This medication is used along with other treatment for certain blood vessel diseases (e.g., arteriosclerosis obliterans, Raynauds disease, Buergers disease, cerebrovascular insufficiency). It works by widening blood vessels to help increase blood flow (improve circulation) to certain parts of the body (such as the hands/feet, brain). This effect may help to decrease symptoms such as cold hands and feet, numbness, tingling, and decreased memory or judgment.
