Cerazette progestogen-only pill: what to know

Cerazette can alter the lining and cervical mucus and can suppress ovulation. Bleeding may become irregular, lighter, more frequent, or absent. Headache, nausea, breast tenderness, acne, or mood changes may occur, but symptoms that concern you should be assessed rather than attributed automatically to the pill.

It does not prevent sexually transmitted infections. Medicines for seizures, tuberculosis, HIV, and some herbal products can affect hormonal contraception, so provide a complete medicines list before starting or continuing it.

Take one tablet each day in the order shown, using an alarm or another dependable reminder. If you are late, miss a tablet, vomit, or have severe diarrhoea, use the Cerazette leaflet or speak to a pharmacist promptly because the next steps depend on the timing.

Tell your prescriber about unexplained bleeding, liver disease, breast cancer, pregnancy, and any planned medicine changes. Keep condoms available if backup protection is advised.

Seek urgent help for sudden chest pain, difficulty breathing, coughing blood, fainting, new one-sided weakness, or a painful swollen leg. Arrange prompt medical advice for severe abdominal pain, a positive pregnancy test, heavy bleeding, or side effects that are difficult to manage.

Ask when Cerazette becomes effective for you, what counts as late, how to manage sickness, and whether your medicines interact with it. If you are comparing methods, ask how it differs from the combined pill.
