For Urinary Tract Infection "Worse experience I've ever had. I'm pregnant, so I thought maybe it was the pregnancy causing all these bad symptoms, but no, it was a UTI. Abdominal pains, throwing up, diarrhea. I didn't even want to move. Took my last dose today, and I couldn't wait. Yes, it cured my UTI, but the side effects were the worst."

For Urinary Tract Infection "Never again. Day one, I felt drowsiness, as suspected. Day two, nausea! I thought it was something I ate. I’m on day three now, and I felt nausea again, shortness of breath this time, and also mild diarrhea. I’m done taking this, and I’m going to call my doctor tomorrow. My UTI doesn’t feel like it’s there anymore, though. I will still never take this again. I’ve never had any side effects like this with other UTI meds. This is ridiculous."

For Urinary Tract Infection "This is just my 3rd day on this medication, and I am not sure what to do. I vomit about 2-3 hours after a dosage, loose stool, horrible smelling gas, upset stomach, and neon green urine. However, my UTI appears to be going away. I never want to experience this again."

For Urinary Tract Infection "Went to the doctor for an annual checkup and apparently had a mild UTI. I’ve finished 4 days of Macrobid but am unsure whether I can tough it out on Day 5. I’ve had headaches, muscle pain, nausea, severe diarrhea, severe stomach pain, and insomnia. Not to mention I started an antidepressant on day 1 of this, and I’m PMSing, which also worsens these symptoms. I was stuck in a car for 6 hours today and 4 hours tomorrow... this medication is not compatible with driving."

For Bladder Infection "I had a horrible experience with this medication! I had a UTI and took my 5 days (twice a day every 12 hours) like I was supposed to and felt fine while I was taking it. 48 hours after my last pill, I was in the ER with bleeding, stomach cramps, chills, fever, diarrhea. I was diagnosed with colitis! Never ever experienced this in my 53 years of life with antibiotics. I'm on a new antibiotic now to clear up the infection in my colon and have to make an appointment with a stomach doctor. It was one scary experience taking an antibiotic that you thought was safe! Never again."

For Urinary Tract Infection "I was prescribed 100 mg of this medication, Macrobid, for UTI, and each time I take it, I feel worse off. I am either experiencing a fever or chills, and I am extremely nauseous for hours on end with a loss of appetite. I am also having symptoms of indigestion and constant diarrhea. This is an awful medication, and in the wrong hands, practitioners may be prescribing this to the wrong type of patient. I have 1 more day left to take this, and I don't think I can. It debilitates me."

For Urinary Tract Infection "DO NOT TAKE THIS!!! DO NOT TAKE THIS!!! After the second pill - I had diarrhea that would not stop and eventually turned into burning, watery stool. Severe stomach cramps, fever, chills, nausea, dizziness. I stopped taking Macrobid after 3 pills, but my diarrhea did not stop. I could not eat or drink anything without going to the toilet. I fainted for the first time ever while trying to get back to my bed. I went to the ER for dehydration, and the doctor prescribed Zofran. Macrobid is now on my allergy list."

For Urinary Tract Infection "I was a little fatigued and had some loose bowel movements, but I no longer cry when I pee, so I'd call that a win!"
