MHRA/CHM Advice: Antiepileptic Drugs: updated advice on switching between different manufacturer’s products for a particular drug (November 2017)1
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 – A General Overview’).
