Buy Zelleta
Zelleta is an oral contraceptive pill used to prevent pregnancy. It is a progestogen-only pill (POP), also known as the mini-pill.
Like other hormonal contraceptives, it won’t protect you against sexually transmitted diseases (STDs). To protect yourself from both STDs and pregnancy, you must also use a barrier method, such as a condom.
How Zelleta works
Zelleta contains the progestogen hormone desogestrel. It works primarily by preventing the sperm cells from entering the womb.
It also prevents the egg cell from ripening.
Directions
Always take Zelleta exactly as described in the patient information leaflet or as your doctor / Chemist4U pharmacist has told you.
If you forget to take Zelleta or have a severe bout of sickness or diarrhoea, refer to the patient information leaflet for guidance, as you might not be fully protected against pregnancy.
Each pack contains 28 tablets. The days of the week are printed on the back of the blister strip, with arrows on the front indicating the order in which you should take the pills. Every time you start a new pack of Zelleta, take a tablet from the top row. If you start the pill on a Wednesday, you must take the tablet from the top row marked as ‘WED’.
You should take 1 pill daily, preferably at the same time each day.
Swallow the tablet whole with water.
When you can start taking Zelleta
When no hormonal contraceptive has been used in the last month
Wait for your period to start. Take the first tablet from the blister strip on the first day of your period. You will not need to take extra contraceptive precautions.
You can also start taking Zelleta on days 2-5 of your cycle; however, you must use additional barrier method contraception, such as a condom, for the first 7 days.
Changing from a combined pill, vaginal ring or transdermal patch
You can start taking Zelleta the day after you take the last tablet from your current pill pack.
You can also start taking the tablets on the day your vaginal ring or patch is removed.
If your pill pack also contains inactive tablets, you can start taking Zeletta the day after taking your last active tablet.
You can also start taking Zelleta the day after your ring or patch has been removed or during a placebo tablet interval of your current contraception. You will, however, need to use a barrier method of contraception for the first 7 days.
When changing from another progestogen-only contraception method
You can stop taking your current pill any day and start taking Zelleta straight away. You will not need to use additional contraception.
When changing from an injectable, implant or progestogen-releasing intrauterine device (IUD)
You should start taking Zelleta when your next injection is due or on the day that your implant or your IUD is removed. You will not need to use additional contraception.
After having a baby
You can start taking Zelleta between 21 and 28 days after you have given birth. If you start taking it later, make sure to use a barrier method of contraception for the first 7 days.
If you have already had unprotected sex, you must ensure that you are not pregnant before taking Zelleta.
After a miscarriage or an abortion
You must ask your doctor for advice, who will tell you when to start taking Zelleta.
Side effects
Zelleta may cause side effects in some people, but these won’t affect everybody. Common side effects include:
- Decreased sex drive (libido)
- Depressive mood
- Change of mood
- Acne
- Headaches
- Nausea
- Breast pain
- Weight gain
- Irregular or no periods
If you experience any side effects, including any not included in the patient information leaflet, you can report them using the MHRA Yellow Card Scheme.
Serious side effects
Seek emergency medical attention if you notice any signs of a severe allergic reaction, symptoms of which include swelling of the face and throat, skin rash, breathing difficulties and/or loss of consciousness.
If you experience any of the following side effects, stop taking Zelleta and seek medical advice immediately:
- Severe pain or swelling in your legs, unexplained pains in your chest, breathlessness, an unusual cough, coughing up blood (symptoms of thrombosis)
- Sudden severe stomach ache or yellowing of the skin and whites of the eyes (jaundice)
- Sudden, severe pain in the lower abdomen or stomach area
- A lump in your breast
- Unusual, heavy vaginal bleeding
Breast cancer has been found slightly more often in women who take the pill compared to those who don’t. When you stop taking the pill, the risk will gradually decrease.
The risk of developing a blood clot in the legs or lungs is slightly higher in women taking the pill, although this is rare. The risk with progestogen-only pills is believed to be lower in comparison to women taking the combined pill, which also includes oestrogen hormones.
