What is the combined pill done with?

The oestrogen and progestogen are delivered together in each active tablet in many combined-pill formulations. Their combined action mainly prevents ovulation and also changes cervical mucus, making it harder for sperm to pass. The progestogen component can alter the lining of the womb as well. Different brands may use different hormone amounts or a different progestogen, so the name on your prescription matters. The combined pill does not protect against sexually transmitted infections.

Take the pill according to its pack instructions and use the advice given for missed tablets or vomiting. Tell a prescriber about migraine with aura, previous blood clots, high blood pressure, liver disease, smoking, breastfeeding, and every medicine or supplement you use. Some medicines can affect contraceptive protection. A clinician can help choose a formulation and explain whether you need additional contraception when starting or changing packs.

Seek urgent medical help for sudden chest pain, difficulty breathing, coughing blood, one-sided leg swelling or pain, sudden weakness, or a new severe headache with neurological symptoms. Contact your prescriber about persistent troublesome bleeding, marked mood changes, or symptoms that began after starting the pill. Do not restart a combined pill after a serious reaction without medical advice.

Ask which oestrogen and progestogen your pack contains, what to do after a missed tablet, which medicines interact with it, and whether your health history makes another contraceptive more suitable.
