Yacellais a contraceptive and is used to prevent pregnancy. Each tablet contains a small amount of two different female hormones, called ethinyl estradiol and drospirenone. Contraceptives that contain two hormones are called "combined" contraceptives. The hormones in the pill do not allow ovulation to occur. If there is no ovulation, there will be no egg that the sperm can fertilize and so pregnancy does not occur. Also, the hormones in the birth control pill make the mucus from your cervix (the lower part of your uterus) thicken and block the sperm from reaching the egg, like a security guard who doesn't let anything pass.

What is Yacella?

Yacella is a combined contraceptive pill. It contains two active ingredients called ethinyl estradiol and drospirenone, which are synthetic versions of estrogen and progesterone, respectively. Essentially, these additional hormones work by preventing ovulation from occurring (this means that no egg is released from the uterus for fertilization). A Yacella course is taken for 21 days.

How does it work?

The Yacella contraceptive pill works by stopping sperm from reaching the egg (a process known as fertilization).

The hormones in the pill do not allow ovulation to occur. If there is no ovulation, there will be no egg that the sperm can fertilize and so pregnancy does not occur. Also, the hormones in the birth control pill make the mucus from your cervix (the lower part of your uterus) thicken and block the sperm from reaching the egg, like a security guard who doesn't let anything pass.

What are the benefits of taking it?

Yacella is a contraceptive and is used to prevent pregnancy. Each tablet contains a small amount of two different female hormones, called drospirenone and ethinyl estradiol. Contraceptives that contain two hormones are called combined contraceptives.

How do I use it and its dosage?

No form of contraception has a 100% guaranteed success rate. However, if you take Yacella exactly as prescribed, it will be 99% effective.

In terms of contraception, 99% effectiveness means that of every 100 women who take a contraceptive method for a year, only one will become pregnant.

  • Take one Yacella pill once a day for 21 consecutive days.
  • You must take the pill at the same time every day.
  • Each pill is specifically marked with the corresponding day of the week it is to be taken.
  • You can take the pill with or without food.
  • Once you have taken Yacella for 21 consecutive days, stop taking it for the next 7 days.
  • After this 7-day abstention time, start the course again the next day.
  • If you forget to take a pill, take the missed one as soon as you remember.

If you are more than 12 hours late taking a forgotten pill, you should use additional protection, such as a condom, for the next 7 days.

Frequently Asked Questions

Yes, you can switch from another combined pill to Yacella without losing contraceptive protection. You should start Yacella the day after finishing your current pill pack, with no gap.

If you are switching from a progestogen-only pill (mini pill) to a combined pill, you may need to use additional contraception for 7 days. You should always follow a healthcare provider’s advice when changing your birth control method. Switching pills can sometimes lead to temporary changes in your bleeding pattern.

Yacella may be prescribed to women with PCOS to help regulate their menstrual cycle, reduce acne, and manage excess hair growth. The drospirenone component can help lower androgen levels, which are often elevated in PCOS.

It may also help prevent endometrial thickening, which can result from irregular periods. You should always speak to your healthcare provider or an online pharmacist before using any hormonal contraception to manage PCOS.

It may take 1–3 months for your body to adjust to the hormones that are in Yacella. Mild side effects such as nausea, spotting, or breast tenderness are common but usually temporary.

You might not have full contraceptive protection during the first 7 days of taking Yacella, so you should use additional protection, such as condoms, during this time. Some women report clearer skin and more regular periods after a few cycles.

There are certain medications that you cannot take, as they can reduce the effectiveness of Yacella, increasing the risk of pregnancy.

These include: some antibiotics, anti-epileptic drugs, HIV medications, and herbal supplements. Always check with a pharmacist before starting any new medication while taking Yacella. Use additional contraception if you are taking any medicines known to interfere with hormonal contraceptives.

Yacella can help regulate menstrual cycles and reduce irregular periods over time. The consistent hormone levels in Yacella promote more predictable monthly periods. Some women find that their periods become lighter, less painful, and more regular within the first few months of use.

Yacella is a prescription-only medication in the UK and cannot be purchased legally without a consultation. At Pharmacy Planet, you can complete a short online consultation, which is then reviewed by a UK-registered prescriber. Once approved, your order is delivered discreetly and quickly to your address.
