Dysuria
"I took one of the 200mg pills as prescribed to me for UTI symptoms. I took it with a meal and a glass of water as suggested. It did work relatively quickly to get rid of the urgency, burning, and pain. Unfortunately it caused me to vomit up everything I ate and drank within 5 hours of taking it. Severe dizziness, nausea, and uncontrollable vomiting are not worth the benefits of the medication."
