Very happy with service, it was user friendly for a person on the go that is not overly technically savvy. I was so pleased with the prompt and thorough response. I absolutely will be using this again!

What Yaz is and what is it used for?

Yaz is a combined contraceptive pill. It contains two types of hormones, oestrogen and progestogen (Ethinyloestradiol 0.020 mg and drospirenone 3 mg). It is used to prevent pregnancy and can be useful in the management of heavy/ painful periods, polycystic ovarian syndrome, premenstrual syndrome and acne. Yaz provides effective reversible contraception if taken correctly and good cycle control.

Yaz prevents pregnancy by:

  • Preventing ovulation (the release of an egg).
  • Causing the mucus at the cervix (neck of the womb) to thicken, preventing sperm from entering the womb.
  • Thinning the lining of the womb, making it more difficult for a fertilised egg to implant.

Contraceptive pills do not protect against sexually transmitted infections (STIs). You should always use a barrier method such as a condom to reduce your risk of STIs.
Here is some important information on the combined pill.

Important Medical Information

Who is this service suitable for?

This service can provide treatment for female (birth sex) patients who require contraceptive treatment to:

  • Prevent pregnancy
  • Regulate troublesome periods
  • Manage hormonal-related acne

You can apply for this treatment if you are aged between 17 and 49 years. A risk assessment will be carried out to determine if it is safe to prescribe this pill for you.

To use this service safely, we require up to date height & weight measurements and a recent blood pressure reading. If you have had a recent blood pressure check by your GP/ nurse, you can use this. If not, a reading from your local gym, pharmacy or home monitor can be used.

Finding the right pill for you can take a little trial and error. If you are experiencing significant side effects with your current pill, please let us know and we can advise on safe alternative options.

Please be aware, this service is not suitable if you have malabsorption problems from any cause, including after weight loss surgery (e.g. gastric band or sleeve). You should speak with your local GP or family planning clinic for contraceptive advice.

How do you take Yaz?

If this is your first time taking Yaz or you are restarting:

  • Start it on the first day of your next period and you will have full contraceptive cover immediately.
  • If you have not been sexually active since your last period, you can start it at any time of your cycle. If taken correctly, you will have full contraceptive cover after 7 days of pill-taking. You should use additional contraception during this 7 day lead in time.
  • If you are changing from another pill/ form of contraception, please contact us via your patient record for specific instructions.

There are 28 pills in each packet of Yaz; 24 light pink pills and 4 white pills.

The light pink pills contain hormones (active pills). The white pills do not contain hormones – they are inactive reminder pills.

Start at Day one on the labelled pill packet and follow the arrows to complete all the light pink pills, then the 4 white inactive pills at the end of the packet. Your new packet should then be started immediately, there is no break.

When you are taking the hormone free pills (white pills) you will usually have a bleed. The bleed may last for a few days and still be present when you are due to start your next packet of Yaz. You should always start your next packet on time, even if you are still bleeding.
It is essential that you take your pill around the same time every day.

What are the potential side effects of Yaz?
Yaz is very well-tolerated and most women do not experience side effects. In those that do, nausea, headaches and breast tenderness are the most common and usually settle quickly. Spotting between periods is also common and should settle within the first 3 cycles.

Occasionally skin changes such as acne, decreased libido (sex drive), altered mood and fatigue are reported.
If you develop any of these symptoms and they are persisting, or you are concerned, please speak with your doctor. There are many alternative pill options to consider.

Combined pills like Yaz can cause increases in blood pressure. It is not medically safe to take this pill if you have high blood pressure. A blood pressure check should be performed every 6 months to monitor for this as you are unlikely to have any symptoms.

For full details of the potential side effects of these medications, please ensure that you read the patient information leaflet that comes with your medication before you start to use it.

Does taking Yaz increase my risk of getting a blood clot?

Yes, taking a combined contraceptive pill increases your risk of developing potentially harmful blood clots, compared to non-users. The overall risk of a blood clot is very small and is significantly lower than if you were pregnant or during the postpartum period, but blood clots are potentially very serious and in very rare cases can be fatal.

