Should I use this page, or skip it?
Use this page if you take a contraceptive pill in the UK and have missed one, taken one late, been sick, or had severe diarrhoea. Skip it if you need a same-day decision after unprotected sex — go to a pharmacist or sexual health clinic now, not after a long read. This page cannot give a single rule that fits every brand.
Call 999 for severe one-sided pelvic pain, collapse, or heavy bleeding with dizziness. A missed pill is paperwork and timing; those symptoms are not.
Why is there no one missed-pill rule?
Combined pills and progestogen-only pills work differently. Some progestogen-only pills must be taken within 3 hours, others within 12 hours. Missing pills near a hormone-free break on a combined pack is not the same as missing one in the middle of a pack.
Guessing from a friend’s brand is how people end up pregnant. Identify the packet name first, then use the matching NHS page or the leaflet in the box.
What should I do in the next hour?
Find the packet. Note the brand, whether it is combined or progestogen-only, how many pills were missed, and whether you had sex since the missed dose. Take the most recently missed pill if the NHS or leaflet for that brand says to — do not take a handful to “catch up” unless the instructions say so.
Then open the NHS missed-pill page for your type, or ask a pharmacist. Find a GPhC-registered pharmacy on Pick My Pharmacy. Sexual health clinics can also advise and offer emergency contraception.
When do I need emergency contraception?
When the missed-pill rules say you may not be protected and you have had sex. That window is hours to a few days, not “wait until Monday.” The copper IUD is the most effective emergency method up to 5 days after sex. Emergency pills have shorter windows.
If you use ulipristal (ellaOne), ask when it is safe to restart your regular pill — it can interact. Levonorgestrel has different restart advice. Do not mix instructions from two packets.
How do I get back on my regular pill?
Follow the restart and extra-precaution advice for your brand. That often includes condoms for a set number of days. If you are in the hormone-free week of a combined pack, the NHS page may tell you to skip the break — only do that if it is the instruction for your situation.
If you keep missing pills, a longer-acting method such as an implant or coil may fit life better. That is a clinic conversation, not a failure.
Do pharmacy schemes differ across the UK?
Emergency contraception from a pharmacy is widely available, but funding and age rules vary by area. England, Scotland, Wales and Northern Ireland also run different minor-illness pharmacy schemes; a missed pill is usually a medicines-advice question, not Pharmacy First. Ask locally. 111 in England, Scotland and Wales can signpost; Northern Ireland uses GP out-of-hours.
Who should skip this page?
Skip this page if you need emergency contraception today — go and get it. It is not a pregnancy test result, not an abortion guide, and not permission to skip condoms with a new partner. STIs are a separate risk; see the sexual health hub if exposure is the worry as well as pregnancy.
Common questions about missed contraceptive pill
- Should I take two pills after missing one?
- Sometimes the instructions say to take the most recently missed pill, which can mean two in one day. That is not a universal rule. Follow the NHS page or leaflet for your exact pill rather than a social-media shortcut.
- Do I need emergency contraception?
- It depends on pill type, how late you were, how many pills were missed, where you are in the pack, and whether you had sex. Ask the same day because emergency options are time-sensitive. A pharmacist can often advise.
- How long should I use condoms afterwards?
- The extra-protection period differs by pill and situation. The NHS missed-pill advice or a pharmacist will give the number of days for your pack. Do not assume seven days covers every brand.
- What if I am sick or have diarrhoea?
- Vomiting soon after a pill, or severe diarrhoea, can mean the dose was not absorbed. Treat that as a missed pill and follow the same brand-specific advice. A pharmacist can help you match the timing.
- Where can I get emergency contraception quickly?
- Many pharmacies, GP surgeries and sexual health clinics provide it free. The copper IUD is the most effective option up to 5 days after sex. Find a GPhC-registered pharmacy on Pick My Pharmacy, or use a sexual health clinic.
