Use of Prophylactic Antibiotics Prior to OnabotulinumtoxinA

This study aims to show that lack of antibiotic prophylaxis to those undergoing bladder Botox injections is not significantly inferior to administering prophylaxis. By proving this, the investigators aim to decrease antibiotic use in this setting to combat the growing issue of antibiotic resistance. Participants will be randomized to antibiotic or no treatment arm. Those randomized to the treatment arm will receive oral antibiotics for 2 days pre-treatment, on the treatment day, and 2 days post-treatment. Participants will return for a follow up appointment approximately 2 weeks after treatment to assess for urinary tract infection (UTI) symptoms. They will be called again at 6 weeks for follow up.
