For Bacterial Infection "Two hours after taking the first dose of Augmentin, my son started vomiting every 5 minutes for 2 hours straight. It got to the point where it became so violent that he started vomiting blood, which I saw was indeed a side effect of the drug. I had to take him to the ER to stop the vomiting and get him hydrated. It was a nightmare! The next day, he had the most severe diarrhea he's ever had, all with just one dose. He did take it with food."

For Sinusitis "I would NEVER recommend this drug to ANYONE! Took 1 pill about 3 hours before bed. Finally got to bed at 3 am and lay there for an hour with such nausea I had to get up. Tried to take some Pepto-Bismol for it, and no sooner than I took it, I got violently ill! I was vomiting the rest of the night until around 6 am. I have no problem at all with taking regular Amoxicillin, so whatever else is in here, my body rejects it strongly! One minute I'd be sweating like it was 120 degrees, the next I'd have the chills so bad it felt like I was outside with shorts and a tank top on in the middle of winter (like now). NEVER AGAIN! Stay as far away from this drug as possible!"

For Sinusitis "3 hours after my first dose of Augmentin 875, I started vomiting in addition to diarrhea. I thought I had a stomach flu. I waited 5-6 days to restart the antibiotic. Well, 3 hours after that dose, guess where I was, in the bathroom vomiting again for several hours! I will NEVER take this medicine again!!! I've had Augmentin before but only experienced nausea. Not anymore! :("

For Sinusitis "After a couple of hours after taking an 875 mg tab, my stomach became rock hard. I had the most debilitating stomach cramps known to man. I've never vomited as much and as hard as I did that day. The diarrhea was like I was urinating out of my anus. After drinking a bottle of kefir, I was good again."

For Sinusitis "I am currently staying in the hospital overnight with an infected colon (thought it was appendicitis, it was so close), crazy watery diarrhea, vomiting, severe stomach cramps, and therefore dehydration. I have never had digestive problems like this, and I've never been in a hospital overnight. This is seriously because of Augmentin. Do not take this drug!"

For Strep Throat "This cleared my throat infection within 2 days and made me feel so much better pretty quickly as far as temperature and discomfort were concerned. However, I did vomit with it and felt nauseous for about an hour and a half after taking it. The diarrhea is still with me on day 4."

For Sinusitis "Started on 100 mg of Augmentin for sinus infection. Cleared up sinuses well but had severe diarrhea. I wasn't concerned by this considering it's the common side effect, but I just took my last dose. Not four hours later, I threw up twice and had more bowel movements. This medication was not for me."

For Sinusitis "I was diagnosed 7 days ago with a sinus and ear infection. I had vertigo, terrible throat pain, exhausted. After about two days of Augmentin, the pain went away, and I started feeling better. I’m no longer dizzy, having throat and sinus pain or draining in my ear. However, I decided to stop 4 days short of my 10-day course because I’m having AWFUL side effects. Worst abdominal pain ever, constipation, fatigue, nausea, vomiting, back, hip, and leg pain. This doesn’t seem normal. Hoping my sinuses and ear are healed enough, or I’ll be back to the doctor for a different medication."

For Sinusitis "First dose with dinner. Went to bed about 2 hrs later, woke suddenly, barely able to make it to the bathroom, began vomiting, then couldn't get off the floor, too weak. Began shaking, son called ambulance and next thing I remember was seeing my dad in a chair beside my bed in the ER. Was on fluids, Dr. came in and gave me Demerol. I went to sleep and don't remember leaving the hospital or going home. That was the entire experience. Never been so violently ill. Still have no idea why it made me so sick."

For Sinusitis "As a sufferer of many sinus and ear infections, I knew with this 90-degree heat in ACs with poor air quality that I was going to get sick. Got sick last Wednesday with sinus issues, got worse, so went to the primary. The doctor said she didn't think I had a sinus or ear infection, so she told me to continue on neti pots and Sudafed 24. She did give me a prescription if I wasn't feeling better by Monday (today). After a weekend of still feeling miserable, I got the prescription. Usually, I get amoxicillin, and when I looked at the script, it had amoxicillin clav, so I didn't think anything of it. I pick up the script. Take the pill on the way to work. Sick within an hour. Googled and found I was given the generic of Augmentin. Never again! Threw up for an hour straight - not worth it!"

For Upper Respiratory Tract Infection "After one dose, I was in the ER. I was vomiting violently and became very confused. My husband said I kept asking the same questions over and over. I had memory loss and still can't remember the day I took the dose. I had an MRI and did not have a stroke, all other tests were normal. It might work well for some, but clearly it really affects others negatively."

For Bacterial Infection "Got a very deep cat bite and ended up getting a bad infection up my whole arm. I left the hospital and was in the emergency room the next day because after 2 doses and 24 hours it was actually spreading. After 48 hours, the swelling finally started to go down, which I was happy about, but I started getting severe side effects as well. Constant feeling of vomiting, complete loss of appetite, and slight to severe confusion. (Poured chips out of the bag onto the counter thinking I had a bowl out. And calling things by the wrong name constantly.)"

