No you are correct. Axert and other triptans like imitrix, zomig, maxalt, frova, amerge) have only been approved and had saftey studies done on them for 4 uses a month. However, I know of many people who suffer from cluster headaches for several days that last into months or years and they take it several times a day. If the drug companies ever wanted to test the long term effects of their drugs they should contact people who suffer from cluster headaches and get like 8 ha a day. I found from long term daily use that I had anxiety attacks from it but that was about it. My heart still works fine. Its all about how much you need, what your dr is willing to perscribe and what your insurance is willing to cover.
