Amoxicillin / clavulanate for Middle Ear Infections "This medication has always worked great for me whenever I have an ear infection... much better than the regular Amoxicillin too. However, be sure to follow your doctor's orders by taking this medicine with food while getting enough probiotics, as it will give you stomach problems along with diarrhea if you don't comply."

For Strep Throat "I was given this by urgent care to treat my strep throat. The first day of taking this, I was perfectly fine... Day 2, I started having severe diarrhea. I mean, it is coming out all day long like a faucet, just so much diarrhea. I literally cannot stop pooping. It's day 3, and I think I am going to have to call the doctor back... the infection is leaving already, which is amazing, and it is an amazing drug other than the awful diarrhea. I am eating yogurt too."

Amoxicillin / clavulanate for Skin or Soft Tissue Infection "I've been taking this for about two weeks to combat cellulitis, and after first trying Keflex and Bactrim, which did not work, the Augmentin is working quite well. I haven't had any stomach upset or GI discomfort. I haven't had any diarrhea that couldn't be easily stopped with a normal dose of over-the-counter loperamide. Had a slight bit, but the loperamide fixed that right up."

Amoxicillin / clavulanate for Upper Respiratory Tract Infection "I am now on day 7 taking Augmentin for an upper respiratory and sinus infection. Was so ill I could not wait to start taking it. I feel a lot better but still not there yet. Still have a dry cough at night and sinus problems. On the 2nd day of taking it, I developed diarrhea, very dark and loose. Still have it but not as severe. These are just inconveniences compared to how sick I was. Glad I'm taking it."

Amoxicillin / clavulanate for Sinusitis "I was given this by an ER doctor for sinusitis. I took the first dose at the ER then didn't get a chance to fill the prescription for a week. Was still feeling a little bit of ear congestion from sinusitis, so I grabbed it. The first pharmacy dose gave me nonstop diarrhea and severe nausea, like my stomach was going to explode. So now, I drink probiotic yogurt with a full meal. Took it 2 more times, not as bad but constant anxiety. Had to stop, as I felt worse when taking it. Head congestion is pretty much gone, though I just decided to take Mucinex, and I feel like that has helped even though I'm still dealing with it a bit. Never taking it again."

Amoxicillin / clavulanate for Strep Throat "This medication did clear up my strep throat within the first couple of days being on it. However, the side effects were horrible. I had watery diarrhea for like 3 days, I always felt nausea after taking it even with food, and I had strong stomach pains. Also, by the 4th day on it, I had a yeast infection."

For Upper Respiratory Tract Infection "Some of these reviews had me worried because I hate side effects, but the throat was so painful I had to try it. Glad I did, I'm now on day 9 of two times daily, and the infection is gone, no pain. No side effects at all. No nausea, no diarrhea, no headaches. Worked well."

Amoxicillin / clavulanate for Skin or Soft Tissue Infection "I was prescribed Augmentin for what my doctor thought was a skin infection on my right leg. Well, after taking my first dose, within 2 hours, my stomach became extremely upset... burning... nausea... diarrhea... bloating... and anxiety and panic have always been an issue for me, but after Augmentin, it was immediately 20 times worse. My doctor ended up telling me to stop taking it on day 5 because it was getting worse and worse. My skin infection cleared up with some hydrocortisone cream and antibiotic ointment, but it's been over 3 months since stopping this medication, and I'm still having major stomach issues and mental issues, so please be careful, people, especially if you have anxiety or stomach issues beforehand."

Amoxicillin / clavulanate for Bronchitis "I am on day 2 of antibiotics. I took the Z pack only one dose and had a horrible reaction to it. (Swelling of face, fever, diarrhea, you name it.) Stopped taking it, and two days later, started Augmentin. I have been taking Culturelle (Lactobacillus GG) two hours before or after taking the antibiotics. Seems to be helping. No diarrhea. No gas. No hives/itchy skin. But I don't know if it's long enough to tell. ***Take those probiotics.*** Dairy products are putting me over the edge. Stick to non-dairy while taking this."

Amoxicillin / clavulanate for Urinary Tract Infection "This is a strong antibiotic, and it’s horrible on the stomach. After only a couple of hours, my entire stomach was hurting very badly, with severe diarrhea and anxiety. I switched to Keflex, hoping it’s better."

