## Supporting information

Additional information

  Sodium valproate (Epilim??, Episenta??) and the related drug valproic acid (Depakote??, Convulex??) are anticonvulsant medications used in the treatment of epilepsy. They are also used for treatment of bipolar disorder and as prophylaxis for migraine.

  Topiramate (Topamax??) is an anticonvulsant medication used in the treatment of epilepsy and as prophylaxis for migraine.

  Exposure during pregnancy to either valproate or topiramate is a known cause of birth defects. As it is not possible to know whether an individual donation will be transfused to a pregnant woman, donors taking any form of sodium valproate, valproic acid or topiramate must be deferred until at least 1 week after stopping treatment.

Reason for change:
  A deferral has been added for donors taking topiramate. The name of the entry has been updated to reflect this.
