Which treatment is not typically used for interstitial cystitis?

• A. Beta-3 agonists
• B. Bladder dilation
• C. Broad-spectrum antibiotics
• D. Anticholinergic medications

Answer: (C)

The key idea here is that interstitial cystitis is not driven by a bacterial infection, so treatments focus on reducing bladder pain, inflammation, and overactivity rather than killing bacteria. Broad-spectrum antibiotics target bacteria, which is why they’re not a typical or effective long‑term treatment for interstitial cystitis itself. They might be used only if there is a concurrent infection or if infections were part of another diagnostic consideration, but they don’t address the underlying bladder irritation central to interstitial cystitis.

In contrast, options like beta-3 agonists help relax the bladder and reduce urgency, bladder dilation (hydrodistension) can temporarily increase bladder capacity and ease symptoms, and anticholinergic medications help decrease bladder spasms and urgency. These approaches align with managing chronic bladder pain and storage symptoms rather than treating an infection, which is why they are considered for interstitial cystitis.
