NICE (National Institute for Health and Care Excellence) advise that doctors, nurses and pharmacists should:
"Ensure arrangements are in place to provide a course of oral emergency contraception in advance, in specific circumstances where the regular contraceptive method being used, for example, condoms or the pill, is subject to 'user failure'."
This means that your local pharmacy or sexual health clinic should always have the morning after pill in stock, just in case you need to use emergency contraception right away.
If you don't have any emergency contraception on hand and you need some right away, you can use the NHS Service Finder to locate a pharmacy or clinic near you. Although online pharmacies stock the morning after pill, online orders will not be fast enough.
As an online pharmacy, we keep the morning after pill available so you can stock up in advance, this means that you can keep a pill at home and take it as soon as you need to.
