When I had a foster dog that seized, the emergency vet (university vet school hospital) sent us home with a needle-less syringe containing an emergency dose of diazapam, in case she seized again. Our instructions were to insert it rectally and deliver the full dose during the seizure, if she seized. We had to keep it with us until she was adopted, and then give it to her adopters to keep on hand.
Her post-ictal period lasted a few days, and she was very wobbly and uncoordinated. It was so bad that we feared that she wasn't long for this world. Regular short walks helped her recover from that--the rhythmic motion of walking seemed to help her brain shake the cobwebs and recover her motor skills. She's doing just fine now.
FWIW, anti-seizure meds worked very, very well for that dog.
