Drugs that have been found to work well as abortive agents are ondansetron (Zofran, an antinausea drug) and sumatriptan (Imitrex, an antimigraine drug).
For example, corticosteroids are very effective against pain caused by inflammation and swelling, and sumatriptan (Imitrex) was developed to treat migraine headaches.
Some prescribed abortive medications include the triptan drugs such as sumatriptan (Imitrex), zolmitriptan (Zomig), naratriptan (Amerge), and ergotamine tartrate and caffeine (Caffergot).
