I tested this in RMVX, so I'm not 100% sure it will work on 2k3, but if you open up the script editor...
Yeah, won't work in rm2k3, first and foremost, because it doesn't come with a script editor.
As for the problem, there's probably no simple way of just removing the flash, so your best bet would probably be to have a parallel process check if any of the heroes has been inflicted with the drain status, and then damage that hero directly by means of event scripting manually.
You'll need to do a tiny bit of trickery to make sure it only activates while walking as well, which can be done by checking if the heroes coordinates are changing between each iteration of the parallel process.
