What is the Cimizt pill?

A combined pill packing two hormones that help to stop you getting pregnant. They do this by fooling the body into thinking it’s already ovulated, so it doesn’t ovulate. These hormones also change the texture of the uterine wall, so any stray fertilised eggs can’t catch on there and develop. They also alter the consistency of the mucus that’s released in the cervix so sperm can’t shoot through.

So two hormones, doing three jobs.

Some women also take combined pills like Cimizt for acne, as a kind of secondary reason (in addition to preventing pregnancy).

How effective is Cimizt?

Over 99%. We know, over 99% should technically be 100%. But it’s only ‘over 99%’ because it’s somewhere between 99 and 100. This means that out of 100 women taking the pill, over a year, less than one will get pregnant.

That’s with perfect use by the way. So taking it every day, like you’re supposed to, and not making any mistakes. Making the occasional error when taking the pill reduces this rate of effectiveness a little, to around 91%.[1] So it’s best to take it like it says.

What dosages of Cimizt tablets are there?

Just the one: Cimizt 150/30. It’s a pretty common formulation you can get in other pills. If you want to switch doses, you’ll need to move on to a different pill, because there’s no Cimizt Lo or Cimizt 20.

Gedarel 20, Munalea 20, Mercilon and Bimizza are very like Cimizt, only with less oestrogen. So if you get side effects like dry vagina, mood swings or low sex drive, you might be better on a lower oestrogen dose. Your prescriber can help you find the right pill during your consultation.

What you need to know about Cimizt

What is Cimizt used for?

Contraception primarily. It’s very effective at this (over 99% when taken right). It’s quite flexible in that, compared to other forms of contraception, it’s both reliable and reversible. So you can stop taking Cimizt any time to start trying for a baby.

It may also help to reduce the symptoms of PMS (premenstrual stress) and treat acne.

How to take Cimizt

Cimizt is a 21-day pill. You’ll take one pill, once a day, at the same time, for 21 days continuously. Then have a seven day break, and move onto the next pack and repeat.

It’s best to work taking the pill into your routine, so you’re less likely to forget it. For example, you might take it before going to bed, or before you brush your teeth in the morning.

What to do if you miss a Cimizt pill

What are the most common side effects on Cimizt?

Some more common side effects reported among women using Cimizt include: headaches, weight gain, mood changes, tender breasts and digestive issues.

Milder side effects will tend to pass after you’ve been using Cimizt for a few months. But if you find that these stick around for longer, let your clinician know. They might be able to suggest an alternative treatment that works better for you.

When to see a doctor about side effects

Are there other pills that are similar to Cimizt?

Yes. Gedarel 30, Munalea 30 and Marvelon have the same hormones as Cimizt in the same amounts. Gedarel, Mercilon and Munalea also come in a lower dosage of 20/150, which contains a reduced amount of the synthetic version of oestrogen. These may be better for women who take Cimizt and find they get mild oestrogenic side effects (dry vagina, mood swings or loss of libido).

There are other combined contraceptive pills that include other forms of the synthetic hormones. If you get a lot of side effects with Cimizt, you may be recommended a different type of combined pill or be advised to take the mini pill instead.

Is there a non-pill alternative to Cimizt?
