There is no evidence for a difference in antiepileptic efficacy between phenobarbital and any other compared AED , yet no evidence for absolute efficacy .
No convincing evidence exists for an excess of behavioural adverse effects , over other AEDs , attributable to phenobarbital .
Masked studies of phenobarbital in childhood epilepsy have shown no significant differences in behavioural or cognitive adverse effects compared to other AEDs .
This is in contrast to the excess of such adverse effects reported in studies open to observer bias .
However , the one finding of reduction in cognitive ability associated with phenobarbital treatment for febrile convulsions remains a concern .
INTRODUCTION : Against a background of concern about the safety of new pharmaceutical products , there has been renewed interest in one of the oldest antiepileptic drugs ( AEDs ) , phenobarbital .
Although still in widespread use in developing countries , its popularity has slipped in Western countries over the past century , partly because of controversy about its adverse effect profile .
This critical review examines the evidence supporting its effectiveness and its associated behavioural adverse effects for febrile convulsions and childhood epilepsy .
A CONTROLLED STUDY OF PROFYLACTIC LONG‐TERM TREATMENT OF FEBRILE CONVULSIONS WITH PHENOBARBITAL
An unselected and representative series of 208 children admitted following their first febrile convulsion has been offered a continuous prophylactic treatment with phenobarbital . The treatment was started in 174 of the patients and planned to be given for 2 years . For various reasons – the major one being sideeffects – the drug was discontinued at different times before the end of 2 years in 59 patients , 31 are still in treatment and 84 have completed the course
