Hi Seven,
Here are some medications to try if "nothing" work:
- methotrimeprzin (levomepromazin in UK) 2 to 5 mg if strong pain, up to 4 times a day. It can be increased up to 15mg 4 times a day if you tolerate the sleepiness
- frovatriptan is a brother of sumatriptan. It last more than 24 hours and can used in a preventive way. 2,5 to 5 mg a day. It won't necessarily abort a crisis but it will attenuate it.
- dihydroergotamine 1mg IV daily for 3 to 10 days. Can also be given IM or SC
- indomethacin 75 to 150 (250) mg per day (divided in 3 doses) (but not if you take lithium or steroids)
Maybe you tried them but if not, you can dicuss them with your doctor.
Good luck!
