Timing

Multiple antiepileptics is common for refractory epilepsy. Maintain exact timing consistency — even small blood level fluctuations can trigger breakthrough seizures. Many antiepileptics are strong enzyme inducers/inhibitors that affect each other's levels. Your neurologist should monitor drug levels regularly.

Risk factors

Higher risk for: those on multiple antiepileptics (enzyme induction/inhibition), liver impairment, elderly, pregnant individuals (teratogenicity concerns), or those with recent dose changes.
