What you need to know
Official guidance advises consistency in brand prescribing of anti-epileptic drugs
Sleep disorders are very common, can trigger seizures, affect the whole family, and can often be managed in primary care
Most children need a timely educational or neuropsychological assessment to inform an education and health care plan, and these can be initiated by parents or a special educational needs coordinator
Buccal midazolam is the preferred rescue drug in young people at risk of prolonged seizures
Routine blood tests, including monitoring of serum drug concentrations, are unnecessary
Children and adolescents with epilepsy are medically managed by paediatricians with expertise in the condition, but non-specialist doctors can also help these young people live a fuller life. In this update we focus on important issues that are sometimes misunderstood, particularly those with little published guidance or where new evidence or guidance has emerged. The advice applies mainly to children with common epilepsies attending mainstream schools. Children with complex epilepsy require specialist guidance.
Is it safe to switch between drug formulations?
Official guidance and discussions on social media are conservative on the question of switching1 between different products, while prescribers are encouraged to use cheaper generic drug treatments. On balance, we advise consistency in prescribing (in the UK it not uncommon for the pharmacy to have different formulations every time the patient goes to renew the prescription) because comparative bioavailability data are incomplete for every anti-epileptic drug.2 Only the 2016 EQUIGEN study3 showed that switching between branded and generic lamotrigine was safe. Furthermore, the different names, packaging, and appearance of alternative products may cause confusion, anxiety, or occasionally non-adherence when prescriptions are refilled.
Table 1 lists anti-epileptic drugs stratified by risk of switching, according to their therapeutic index and release characteristics.4
