Brief Summary
The goal of this clinical trial is to learn more about using phenazopyridine (Pyridium) for pain control during bladder onabotulinumtoxinA ("botox") injections for surgical management of overactive bladder (OAB) for patients at Montefiore Medical Center in The Bronx. It will also learn about if using the phenazopyridine pill affects how satisfied patients are with their experience, how much pain patients feel afterwards, and if doctors think using the Pyridium pill affected how they performed the procedure. The main question it aims to answer is: \- Is oral phenazopyridine at least as good as intravesical lidocaine is for managing pain with bladder botox injections for OAB in Montefiore patients? Researchers will compare phenazopyridine to intravesical lidocaine, a liquid put into the bladder, to see if phenazopyridine is at least as good at controlling pain with bladder botox injections as intravesical lidocaine is. Participants will be assigned, by chance, to receive either the oral phenazopyridine pill or the intravesical lidocaine as their pain control for the procedure.

Outcome Measures
Primary Outcomes (1)
Bladder Pain
Patient-reported bladder pain will be assessed using the Visual Analog Quality of Life Scale (VAS) tool. The VAS is a unidimensional measure of pain intensity. The 100mm VAS intervention tool consists of an emoji face scale ranging from an "open-mouth smile" emoji to a crying emoji. Patients will place an 'x' on the number line below the emojis to indicate where on the scale they would rate their pain, using the emoji faces as a guide. The distance from the lowest (farthest left) point on this scale to the 'x' will be measured and reported in millimeters. Higher scores are associated with increased levels of bladder pain intensity. Group median pain scores will be tabulated and reported.

Study Arms (2)
Oral phenazopyridine
ACTIVE COMPARATORPatients randomized to the oral phenzopyridine arm will receive 200 milligrams (mg) phenazopyridine orally prior to the scheduled procedure.
Intravesical lidocaine
ACTIVE COMPARATORPatients randomized to the intravesical lidocaine arm will be administered 50 cubic centimeters (cc) of 1% lidocaine with 50cc sodium bicarbonate within the bladder immediately prior to the procedure.
Interventions
200mg PO Phenazopyridine taken prior to the Botox® injection procedure as an analgesic.
50cc of 1% lidocaine with 50cc sodium bicarbonate injected into the bladder lumen prior to the Botox® injection procedure.
