-Pill for fewer periods approved in US
AP - The first birth control pill specially designed to reduce the frequency of women's periods - from once a month to four times a year - has been approved by the US government.
Hence the name: Seasonale.
The pills aren't a new chemical. They contain the same combination of low-dose oestrogen and progestin found in many oral contraceptives.
Nor is the idea of menstrual suppression new.
For decades, many doctors have told women how they can skip a period by continually taking the active birth-control pills in each month's supply and ignoring the week of dummy pills in each packet.
But Seasonale promises to make the option a little more convenient, with packaging that gives women 12 straight weeks of active pills and then a week of dummy pills for their period.
The Food and Drug Administration's approval means menstrual suppression could become more common in the US, as Seasonale's advertising alerts women to the option.
Seasonale isn't perfect, the FDA cautioned.
While women have fewer scheduled periods, studies show Seasonale users have about twice the risk of unexpected "breakthrough" bleeding between periods as woman taking conventional monthly cycle pills, especially in the first few cycles of use.
Also, 7.7 per cent of Seasonale users dropped out of studies of the drug citing unacceptable bleeding, compared with 1.8 per cent of women taking conventional monthly pills.
Some Seasonale users had so much breakthrough bleeding that their total days of bleeding over a year were no less with the new drug than with regular pills, FDA said.
The agency ordered that Seasonale's label state that women must weigh that inconvenience against fewer regular periods.
"Each woman will respond to this product somewhat differently," said FDA's Dr Scott Monroe.
"Some will find they respond entirely as the product was designed to function, and others will have increased intermenstrual bleedingto the extent that they choose not to continue with the product."
Maker Barr Laboratories plans to have prescription-only Seasonale in pharmacies in the United States by November to compete with other brand-name oral contraceptives, which sell for roughly $US$1 ($A1.55) a pill. Generic versions can cost half that amount in the US.
Seasonale also may be attractive to women who experience severe cramping, heavy bleeding and other menstrual-related symptoms, a number Barr estimates at 2.5 million in the United States.
But the National Women's Health Network says some Seasonale proponents falsely imply that limiting menstruation is generally healthier, a message the consumer group calls particularly unwise for young girls.
"We already have a lot of shame and stigma in this society about menstruation," cautions the network's Cynthia Pearson, who has asked Barr to ensure that Seasonale ads don't convey that impression.
During the menstrual cycle, fluctuations in oestrogen signal the uterine lining, or endometrium, to thicken in preparation for nourishing an embryo. If pregnancy doesn't occur, that excess lining is sloughed off, accompanied by bleeding.
The big safety question is whether four periods a year are enough to allow the uterus to shed any tissue that builds up.
A study by Eastern Virginia Medical School, which developed the three-month pill regimen, shows they are.
It tracked 682 women taking either Seasonale or regular monthly pills for a year. Seasonale proved equally effective at preventing pregnancy.
Side effects, too, were similar with the exception of breakthrough bleeding, which did decrease with each cycle of Seasonale use.
