YAZ is a combined oral contraceptive, commonly known as a ‘birth control pill’ or ‘the Pill’.
YAZ is used to prevent pregnancy.
It is also used to treat moderate acne in women seeking oral contraception and to treat symptoms of premenstrual dysphoric disorder (PMDD).
You may also experience the following benefits:
- more regular, shorter and lighter periods
- a decrease in anaemia (iron deficiency)
- a decrease in period pain
- improvement in symptoms like bloating, swelling or weight gain related to fluid retention
Some conditions such as pelvic inflammatory disease, ovarian cysts, ectopic pregnancy, fibrocystic breast changes and cancer of the uterus (womb), and ovaries may be less common in women taking the Pill.
When taken correctly, it prevents you from becoming pregnant in several ways, including:
- inhibiting the egg release by stopping it maturing
- changing the cervical mucus consistency, making it more difficult for the sperm to reach the egg.
YAZ has 24 active (hormone) tablets and 4 inactive tablets, rather than the traditional 21 active tablets and 7 inactive tablets. This means that with YAZ, you take the active (hormone) tablets for three more days. This helps your hormone levels to stay even.
When the Pill is taken by women under close observation in clinical trials, it is more than 99% effective in preventing pregnancy. However, in real life the Pill is around 92% effective. This is because pills might be missed, or taken with medicines that may interfere with their effectiveness.
Like all oral contraceptives, YAZ is intended to prevent pregnancy. It does not protect against HIV infection (AIDS) and other sexually transmitted diseases.
Yaz tablets are a type of hormonal contraception commonly known as ‘the pill’ or combined oral contraceptive pill. Yasmin tablets contain two active ingredients, ethinylestradiol and drospirenone. These are synthetic versions of the naturally occurring female sex hormones, oestrogen and progesterone. Ethinylestradiol (previously spelt ethinyloestradiol in the UK) is a synthetic version of oestrogen and drospirenone is a synthetic form of progesterone.
Combined oral contraceptives like Yaz work by over-riding the normal menstrual cycle. In a woman’s normal menstrual cycle, levels of the sex hormones change throughout each month. The hormones cause an egg to be released from the ovaries (ovulation) and prepare the lining of the womb for a possible pregnancy. At the end of each cycle, if the egg has not been fertilised the levels of the hormones fall, causing the womb lining to be shed as a monthly period.
The daily dose of hormones taken in the pill work mainly by tricking your body into thinking that ovulation has already happened. This prevents an egg from ripening and being released from the ovaries each month.
The hormones also increase the thickness of the natural mucus at the neck of the womb, which makes it more difficult for sperm to cross from the vagina into the womb and reach an egg. They also change the quality of the womb lining (endometrium), making it less likely that a fertilised egg can implant there.
Yaz is a monophasic pill. This means that each active tablet has the same dose of hormones in it. One active tablet is taken every day for 24 days and then one inactive tablet for the next four days. During these four days, the levels of the hormones in your blood drop, which results in a withdrawal bleed that is similar to your normal period. You start the next pack as soon as you finish the four inactive tablets, even if you are still bleeding.
