Summary

Sufentanil is cleared by CYP3A4, so chloramphenicol may raise and prolong its levels. This may cause potentially fatal respiratory depression and excessive sedation.

What this interaction means in plain words

Chloramphenicol and Sufentanil sl can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.

Evidence level: Moderate

Why it happens

Chloramphenicol inhibits CYP3A4, decreasing sufentanil clearance.

What to do

Monitor respiratory rate and sedation closely, particularly when starting or stopping chloramphenicol. Reduce the sufentanil dose or use an alternative analgesic if the combination is necessary.
