For Bacterial Infection "Taking Augmentin 875/125 2x daily prophylactically to prevent infection from a deep puncture cat bite. Five days in, there is no sign of infection, and everything appears to be healing fine. So, it seems to have potentially prevented infection. But wow, did it make me feel awful. Brain fog with difficulty focusing mentally and visually. No energy. Lots of nausea, lack of appetite, and generally feeling out of it. Diarrhea occurs without enough fiber. As others have said, I think it's increased my anxiety significantly. Haven't had any panic attacks for a long time, until this beauty. I'm not sure I'll ever know if it prevented an infection or not. I do know that it caused me to feel like absolute crud!"

For Bacterial Infection "I really like this antibiotic so far. I was on Cipro before for the same infection, and that made me feel nauseous and dizzy. With Augmentin, I feel fine as if I am not even taking an antibiotic. Lots of negative reviews on here, so it just shows you that everyone has a different reaction. Just know if an antibiotic makes you feel really ill, you should call your doctor right away to switch and should not keep taking something that you can't tolerate."

For Sinusitis "I had a severe sinus infection and went on Augmentin 875. It has helped. No more headache and facial pain. I was extremely dizzy, nauseous, had a loss of appetite, severe mood/personality changes, and hyperactivity. I went off the medicine on day 5, couldn't take the side effects."

For Sinusitis "I was prescribed 500 mg twice a day Augmentin for a sinus infection. After the second dose, I developed BAD stomach cramps, nausea, and loose stools. I continued the Augmentin for three more days, but finally had to stop taking it due to the fact that it was completely destroying my stomach. It was working wonders on my sinus infection, but the side effects were too much to bear. Worst of all, I'm still having cramps and loose stools even though I stopped taking the Augmentin two days ago. I hope the issues resolve themselves soon and won't require a trip to my gastroenterologist. Augmentin may be fine for some people, but it's definitely NOT for me!"

For Sinusitis "The medicine works, but watch out for the GI side effects. Go to your supermarket in the dairy section and buy the probiotic yogurt drink Yakult. It comes in a pack of 5 1 oz bottles. Drink one bottle each AM and continue for 3 days after stopping Augmentin. You will be free of diarrhea, nausea, and GI side effects. It works!!"

For Sinusitis "I get sinus infections twice a year like clockwork. I usually get a Z-pack and a couple of days of prednisone, and I'm usually better in a couple of days. This time around, I was given 875 mg of Augmentin for 10 days, along with a 10-day step-down dosage of prednisone. I took the meds as prescribed for 4 days and had to stop. I've never had such debilitating stomach pains in my life. I'm talking stomach pains, not intestinal pains. I felt so nauseated, though I never vomited once. My head felt funny, like a headache was trying to develop, and I began to sweat. It has been 5 days since I stopped taking the medications, and I am still having issues with my stomach! Never ever again! I need answers!"

For Urinary Tract Infection "Feeling horrendous, like I'm being poisoned! Was prescribed this after a trip to A&E with an upper UTI/kidney infection. I don't normally take meds, and I'm trying to avoid antibiotics as I have leaky gut, but the Dr urged me to take them as the infection was so bad. Anyway, the first day or two weren't too bad, but then I woke up and felt like I'd been hit by a freight train. Here are some of the things I've been experiencing: nausea, bloating, thrush, severe migraine-like headaches, loss of appetite, depression and mood swings, paranoia, anxiety, dehydration due to constant urination, burning pain in my limbs and a stiff neck, a feeling of being hungover each morning, dizziness and 'brain fog,' and a dry cough! Never taking these again!!!"

For Bacterial Infection "I took my first Augmentin pill at 1 PM after eating a burger and at 5:30 PM. I threw up after having severe nausea and headache. I went to after hours at 6:30 PM, and they gave me medicine Zofran and then a shot for nausea and said not to take any more, that I was having a side effect to it. It did not help, and I threw up three more times when I got home. The last time was 2 AM. I do not recommend this if you have not taken it before. It has been a horrible experience."

For Skin or Soft Tissue Infection "Overall, not too bad. I had some mild nausea and diarrhea the first two or three days, but then I drank Kefir, which helped immensely. Be sure to take it as directed with some food (you don't need a whole meal) and eat yogurt, etc. I highly recommend Kefir during Augmentin therapy. I began clearing the infection by the second day. Remember, most people have little to no side effects with these medications, so what you tend to read on the Internet is negatively biased."

For Bacterial Infection "Prescribed Augmentin fairly frequently for diverticulitis (as I suffer from autoimmune neutropenia too, I am on a lower threshold for treatment as the risk of life-threatening infection is high). I always feel better after two days, but that's when the gates of hell open and the side effects knock me out completely. If I don't take in enough fluids, my kidneys feel like they'll explode, I feel so incredibly weak and lifeless, it gives me a constant headache for the duration of treatment, nausea, no appetite, diarrhea, intestinal pain worse than what it's supposed to treat, and it causes my emotional state to deteriorate severely - I can't stop crying and feel so very stressed, agitated, and anxious."

