For Bladder Infection "Horribly painful on your stomach! I took 1 dose of this Wednesday morning for a bladder infection/UTI. Within a couple of hours of taking it, I would've been cleared to have a colonoscopy. Since then, I've had stomach cramps so bad it feels like a sharp pain that lasts about 2 to 3 minutes at a time. I'm 36, paralyzed from the waist down with decreased sensation as of 2 years ago. I can't imagine how these cramps would feel with full sensation. I get complicated UTIs that Macrobid, Bactrim, Cipro, and Cefdinir won't treat, which is why I was prescribed fosfomycin. I'll never, ever take this again. Seriously, if you get prescribed this medication, ask your doctor what else is available that you could try first. I wouldn't wish this stomach pain on anyone."

Fosfomycin for Bladder Infection "Do not take this drug! Took it while in Singapore, single dose, as I thought it would be easier than a 5-day course. I have been so ill with diarrhea after every meal, nausea, and stomach cramps. This is my 5th day and still not well. I have no appetite and exhausted."

For Bladder Infection "I was told that fosfomycin is as effective as Macrobid, is a one-time use medication, and is a powder that dissolves into 1.5 cups of water. However, my urine would need to be tested to see if I have any culture that could prevent the antibiotic from working. This medication works after 72 hours and is ingested on an empty stomach. If you are prescribed this medication, you're honestly better off receiving an antibiotic that is stronger and not a one-time use prescription. Today, I went into another walk-in clinic, explained the situation, and the doctor said that fosfomycin is not a strong medication. Again, try it for yourself with the chance of this antibiotic not working. The side effect symptoms I had were stomach cramps and diarrhea. It did subside other symptoms: after one day I didn't feel sick, and by day two, I had no burning sensation. However, by this weekend, my left side became sore (which is where your kidneys are), and that was enough for me to go see the doctor."

For Bladder Infection "Horrible experience. Within hours of taking it, I had severe indigestion, trouble breathing, a bloated stomach, chest pain, diarrhea, and my heart rate has been between 90-120 all day, and I could feel it pounding all day. Medicine hasn’t seemed to be efficient either. Would not recommend, the side effects are scary."

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 "Took this for a mild bladder infection and initially felt improved. But then stomach cramps, abdominal discomfort to the point of serious pain, nausea-literally kept getting new symptoms and feeling worse and worse. And I’ve still got the bladder symptoms. Would never recommend this."
