Yasmin is a contraceptive pill and is used to prevent pregnancy.
Each light-yellow tablet contains a small amount of two different female hormones, namely drospirenone and ethinylestradiol.
Contraceptive pills that contain two hormones are called “combination” pills.
Yasmin contains both drospirenone and ethinylestradiol; drospirenone is a type of progestogen and ethinylestradiol is a type of oestrogen.
These active ingredients work together in three ways:
- The Prevent the ovaries from releasing eggs, therefore stopping ovulation
- They thicken the vaginal fluid to prevent sperm from reaching the womb
- They make the womb walls thinner, so if an egg were to be released, it would be unable to attach itself to the womb
How to take it
- Take Yasmin every day for 21 days
- Yasmin comes in strips of 21 pills, each marked with a day of the week.
- Take your pill at the same time every day.
- Start by taking a pill marked with the correct day of the week.
- Follow the direction of the arrows on the strip. Take one pill each day, until you have finished all 21 pills.
- Swallow each pill whole, with water if necessary. Do not chew the pill.
- Then have seven pill-free days
After you have taken all 21 pills in the strip, you have seven days when you take no pills. So, if you take the last pill of one pack on a Monday, you will take the first pill of your next pack on the Tuesday of the following week.
Within a few days of taking the last pill from the strip, you should have a withdrawal bleed like a period. This bleed may not have finished when it is time to start your next strip of pills.
You don’t need to use extra contraception during these seven pill-free days – as long as you have taken your pills correctly and start the next strip of pills on time.
Forgotten the pill
- If you are less than 12 hours late taking a tablet, the protection against pregnancy is not reduced. Take the tablet as soon as you remember and then take the following tablets again at the usual time.
- If you are more than 12 hours late taking a tablet, the pregnancy protection may be reduced. The greater the number of tablets you have forgotten, the greater is the risk of becoming pregnant.
The patient leaflet inside the packet has more information on what to do if any pills are missed.
If you have forgotten any of the tablets in a strip, and you do not have a bleeding during the first tablet-free period, you may be pregnant. Contact your doctor before you start the next strip
What to do in the case of vomiting or severe diarrhoea
If you vomit within 3-4 hours of taking a tablet or you have severe diarrhoea, there is a risk that the active substances in the pill will not be fully taken up by your body. The situation is almost the same as forgetting a tablet. After vomiting or diarrhoea, take another tablet from a reserve strip as soon as possible. If possible take it within 12 hours of when you normally take your pill. If that is not possible or 12 hours have passed, you should follow the advice given above, under “If you forget to take Yasmin”
Like all medicines, this medicine can cause side effects, although not everybody gets them. If you get any side effect, particularly if severe and persistent, or have any change to your health that you think may be due to Yasmin, please talk to your doctor.
Yasmin like other combined oral contraceptives can increase the risks of developing blood clots (thrombosis) in all women.
The chance of having a blood clot may be higher if you have any other conditions that increase this risk.
Your risk is higher:
- If you are very overweight (body mass index or BMI over 30kg/m2);
- If one of your immediate family has had a blood clot in the leg, lung or other organ at a young age (eg. below the age of about 50). In this case you could have a hereditary blood clotting disorder;
- If you need to have an operation, or if you are off your feet for a long time because of an injury or illness, or you have your leg in a cast.
- As you get older (particularly above about 35 years)
- If you gave birth less than a few weeks ago.
Common side effects include:
- depressive mood
- headache, migraine
- breast pain
- breast tenderness
- bleeding between periods
- vaginal yeast infection
Uncommon side effects include:
- breast enlargement
- altered interest in sex
- high blood pressure, low blood pressure
- vomiting, diarrhoea
- acne, severe itching, skin rash, hair loss (alopecia)
- vaginal infection
- fluid retention
- body weight changes
The risk of developing a blood clot increases the more conditions you have.
Air travel (>4 hours) may temporarily increase your risk of a blood clot, particularly if you have some of the other risk factors as well.
It is important to tell our doctor when you complete the health assessment form, if any of these conditions apply to you, even if you are unsure.
Alternatives to Yasmin include:
Other hormonal options – the hormonal patch or the hormonal coil are two options that work very similarly to pills like Yasmin. They have most of the same benefits as Yasmin but because you don’t take them orally, they’re less likely to give you stomach problems like vomiting or diarrhoea.
Progesterone-only contraception – progesterone-only contraception like the mini pill can still be very effective. As they don’t have oestrogen in, it means there are no risk of oestrogen-related side effects and risks such as blood clots and weight gain
