Impax Labs issued a voluntary recall of a single lot of Lamotrigine Orally Disintegrating Tablets (ODT) due to an error in packaging where the childproof shell-packs labeled 200mg may contain 100mg blister cards. 

Lamotrigine ODT is a phenyltriazine drug indicated as adjunct in partial seizures, Lennox-Gastaut syndrome, or primary generalized tonic-clonic seizures in adults and children (≥2 years); for conversion to monotherapy in adults (≥16 years) with partial seizures who are on carbamazepine, phenytoin, phenobarbital, primidone, or valproate as a single antiepileptic drug (AED).
