I keep referencing rescue medications. Turns out not everyone knows what that is! Not everyone with epilepsy needs one, and there are rescue meds for other conditions-nitroglycerin for angina, for example.
For me, a rescue medication is something taken as needed to stop clusters of seizures. I try to take half a clonazepam during an aura since most of my seizures bring company.
That doesn't always prevent a seizure, but it seems to reduce severity and duration of what does happen. Having a rescue medication has made living a very active life easier because it can be the difference between a cluster of 3 and a cluster of 30 seizures.
