For Urinary Tract Infection "My doctor prescribed this for a potential UTI (frequent urination and trace of blood in pee). Seemed easy, one packet and done, so I thought. Took it late in the day on Tuesday, and by Wednesday I started to have pain in my stomach and then nausea and diarrhea. By Thursday into Friday, it was more frequent, and then began the rash on my skin-very intense itchy spots and then welts. By Friday night, I started to have excruciating lower back pain, and then Saturday it was all the above and added in groin pain. I feel awful. Going to the doctor tomorrow. I feel so horrible and still have urgency."

Fosfomycin for Bladder Infection "My UTI seemed to improve slightly the first 24 hours after taking Monurol, but after 48 hours, I had developed back pain along with a high fever. Returned to the clinic and was put on Cipro, which was much more effective."

For Bladder Infection "Used orally for UTI, and all the side effects just started to appear day by day, and instead of becoming healthy, I deteriorated. Diarrhea, abdominal and back pain, nausea, chest pain, dysuria, sleeplessness just started to aggregate, and now I am in the most miserable condition. Won't recommend at all."

Fosfomycin for Bladder Infection "Horrible, this Monurol. My 4th day of taking it, and I feel ill. My stomach is burning, pains in my kidneys, back pain. I can’t stop feeling sick, I have to go back to have my urine checked. Also, my throat feels blocked. Can’t understand why they would give anyone with water infections this horrible drug. Will never touch it again."

For Bladder Infection "I was so excited to get a one-dose instead of a 7-day antibiotic. I took it on Friday around 11:30 a.m., and within an hour, I had these terrible stomach pains that lasted around 6 hours. Then they were on and off and went away by the time I went to bed. Then I woke up in the middle of the night with back pain, on the right side just above my butt. This dull, aching feeling I’ve never had before. Still dealing with it on Sunday. Also had some diarrhea that lasted all Saturday. I’ve felt miserable on this. Hoping this UTI hasn’t moved to the kidneys now. Burning urine and UTI pain seem to have passed, but with the side effects… this is NOT worth it."

For Bladder Infection "I was skeptical of this med after reading reviews, but how bad could it be? Plus, I thought one dose is way better than trying to remember more. Buckle up, it's that bad. I'm on day three after taking it for UTI. Within 30 minutes of taking it, I started to feel pressure in my abdomen. Shortly after that, I felt like an overinflated balloon. The bloating wouldn't stop. I had been advised to drink lots of water, which I did, and I went from feeling like I had to go all the time to not being able to at all, which did eventually subside. Make a note, when they say drink lots of water, they don't mean just the day you take it. They mean every day for a few days. I woke later that night with diarrhea, and it has not stopped since. I also have had a migraine and now have pain in my lower back. I still have some UTI symptoms."
