Sumatriptan
"This is a comment about my own use, this stuff is a joke because the box only comes with 6 single shot nasal sprays, meanwhile during a cluster period I'll get from 3 to 6 excruciatingly painful Cluster headaches in a 24 hour period. Box will cure Basically 6 headaches, which lasts no more than 3 or 4 days during cluster period and that's while trying to conserve. The problem is most insurance will only pay for 1 box per month which leaves me missing work and banging my head against the wall for the other 25-27 days of the month. I don't know who made this medicine and why they would market it for clusters knowing that when people are in a cluster attack period get up to 6 or 7 "Suicide Headaches" per day. Terrible overall medicine."