You should see a doctor immediately if you develop any of the following symptoms when taking the combined pill:

  • Pain or swelling in the legs.
  • Severe chest pain.
  • Breathlessness or coughing up blood.
  • Bad fainting attack or collapse.
  • Unusual headaches or difficulty with speech or sight.
  • Numbness or weakness of a limb.

Yaz has a higher risk profile than some other combined contraceptive pills.

  • If a blood clot develops in the leg, it can cause deep vein thrombosis (DVT).
  • If it travels to the lung, it can cause a pulmonary embolism (PE).
  • If it travels to the heart, it can cause a heart attack.
  • If it travels to the brain, it can cause a stroke.

The risk of developing a blood clot is greatest in the months immediately after starting Yaz, or when restarting after a break of at least one month. This risk reduces over the first year of use and then remains stable. It is for this reason that frequent starting and stopping of Yaz should be avoided.
Other things that can increase your risk of developing a blood clot when taking Yaz include:

  • Being overweight.
  • Smoking.
  • Increasing age (from 35 years and older).
  • Having a family member with a blood clot ages < 45 years.
  • Postpartum (6-12 weeks post-delivery).
  • Reduced mobility (even temporarily).

The more of these risk factors that apply to you, the greater your risk.

Seek additional advice if you are:

  • having a procedure or surgery (of any type)
  • planning a long haul flight
  • planning a holiday to an area of high altitude
  • immobilised for a prolonged period of time

Further information about blood clot risk is detailed in the leaflet that comes with your medication. Please read this before you start this pill.

Can I delay my period using the Yaz pill?
If you are taking Yaz regularly, you can delay or prevent your period by skipping the hormone free (white) pills.
Once you have completed the 24 light pink pills in the packet, skip the 4 white pills and start a new packet immediately.
Some people will experience breakthrough bleeding during the second pill packet. This is nothing to worry about and will settle after you have bleed with your next pill-free break.
What happens if I forget to take Yaz?

The main concern about missing a pill is how this will affect your contraceptive protection. The more pills you miss the greater the risk of becoming pregnant. This risk is greatest if you miss a pill from the week before or the week after the white pills.

  • If your missed pill is less than 12 hours late:
    • Take the missed pill as soon as you remember and the next pill at the usual time. Continue with your pill packet as usual.
    • You will have full contraceptive cover and do not need to use additional contraception.
  • If your missed pill is more than 24 hours late:
    • Take the missed pill as soon as you remember and carry on with your pill packet as usual. You may need to take 2 pills together (Do not take more than one missed pill).
    • Use additional precautions for the next 7 days.
    • If you have more than 7 light pink pills left in your pill packet, then take your break as usual.
    • If you have less than 7 light pink (active) pills remaining in your pill packet, do not take the white pills (discard them) and start your next pill packet immediately. If you do not have a bleed at the end of the second packet, you should do a pregnancy test.
  • If your missed pill was within the first 7 light pink pills of your cycle and you had unprotected sex, then you should speak with a health care professional as you may need emergency contraception.
  • If you start your new pill packet more than one day late, you will need to use additional contraceptive protection for 7 days.
  • If you have unprotected sex during the 7 days you are not fully covered for contraception, you should speak with a doctor via online video consultation as you may need emergency contraception.

If you have missed more than one pill, please contact your doctor for advice.
Please consult the product information for further information on missed pills: Yaz
If you have any questions or concerns about this, please speak to a Healthcare Professional.
If you are using Yaz for reasons other than contraception, then missing a very occasional pill is of no significant consequence.
If you have any vomiting or watery diarrhoea, you must use extra precautions during the illness and for seven days after the illness ends.

Can I take other medications with Yaz?

Some medications (prescribed and over the counter), herbal remedies and supplements can interact with Yaz. This can cause contraceptive failure and increase the possibility of potential side effects.

Please seek advice from a healthcare professional (e.g. doctor, pharmacist or nurse):

  • Before starting any new medications, herbal remedies or supplements if you are taking Yaz.
  • If you are taking regular medication and are planning to start using Yaz (or any contraceptive).

Examples of some medications that can interact with Yaz include EllaOne (emergency contraceptive pill), St John’s wort, antiviral medications used to treat HIV/ AIDs, certain epilepsy medications, griseofulvin antifungal, rifampicin antibiotic (please note, other antibiotics do not affect Yaz).
