A dial pack of birth control pills
Daylight saving time and birth control: In the U.S. tonight (2:00 AM Sunday morning November 1, 2009) is the end of daylight saving time for this year and we revert back to standard time by turning our clocks back one hour. For women on oral contraceptives shortening their pill time by an hour is not a problem. It’s in the Spring when the day we change back to DST we advance the clocks that some women on the pill might have a problem. Those women on a very low dose pill (one with 20 mcg of estrogen or less) or who are on the mini-pill (the progestin-only-pill or POP) and who are over weight could have a decrease in their hormonal protection by taking their pill an hour later. Women on the shot, patch or ring receive hormones continuously and don’t have to worry about the precise timing when replacing those methods.
