Generic Name: Drospirenone and ethinyloestradiol
Product Name: Yasmin
Yasmin is an oral contraceptive, used to prevent an unintended pregnancy. Your doctor may also give you Yasmin for another reason; it can help clear up moderate acne and help with periods which are very heavy, painful or irregular.
If you have any questions about why you were prescribed Loette, please consult your doctor.
Yasmin is a combined oral contraceptive. It works by:
- Stopping the release of eggs from the ovaries;
- Thickening mucus secreted from the cervix, thus helping to stop sperm penetrating into the uterus and moving towards any released eggs;
- Changing the lining of the uterus to help stop implantation.
All of these actions work together to prevent unintentional pregnancy.
One tablet is taken at the same time every day.
Yasmin should be started on the first day of your period with an active tablet (yellow) from the green area. Take the tablet that matches the day of the week your period has started on (eg. on Monday take the yellow tablet MON). If this is done, then immediate protection is achieved and no other form of contraception is required.
Yo can also start Yasmin on days 2–5 of your period. However, an additional barrier form of contraception (eg. condom, diaphragm) is recommended until seven active tablets have been taken in a row.
If the tablet missed is one of the inactive tablets (white), no action needs to be taken and there is no change in the protection against pregnancy.
If you have missed more than one tablet, please ask your doctor for advice.
If you forget to take your tablet but remember within 12 hours, there is no effect on contraceptive protection if you take the missed tablet immediately and keep taking the tablets as usual.
If you remember more than 12 hours after the time you usually take Yasmin, then what to do differs depending on which week you are in. The most important rule is that seven days of active tablets are needed to protect against pregnancy. Take the missed tablet as soon as you remember, even if this means that you take two tablets at once. Then if you are in:
- Week One: Continue taking the tablets as normal. For the next seven days, use an additional form of contraception. If you have had sexual intercourse in the seven days before the tablet you have missed, there is a chance you may become pregnant. Please see your doctor immediately.
- Week Two: Continue taking the tablets as normal. If you have taken your tablets correctly in the previous seven days (not missed any tablets) then no extra contraception is required. Extra contraception is recommended if you have not taken your tablets correctly in the previous seven days.
- Week Three: Continue taking the tablets as per normal until you finish the third row of tablets. Then start a new packet of Yasmin in Row One, leaving no gap between them. This means you will miss your period for the month. No other form of contraception is required if you have been taking your tablets correctly for the seven days prior to the missed tablet.
Vomiting or diarrhoea
If you experiences vomiting or diarrhoea within 3–4 hours of taking an active tablet, you may not get the correct dose. The advice then is as if you missed a tablet.
Bleeding in row four may not occur in all women. Continue taking Yasmin as normal. However, if you do not get your period twice in a row, pregnancy should be ruled out before you continue with treatment. Please tell your doctor immediately.
Ask your doctor if you have any questions on how to use Yasmin correctly.
