What are the treatment options for bladder pain?

Treatment Options for Bladder Pain

For bladder pain, begin with behavioral modifications and self-care practices, then escalate to oral medications (amitriptyline, pentosan polysulfate, cimetidine, or hydroxyzine) or intravesical treatments (dimethyl sulfoxide, heparin, or lidocaine) if first-line measures fail, while implementing multimodal pain management throughout. 1

Initial Diagnostic Considerations

Before initiating treatment, exclude reversible causes:

• Obtain urinalysis to rule out infection or microhematuria 1, 2
• Perform cystoscopy if Hunner lesions are suspected, as these require specific treatment (fulguration or triamcinolone injection) and respond well to early intervention 1, 2
• Measure post-void residual in patients with emptying symptoms, neurologic disorders, diabetes, or prior pelvic surgery to exclude urinary retention 1, 2
• Establish baseline pain levels and voiding patterns using validated questionnaires (GUPI, ICSI, or VAS) and voiding diaries to measure treatment response 1

First-Line Treatments (Implement for All Patients)

Behavioral Modifications and Self-Care

These interventions should be discussed and implemented as feasible for every patient with bladder pain: 1

• Fluid management: Reduce daily fluid intake by approximately 25% (roughly 300 mL), which significantly improves urgency, frequency, and nocturia 3. Avoid both excessive restriction and overhydration 1
• Dietary modifications: Eliminate common bladder irritants including coffee, citrus products, alcohol, and caffeine 1
• Use an elimination diet to identify individual food triggers 1
• Apply local heat or cold over the bladder or perineum for symptomatic relief 1
• Implement stress management practices including meditation and imagery to manage flare-ups and stress-induced exacerbations 1
• Practice pelvic floor muscle relaxation and bladder training with urge suppression techniques 1
• Consider over-the-counter products such as quercetin, calcium glycerophosphates, or phenazopyridine 1

Multimodal Pain Management

Initiate pain management approaches early, combining pharmacological and non-pharmacological strategies: 1

• Pain management alone is insufficient; it must be combined with treatment of underlying bladder symptoms 1
• Use non-opioid alternatives preferentially due to the opioid crisis; reserve chronic opioids only after informed shared decision-making 1
• Consider referral to pain specialists for intractable pain or complex presentations 1

Second-Line Oral Medications

If first-line treatments are ineffective, offer one of these oral medications (no hierarchy implied): 1

Amitriptyline (Grade B Evidence)

• Superior to placebo for IC/BPS symptom improvement 1
• Start at 10 mg and titrate gradually to 75-100 mg if tolerated 1
• Common adverse effects include sedation, drowsiness, and nausea, though not life-threatening 1

Pentosan Polysulfate (Grade B Evidence)

• The only FDA-approved oral agent for IC/BPS 1, 4
• Indicated for relief of bladder pain or discomfort associated with interstitial cystitis 4
• Dosing: 100 mg three times daily 4
• In clinical trials, 38% of patients showed >50% improvement in bladder pain at 3 months versus 18% with placebo 4
• Counsel patients on potential risk for macular damage and vision-related injuries before initiating or continuing treatment 1

Cimetidine (Grade B Evidence)

• Clinically significant improvement in IC/BPS symptoms, pain, and nocturia with no reported adverse effects 1

Hydroxyzine (Grade C Evidence)

• Results in clinically significant improvement compared to placebo 1
• Patients with systemic allergies may be more likely to respond 1
• Common adverse effects include short-term sedation and weakness 1

Second-Line Intravesical Treatments

May be administered if oral medications are ineffective or not tolerated (no hierarchy implied): 1

• Dimethyl sulfoxide (Grade B/C evidence) 1
• Heparin (Grade B/C evidence) 1
• Lidocaine (Grade B/C evidence) 1

These treatments are associated with minor adverse events, and efficacy is unpredictable for any individual patient 1

Third-Line and Advanced Therapies

For patients who fail second-line treatments: 1, 2

• Botulinum toxin injection into the bladder for severe refractory cases 2
• Sacral neuromodulation if intravesical treatments fail 2
• Pelvic floor muscle training and biofeedback as part of comprehensive management 2

Critical Management Principles

Reassess treatment efficacy periodically and stop ineffective treatments: 1

• No single treatment is effective for the majority of patients 1
• Acceptable symptom control may require trials of multiple therapeutic options, including combination therapy 1
• If no improvement occurs within a clinically meaningful timeframe, reconsider the diagnosis 1
• IC/BPS is typically chronic with symptom exacerbations and remissions; continual and dynamic management is required 1

Common Pitfalls to Avoid

• Do not perform routine cystoscopy on every patient; reserve it for those with suspected Hunner lesions or unclear diagnosis 1
• Do not delay treatment waiting for prolonged symptom duration; the definition allows treatment after 6 weeks 1
• Do not use pain management as sole treatment; always address underlying bladder symptoms 1
• Avoid excessive fluid restriction that could lead to dehydration or concentrated urine, which may worsen symptoms 1
