Combined Pill

The combined pill uses oestrogen and progestogen each day to prevent ovulation and may also improve period-related symptoms. The combined pill is an oral contraceptive containing oestrogen and progestogen. Taken as directed, it mainly prevents ovulation and also changes cervical mucus and the womb lining. Different brands use different hormones and schedules. It does not protect against sexually transmitted infections, so condoms may still be useful.

Contraceptive protection depends on when you start the pack and whether you need back-up contraception, so follow the instructions supplied with your prescription. Period pain, bleeding patterns, or premenstrual symptoms may change after the first packs, while skin or unwanted-hair changes can take longer to notice. The pill is preventive contraception, not emergency contraception.

Some people notice nausea, breast tenderness, headaches, mood changes, or spotting when starting. These effects often settle, but a different formulation may suit you better. Seek urgent medical help for sudden chest pain, breathlessness, coughing blood, a painful swollen leg, or sudden weakness or speech difficulty, as these can signal a serious clot or another emergency.

You can use the combined pill for as long as it remains suitable and you want contraception or symptom control. A clinician should review it if your health, medicines, smoking status, or pregnancy plans change. You can stop when you choose, but ask how to switch methods so contraceptive protection is not left unplanned.

Take one pill at the same time each day, following the pack's active and break instructions. Vomiting or severe diarrhoea can affect absorption. Missed pills may reduce protection, and the correct advice depends on how many were missed and where you are in the pack. Some medicines and herbal products interact with hormonal contraception.

The combined pill may suit someone seeking reversible contraception who can safely use oestrogen. It may also be prescribed to help [Irregular Periods](/symptoms/irregular-periods/), [Painful Periods](/symptoms/painful-periods/), or [Excess Facial Hair](/symptoms/excess-facial-hair/). It may not suit people with certain migraine patterns, clot history, uncontrolled blood pressure, or other health factors; a clinician checks these first.

A clinician checks your medical history, medicines, blood pressure, pregnancy possibility, and preferences. Choose a start date, read the pack instructions, and use back-up contraception when advised. Take each active pill on schedule. If a pill is late or missed, use the leaflet or contact a pharmacist for tailored instructions.

There is no recovery period because the combined pill is taken at home. Spotting or nausea can occur during adjustment. Keep taking it as prescribed unless a clinician tells you to stop, and arrange a review if side effects persist, your bleeding changes significantly, or you develop a new health concern.

The combined pill can raise the risk of blood clots, and suitability varies with age, smoking, migraine history, blood pressure, and personal or family history. It may interact with other medicines. Tell a clinician about new symptoms before continuing, and seek emergency care for severe clot warning signs.

Alternatives include the [Progestogen-Only Pill](/treatments/contraception-and-family-planning/progestogen-only-pill/), [Hormonal Coil](/treatments/contraception-and-family-planning/hormonal-coil/), [Contraceptive Patch](/treatments/contraception-and-family-planning/contraceptive-patch/), or [Vaginal Ring](/treatments/contraception-and-family-planning/vaginal-ring/). For symptom-focused care, your clinician may also discuss treatment of [Endometriosis](/conditions/endometriosis/) or [Polycystic Ovary Syndrome](/conditions/polycystic-ovary-syndrome/).

A family doctor, gynaecologist, sexual-health clinician, or pharmacist can assess whether the combined pill fits your health and goals. Bring your medicine list and mention migraine, clot history, smoking, breastfeeding, and pregnancy plans. Ask how to start, what to do after a missed pill, and when a review is needed.
