ZTALMY is approved to be used adjunctively (taken with other antiseizure medications or ASMs) or as monotherapy (taken as single medication). In the clinical study, 98% of participants taking ZTALMY were also taking other seizure medicines. The most common ones were valproate, levetiracetam, clobazam, and vigabatrin. The study did not include every ASM approved for patients with epilepsy.
