Yasmin pill
"A combined contraceptive pill that’s highly effective in preventing pregnancy. To take it, you’ll need an annual blood pressure and weight check."
What is Yasmin?
The Yasmin pill is a combined oral contraceptive. When you take it correctly, it’s 99% effective in preventing pregnancy.
How does it work?
The Yasmin contraceptive pill contains the hormones ethinylestradiol (oestrogen) and drospirenone (progesterone). Together they work to prevent pregnancy by:
- Stopping your ovaries from releasing an egg (ovulation).
- Thickening the mucus in your cervix to make it harder for sperm to reach an egg.
- Thinning the lining of the womb, so an egg is less likely to implant itself.
How to take Yasmin
Most women choose to take one daily Yasmin pill for 21 days, with a 4 or 7 day break before they start the next pack. You’re likely to have a withdrawal bleed during this break.
- Continuous use is taking one Yasmin pill daily without a break.
- Tricycling is where you take a daily pill for 9 weeks without a break (three packs of pills). After these 9 weeks you take a 4 or 7 day break, then start the cycle again.
- Flexible extended use means taking one pill daily for at least 21 days. If you experience heavier bleeds and would rather have a shorter bleed window, you can take a 4-day break instead of 7. On day 5 start taking the pill daily again, and continue for at least 21 days without another break.
Our clinicians will advise on how to use the pill.
Effectiveness
When taken correctly, the Yasmin combined pill is 99% effective in preventing pregnancy. In cases where it’s not taken exactly as prescribed, it can lead to pregnancy for around 9 out of 100 women. So it’s important to follow advice and instructions.
If you’re vomiting or have severe diarrhoea while taking this pill, you may not be protected against pregnancy. So use condoms along with continuing to take the pill as usual. If the vomiting continues for more than 24 hours, follow the same steps as you would for a missed pill.
Important: you should only start taking Yasmin birth control pills if you’re certain you aren’t pregnant.
Side effects of Yasmin
As with all medications, some women may experience side effects when taking Yasmin. These can include mood swings, headaches, sore breasts, feeling sick and irregular bleeding. In rare cases, some women develop raised blood pressure or blood clots.
For full details of side effects and correct use, please see the Yasmin pregnancy pills patient information leaflet. And if you’re worried about side effects, including blood clots, you can contact us in your Patient Record.

Yasmin pill FAQs
-
How long does Yasmin take to work?
If you start taking Yasmin on days 1-5 of your period, this should give you immediate protection against pregnancy.
However, if you start taking Yasmin after day one and you have a short or irregular menstrual cycle, you’ll need to use extra barrier contraception like condoms for 7 days if you have sex. We’ll advise you on this during your online consultation.
-
Does Yasmin stop periods?
It’s possible to avoid having a period if you take 2 packets of Yasmin back-to-back. Our clinicians can advise on delaying your period using contraceptive pills.
If you decide to come off the Yasmin pill you may find you have no period, or bleeds are irregular, and it can take 3 months for them to get back to normal.
-
Who can take Yasmin?
You should talk to your clinician about alternative birth control options and not take Yasmin if:
- You have, or have ever had, a blood clot in a blood vessel of your legs (deep vein thrombosis, DVT), your lungs (pulmonary embolus, PE) or other organs.
- You have a blood clotting disorder.
- You have, or have ever had, a heart attack or stroke.
- You have very high blood pressure.
There are other instances where the pill is not suitable, and our clinicians can advise on this during your online consultation.
Can smokers use Yasmin?
Smokers under 35 should be able to take Yasmin. However, if you’re a smoker over 35, you’ll be advised to try alternatives like the progestogen-only pill, intrauterine device (IUD), intrauterine system (IUS), contraceptive implant or the contraceptive injection.
-
Can I take Yasmin while breastfeeding?
As with most combined contraceptive pills, if you’re breastfeeding, you should wait for 6 weeks after giving birth before taking Yasmin.
-
What if I miss my Yasmin pill?
If you miss one pill at any point in your pack or start a new pack 1 day late, you’re still protected from pregnancy.
Here’s what to do:
- Take the missed pill as soon as possible, even if it means taking 2 pills on the same day.
- Continue taking the remaining pills at your regular schedule.
- If you normally have a pill-free break, stick to your usual timing.
If you’ve missed two or more pills (over 48 hours late), your contraceptive protection may be reduced.
Follow these steps:
- Take the most recent missed pill right away, even if it means taking 2 pills in one day.
- Skip any other earlier missed pills.
- Use additional contraception, like condoms, for the next 7 days.
- Continue with your pack as normal.
- You may need emergency contraception if you have had unprotected sex after missing pills.
When you finish the pack after missing pills:
- If there are 7+ pills left in your pack: Finish the pack as usual and take your 7-day pill-free break as planned.
- If fewer than 7 pills are left in your pack: Skip the pill-free break and start a new pack immediately.
You may need emergency contraception if:
- You’ve had unprotected sex after missing pills.
- You had unprotected sex in the 7 days before the missed pills.
Our clinicians can prescribe emergency contraception, if it’s safe to do so. For full details of correct use and what to do if you miss a pill, please see the Yasmin patient information leaflet. If you need more advice you can contact us in your Patient Record.

What to do if I get Yasmin side effects
As with all medications, some women may experience side effects when taking Yasmin. You should talk to your doctor if you get any side effects you think are related to Yasmin, especially if they’re severe and persistent.
-
Yasmin warnings
Combined contraceptives can raise your blood pressure, which can be dangerous. So, it’s important to check your blood pressure before starting the treatment, then once a year after that.
As part of your consultation, we’ll ask you if you’ve had your blood pressure checked recently, or checked it yourself at home using a blood pressure monitor. This information is required before we can prescribe combined contraceptives like Yasmin.
-
Yasmin drug interactions
You should be able to take Yasmin alongside other medications. So that our clinicians can prescribe it safely, you’ll need to let us know which prescription, over-the-counter medicines and recreational drugs you’re taking regularly.
-
