For Urinary Tract Infection "I understand the good outweighs the bad, however, the past few days have been hell. I had honestly one of the worst urinary tract infections I have ever had. I need the relief, so I am going to continue with the meds. Within 24 hours of taking it, I had horrible diarrhea. I am pale, I keep drinking water."

For Prevention of Bladder infection "I was prescribed a low dose of it for prevention of UTIs, and it gave me diarrhea, which, for someone already dealing with IBS and constant UTIs, is not helpful at all. Aside from that, no side effects. Still stopped taking it, though, and was prescribed methenamine. Hope it works!"

For Urinary Tract Infection "I am 45, and I am currently taking Macrodantin to treat a UTI. Never have I ever felt so bad taking medication. I initially thought my body was fighting the infection, but it wasn’t the case. I am now taking the medicine (4x100mg/day). I feel very tired, very dizzy, I have diarrhea. My breathing is not great, and I feel a bit confused... definitely not myself. Also, pains in my fingers... I can't wait to finish the treatment tomorrow. On a positive side, the infection seems gone as urine is clear."

For Urinary Tract Infection "No one should be taking this drug. I was prescribed this for a kidney infection when I have chronic kidney disease on 4/22/21. I will be alerting the doctor who prescribed this that they nearly killed me. Was prescribed a dosage of 100 mg 4 times a day for 7 days. Took it till 4/27/21. Made me feel like I was dying with extreme chills and fever, excruciating back pain, whole body aching, diarrhea, abdominal aching, gave me asthma and filled my chest with fluid, was very weepy, extreme anxiety, difficulty walking - felt like walking through cement, dizziness, retained fluid, and dropped my kidney function significantly. Was too sick to realize it was the tablets until the last day, stopped them, and went to another doctor on 4/28/21, who wanted me to go to the hospital to go on IV, etc. Stopped taking the tablets, started a different antibiotic yesterday, 4/28/21, and have started to feel better already."

For Urinary Tract Infection "This year I have struggled with repeat UTIs. I have taken Macrodantin each time. The first two times for 3 days, and it cleared up. The third time for 7 days, it cleared up. This time I took it 100 mg for 5 days. After the 3rd day of being off the drug, the UTI returned. Now I'm on another 5-day course. I do experience insomnia and distorted dreams. With the first course, I had severe diarrhea. No diarrhea with the second course. Can't wait to be rid of this drug and infection."

For Prevention of Bladder infection "I take it every night to prevent recurring UTIs, but it gives me gas and diarrhea that is embarrassing when out in public."
