Antiseizure medication (ASM) side effects are common in epilepsy care [1]. Tolerability is often studied in newly initiated epilepsy treatment, where early and intolerable side effects typically result in early ASM discontinuation [2]. A related, but separate, issue is the prevalence of side effects in persons with epilepsy after try-out of their ASM regimes. Residual side effects are not uncommon; milder symptoms can be considered tolerable by patients and physicians, particularly if an ASM results in seizure freedom.
