If you received Cerazette® previously
Changing to Zelleta® is as simple as getting used to the new packaging – you’ll take the same number of tablets each month, and request repeat prescriptions in the same way as when you took Cerazette®.1,2 When taken correctly, Zelleta® is just as effective at preventing pregnancy as Cerazette®.3

Zelleta® contains the same active ingredients in the same amounts as Cerazette®, and is therefore considered to work in the same way.1—3

What Zelleta® tablets are and what they are used for

Zelleta® are used to prevent pregnancy. Zelleta® contain a small amount of one type of female sex hormone, the progestogen desogestrel. For this reason Zelleta® are called a progestogen-only-pill (POP), or a mini-pill. Contrary to the combined pill, the POP or mini-pill does not contain an oestrogen hormone next to the progestogen.

Most POPs or minipills work primarily by preventing the sperm cells from entering the womb but they do not always prevent the egg cell from ripening, which is the main way that combined pills. Zelleta® is distinct from other mini-pills in having a dose that in most cases is high enough to prevent the egg cell from ripening. As a result, Zelleta® provide high contraceptive efficacy.

In contrast to the combined pill, Zelleta® 75 micrograms Tablets can be used by women who do not tolerate oestrogens and by women who are breast feeding. A disadvantage is that vaginal bleeding may occur at irregular intervals during the use of Zelleta®. You also may not have any bleeding at all.
