What is the Gedarel contraceptive pill?

The combined pill Gedarel is ‘combined’ because it’s got two hormones in it: man-made versions of progesterone and oestrogen. These do a bit of work in the body to change your menstrual cycle slightly.

How? Here’s the super-quick explanation. The combined pill: stops you from ovulating (ovulation is the part where your ovary releases an egg. No egg, no fertilisation, no pregnancy); makes your cervical fluid thicker (so sperm can’t breeze through to an egg); and it makes it harder for any unlikely fertilised eggs to implant by changing the wall of the uterus.

How effective is Gedarel?

Gedarel effectiveness is the same as the combined pill in general: over 99%, so pretty good odds. We know, technically if it’s over ‘over 99%’ this should mean 100%, but really it’s somewhere between. For every 100 women who take the combined pill – exactly according to the instructions – over a period of one year, less than one will get unexpectedly pregnant.[1]

But people make mistakes. It’s quite common to miss a pill or be late taking it. So there’s a typical use rate of effectiveness for the pill too: about 91%. So out of 100 women using it typically, over one year, nine will get pregnant.

The best way to make sure you don’t get pregnant when taking Gedarel is to do it as correctly as you can. Take it at the same time on the days you should, and follow the instructions for advice if you make a mistake.

What’s the difference between Gedarel 20 and 30?

Oestrogen load. Gedarel 20 has 20 micrograms of oestrogen hormone (ethinylestradiol if you want to get specific) and Gedarel 30 has – you guessed it – 30 micrograms.

Why do they have two doses? Well, if you’ve taken Gedarel 30 before and had mild oestrogenic side effects (water retention, fuller breasts, nausea) you might be better on a slightly lower dose of oestrogen. That’s where Gedarel 20 comes in. On the other hand, if you take Gedarel 20 and get very mild progestogenic side effects (infrequent periods, dry vagina, low sex drive) you might be better with a slightly higher oestogren dose (Gedarel 30) to help cancel these out.

In short, settling on the right pill is a delicate balancing act. Having different doses of Gedarel helps to narrow down the choices a little better.

How to take the Gedarel pill

It’s vital that you take Gedarel as instructed by your prescribing clinician. Not doing so will likely lead to a reduction in its effectiveness and increase the risk of becoming pregnant.

Gedarel should be taken at the same time every day for 21 straight days at the start of your period (the first day of bleeding). This provides full protection against pregnancy from the start of treatment.

If you start taking Gedarel on any other day, you will need to use a barrier contraceptive for at least seven days.

If you have been taking a different combined contraceptive pill up until the day you switch to Gedarel, you should carry on taking the new course as a continuation. If you’re switching from the mini pill, you’ll need to use a barrier contraceptive for seven days to remain protected.

At the end of your 21 days of taking it, you’ll take a seven day break before starting the next strip. Gedarel withdrawal bleeding will normally start during your break.

The days of the week are marked on the blister pack so that you can keep track of what you have taken. Tablets should be swallowed whole with water.

Other combined contraceptives use different synthetic versions of progesterone. Finding which one is right for you might take some experimentation.
