Antibiotics after bladder botox may cut infection risk
NCT ID NCT04791579
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether taking a short course of antibiotics (ciprofloxacin) after Botox injections into the bladder can reduce the chance of urinary tract infections. About 160 adults with neurogenic overactive bladder (due to conditions like multiple sclerosis or spinal cord injury) will be randomly assigned to receive either antibiotics or a placebo. The goal is to see if this simple step can make a common procedure safer.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Ciprofloxacin (antibiotic)
- What this could lead to
- If it works, this could provide a simple way to prevent bladder infections after Botox injections, improving safety and reducing antibiotic overuse.
- What could go wrong
- This is a small Phase 2 trial, so results may not apply to everyone. Ciprofloxacin can cause side effects like nausea, and overuse may contribute to antibiotic resistance.

Inclusion Criteria: 1. Participants with neurogenic OAB, defined as OAB associated with a neurologic condition such as multiple sclerosis, Parkinson's disease, spinal cord injury, previous stroke, or any other neurologic condition the participant may have been told is a cause of their OAB symptoms 2. Age ≥ 18 3. Participants must be able to read, speak, and write in English 4. No contraindication to injection of Botox - hypersensitivity to any botulinum toxin preparation or to any of the components in the formulation, symptomatic urinary retention or PVR \> 200 mL, unwillingness or inability to initiate CIC post-treatment if required. 5. No contraindication to oral Ciprofloxacin - hypersensitivity or allergy to Ciprofloxacin or other fluoroquinolone, concurrently taking Tizanidine or Agomelatine. 6. No active antibiotic therapy for any indication at the time of Botox injection 7. Not pregnant and/or breastfeeding - Botox is contraindicated in pregnancy (screen serum pregnancy test 72 hrs prior to the procedure is standard of care). 8. No active symptomatic UTI the day of the procedure - wherein the participant presents the day of their Botox procedure with new or worsening urinary frequency, urgency, dysuria, hematuria, suprapubic/flank pain, fevers or chills, will be ground for exclusion from the study - bladder Botox is contraindicated in patients with active symptomatic UTI Exclusion Criteria: 1. Participants with idiopathic OAB 2. Age \< 18 3. Patients who cannot read, speak, and write in English 4. Any contraindication to injection of Botox - hypersensitivity to any botulinum toxin preparation or to any of the components in the formulation, symptomatic urinary retention or PVR \> 200 mL, unwillingness or inability to initiate CIC post-treatment if required. 5. Any contraindication to oral Ciprofloxacin - hypersensitivity or allergy to Ciprofloxacin or other fluoroquinolone, concurrently taking Tizanidine or Agomelatine. 6. Active antibiotic therapy for any indication at the time of Botox injection 7. Pregnant (as indicated by pre-operative serum quantitative B-hCG for patients aged 18 to 51 without previous hysterectomy) and/or breastfeeding 8. Active symptomatic UTI the day of the procedure - wherein the participant presents with new or worsening frequency, urgency, dysuria, hematuria, suprapubic/flank pain, fevers or chills, will be ground for exclusion from the study.