Amoxicillin / clavulanate for Sinusitis "I took this for 4 days, and now I’m seriously regretting it. I have serious diarrhea and the worst stomach pain and cramping imaginable. The severe diarrhea has meant 10-15 bowel movements per day. They have been pure liquid. I’m now on day 3 of the episodes, and the diarrhea is now about a 1 to 1 mix of blood and stool. My appetite is shot, and because of the pain and diarrhea, I’m afraid of eating. The stomach pain is so severe that I’ve been bedridden for the last 3 days. It’s so bothersome I’m not able to work from home while I’m off work. It’s kept me awake every night where I get 2-3 hours of sleep, and then the pain builds back up, which requires a pill for pain that I supplement with Tylenol. I’m waiting to hear back on the lab results from the stool sample I provided. There is a chance that my stomach chemistry is damaged to the point that I may have contracted an illness called C. diff, which will require a 3rd type of antibiotic."

Amoxicillin / clavulanate for Sinusitis "I am at the end of day 3 of the medication, and I can't do it anymore. The side effects are making life miserable, just in a different way than I started with. I went in because of the headache and congestion that would not respond to anything over the counter, plus vertigo. The vertigo went away after the first day of meds, but the headache is significantly worse. Additionally, my stomach hurts really bad and constantly feels like I have overeaten a massive amount all the time, whether I have eaten or not. I have also had some mild diarrhea. So not worth it for me!"

Amoxicillin / clavulanate for Sinusitis "Was put on this for an ear and sinus infection. By my second day, I was having bad stomach cramps, excessive bowel movements, some diarrhea, nausea, body aches, joint pain, fatigue, brain fog, nerve tingling in legs and feet, constant headache. Also, I began spotting on my second day, and it was one week before my period was due, this never happens. I spotted until my period started. I have three more days left, and I feel worse than I did before I started it. My ear isn’t completely better yet either, my sinuses have cleared up some but not all the way. I called my doctor, and he said he is hesitant to change my script as my infection was/is so bad, and asked that I just push through side effects. Never again!"

For Bacterial Infection "Within an hour of taking one pill, I was in so much pain. My stomach had me balled up into the fetal position, then severe diarrhea and vomiting began! If one pill can cause so much havoc, I'd hate to see what a second one will do (I will never use this med again). This was hands down one of the worst and most painful nights of my life! My present state is laying on the bathroom floor."

Amoxicillin / clavulanate for Bacterial Infection "Taking this for an unknown bacterial infection - confirmed with CBC, but I personally suspect it's early onset of appendicitis. I'm on a pretty high dose according to my doc (500 mg 3x daily), and oh man. The brain fog is maybe the worst symptom. It starts in about an hour after taking it and settles in for a few hours. It just feels hard to focus on anything, like my vision is blurred almost. Between that and the insomnia, nausea if I eat food anytime between doses, and diarrhea, what a fun medication!! Loss of appetite too I've noticed. I think it's increased my anxiety too, but I'm a bit of a hypochondriac to begin with, so I don't know, my anxiety might be increased just because this drug is whacky. I'm on this thing for 10 days. Today is day 3. Noticed an improvement in my infection symptoms I think? Much less abdominal pain, but it's hard to get a good gauge on that when you're having diarrhea so much!!"

For Bacterial Infection "Was on amoxicillin/clavulanate after getting my wisdom teeth out as a preventative measure. I had to stop after 4 days because I got pretty severe diarrhea. That was a pretty big mistake (and why you should ALWAYS finish your antibiotics, no matter what!) because I got an infection. So I had to go on it AGAIN, and for longer than I would have had to take it previously (7 vs. 14 days). This time, in order to prevent diarrhea, I took probiotics religiously to replace my decimated gut flora. Thankfully, that was enough to stave it off for the duration of treatment. All in all, I would definitely recommend going on a probiotic while using this medication, as it helped me immensely."

Amoxicillin / clavulanate for Middle Ear Infections "I took 875 mg 2 x per day. It cleared up my ear infection, however, I had diarrhea for most of the 4 days I was taking it. It was a constant diarrhea too, and a few times it just happened, I wasn’t able to control it. I took it with a probiotic each day. I felt nauseous each day and each time I took it. I also felt very out of sorts mentally and felt like I struggled with doing my job and felt anxiety. The day I didn’t take it during work, I felt much better and back to normal. I dropped it after five days and do not intend to take it again. This was a terrible experience."

