The effectiveness of lamotrigine as a monotherapeutic agent for a variety o
f pediatric epilepsies was reviewed retrospectively. Children were categori
zed as having focal us generalized epilepsy and according to whether they w
ere antiepileptic drug naive or drug exposed. Data collected included dosag
es, side effects, length of follow-up, number of prior drugs, and treatment
response. Treatment was considered successful if the patient was seizure f
ree for 6 months or more. Eighty-three children were identified (average ag
e = 8.7 years); 43 had focal epilepsy, 32 had generalized epilepsy, and eig
ht were not classified. Twenty-nine patients were classified as having spec
ific syndromes. Fourteen patients were drug naive. The median follow-up per
iod was 8 months (mean = 8.5), Overall, 45% were seizure free, 44% with foc
al epilepsy and 36% with generalized epilepsy. All children with juvenile m
yoclonic epilepsy and benign rolandic epilepsy of childhood were seizure fr
ee, although not all had been treated for at least 6 months. One third of d
rug-naive patients were seizure free. Rash was the most common side effect
and was reported in five patients (6%); two patients discontinued the drug.
None had Stevens-Johnson syndrome, One quarter of children experienced non
quantifiable improvements, namely increased alertness and improved behavior
regardless of seizure control. Lamotrigine is effective as a monotherapeut
ic agent in children for both focal and generalized epilepsies. Side effect
s are relatively uncommon. Lamotrigine may be an effective firstline agent,