For Sinusitis "I have horrible allergies and get frequent sinus and ear infections. I have been on Z-pack, Amoxicillin, and Biaxin. Augmentin is the only thing that clears it up. Minimal side effects (some mild nausea) and fast-acting."

For Bacterial Infection "This medication got rid of an infection in a cat scratch, but my God, have I suffered. By day 5, I was constantly on the edge of puking and had loose stool. I toughed it out, took double the probiotics I normally would, and was super excited to be done with it. Unfortunately, 10 days later, I'm still queasy on and off and have random loose stools. I feel like it destroyed my gut, not enough to be concerned about C. diff, just enough to make me feel like garbage and worry about going anywhere."

For Bacterial Infection "I took one dose yesterday afternoon and subsequently had the worst 12 hours of my entire life, bar none. Intense nausea, diarrhea, stomach pain... I'm left feeling very weak and still have pain in my stomach. What a nightmare."

For Bacterial Infection "Took it via IV for five days in the hospital for diverticulitis infection, temperature dropped in a day and inflammation decreased. But had to take two more courses after being discharged to fully clear the infection I found the sickness and nausea very harsh and felt very weak when on it, surprisingly it didn't upset my stomach. Side effects cleared very quickly a few days after stopping it, I would rather take this than the dangerous alternative, Cipro. So would probably take again even though the side effects were difficult."

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 "Was prescribed Augmentin for a sinus infection, and my anxiety has been crazy (already diagnosed with anxiety, and it seems to be worse). My throat felt worse before it got better. I'm also having headaches, nausea, and loose bowels. I can't wait to be done!"

For Sinusitis "Went to urgent care with a toothache. Told I had a severe sinus infection. Mind you, I've had swelling on the left side of my face for 5 years, been through every test out there for answers with no success. Ever since the swelling started, I've suffered ear infections (left side only) and sinus infections to no end. Dentist would tell me my X-rays don't look normal but offered no explanation. Okay, so urgent care prescribed penicillin 500 mg, but I explain to the doctor that I may have a tolerance to that with all the antibiotics I've been on, so she prescribes Augmentin 875 2x a day for 10 days. Over a few days, I'm dizzy, nauseous, pressure headaches like my brain is being squeezed. The worst medicine EVER!!!"

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 "Was prescribed Augmentin 875/125 tab twice daily for 10 days for bacterial sinusitis. I am currently on day 8 now. I was a little iffy about this medication the first two days, as it did upset my stomach and cause many trips to the restroom, even using with food as directed. Day three, I had a nasty headache and insomnia. But honestly, by day 4, I felt pretty good. Actually awoke without any congestion. Energy started returning. Day 5-6, I started having some nausea and congestion again upon waking, but trips to the restroom stopped. Day 8, mild congestion, but feel normal for once. Doc did advise if the post-nasal drip, etc., didn't cease, I may need to see an ENT. So I'd say that this med is doing its job handling the bacterial infection at least. Feel 90% better. Symptoms were uncomfortable when they hit, not unbearable."

For Sinusitis "Was prescribed Augmentin 875/125 for a bad chest infection twice a day for 14 days six months ago, and I barely made it to day 10 and had to quit. I felt horrible, constantly sick to my stomach - gut sick, pain, bloating, gas, and my body felt like the flu, with body aches and strange sweat episodes, and a pounding heartbeat occasionally. Recently, I had a bad case of a sinus infection, so I requested a lower dose of 500 mg when prescribed the same medicine for 7 days, twice a day. I am on day 5 today and absolutely cannot take it anymore; same symptoms. I feel worse, my head is pounding, my stomach is completely full of nausea and gut sick with pain, and I have experienced a small low-grade fever with sweats this time, and brain fog. So that, with all the body aches and burning eyes - I am just gonna let it go again, because I tried. I, however, never had any reactions to Doxycycline or Keflex, but Augmentin is like taking a flu pill for rapid onset."

For Sinusitis "Colds turn into sinus infections pretty easily on me. Yes, I wait a while before I go to the doctor for antibiotics, as most sinus infections are viral. By the time I went to the doc with this one, I was MISERABLE. Hurting down into my jaw even. Within a few hours of taking the first pill, there was relief. I never knew I could have so much disgusting stuff come out of my nose. I always take probiotics (especially while on antibiotics) to decrease GI side effects. TAKE PROBIOTICS. Nausea and diarrhea are possible with any antibiotic."

For Skin and Structure Infection "My neighbor's cat scratched and bit me. At first, I thought I sprained my wrist doing something, but when my wrist was red like a lobster, swelling in pain and pus draining from the bite, I knew it was due to the cat bite. Went to the ER, they said I had cellulitis. They gave me an IV of this, then prescribed it for ten days. Started to work immediately. I had mild diarrhea for the first three days, felt nauseous and very groggy, trouble thinking clearly. I still have dark urine, but my wrist is just about completely healed. I'm on day six, four more days to go. Then I'm done. Regular amoxicillin made me feel weird but didn't give me much side effects, however, I was prescribed amoxicillin for abscessed teeth."