Amoxicillin / clavulanate for Upper Respiratory Tract Infection "Within 20 hrs (2 doses), I was feeling better. My lungs still hurt when I would cough, but they didn't hurt when I would take a shallow breath. I did get a pretty bad headache that was controlled with APAP. Loose stools developed after day 3. I increased fluids and fiber (ice cold smoothie worked great to fulfill these). Day 6, I was back to normal except for the loose stool. No other complaints. I was also on pearls and codeine during this time. Side effects well worth the benefit after how bad I was hurting."

For Bacterial Infection "Currently taking this for bronchitis/early pneumonia. Had diarrhea, but it got better after a day or two. The med is definitely doing its job in killing all the garbage in my body associated with the infection. Normally I have great energy, this is my 7th day of the med, and I feel as though I am exhausted constantly, feel like I’m wrapped in a warm, soaked, heavy blanket that I’m dragging around with me. It’s a side effect, I’ll continue to tough it out. It’s better than when I was sick and coughing constantly, lungs and chest so sore and red I was miserable. It’s killing bad bacteria in your body, your body is then getting rid of it with sweat and normal bathroom functions, so to be a bit off or frequency increase to me is a good thing. The tiredness thing gets to you, but don’t just go off the med and have the bacteria come back in some super form. Call your doc, try and tough it out, don’t just stop taking."

Amoxicillin / clavulanate for Skin or Soft Tissue Infection "I was prescribed Augmentin (Amox-Clav) 125 mg every twelve hours for 10 days. Starting having diarrhea the day I started, and by day five, I became so sick I thought I was going to have to go to the ER. Horrible stomach pain and cramps, fever, extreme weakness, painful muscles, mainly in legs, nasty sweat, nightmares, and I lost my sense of smell...which may have been a good thing since I was pretty much stuck in the bathroom. The fever and pain lasted two days after I stopped taking the Augmentin on day five. The diarrhea has continued (on day eight after discontinuing drug) and is pretty much spontaneous. I can’t go anywhere. I have never had stomach issues in my life (I’m 50). I fear my gut is damaged beyond repair. This is a nasty, nasty drug. Also, has worsened my depression and mental state in general."

Amoxicillin / clavulanate for Urinary Tract Infection "I was given Augmentin to take after I got an ear infection in the left ear but also had a perforated eardrum on the right. I went to the doctor's after a week, and not only had the infection started to heal, I now had an infection in both ears. He prescribed me more and seemed stumped as to why I was not improving. It's now been 2 weeks, and I have suffered diarrhea and have been dealing with thrush for the past 3 days. On top of this, I am constantly in a massive state of confusion, and my skin is dry and red, my pills have ceased to work. I have stopped taking them and am seeing the doctor tomorrow. Not only did the antibiotics not help my original problem, now I have a whole list of other issues I need to fix."

Amoxicillin / clavulanate for Sinusitis "Prescribed a 10-day round for sinus infection in February 2016. Immediately developed digestive issues, cramping, loose bowel movements, gas, and bloating. It is now 6 months later, and I am still battling the issues. Doctors first thought it was UC, but after a colonoscopy, now think IBD or IBS, maybe Celiac. I'm headed to the hospital for additional testing."

For Middle Ear Infections "Was prescribed this medicine for 10 days, had to finish on the 7th day. Absolutely terrible side effects. Chest pain, shortness of breath, diarrhea, constipation, muscle aches, muscle spasms, eye twitching. I took the medicine with food and still had awful acid reflux. Five days without the medication, and I am still having chest pain, diarrhea, muscle aches, ear ringing, anxiety, etc. I hope all of this goes away soon so I can get back to normal. It did clear the ear infection, but I would never take this again."

Amoxicillin / clavulanate for Sinusitis "Went to the ER two times with what later I learned was a severe sinus infection. My Dr. gave me Augmentin, and although much better after a week, it isn’t gone. I took it with yogurt and probiotics because the first couple of days I had cramping and diarrhea. That helped tremendously."
