What is Estarylla?

Estarylla (pronounced “es-tar-ill-ah”) is a combined hormonal birth control. It’s a pill you take every day at the same time.

In combined birth control pills like Estarylla, you’ve got two hormones: an estrogen and a progestin. These trick your body into not doing the things it normally would to be pregnancy-ready.

Like ovulation. This is where the ovary releases an egg to be fertilized by sperm. Estarylla stops this from happening.

There’s the layering up of the wall in the uterus too. Estarylla makes sure your uterine lining stays thin. This means that an egg can’t implant there, but it also makes periods lighter.

And there’s the cervical fluid effect too. Estarylla thickens this, so sperm can’t traverse through as easily.

How effective is Estarylla?

Pretty darn. When you take Estarylla right, it’s over 99% effective. This means that Estarylla pregnancy rates for women who take it perfectly are less than one in 100, over 12 months of use.

But as we all know, life happens. Forgetting a pill occasionally is pretty common. For typical, “real-world” use, the effectiveness of combined pills like Estarylla is around 91%. So we’re talking nine in 100 women getting pregnant over the course of a year.

Are there many Estarylla generics?

There are. Other brands of the Estarylla pill include Mono-Linyah, Ortho-Cyclen, MonoNessa, Previfem, Femynor, Sprintec, Mili and VyLibra.

These pills all contain the same hormones in the same amounts. So technically, they should work the same in the body. The main difference is that they’re made by different companies, so the prices are different. Sprintec and Previfem are a little cheaper than the others.

Is Estarylla a combination pill?

Yes. Estarylla contains two hormones called norgestimate and ethinyl estradiol. These work in the body like natural hormones called progesterone and estrogen.

By altering the normal hormonal cycle your body goes through every month, they basically trick your ovaries into not releasing an egg. They also stop blood from settling on the uterine wall, so it’s harder for it to get thicker and accept a fertilized egg for implantation.

Something else they do is make cervical fluid thicker. This makes it more difficult for sperm to get through to an egg.

How to take Estarylla

Take Estarylla tablets exactly as described by the doctor. This will help Estarylla to be as effective as possible.

If you’re not already taking a birth control pill or using hormonal birth control, you can start taking Estarylla on the day you get your period (Day 1 start), or on the first Sunday following your period.

You’re covered against pregnancy from the first day of taking it if you go for a Day 1 start. If you’re choosing a Sunday start, you’ll need to use condoms for the first seven days of use to stay protected.

Switching from another pill? Take your first Estarylla on the same day your other new pill pack would have started. If you’re switching from the ring or the patch, start on the day that your next ring or patch would have been inserted or applied.

Estarylla comes in packs of 28 tablets. Take your pill at the same time each day.

Estarylla missed pill: What to do

What are the most common side effects with Estarylla?

Breast tenderness, nausea, headache and abdominal pain are listed as common side effects when starting Estarylla or similar pills.

Most medications carry a risk of side effects. With the pill, it’s typical for milder side effects to pass after a few weeks or months of use. But if you continue to have these side effects or find them uncomfortable, you let the doctor know.

What to do if you get Estarylla side effects

Are there other names for Estarylla?

Yes, there are a few Estarylla generics that do the same job.

These include: Sprintec, Previfem, Ortho-Cyclen, Mili and MonoNessa.

These pills all share the same hormonal ingredients as Estarylla in the same amounts, but the excipients (for example the pill colouring and other non-active components) may be different.

Is Estarylla the same as Sprintec?

What if I want a lower dose of Estarylla?


Make sure to read the package insert that comes with your medication before you take it.
