-
Qlaira is a combined oral contraceptive pill made by Bayer Plc that is used to prevent pregnancy and regulate heavy menstrual bleeding.
Qlaira contains 5 types of pills, 4 types are active and contain different levels of estradiol valerate and dienogest, and the other type is inactive pills. This means Qlaira mimics the natural levels of hormones in your body during a menstrual cycle.
You take 1 pill each day for 28 days with no break, and may have a short withdrawal bleed when you take the 2 inactive pills.
You can get Qlaira from Asda Online Doctor by filling out a quick and easy questionnaire online. One of our doctors will then check if Qlaira is right for you. Get your Qlaira pills delivered in discreet packaging or collect them from an Asda Pharmacy.
About Qlaira
-
-
Qlaira is a combined oral contraceptive pill containing the active ingredients estradiol valerate (oestrogen) and dienogest (progesterone). It is used to prevent pregnancy and can also be used to improve heavy and painful periods. It contains different types of pills with different levels of hormones to mimic your natural cycle. This is different to many other combined pills, which contain the same dose throughout your 28-day cycle.
-
-
Qlaira works by mimicking your body's natural hormone levels to prevent pregnancy by:
- thickening the cervical mucus to stop sperm from getting through
- preventing ovulation by stopping an egg from being released from the ovaries
- thinning the lining of the womb to make it harder for a fertilised egg to implant
Qlaira is a quadriphasic pill. That means it has 4 types of active pills that contain a different amount of hormones over a 28-day cycle. It is designed to mimic the body’s natural menstrual cycle by gradually adjusting the hormone dose in the active pills, followed by 2 inactive pills.
Each active pill is a different colour depending on which level of hormone it contains. Each pack includes:
- 2 dark yellow pill containing 3mg of estradiol valerate
- 5 medium red pills containing 2mg estradiol valerate and 2mg dienogest
- 17 light yellow pills containing 2mg estradiol valerate and 3mg dienogest
- 2 dark red pills containing 1mg estradiol valerate
- 2 white pills containing no hormones, called inactive pills
How long does Qlaira take to work?
How long Qlaira takes to work will depend on when you take your first pill.
If you take Qlaira on day 1 of your period, you will be protected from pregnancy straight away. If you start taking Qlaira on any other day, or are changing from a different contraceptive, it takes 9 days for it to be effective, and you should use other methods of contraception, such as condoms, during that time to prevent pregnancy.
How effective is Qlaira?
Qlaira is more than 99% effective at preventing pregnancy when taken correctly. However, the pill is normally around 91% effective with regular, real-life use because of things like missed pills, sickness, or diarrhoea.

-
To take Qlaira, you should swallow 1 pill whole with water, with or without food, at the same time every day. Each Qlaira pack contains 28 pills, split into 4 types of active pills that contain different hormone amounts and 1 type of inactive pills without hormones. There are 26 active coloured pills that contain hormones and 2 inactive white pills that do not. To take Qlaira, you should:
- Choose the weekday sticker strip of the same day you begin Qlaira. For example, if you start on a Monday, you should use the sticker strip that says ‘MON’. You should put this sticker on the top of the blister strip so that your first day is marked with ‘1’.
- Take each pill on the day it is marked, in the correct order.
- Take 1 pill every day for 28 days and then start a new pack without a break.
You may experience withdrawal bleeding around day 26 to 28 when you take the second dark red pill or the 2 white pills. You should start the next pack of Qlaira even if you are still bleeding.
-
-
If you forget to take any of the active pills (any colour but white), and are less than 12 hours late, you should take your pill as soon as you remember and will still be protected against pregnancy.
If you forget to take your Qlaira active pill and are more than 12 hours late, the day you missed the pill/s in your packet will decide on what to do next. Please follow the instructions in the table, check your patient information leaflet, and speak with a pharmacist or doctor if you’re still not sure.
You should not take more than 2 active pills on the same day.
Missed Qlaira pill What to do Days 1 to 17
Take the missed pill straight away, then take the next one as planned. Continue as normal with the rest, even if you have to take 2 pills in 1 day.
✓ Use extra contraception, like condoms, for the next 9 days.
Important: If it’s days 1 to 9 and you had sex in the last 7 days before missing your pill, speak to a doctor as there’s a chance of pregnancy.
Days 18 to 24
Skip the missed pill and start a new blister strip, taking pill 1 as soon as you can. Discard the remaining missed pills from your old strip
✓ Use extra contraception, like condoms, for the next 9 days.
Days 25 or 26
Take the missed pill when you remember and continue as normal with your strip.
✗ You do not need to use extra contraception.
Days 27 or 28
Leave the missed pill, taking the remaining pills as normal. If you miss the last pill of the strip, leave it and continue with the new strip as planned.
✗ You do not need to use extra contraception.
Missed more than 1 pill?
The more pills you have forgotten, especially on days 3 to 24, and the closer you are to the inactive pill phase, the greater the chance of pregnancy if you have had sex.
✓ Speak to your doctor straight away.
If you are sick or get severe diarrhoea
If it’s 3 to 4 hours after taking an active tablet, the pill may not be fully absorbed by your body. Take the next pill as soon as possible and within 12 hours of when you normally take it.
If 12 hours have passed or you continue to be ill, follow the advice in this section as if you have missed a pill.

Frequently asked questions
Is Qlaira a combined pill?
Yes, Qlaira is a combined pill. It contains 2 synthetic hormones, estradiol valerate (oestrogen) and dienogest (progesterone). Combined pills always contain oestrogen and progesterone but may have different synthetic types or doses.
Does the Qlaira pill help with acne?

Acne is also a commonly reported side effect of Qlaira, so some people may also see their acne get worse.
Does the Qlaira pill help with heavy periods?

Can I use Qlaira to skip my period?
Yes, you may be able to use Qlaira to skip your period. However, because it is a phasic pill and each pill contains a different level of hormone, you will need to speak with a doctor about how.
