Recommendations are made for both minimizing the likelihood of serious rash and for management of rash in patients taking LTG. Risk of serious rash may possibly be lessened by strict adherence to manufacturer's dosing guidelines, particularly in patients who are at higher risk: those on concurrent VPA and in the pediatric population.

In response to increasing cost pressures, healthcare systems are encouraging the use of generic medicines. This review explores potential problems with generic substitution of antiepileptic drugs (AEDs). A broad search strategy identified approximately 70 relevant articles. Potential problems with generic substitution included: The limited evidence (mainly case reports with some pharmacokinetic studies) appears to support these concerns for older AEDs. As a result, restrictions on use of specific generic AEDs are in place in some countries and recommended by some lay epilepsy organisations. As more AEDs lose patent protection, it is important to examine the question of whether generic substitution may pose problems for patients with epilepsy, and whether there should be safeguards to ensure that both physician and patient are informed when generic substitution occurs.

We studied 13 episodes of nonconvulsive generalized status epilepticus (NGS) in 10 adults. The syndrome may start in middle or late life and is often mistaken for psychiatric disorders. Some patients have shown good retention of language abilities, except for reduced fluency, despite impairment in other higher functions. In most patients, the syndrome recurs for several years despite anticonvulsant therapy. Transitional cases of NGS with lateralizing EEG features exist, and some cases are probably due to secondary generalization from a temporal or frontal focus.
