Keep in mind that some herbal medications, such as ginkgo biloba, St. Johns Wort, ginseng, and valerian root, may cause headaches.
Remember:
If you are not sure whether to take preventive medications for your migraine headaches, you can check the Health Encyclopedia (the link is on your doctor's home page).
As with all headaches, sure to keep a record of what triggers your headaches by making a copy of the Headache Diary and filling it out for a month or so.
Call or e-mail your doctor if your migraine headaches are not improving.
