What is Qlaira used for?

Qlaira is a combined contraceptive pill used to prevent pregnancy. It’s also licensed to treat heavy menstrual bleeding (known medically as heavy menstrual bleeding or HMB) in women who want to use oral contraception at the same time.

Unlike most contraceptive pills, which contain a fixed dose of hormones in every active tablet, Qlaira uses a quadriphasic dose schedule. This means the hormone levels in each tablet change across the 28-day wallet, more closely mimicking the natural hormonal fluctuations of the menstrual cycle.

Each wallet contains 28 pills: 26 coloured pills in four different shades, each with a different hormone combination, plus 2 white inactive tablets. Tablets are taken in a set order every day without a break between wallets.

How does Qlaira work?

Qlaira contains two hormones, estradiol valerate (an oestrogen) and dienogest (a progestogen), which work together to prevent pregnancy in three ways:

  1. Stopping ovulation: the hormones prevent your ovaries from releasing an egg each month. Without an egg, pregnancy can’t occur.
  2. Thickening cervical mucus: this makes it much harder for sperm to reach an egg.
  3. Thinning the womb lining: this reduces the chance of a fertilised egg implanting and developing.

For heavy menstrual bleeding, the hormonal combination helps regulate and thin the womb lining, which reduces the volume of bleeding each cycle.

Who can take the Qlaira contraceptive pill?

Qlaira is suitable for women of reproductive age who want a combined oral contraceptive pill, and who may also want to manage heavy menstrual bleeding at the same time.

It isn’t suitable for everyone. Don’t use Qlaira if you:

  • Have or have ever had a blood clot in your legs, lungs, or other organs
  • Have a blood clotting disorder such as protein C deficiency, protein S deficiency, antithrombin-III deficiency, Factor V Leiden or antiphospholipid antibodies
  • Have ever had a heart attack or stroke
  • Have ever had angina or a transient ischaemic attack (TIA)
  • Have severe diabetes with blood vessel damage, very high blood pressure, very high cholesterol or triglycerides, or hyperhomocysteinaemia
  • Have or have ever had migraines with aura
  • Have liver disease where your liver function hasn’t returned to normal, or have ever had a liver tumour
  • Have or are suspected of having breast cancer or cancer of the genital organs
  • Have unexplained vaginal bleeding
  • Are allergic to estradiol valerate, dienogest, or any other ingredient in Qlaira

Speak to your doctor before using Qlaira if you have a family history of breast cancer, diabetes, depression, Crohn’s disease, ulcerative colitis, epilepsy, varicose veins, or if you have recently given birth. Your doctor will assess if Qlaira is appropriate based on your medical history and any risk factors you may have.

How to Take Qlaira

Take 1 pill every day at roughly the same time every day, following the direction of the arrow on the wallet. You can take it with or without food.

  1. Before you start your first wallet, attach the weekday sticker strip that begins on the day you plan to start. This lets you see at a glance whether you’ve taken your tablet each day.
  2. Start with tablet 1 and take one tablet each day in order, following the arrows.
  3. When you finish the wallet, start a new one the very next day with no break, even if you are still bleeding.

Each wallet contains 28 pills: 26 active pill tablets in four colours (each with a different hormone combination) and 2 white inactive tablets at the end. Take all 28 in order.

Withdrawal bleeding usually starts when you reach the second dark red tablet or the white inactive tablets. It’s not unusual for some bleeding to continue into the first days of your next wallet.

If you’re starting Qlaira for the first time and haven’t used hormonal contraception in the past month, begin on the first day of your period. If you’re switching from another combined pill, ring, or patch, or from a progestogen-only method (sometimes called the mini pill), speak to your doctor or pharmacist for guidance on when to start and if you need additional contraception during the changeover.

Qlaira Pill Side Effects

Like all medicines, Qlaira can cause side effects, though not everyone will experience side effects. Most are mild and tend to settle after the first few months of use.

If you experience any severe or persistent side effects, or any signs of a blood clot such as sudden leg pain or swelling, breathlessness, chest pain, or sudden changes in vision or speech, seek urgent medical attention.

