What is Zelleta?

Zelleta is a progesterone-only pill (POP) or mini pill which is taken once daily at the same time. Because it doesn’t contain oestrogen, it’s a pill that’s suitable for women who are sensitive to the hormone or who can’t take it. And you don’t need to take a seven-day, pill-free break when you use it either. Just take one pill at the same time each day.

How does the Zelleta contraceptive pill work?

Each Zelleta 75 mg tablet affects the body in three separate ways.

Firstly, it prevents an egg from being released, so even if a sperm were to reach it, there would be nothing there to fertilise. Secondly, by thickening cervical fluid it makes the neck of the womb extremely difficult for the sperm to pass, so even if an egg has been released, it can’t be fertilised.

How safe is the Zelleta pill?

Very safe. It’s a better option for women who can’t take combined pills, because of the oestrogen in them. For example, women who get migraines or who have a slightly higher risk of getting blood clots (so women who smoke and are over 35).

How effective is Zelleta?

Over 99%, if you take it in the right way. This means that fewer than one in 100 women taking it this way will get pregnant over a whole year.

As with any contraceptive pill, this does mean taking it at the same time each day. But Zelleta comes with a 12-hour missed pill window. The traditional progestogen-only pill only has a 3-hour missed window, so if you’re busy or a little forgetful, Zelleta might be just the treatment for you.

How to take Zelleta

Swallow one pill every day, at the same time, and you’ll be close to 100% protected against pregnancy.

As timing and daily use is key, each Zelleta pill in the strip has a day of the week marked above it. This helps you to keep track of what you have or haven’t taken.

How long does the Zelleta pill take to work?

It depends on when you start using it.

If you have not taken any hormonal contraception the previous day, you can get immediate benefits from Zelleta by taking the first pill on the first day of your period. If you take Zelleta on the second to fifth day of your cycle, you will need to take extra precautions by using a barrier contraceptive for seven days.

If you have taken another mini pill the day before starting to take Zelleta, your protection might be reduced for a short time when you switch, so use extra precautions (condoms) for the next seven days. If you’re switching from a combined pill to the mini pill, the same applies.

What if I miss a pill?

Don’t panic. There are a few things you can do to stay protected. If you remember to take the pill within 12 hours of its scheduled time, simply take it and carry on the next day as you normally would have. There is no need for any extra precautions.

Beyond 12 hours, take the missed pill as soon as you remember, even if this means taking two at the same time. You’ll then need to use a barrier contraceptive for seven days.

FAQ: Zelleta

Have something specific you want to know? Search our info below, or ask our experts a question if you can’t find what you’re looking for.

Zelleta and desogestrel: what’s the difference?

Not much. Desogestrel is the name of the hormone in the pill. Zelleta is the name given to the pill by the manufacturer. That’s basically the difference between the two names.

There’s only one dose: Zelleta 75 micrograms. It’s the same dose as other desogestrel pills like Cerelle and Cerazette.


What are Zelleta tablets used for?

In the first instance, Zelleta is a highly effective method of preventing pregnancy. But because of the hormonal changes it causes in the body, it can also be useful in other ways. For example, some women find it helps them regulate and manage symptoms of PMS, including pain and heavy bleeding.

Will I get a period on Zelleta mini pills?

A lot of women taking Zelleta do not get a period. This is often seen as a good thing if you use the pill to control issues with heavy menstrual bleeding.

Some women may get irregular bleeding or spotting. This is more common when you start using Zelleta and normally goes away after a few weeks. But if it doesn’t, let us know. We can discuss other pill options with you.

Can I stop taking Zelleta if I want to get pregnant?

Yes. The pill is a popular reversible method of contraception. Coming off Zelleta to become pregnant is easy, and shouldn’t have any long term effects on your ability to become pregnant.

Technically you’ll be able to become pregnant as soon as you stop using Zelleta, although it’s recommended that you wait until you’ve had one full normal cycle before trying to conceive.

Is there a link between Zelleta pill and weight gain?

Some women experience weight fluctuation when taking the pill. But contrary to popular belief, there isn’t much evidence to prove that using mini pills like Zelleta and weight gain are linked.
A review of evidence has yet to find a connection between the two, although side effects reported with the use of the Zelleta pill often cite weight changes as common (up to 1 in 10 patients).

What are the other options for mini pills?

If you’re taking Zelleta but want to change to something else because you’re experiencing side effects, there are some alternatives.

Zelleta is similar to Aizea, Cerazette and Cerelle - so switching to these wouldn’t be difficult.

But there are also norethisterone (found in Micronor and Noriday) and levonorgestrel (found in Norgeston) pills available. They’ll offer the same level of protection, but may be more suited to you if you get side effects on Zelleta.

Are there any other non-pill options?

Yes. A long term option for progestin-only contraception is the IUD (intrauterine device), which is inserted into the uterus. It can remain effective for up to five years.

There’s also something called the Depo-Provera shot, which is given every eight or 13 weeks.

But you can’t administer these types of contraception yourself, so you’ll need to go into a clinic to have them done by a healthcare professional.

Can Zelleta cause side effects?

There are common side effects associated with mini pill use that affect up to 1 in 10 users. These tend to be mild and short lived when they do occur and include headaches, digestive issues, mood changes and breast tenderness.

Spotting on Zelleta is fairly common when you first start using it.

Why should I buy Zelleta with Treated?

Finding the right contraceptive for you can be a bit overwhelming when there’s so much to choose from. We’ll help you select the right one. Tell us about your health and we’ll recommend treatments that are tailored just for you.

Once you’ve picked the birth control you want, you can also choose how much medication you need and how often you’d like it to be delivered. With our flexible subscription plans, you can change, pause or cancel at any time.

And when your prescription is due for renewal, we’ll reach out to you to find out if it’s still working the way that it should for you.
