Dupixent isn't currently listed among the recognized treatments for PBC-related itching, so it's hard to speak to that specifically. The itch that comes with PBC is driven by bile acid buildup rather than the immune pathway Dupixent targets, which may be why it hasn't been studied for this use.
Here's a quick rundown of what is currently used or being explored for PBC-related itching:
- Cholestyramine – the first-line, FDA-approved option that binds bile acids in the gut
- Rifampin – a second-line option that helps reduce itch signals to the brain
- Opioid antagonists (like naltrexone) – block receptors involved in the itch response
- SSRIs (like sertraline) – small studies show some benefit
- Fibrates – can be taken alongside UDCA with promising results for itch
- IBAT inhibitors (like linerixibat and volixibat) – newer drugs in development that look very promising If current treatments aren't cutting it, it's absolutely worth having an honest conversation with your doctor. You might also ask whether you qualify for a clinical trial, which could give you access to newer therapies before they're widely available.
