What is Logynon?

Logynon is a combined oral hormonal contraceptive - colloquially known as “the pill.” Contraceptives stop you getting pregnant. There are two types of contraceptive - barrier methods, such as condoms and vaginal films, and hormonal methods, such as oral pills, injections, implants and patches.

Logynon is a pill that you swallow once a day. When taken correctly, oral contraceptive pills are one of the most reliable methods of hormonal contraception, and can be up to 99% effective at preventing pregnancy.

Oral contraceptives are prescription medication. They are available from your pharmacist or doctor, with a valid prescription. Alternatively, we are able to prescribe oral contraceptives such as Logynon to you online following a brief consultation. Contact us to find out more.

The two active ingredients in Logynon are ethinylestradiol and levonorgestrel. If you need more information on Logynon, consult the patient information leaflet.

How it works

Just like other combined oral contraceptive pills, Logynon works by releasing two female sex hormones into your bloodstream - progesterone and oestrogen. These hormones stop your body from releasing an egg every month (ovulation,) thicken cervical mucus to make it more difficult for sperm to reach the egg, and thin the lining of your womb to prevent an egg implanting itself.

Logynon can take up to 7 days to begin working, depending on where you are in your menstrual cycle when you begin taking it. You should use additional contraceptive methods, such as condoms, during these 7 days, as you may not yet be protected from pregnancy by Logynon.

Before you take it

You should not take Logynon if you are allergic to the active ingredients ethinylestradiol or levonorgestrel, or any of the other inactive ingredients contained within the medicine. Speak with your doctor, who will be able to recommend an alternative, more suitable method of contraception.

Logynon will not protect you against sexual health problems, including sexually transmitted diseases. No oral contraceptive can do this. If you are concerned about contracting a sexually transmitted disease, you should use a condom.

Logynon contains lactose and sucralose. If you are allergic to lactose or sucralose, or any other type of sugar, you should find an alternative method of contraception. Your doctor will be able to recommend suitable alternatives.

You should be aware that if you take emergency contraception such as the morning after pill, it may make Logynon less effective. You must use a barrier method of contraception for 14 days from the day you take emergency contraception before Logynon becomes effective again.

Your doctor may wish to examine you more thoroughly while you are taking this medication, to check for your risk of developing breast or cervical cancer. They may wish to conduct a cervical smear test, or examine your breasts. You should monitor your own breasts for any abnormalities, and report them to your doctor if and when you find them.

Do not take other combined contraceptives at the same time as Logynon. One contraceptive pill is enough to prevent you from becoming pregnant - you do not need to use more than one. It’s safe, however, to use barrier methods of contraception such as condoms alongside Logynon.

You may be at an increased risk of developing a blood clot or thrombosis when taking Logynon. Blood clots can be fatal in certain cases. This risk is very small, but if you have experienced blood clotting or thrombosis before, or you have a family history of blood clotting, you should take advice from your doctor before using Logynon.

Logynon is unsuitable for pregnant or breastfeeding women. It will not terminate a pregnancy.

A combined pill such as Logynon won’t affect your ability to drive or operate heavy machinery.

Logynon may also be prescribed for women who have particularly heavy periods, as it can make periods lighter or eliminate them entirely.

Do not take Logynon if any of the following applies to you:

  • If you have, or have ever had a blood clot or any type of thrombosis, or if you have a disorder or condition affecting your blood clotting
  • If you need an operation, or you know you will be off your feet for a long time
  • If you are pregnant or breastfeeding
  • If you have experienced angina
  • If you have ever had a heart attack or stroke
  • If you have severe diabetes with blood vessel damage
  • If you have heart or liver disease

You should be aware that taking the following medications alongside Logynon can cause drug interactions:

  • Medicines used to treat epilepsy - carbamazepine, gabapentin, pregabalin
  • Medications used to treat HIV - ritonavir, efavirenz
  • Antifungals such as griseofulvin
  • Antibiotics
  • Modafinil for narcolepsy (can make Logynon less effective)
  • Sedatives
  • St John’s Wort for depression

This is not an exhaustive list of warnings and interactions. For a full list, you should speak with your doctor or consult the patient information leaflet.

Dosage Instructions

You should always take Logynon exactly as your doctor or pharmacist has prescribed. Never exceed the stated dose. If you are in any way unsure of how to take Logynon, speak with your doctor or pharmacist.

You should make sure you are not pregnant before taking Logynon. If you are in any doubt, or have recently missed a period, take a pregnancy test.

Logynon comes as a pack of 21 pills. Each pack is designed to be taken over 21 days. Each pill is marked with a day of the week. Take one pill every day for 21 days, then have a 7 day period where you do not take any pills. During this time you may experience a period-like bleed. After the 7 day period, start a new pack.

If you are taking this pill properly, you should start a new pack on the same day every 4 weeks. During the 7 day break you will not need any additional contraception, providing you have taken all of your pills correctly, and you start your new pack on time.

If you are a new Logynon user, you should start taking it on the first day of your next period. If you do this, you will be protected from pregnancy immediately.

Swallow each pill whole with water. Do not crush, suck or chew on them.

Store your Logynon pills out of the reach of children and pets, in cool, dry place free from moisture and heat. Do not use Logynon pills after the expiry date on the pack.

Common Side Effects of Logynon

Like all medicines, Logynon may cause side effects. These are typically not serious in nature and should go away by themselves within a few months. However, if they concern you, or are persistent, speak with your doctor. Common side effects include:

  • Nausea
  • Vomiting
  • Weight gain
  • Tender breasts
  • Headaches
  • Depression

Logynon can also cause more serious, less common side effects. These are unusual, but if you experience them you must go to your doctor. They can include:

  • Abdominal pain
  • Fluid retention
  • Migraine
  • Loss of interest in sex
  • High blood pressure
  • Skin rash
  • Vaginal discharge

Logynon may also cause an allergic reaction. This is very rare, but an allergic reaction is an emergency, so if you experience this you must seek medical advice immediately. Symptoms of an allergic reaction include:

  • Hives
  • Trouble breathing or speaking
  • Wheezing
  • Tightness in the chest or throat
  • Skin rash, including itchiness, swelling, blistering or peeling

This is not an exhaustive list of symptoms or warnings. You should consult the patient information leaflet for a full list.

Frequently Asked Questions (FAQs)

What happens if I become pregnant?

When taken correctly, Logynon is up to 99% effective at preventing pregnancy. Most unwanted pregnancies that occur while taking Logynon are as a result of a dosing mistake - taking tablets at the wrong times, or missing tablets. If you discover you are pregnant while taking Logynon, stop taking it and visit your doctor or local family planning clinic.

What happens if I vomit or have diarrhoea?

Logynon is absorbed into the bloodstream through the lining of the stomach. If you vomit or have diarrhoea within 2 hours of taking a Logynon pill, it may not have been fully absorbed into the bloodstream, and it may not be as effective. If you experience vomiting or diarrhoea within 2 hours of taking your pill, take another pill once you feel well enough to do so.

What happens if I miss a dose?

If you miss your dose of Logynon, take it as soon as you remember if it has been less than 24 hours since you should have taken it. You will still be protected against pregnancy. If it has been longer than 24 hours, skip the missed pill and continue taking as normal the next day. You must use additional contraception for the next 7 days to prevent pregnancy.

What happens if I take too much?

An overdose of Logynon is unlikely to harm you significantly, but may cause symptoms such as sickness, vomiting or vaginal bleeding. If you experience this, go to your doctor.
