Anyone with a dog whose had multiple seizures in a day? Can they recover?

So my dog had a lot of seizures within 24 hours (14 in last 6 hours) it happens every 20 to 30 minutes. we had only one severe one where he couldnt even stand the other are lighter ones for around 23s, we took him to vet, got prescribed medicine but nothing changed.. Anyone had something like this before?
