experiences in MOS, or not responding to RIZATRIPTAN, after discontinuing years of,sumatriptans???

Hi - Thanks so much for posting your question. We'd very much like to help you. I'd be grateful if you'd be willing to clarify your question so that we may be better able to answer it. I'm sorry but I'm not sure what you mean by MOS. And you are saying you are not responding to Rizatriptan (maxalt) after years of taking a break from triptan medications in general? Is there a reason you stopped taking Triptans in the first place? Have you had success with other treatment options?
We look forward to learning more about your situation in hopes we can provide you with information and support. Warmly - Holly - migraine.com team
