Summary

Parecoxib is converted to valdecoxib, which is metabolized by CYP3A4 and CYP2C9. Topiramate's weak CYP3A4 induction might slightly lower valdecoxib levels, with little expected clinical effect.

What this interaction means in plain words

Parecoxib and Topiramate have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.

Evidence level: Low

Why it happens

Weak CYP3A4 induction by topiramate may modestly increase valdecoxib clearance.

What to do

No action is usually required; assess analgesic response and increase the analgesic plan if pain control is inadequate.
