Advice in the perioperative period
Elective and emergency surgery

Patients should be advised to take their regular medications on the day of surgery.
Abrupt withdrawal of any anticonvulsant drug should be avoided.
Confirm with the patient if they need to be maintained on a specific manufacturer’s product (see Further information).
Post-operative advice
Regular dosing of the patient’s usual oral medication should be re-established as early as possible post-operatively.
If patients are unable to take their regular oral medication post-operatively, consider using the intravenous route. The intravenous dose and frequency should be the same as the established oral dose.

MHRA/CHM Advice: Antiepileptic Drugs: updated advice on switching between different manufacturer’s products for a particular drug (November 2017)
Brivaracetam is a category 3 antiepileptic, hence it is usually unnecessary to ensure that patients are maintained on a specific manufacturer’s product as therapeutic equivalence can be assumed. However, other factors are important when considering if switching is appropriate such as patient anxiety, risk of confusion or dosing errors. (For more information see Antiepileptics overview.)
