Interstitial Cystitis: Why Antibiotics Fail & What Actually Works

Interstitial cystitis/bladder pain syndrome (IC/BPS) is a non-infectious chronic bladder condition: pelvic pain, urgency, frequency, nocturia. Antibiotics don't work—no bacteria to kill—and can worsen symptoms by disrupting microbiome.

Evidence-Based Treatments

• Oral meds: Amitriptyline, cimetidine, pentosan polysulfate (Elmiron®), antihistamines.
• Bladder instillations: DMSO, heparin, lidocaine, bicarbonate cocktails.
• Pelvic floor PT: Critical—most IC patients have pelvic floor dysfunction.
• Diet modification: Avoid triggers (caffeine, alcohol, citrus, tomato, spicy, artificial sweeteners).
• Stress management: CBT, mindfulness, biofeedback.
• Neuromodulation: Sacral nerve stimulation (InterStim), PTNS.

Diagnosis First

Rule out UTI, stones, cancer, endometriosis. Cystoscopy with hydrodistension may show glomerulations/Hunner's lesions. See a urologist or urogynecologist specializing in IC.
