Buy Katya contraceptive pills online

Katya is a type of combined contraceptive pill containing synthetic versions of the two natural female sex hormones oestrogen and progesterone: 30mg of ethinylestradiol and 75mg of gestodene. These active ingredients work to prevent pregnancy by stopping the ovaries from releasing any eggs, with up to 99% effectiveness when taken correctly.


How Katya works to prevent pregnancy

Katya contains two female hormones to help protect against pregnancy: gestodene and ethinylestradiol. These active substances work as a contraceptive by preventing your ovaries from releasing an egg every month. It also thickens the mucus in the cervix (the neck of the womb) so it’s harder for sperm to reach an egg, and thins the lining of the womb so there’s less chance of a fertilised egg being able to implant itself into the womb and start growing. This means there are three preventative measures in place, making it extremely unlikely for you to fall pregnant. 



You should take one pill each day at the same time each day, with or without food. Each strip contains 21 tablets, all labelled with days of the week to make it easier for you to keep track. After you’ve finished the strip of 21 tablets, you should have a 7-day break where you don’t take any tablets at all. During this break, you will experience a withdrawal bleed similar to a period. If you’re still bleeding when it’s time to start your next strip, you should still start the strip on time after the 7-day break.


What if I miss a pill? 

If you’re less than 12 hours late in taking a pill, the protection from pregnancy won’t be reduced. If you’re more than 12 hours late, you will have to use a barrier method of contraception. The more pills you miss, the greater your risk of becoming pregnant. Follow the advice below depending on where you’re up to in your strip:


More than one tablet forgotten:

Contact your doctor or Chemist4U pharmacist.


One pill forgotten in week 1:

Take the forgotten pill as soon as you remember, even if that means taking two in one day. Continue taking your pills at the usual time and use a barrier method of contraception for the next 7 days. If you have had sex in the week before forgetting your pill, you could be pregnant - contact your doctor if this is the case.


One pill forgotten in week 2: 

Take the forgotten pill as soon as you remember, even if that means taking two in one day. Continue taking your pills at the usual time; you are still protected from pregnancy and don’t need to use extra contraception.


One tablet forgotten in week 3:

Option 1: Take the forgotten pill as soon as you remember, even if that means taking two in one day. Continue taking your pills at the usual time, but instead of taking the 7-day break at the end of the strip, skip this break and go straight to your next strip.

Option 2: Stop the strip immediately and begin the 7-day break, which will include the day you forgot your pill. After that, start your next strip as normal.

If you are sick or have severe diarrhoea within 3-4 hours of taking Katya, your body may not have absorbed the active substances in the pill. If you can’t manage to take a spare pill within 12 hours of vomiting or having severe diarrhoea, you should follow the instructions on what to do in the event of a missed pill.


Starting Katya

The best way to start Katya for the first time is by taking your first pill on the first day of your next period. By doing this, you will be protected from pregnancy straight away. You can start taking Katya at any point in your cycle, but you will need to use a barrier method of contraception for the first 7 days of pill usage.


Coming off Katya

You can safely stop taking Katya at any time, but you will no longer be protected from pregnancy. The best time to stop taking Katya is after you’ve finished a full strip - this way, your cycle should continue as normal. If you want to become pregnant, stop taking Katya and wait for your next period before trying to become pregnant - this will make it easier to calculate your expected delivery date.


Side effects

Like all medicines, there is a possibility that you may experience side effects when taking Katya. These should usually be mild, and not everyone will experience them. If you experience any signs of severe side effects, such as an allergic reaction or a blood clot, seek medical attention immediately. Information regarding the symptoms of these rare but severe side effects can be found in the patient information leaflet. 

Common side effects that may affect up to 1 in 10 people include: 

  • Headaches
  • Nervousness
  • Poor tolerance of contact lenses
  • Visual disturbances
  • Nausea
  • Acne
  • Migraine
  • Weight gain
  • Fluid retention
  • Bleeding or spotting between periods
  • Less or no periods
  • Sore breasts
  • Low sex drive
  • Depressive moods
  • Irritability

For more information on uncommon, rare or very rare side effects, refer to the patient information leaflet. 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.


Blood clots

Using a combined contraceptive pill like Katya can increase your risk of developing a blood clot. Whilst still rare, the risk is highest during the first year of taking the pill, and you should be aware of the symptoms. Seek emergency medical attention if you experience any of the following symptoms: 

  • Throbbing or cramping pain, swelling, redness and warmth in your leg or arm
  • Sudden breathlessness, sharp chest pain and a cough or coughing up blood

For further information on the link between the combined contraceptive pill and blood clots, as well as more symptoms to look out for, refer to the patient information leaflet.


Breast cancer

Breast cancer has been found slightly more often in women who take a contraceptive pill compared to women who don’t. Once you stop taking the pill, the risk gradually decreases and 10 years after stopping the pill the risk will be the same as someone who has never taken a contraceptive pill. Breast cancer is still rare for anyone under the age of 40, even in women who take the pill.

Frequently Asked Questions

Can the pill be used to treat acne?

Combined contraceptive pills are not specific treatments for acne.

However, some doctors will prescribe a combined contraceptive pill to women who suffer from hormonal acne, as there does seem to be a beneficial effect.

This is only the case with combined contraceptive pills, not progestogen-only mini-pills.

It can take around 2-3 months of taking the pill before you may notice any effect on your acne.

Do I need a prescription for this medication?

You do need a prescription for this medication in the UK.
