Tonic Clonic Management
First line: sodium valproate
Second line: lamotrigine or carbamazepine
Valproate: Teratogenic, so patients need careful advice about contraception Liver damage and hepatitis Hair loss Tremor
Focal Seizures TX
One way to remember the treatment is that the choice of medication is the reverse of tonic-clonic seizures:
First line: carbamazepine or lamotrigine
Second line: sodium valproate or levetiracetam
Carbemazepine:
Agranulocytosis
Aplastic anaemia
Induces the P450 system so there are many drug interactions
