WA sign that a combination hormonal contraception can now be provided with more information about its effectiveness with new leaflets issued by the Family Planning Association.
Recipes for full year KB will also be more available if guidelines are followed.
Dr Diana Mansour, Vice President for Clinical Quality of the School of Sexual and Reproductive Health, said: "This guideline suggests that by taking fewer hormone-free intervals – or shortening them to four days – it is possible that women can reduce their risk of becoming pregnant with combination hormonal contraception."
New NICE accredited clinical guidelines present the latest contraception with the work of researchers and some doctors who have advised patients not to take breaks between pill packages, which are usually issued in line 21 with labels for the days of the week. .
Professor Anne MacGregor said: "If a woman is late in restarting her pill package, she is at risk of experiencing a pregnancy.
"It is also beneficial for other symptoms, for example women do not need to experience headaches caused by a decrease in hormones."
Despite a shift in the medical profession, the researchers admit there is still confusion that must be had because most combination pills are still packaged in line 21 or contain a number of placebos, which means there are not enough pills in one package every day of the month.
Combination pill packages often remind women to take a break after each package.
Professor MacGregor said: "The difficulty is that the pill is mostly marketed as a 21-day regimen, seven days off, so it is very difficult for everyone to say there is no benefit to rest when actually what women prescribe says 21/7.
Professor Guillebaud added: "How is it possible for 60 years, we have taken the pill in a way that is not optimal because of the desire to please the Pope?"
