A recently licensed type of emergency contraception may offer women protection from pregnancy even when taken five days after sex.
Scottish researchers found that ulipristel acetate worked well after the three-day limit of the most commonly used drug, levonorgestrel.
At present ulipristel - unlike levonorgestrel - is only available with a prescription.
The British Pregnancy Advisory Service welcomed the study.
Emergency contraception uses hormones to either prevent the release of an egg by the ovary in the hours after sex, or stop it implanting into the the womb.
Levonorgestrel is available from pharmacies, either with a prescription, or sold directly to over-16s.
A study by specialists working for NHS Lothian tested the effectiveness of levonorgestrel and ulipristel (which was licensed for use last year) using a sample of more than 1,600 women from the UK, Ireland and the USA.
A total of 2.6% of the levonorgestrel group became pregnant despite taking the drug, compared with 1.8% in the ulipristel group.
In a much smaller group of women who received emergency contraception more than three days after sex, there were no pregnancies among women who had taken lipristel compared with three pregnancies among those taking levonorgestrel.
The levels of side effects were roughly the same in both two drugs.
'Time window'
However, researchers said that the newer drug cannot be sold 'over-the-counter' at pharmacies because it did not yet have the established safety record of levonorgestrel.
Ann Furedi, chief executive of the British Pregnancy Advisory Service described the new type of drug as "exciting news".
She said: "It offers a longer time window for use than the traditional, emergency contraception pill.
"Different hormones are involved to the ones traditionally used in contraception, so it may be that these will prove to have other contraceptive uses in future.
"However, accessibly is key to the uptake of any time-sensitive medication and since this pill is not currently available over-the-counter and is significantly more expensive to buy than the traditional 'morning after pill', it may be that many women who could benefit from it are not able to access it."

I was hoping it meant there was a limit to how many times a woman could get the pill. But then I realized, that would mean women would have to be responsible within their sexual activity and we wouldn't want to expect that of women since men clearly will never be held to the same standard by society...which is why the pill was created in the first place. See what happens when men are allowed to run things?
