Getting your repeat pill just got simpler. Buy Logynon online.

Logynon is a combined contraceptive pill that contains two hormones (fancy word alert): ethinylestradiol and levonorgestrel. These two hormones work in the same way as oestrogen and progesterone in the body to stop you from getting pregnant.

Prescriptions posted promptly to your door. How does that sound? With an EveAdam subscription, you can buy Logynon online and we’ll deliver it to you as often as you need it. Start a consultation to get treatment suggestions from our clinician, and choose an option. They’ll then put together your prescription and our pharmacy will do the rest.

Your first package will be delivered to you in one working day by special courier (provided your prescription is approved before 4pm) and after that, every 3, 6, 9 or 12 months, depending on your preference.

No faff. No fuss.

How does Logynon work?

There are three ways in which Logynon gives you protection from pregnancy.

The two hormones in it stop the ovaries from releasing an egg during ovulation, and thicken the mucus in the neck of the womb, which makes it more difficult for sperm to reach an egg.

They also make the lining of the uterus thinner, which reduces the chances of a fertilised egg latching on to the uterine wall and growing.

The combined pill tends to make your periods lighter, regular and less sore, so there are additional benefits to taking it too.

So it’s an all-round multitasker.

What’s the difference between Logynon and Logynon ED?

Logynon is a 21 day-pill, whereas Logynon ED is a 28-day pill.

Both pills are made by Bayer, and both contain the same hormones, and work in the same way in the body. The only difference is that you take Logynon for 21 days, and then take a 7-day break from it. With Logynon ED, once you’ve finished the 21 day course, you take 7 inactive pills (so 28 pills in total, making it a 28-day pill).

Some women prefer to stay in the routine of taking a pill every day, rather than taking a 7-day break, just to reduce the risks of ever forgetting a pill. The extra 7 placebo pills that you get with Logynon ED help to provide this security.

What you need to know about Logynon

What is Logynon?

Logynon is a branded combined contraceptive pill that protects you from getting pregnant.

It’s known as a ‘triphasic’ pill, which sounds a bit like something out of a natural history programme, but it’s pretty simple. A triphasic pill is a pill that contains three different dosages of progesterone and oestrogen that you take for 21 days, followed by a 7-day break in which you take no pills.

The 21 active pills are three different colours, for each of the three dosages. Six are light brown (containing 30/50 micrograms of ethinylestradiol and levonorgestrel), five are white (containing 40/75 micrograms of ethinylestradiol and levonorgestrel) and 10 are ochre (that’s yellowy-mustard by the way), containing 30/125 micrograms of ethinylestradiol and levonorgestrel). So speaking plainly, different pills with different hormones in them.

As a triphasic pill, because it contains different amounts of hormones and mimics the body’s natural cycle very closely, it’s very important that Logynon pills are taken in the correct order.

How to take Logynon pills

Each pill in the strip has a day of the week marked next to it, and you should take each one on the day of the week that it corresponds with. Take one pill at the same time every day.

It’s best to take your first pill on the first day of your period, as this will give you immediate protection from pregnancy.

Start by taking pill number 1, and mark that day of the week beneath the heading, ‘I took my first pill on’ by piercing the small, foil disc that isn’t numbered. This is there to help remind you of the day you started your strip on.

Follow the direction of the arrows on the strip until you have taken all 21 pills. You can swallow each pill whole with water if you prefer to, but don’t chew the pills. Once you’ve finished the strip, have 7 pill-free days. So if you take the final pill of a strip on a Friday, take the first pill of the next pack on the Saturday of the following week.

A couple of days after taking the last pill from the strip, you should get a withdrawal bleed like a period. You may still be experiencing this bleed by the time you start your next strip of pills; this is absolutely fine and nothing to worry about. It’s important that you start your new strip on time.

So long as you’ve taken your pills correctly and start your next strip of pills when you should, you don’t need to use any additional contraception during your 7 pill-free days.

Provided that you take Logynon correctly, you’ll always start a new strip on the same day of the week.

Logynon vs Microgynon: what’s the difference?

Logynon and Microgynon 30 are both combined hormonal contraceptive pills, and both pills contain the same two hormones, ethinylestradiol and levonorgestrel. They also work in the same way in the body, and are even made by the same company: Bayer.

The difference is that Logynon is a triphasic pill, whereas Microgynon 30 is what we call a monophasic pill, which just means that each pill has the same amount of hormones in it.

Like Logynon ED, which is the 28-day pill alternative to Logynon, there is also a 28-day option for Microgynon, Microgynon ED. So you can choose to take 21 active pills and then 7 placebo or non-active pills, rather than taking a 7-day pill-free break after 21 days.

In terms of which pill is best for you, it depends on how your body reacts to a higher, lower or a more mixed amount of hormones. Our prescriber can help to guide you on this during your consultation, taking your medical background and any symptoms or side effects you’ve experienced previously with combined pills into account.
