How does the Yaz work?

Yaz works in the same way as other combined oral contraceptives by preventing ovulation. Yaz makes it harder for sperm to get through to the womb and reach an egg and also thins the endometrium, so there is a reduced possibility of an egg attaching and developing.

How do I take Yaz?

There are two ways to start Yaz, which are explained in the package leaflet. It's important to take the medication exactly as instructed, as neglecting to take pills, or taking them at the same time as certain other medicines may reduce the effectiveness of the medication. You should take Yaz at the same time each day.

Is Yaz effective?

When taken correctly, Yaz is over 99% effective at preventing pregnancy.

What are the main side effects?

Many women do not have any side-effects. The most common side effects of Yaz are nausea (feeling sick), sore breasts, headaches, and spotting (bleeding between periods). These side effects usually go away within two or three months.

Are there risks in taking Yaz?

Women taking the oral contraceptive pill such as Yaz have a small increased risk of thrombosis (blood clot). However, this risk is smaller than the risk of a blood clot if you were pregnant. There are certain women who should not take Yaz so it is important to read the package leaflet carefully. Yaz should not be used in combination with any medication that increases the levels of potassium in the body. So long as you make a full disclosure on our medical consultation form then we can make sure that Yaz is still appropriate for you.
