Short answer: Yes, cautiously, but treat it as a sleep aid, not an anti-itch drug — and clonazepam is not the best benzodiazepine choice in this patient.

Why clonazepam alone doesn't solve the problem

The itch in metastatic cholangiocarcinoma is typically cholestatic pruritus from biliary obstruction (bile acid/bile salt and other pruritogen accumulation), not histamine-mediated. Textbook sources (Sabiston, Schwartz's, Robbins & Cotran) confirm pruritus is a classic feature of biliary obstruction from cholangiocarcinoma - Sabiston Textbook of Surgery, p. 946-953; Schwartz's Principles of Surgery, p. 3713-3721. Clonazepam has no direct anti-pruritic mechanism; it only sedates, which can secondarily improve sleep despite ongoing itch. Used this way (short-term, at bedtime) it's a reasonable adjunct, but it doesn't address the itch itself, so the patient will likely keep scratching/waking once sedation wears off unless the underlying pruritus is also treated.

Hepatic-impairment caution — clonazepam isn't the preferred benzodiazepine here

Per the Maudsley Prescribing Guidelines in Psychiatry (15th ed), benzodiazepines with active metabolites — diazepam, midazolam, and clonazepam — undergo extensive hepatic metabolism and have prolonged duration of effect in liver impairment. The preferred agents in patients with hepatic dysfunction (which is common with biliary obstruction/cholangiocarcinoma) are lorazepam, oxazepam, or temazepam ("LOT" drugs), which are cleared by simple glucuronidation without active metabolites and are considered best tolerated in advanced liver disease - The Maudsley Prescribing Guidelines in Psychiatry, 15e, Table 8.5.

Additional practical concerns:

If the patient is on opioids for cancer pain (very likely in metastatic disease), combining with clonazepam raises the risk of additive sedation and respiratory depression.
Benzodiazepines as a class can precipitate encephalopathy in more advanced liver disease.
If short-term clonazepam is used anyway, keep it low-dose, time-limited (days, not weeks), and reassess frequently for oversedation/confusion, especially if bilirubin is rising or synthetic liver function is impaired.

What actually treats the itch (worth adding, not just sedating through it)

Based on palliative care and hepatology literature:

Bile drainage/biliary stenting if obstruction is the driver - often the most effective single intervention (Harrison's, Mulholland & Greenfield's Surgery).
Cholestyramine (bile acid sequestrant) - first-line in cholestatic itch (Robbins & Cotran Pathologic Basis of Disease).
Sertraline - considered by several palliative reviews as a reasonable first-line pharmacologic option for cholestatic pruritus, with the added benefit of improving mood/sleep.
Rifampicin, naltrexone (opioid antagonist), ondansetron - second-line options, though naltrexone can be tricky if the patient is on opioids for pain.
Gabapentin/pregabalin - evidence is weaker specifically for cholestatic itch but used for refractory pruritus generally.
Antihistamines are largely ineffective for this itch mechanism (not histamine-driven) - if you want a sedating agent that also has some evidence in cholestatic itch, sertraline at night or a short-acting non-active-metabolite benzodiazepine (e.g., lorazepam) would be more rational choices than clonazepam.

A recent systematic review (PMID: 36933112, Digestive Diseases and Sciences, 2023) on cholestatic pruritus treatment in PBC/PSC reinforces that bile-acid-targeted therapies and sertraline have the better evidence base; this is a related-disease population but the itch mechanism and treatment hierarchy are comparable to malignant biliary obstruction.

Bottom line

A short course of clonazepam for insomnia driven by itch is not contraindicated outright, but given likely hepatic impairment, lorazepam or a low-dose sertraline/mirtazapine at night would be preferred over clonazepam, and you should pair any sedative with a direct anti-pruritic measure (cholestyramine, sertraline, or biliary decompression) rather than relying on sedation alone to manage the symptom.
