Missed or late pills

The next step after a late or missed pill depends on which pill you take. Find the packet and its leaflet, then speak to a pharmacist if you are unsure what to do. You may need emergency contraception, so ask promptly if you have had sex that might not have been covered.

Start with the exact product

For a combined pill, the NHS says advice depends on the pill type, how many pills were missed and where you are in the pack, including the day and week. For a progestogen-only pill, the type and the time that has passed matter. The pharmacist needs the specific pill name to give reliable advice.

Have the packet beside you when you call or visit the pharmacist. Give the brand name, the time you last took a pill and what has happened since. If you are unsure of a time, say so. Write down a short timeline of what happened so you can talk it through.

Some combined-pill packs contain inactive, or dummy, tablets as well as active tablets containing hormones. The NHS describes these as a different colour in the pack. Keep the blister strip with you so the pharmacist can identify which tablet was missed; colour alone cannot tell you what to do without the product name.

Why advice from another country can differ

UK NHS information discusses traditional progestogen-only pills, desogestrel and drospirenone. US CDC guidance covers norethindrone, norgestrel and drospirenone. A missed-pill rule copied from a different product or country may therefore be the wrong rule for your pack.

Use the leaflet supplied with your medicine and the NHS page for the relevant pill type in the UK. In the US and elsewhere, ask your pharmacist or prescriber about the local product instructions. If the pack or leaflet is missing, tell the pharmacist the name you have rather than guessing at the type.

Asking about emergency contraception

Which emergency option is suitable depends on more than the missed pill. Both combined and progestogen-only pills can affect how some emergency contraception works. Tell the pharmacist or sexual health service which pill you usually take and when you have taken it recently, including any missed tablets.

Contact a pharmacist, sexual health clinic or GP today in the UK, or a pharmacist or clinician in the US and elsewhere, if pills have been missed and you have had sex that might not have been covered. Emergency contraception is more effective the sooner it is used. Give the dates of sex as well as the dates of missed pills.

Ask what to do about your usual pill and whether you need extra contraception. Check what follow-up the adviser recommends too. Follow the leaflet or the advice for your specific prescription; do not use this article to change your medicine schedule.

Vomiting and diarrhoea matter too

Illness can affect how the pill works even when you have taken it. Vomiting soon after a progestogen-only pill, or severe watery diarrhoea, can mean it does not work as intended. The NHS advises checking the exact pill type, the timing and its leaflet, or speaking to a pharmacist.

There is separate NHS advice for vomiting or diarrhoea while taking a combined pill. The advice differs for some brands, with extra precautions if you are ill near the pill-free break. Tell the pharmacist when you took the pill, when illness began, whether it is continuing and where you are in the pack.

If missed pills keep happening

Book with a GP or sexual health clinic in the UK, or your healthcare provider in the US and elsewhere, if you want to discuss another method. CDC recommends exploring alternatives with people who frequently miss progestin-only pills. Explain what makes the pill difficult to use and what you would prefer.

You can ask for the agreed instructions to be written down. Before the conversation ends, repeat back what you understand you need to do next and ask who to contact if you are still unsure. Keep that plan with the leaflet for your pack.