Warnings and Precautions

  • Using a combined hormonal contraceptive like Qlaira slightly increases the risk of developing a blood clot in a vein or artery. The risk is highest in the first year of use and when restarting after a break of 4 or more weeks. Seek urgent medical attention if you notice signs of a blood clot, including leg pain or swelling, sudden breathlessness, chest pain, or sudden changes in vision or speech.
  • Qlaira doesn’t protect against HIV or any other sexually transmitted infection. Use condoms if there is any risk of infection.
  • Some medicines can make Qlaira less effective, including certain epilepsy medications (such as phenytoin, carbamazepine and barbiturates), rifampicin for tuberculosis, some HIV and hepatitis C treatments, antifungals such as griseofulvin, and the herbal remedy St John’s Wort. Always tell your doctor or pharmacist you are taking Qlaira if any new medicines are prescribed.
  • If you vomit within 3 to 4 hours of taking a tablet or have severe diarrhoea, the tablet may not have been fully absorbed. Follow the missed pill guidance in the patient information leaflet and use additional contraception if needed.
  • Tell your doctor you are taking Qlaira if you need surgery or will be immobile for a long period, as it may need to be temporarily stopped to reduce the risk of blood clots.
  • Some women experience mood changes or depression while using hormonal contraceptives. If you notice changes in your mood, speak to your doctor.
  • The pill may cause irregular bleeding, particularly in the first few months. If unexpected bleeding occurs for more than 3 months in a row or starts after several months of regular cycles, speak to your doctor.
  • Tell your doctor or laboratory staff you are taking Qlaira before any blood tests, as oral contraceptives can affect the results of some tests.
  • Keep Qlaira out of the sight and reach of children. No special storage conditions are required. Don’t use after the expiry date shown on the wallet.
  • Don’t dispose of Qlaira via wastewater or household waste. Ask your pharmacist for advice on safe disposal.

Qlaira Contraceptive Pill Reviews

Qlaira FAQs


Acne is listed as a common side effect of Qlaira in the patient information leaflet, meaning it may affect up to 1 in 10 users. Some women find their skin improves on combined hormonal contraceptives, while others notice it worsens. If acne is a concern for you, speak to your prescriber before starting Qlaira – they can help you find the most suitable option.

If you take it correctly, Qlaira is 99% effective in preventing pregnancy. If it’s not taken correctly, around 9 out of 100 women will get pregnant. Effectiveness depends on taking the pill consistently, following the correct order, and being aware of what to do if a tablet is missed or if you’re unwell. Speak to your doctor or pharmacist if you have questions about how to get the best protection from Qlaira.

Qlaira is one of the few combined contraceptive pills licensed specifically to treat heavy menstrual bleeding not caused by a disease of the womb. If you want to use oral contraception and also manage heavy periods at the same time, Qlaira may be suitable. Your doctor will assess if it’s the right option based on your medical history.

You can buy the pill online from Click2Pharmacy after completing a short consultation. Our licensed pharmacists will review your answers and, if suitable, prescribe Qlaira and arrange your treatment for quick, discreet delivery.

Qlaira works differently from most contraceptive pills and isn’t used in the same way to delay periods. Because each wallet contains a specific sequence of tablets that must be taken in order, skipping the inactive pill tablets or running packs together isn’t recommended without speaking to your doctor first. If you need to delay your period, speak to your doctor about the most appropriate option.

Qlaira shouldn’t generally be taken while breastfeeding. If you want to use the pill while breastfeeding, speak to your doctor first, as they can advise on the most suitable contraceptive option for you at this time.

Most common over-the-counter painkillers such as paracetamol and ibuprofen aren’t known to interact with Qlaira. However, always check with your pharmacist before taking any new medicine alongside Qlaira, including herbal remedies, as some can affect how well it works.

Qlaira isn’t suitable for use as emergency contraception. If you need emergency contraception, speak to your pharmacist or doctor as soon as possible.

If you start taking Qlaira on the first day of your period, you’re protected against pregnancy straight away. If you start on any other day, or switch from another method, additional contraception such as condoms may be needed for the first 9 days. Speak to your doctor or pharmacist for guidance specific to your situation.

If you’re less than 12 hours late, take the missed Qlaira pill as soon as you remember and continue as normal.

If you’re more than 12 hours late, take one Qlaira pill immediately, continue taking the remaining tablets at the usual time, and use additional contraception such as condoms for the next 9 days.

If you’ve missed more than one Qlaira tablet, contact your doctor. Refer to the missed pill chart in your patient information leaflet for full guidance based on which day of the wallet the tablet was missed.
