Side effects of the Cerelle pill

Cerelle contains a progestogen and does not contain oestrogen. Hormonal changes can alter the lining of the womb, so bleeding may become unpredictable, lighter, more frequent or absent. This change does not by itself show that contraception has failed, but missed tablets, vomiting or medicine interactions can affect protection.

Some people notice headache, nausea, breast discomfort, acne, altered mood or changes in sex drive. These effects can have other causes too. Cerelle is different from a combined pill; a prescriber can explain the distinction and whether another option is appropriate for you.

Take the tablet at the same time each day and follow the instructions supplied with your prescription. Record bleeding and other symptoms for a few weeks, including missed tablets, new medicines and whether symptoms settle. A pharmacist can check interactions and what to do after vomiting or a missed dose.

Do not stop Cerelle without arranging another contraceptive plan if pregnancy prevention matters to you. A clinician can discuss alternatives and may assess unrelated causes of painful periods, irregular periods or pelvic symptoms rather than assuming the pill is responsible.

Arrange a review for persistent troublesome bleeding, severe or repeated headaches, significant mood changes, breast changes or possible pregnancy. Seek urgent help for severe abdominal pain, fainting, sudden weakness, chest pain, trouble breathing, coughing blood or a painful swollen leg.

Ask whether your bleeding pattern is expected, how to manage a missed tablet, and whether another medicine could interact. You can also ask how Cerelle compares with the combined pill and which option fits your medical history.
