History
Before the advent of modern contraceptives, reproductive age women spent most of their time either pregnant or nursing. In modern western society women typically have about 450 periods during their lives, as compared to about 160 formerly.
Although it was evident that the pill could be used to suppress menstruation for arbitrary lengths of time, the original regimen was designed to produce withdrawal bleeding every four weeks to mimic the menstrual cycle.
Seasonale was first developed by Barr Pharmaceuticals, in collaboration with Eastern Virginia Medical School, under an agreement. The U.S. Food and Drug Administration (FDA) approved Seasonale in the United States on September 5, 2003. Barr Pharmaceuticals, its manufacturer, claimed at the time of Seasonale's approval that it would cost one dollar per pill. Seasonale is one of Barr Pharmaceuticals' 22 oral contraceptive products. Health Canada approved Seasonale in July 2007, and Paladin Labs began distributing it in Canada on January 4, 2008.
The FDA approved Lybrel for human consumption on May 22, 2007. Lybrel is currently available at pharmacies by prescription only.

Famous quotes containing the word history:
“The awareness that health is dependent upon habits that we control makes us the first generation in history that to a large extent determines its own destiny.”
—Jimmy Carter (James Earl Carter, Jr.)
“The foregoing generations beheld God and nature face to face; we, through their eyes. Why should not we also enjoy an original relation to the universe? Why should not we have a poetry and philosophy of insight and not of tradition, and a religion by revelation to us, and not the history of theirs?”
—Ralph Waldo Emerson (1803–1882)
“What we call National-Socialism is the poisonous perversion of ideas which have a long history in German intellectual life.”
—Thomas Mann (1875–1955)
