These tabs are one of Few effective abortive treatments I have found for Cluster Headaches. For a shadow, i put one tab under my tongue so it will be absorbed through the mucous membranes. For an oncoming Cluster Headaches, I use three tabs immediately upon feeling an aura. For best results, I drink a little cold water first so that the tab will dissolve faster. It works within 5-10 minutes for me approx 60% of the time. If no results with 10min, I immediately proceed to a plan B before the CH gets out of control. Please note that these will Not prevent Cluster Headaches, only abort them. I always keep at least 6 tabs in convenient locations in my bedroom, car, pocket, etc. Rarely do I ever see reviews for Cluster Headaches so I hope that this helps for those who suffer from dreaded Cluster Headaches and I hope others will post detailed reviews (Good or Bad) on products they have tried for Cluster Headaches. Since few products effectively abort Cluster Headaches, it may be worth a try for migraines too.

I would give this zero stars if I could. It doesn't work at all for my husband at all. And he took a total of 8. What works very well for him is Migraine Blocker. But sadly, for some reason, iherb stopped carrying it anymore.
