well, would literally kick, hit, punch, pinch and bite us and his siblings. Since we took him off this medicine he is finally acting like his normal only self. We had not realized until he started to giggle about something that he had not laughed since he started his medicine. There is no way that he will ever take this medicine again and after reading all the information on OMNICEF I do not understand why they keep pushing this drug since there are so many harmful side effects (half of which they do not list)!! I just hope that this has not done any other damage to my son internally as well...

Has anyone had any chest pain from taking Omnicef? I've had a dull very mild pain in my chest by my heart that comes and goes. I have no trouble breathing. I was on the drug for over a week and didn't really notice the chest pain because of all the coughing I was doing from my sinus infection. It wasn't till three days after I finished taking the drugs that the pain became more frequent. Has any one felt this?

I have had rectal bleeding for the last 3 days. I saw the doctor who referred me for a coloscopy after I complained. No information on how to stop this or why I'm bleeding. Also very bad heartburn and depression. Gee, who wouldn't be depressed if they saw blood from their anus?
I'd rather have bronchitis, thank you very much.

I'd like to start off by saying though many people have had some very bad reactions to this medication, that it is not a reason for it to be taken off the market. everyones body's have different reactions to different medications and while for some it may be a very negative reaction, for others it may be a very good or significant one. I'm 17 years old and currently taking Omnicef for a sinus infection. I am having side effects but the fact is a few days ago I was miserably sick, and now I am feeling significantly better. so though I am having side effects, the benefit of this medication, or at least for me, is that my sinus infection is most definitely getting better. my side effects have been gas and nausea (which I usually have regardless from GERD), bad dreams and restless sleep, and this is quite odd but fowl smelling urine and body odor. I haven't read about anyone else noticing body odor after taking it though so if someone has noticed this can you please let me know? thank you.

My one year old daughter was prescribed this medication 4 days ago for an ear infection. I will never give her this medication again. Over the course of 4 days she developed worsening gastrointestinal symptoms similar to a stomach flu including diarrhea and vomiting. Today she projectile vomited all day long and was unable to keep down food or liquids. I called the pediatrician who informed us to cease using the medication immediately. Using Omnicef has been a horrible experience.

My son was diagnosed with his first ear infection at 12 months old. He was prescribed Amoxicillin, but broke out in an allergic rash. We were then prescribed Omnicef ($50 WITH insurance!). He wasn't even on it for 24 hours and started vomiting anything and everything he put in his stomach. I gave him about a day to see if it was a stomach virus, but it continued. I called the doctor's office who told me to take him off the Omnicef and see if the vomiting continued. Within 24 hours, all vomiting stopped, so I called the doctor's office back and was given our 3rd and final antibiotic...Zithromax...which was the cheapest of the three.

My 19 month old was hospitalized for 3 days with a high fever and all the symptoms that go with ...ie: body ache, fatigue, loss of appetite, dehydration. this took place after a 10 day amoxicillin course. In the hospital they started Omnicef via iv. after getting home he seemed to slowly get back to himself, with a few issues...waking up with "night terrors" cranky, loud, clingy, loose stools. his fever was down but not gone and his cough and runny nose seemed to be getting better. that is until today. we are 8 days into a 10 day with Omnicef and today his fever has returned (back up to 101 to 102) and his nose is running again. so 2 antibiotics down what next. between, all tests in the hospital came back negative until the blood culture came back and determined a blood infection. I am calling the hospital pediatric doctor in the morning to report on his repeat symptoms

Now I know that I am not going crazy! I am a 42 year old woman diagnosed with strep throat last week...I was prescribed Omnicef for 10 days...300 mg twice daily.
I have had horrible stomach cramps, severe debilitating muscle aches, no energy at all, don't feel like getting out of bed, let alone going to work. I have been very moody, downright evil to my family...and I didn't know why. Today I was in such bad shape that I told my husband that I must have something bad wrong with me, like cancer, because I felt like I was dying. I am NOT taking my last 4 doses...I just hope it gets out of my system by Monday. Thanks for this site....I have hope now.

My 6 mos. old daughter has been on Omnicef for about 3-4 days now, AND she is also dealing with some constipation...today she had about 3 clay like stools that were red-orange and then tonight another one was completely brick red/maroon. It didn't really look like a typical bloody stool, but I was nervous due to her constipation and straining when trying to get it out. I called the triage nurse and she said it was from the Omnicef...thank God she's not actually bleeding!

It was very alarming though, and we almost went to the ER. Hopefully her resp. infection and constipation will subside and she will get to feeling better soon!