For Sinusitis "Took Augmentin for severe sinusitis. After 2 hours, started vomiting, it would not stop. Rushed to the medical center, given an injection to stop the vomiting, didn't work. Vomiting continued until only bile and blood was coming out. Then given Zofran wafers, finally, the vomiting subsided, but the stomach and chest pain continued all night. Worst experience :("

For Sinusitis "This is the 2nd time I have been Rx'd Augmentin. 2nd time I have been violently ill 2 hrs after taking it. Diarrhea, vomiting, stomach pains, and headache. Much to my husband's delight, I also have laryngitis from puking so violently."

For Bacterial Infection "I was prescribed Augmentin for a dental infection/tooth abscess. When I went to the dentist, I had already been on 3 or 4 days of penicillin. The penicillin didn't seem to be clearing the infection, and the dentist couldn't get me in for a root canal for another week. There, Augmentin came into play. The first dose I took on an empty stomach (couldn't eat with my throbbing face). So I had some nausea and just figured it was normal. The next dose I took with food, as directed. I puked viciously. I took another dose or two and had similar results... so much nausea and vomiting, it was hard to appreciate the fact my face wasn't throbbing. So it works well on infections, hard on the stomach though."

For Bronchitis "After just 2 doses of planned 10-day 2x/day 875 mg treatment, got violently ill, literally projectile vomited on brand new carpet as I couldn't get the 10 feet to the toilet fast enough. Stopped medicine immediately but still had massive, continuous diarrhea for almost 3 weeks, lost 17 lbs in 14 days! It was so bad/went on so long the doctor actually tested me for C. diff, which was negative. Will never, ever take this again!"

For Sinusitis "I was given Augmentin one time for an acute sinus infection, and even taking the medication right after I had eaten not only gave me bad diarrhea, but also I was throwing up with it. Our living room wasn't far from our bathroom, and I couldn't even make it to the bathroom. When I did, I was hanging my head, throwing up in the sink and sitting on the toilet with bad diarrhea. I make sure if I get a sinus infection, my doctor gives me Levaquin. Levaquin and Bactrim are the only two antibiotics that will clear up my sinus infections."

For Skin or Soft Tissue Infection "Don't know what's worse... the cellulitis infection or side effects of Augmentin. Headache, gassiness, bloating, stomach upset from day one. Horrible vomiting on day five. Thank goodness I only have a seven-day Rx. Calling the doctor tomorrow and will beg not to take the last two days or switch to something else."

For Upper Respiratory Tract Infection "This drug is awful. I have 3 days left, and I physically cannot handle it anymore. I'm intensely nauseous every day, but I never vomit. I just drool at the mouth and dry heave until it wears away. But by the time the nausea settles, it's time to take another pill! It makes going to work almost impossible. I also get unusual headaches and generally feel terrible. Unfortunately, it's a holiday, so I am unable to contact my doctor for something new. Considering risking it and quitting - never again."

For Sinusitis "I feel comforted reading the feedback on this because I thought maybe I was losing my mind. I have had sinus infections for years and finally tried the antibiotic approach. I had no idea the side effects would be so awful! Stay near a toilet or wear Depends. On day one, I 'sharted' in public, then started daily taking anti-D meds, which didn't even help. Vomited twice during the week, but that was probably me being bad for drinking alcohol. Horrible headaches, fatigue, and brain fog (to the point my boss asked me if I was okay just passing the hallway) and long bouts of weird fever-sleep. The worst part is, either I got a cold virus by chance, or this hasn't worked at all... it's hard to tell, but it feels more like a cold. Awful from start to end."

For Upper Respiratory Tract Infection "This medication, Augmentin, is absolutely horrible on me. I’ve been prescribed this twice. I’ve taken it with and without food, and both times I vomited violently to the point I was hospitalized. I became so dehydrated they couldn’t even get a urine sample by catheter. I sweated so badly my jeans and t-shirt took two days to air dry. I became so delirious from vomiting that I stripped naked in front of my mother and children, then passed out. She called the ambulance. I couldn’t handle a day's dosage either time."

For Bacterial Infection "Took an 825 mg dose with a little food as recommended. I ate a small dinner 3 hours after taking the first pill. I became very nauseated 2 hours later and vomited 4 times 3 hours after that. It’s now been 24 hours since I took the medicine, and I'm still queasy. I was given it after a root canal on my tooth. I’ve not vomited in my adult life, and I’m a senior. Bad stuff for me."

For Middle Ear Infections "I was prescribed Augmentin for healing my ear infection. I threw up shortly after taking the first dose. I felt dizzy and very unwell. I will never take this medicine again. I feel worse than I did before taking it. Amoxicillin by itself should do the trick without all the side effects of Augmentin."

For Skin or Soft Tissue Infection "After taking Augmentin, the very next day, I had the worst migraine of my life. I don’t know how I powered through school, but I did. The next day, the migraine was still very present. I woke up and vomited because my head was hurting so bad. I went back to the ER. They hospitalized me after that for four days. I had CT scans and everything. Worst experience ever on Augmentin, that is."

For Sinusitis "Don't ever use this. When I was 4 years old, I was sick, and the doctor gave me Augmentin. It affected me in a negative way, I used to throw up, pee (urinate) with blood, my skin was very pale, and my eyes were yellow, and it caused me severe liver problems."
