Zelleta is part of the most common group of brands of progestogen-only pill that contain the hormone desogestrel. The most popular of these brands is Cerazette. This type of pill is really safe for nearly every woman, but like all desogestrel pills, some of us have issues with breakthrough bleeding as there is no oestrogen in the mini pill to help with cycle control.
What is in the Zelleta pill?
Alternative to Zelleta pill
This contraceptive sits in Group 1 and has the same hormonal ingredient as:
Zelleta is a small tablet you swallow daily that (unlike the combined pill) only contains one hormone – progestogen. It prevents pregnancy by making the fluid in your cervix thicker (which makes it more difficult for sperm to enter the womb), and preventing the lining of your womb thickening enough for a fertilised egg to implant in it. Zelleta can also stop ovulation. There are a few things that can stop the progestogen-only pill from working properly including vomiting, some medicines, or missing a pill. Take a look at our complete guide to the progestogen-only pill .
How to use the Zelleta pill:
Zelleta contains the hormone desogestrel and must be taken within 12 hours of the same time everyday. We recommend keeping your pill packet somewhere you look at everyday (like your makeup bag) to remind you to take it, or set an alarm on your phone. Zelleta is designed to be taken for 28 days with no break between packs. Depending on where you are in your cycle, you might not be protected against pregnancy straight away.

Coming off the pill is easy - you just stop taking it. When you do, you're no longer protected from pregnancy. If you want to stop the pill but do not wish to become pregnant then you might want to consider switching to another form of contraception before you stop taking your pill.

How safe is the Zelleta pill:
Zelleta is very safe for most women. One possible side effect is the development of small fluid-filled sacs (cysts) on your ovaries, but they are usually harmless and disappear without treatment. If you do become pregnant while you’re using the progestogen-only pill, there may be a small risk of an ectopic pregnancy. It's also important to remember that the pill does not protect you from STIs.
