For Interstitial Cystitis "This medication has helped me greatly in coping with interstitial cystitis (IC). There are different types of pain associated with IC, and this medication helps with one of the most debilitating, which is a hot poker feeling that starts in the urethra and continues straight up the center. Also, some of the urgency to urinate is relieved. Even with this medication, I am attached to a heating pad, but without it, there is nothing left of me other than the pain. As for side effects, I have to eat first or I become nauseous with occasional vomiting and headaches. Well worth it."

For Dysuria "Took the medicine last night for the first time. Didn't notice any changes, except that it made me sleepy. This morning I awoke to find that I had a major headache, terrible stomach cramps, all-over body ache, and confusion. I would not recommend this product, as it also gave me really weird dreams."

For Dysuria "My husband went to the ER a few days ago due to painful urination and bleeding. No sign of infection yet nor of stones, but traces of blood in the urine. They gave him Uristat to help with the pain. He says it is helping some with the pain, but the side effects are not good. He is having awful nausea and headaches and can barely stay awake after taking it. Been going to bed at 7 pm. Just very miserable. Thankfully, it was only to be taken for three days. Hoping his symptoms ease tomorrow. I don't think he will jump at the chance to take this drug again."

For Dysuria "I was given this medication after a procedure for kidney stones. It was given to me in recovery with no way to research it. It is in a family of drugs I am allergic to. It caused severe abdominal pain, dizziness, confusion, headaches, and vomiting. It contains Red 40, which is being studied for toxicity. Also, as of Sept 2022, this drug is not FDA-approved. Research this drug before taking it! It made me extremely ill."

For Interstitial Cystitis "Gave me terrible lower back pain, headaches, and only provided some relief with pain while urinating but no relief for having to pee constantly. Would not recommend."
