Katya

Katya is a combined oral contraceptive pill which you can take to help prevent pregnancy.

When used as instructed, Katya is 99% effective. This is because there are 2 types of hormone in each Katya pill. One is a type of oestrogen and the other is similar to progesterone. You produce both types naturally, and when you take them daily it can prevent pregnancy.

For Katya to work, you take 1 pill for 21 days in a row and then have a 7 day break, where you take no pills. However, you are protected for all 28 days as long as you do not miss any pills.

Take Katya as directed by your doctor or pharmacist. Normally, they will advise you to follow these steps:

1. Take 1 pill every day for 21 days at the same time each day, and swallow it with some water if needed. You can take the pill with or without food.
2. Take the pill marked with the current day of the week and follow the arrows for the next day pill.
3. After 21 days you have a 7 day break where you take no pills for 7 days.
4. You may have a withdrawal bleed (period-like bleed) that usually starts on day 2 or day 3 of the 7 day break.
5. On the 8th day after your last Katya pill you should start the next strip of pills, and this will be on the same day of the month as the first strip. Do this even if your withdrawal bleed has not stopped, to remain protected.

For further information refer to the patient information leaflet.

Katya is a combined oral contraceptive pill that has 2 female sex hormones. These are ethyinylestrodiol (an oestrogen) and gestodene (a progestogen). Together these hormones work to:

• prevent the ovaries from releasing an egg (ovulation) - reducing the chance of pregnancy
• thicken cervical mucus - making it difficult for sperm to reach the egg
• thin the lining of the womb - making it difficult for an egg to implant

Other benefits of using combined oral contraceptives include keeping acne under control.

When used perfectly and as instructed, Katya is 99% effective. Katya is highly effective at protecting against pregnancy. If you start taking Katya during the first 5 days of your period it is effective as soon as you start taking it.

If started at a different time in the menstrual cycle you should use other additional methods of contraception (e.g. condoms). This should be for the first 7 days of taking Katya. See our guide explaining the effectiveness of the pill.
