How you get itPrescription only — available free from Lyng Pharmacy under the NHS service

The combined pill contains oestrogen and progestogen, and works mainly by stopping ovulation. It is highly effective when taken consistently. At Lyng Pharmacy we can supply and manage it free on the NHS under the pharmacy contraception service.

How to take it

One pill daily at roughly the same time. Traditional packs run 21 days followed by a seven-day break, but continuous or extended regimens — taking packs back to back, or shortening the break to four days — are now recognised as safe and often better, with fewer bleed-related symptoms.

When starting, if you begin on day one to five of your period you are protected immediately. Starting at any other time, use condoms for the first seven days.

Missed pills

One missed pill (up to 48 hours late): take it as soon as you remember, continue as normal, no extra protection needed.

Two or more missed pills: take the most recent one, continue the pack, and use condoms for seven days. If those seven days run past the end of the pack, skip the break and start the next pack straight away. If you missed pills in the first week and had sex in the previous seven days, emergency contraception may be needed — come and speak to us.

Vomiting within three hours of a pill, or severe diarrhoea, counts as a missed pill.

Who should not take it

Migraine with aura — the combined pill is not suitable, because of stroke risk. If you develop aura while taking it, stop and speak to us or your GP promptly.

Side effects and warning signs

Headaches, nausea, breast tenderness, mood changes and spotting are common in the first few months and usually settle.

Seek urgent medical help for calf pain or swelling, chest pain or breathlessness, coughing blood, severe headache or a first migraine with visual symptoms, weakness or numbness on one side, or sudden vision loss.

Some medicines reduce its effectiveness, particularly enzyme-inducing drugs for epilepsy and HIV, and St John’s wort. Ordinary antibiotics do not — though vomiting or diarrhoea while unwell can.

Always read the label. This page is general information, not advice for your situation. Doses, warnings and interactions differ between products and between people. Check the leaflet inside your medicine, and ask our pharmacist if anything is unclear — that conversation is free and takes two minutes.

Frequently asked questions

What do I do if I miss a combined pill?
One missed pill: take it and carry on. Two or more: take the most recent, use condoms for seven days, and skip the pill-free break if it falls within those seven days.
Can I take the combined pill if I get migraines?
Not if you get migraine with aura — the stroke risk makes it unsuitable. Migraine without aura may be acceptable; ask us.
Do antibiotics stop the pill working?
Ordinary antibiotics do not. Vomiting or diarrhoea while unwell can, as can enzyme-inducing medicines and St John’s wort.
Can I skip my pill-free break?
Yes. Continuous and extended regimens are recognised as safe and often cause fewer bleed-related symptoms. Ask us about the options.
