Yes, Marc is correct. Zenvia. My Neurologist had samples of it. It is supposed to help prevent flares, but I dont think it would help once you get the flare. I am waiting for my compounding pharmacy to make it without the quinidine for me-if I ever get it I will report back. You can also get neurontinin cream at a compounding pharmacy. i use a neurontin and flexeril cream with an anti-inflammatory in it too.
