Description for Triadene Tablets

Phasic 21-day contraceptive pills, like Triadene, contain a combination of the hormones oestrogens and progestogens. They help to make it harder for the sperm to penetrate the womb and to reduce the chance of a fertilised egg implanting in the womb. If taken correctly they are over 99% successful at preventing pregnancy.

Product Information

  • Age: 18 years +

    Maximum per order: 2

  • Pregnancy: Not suitable

    Breastfeeding: Not suitable

Triadene is an oral contraceptive. It is a triphasic combined pill, manufactured by Bayer. When used correctly, it will provide near 100% protection against pregnancy. Its two active ingredients, gestodene and ethinylestradiol, prevent ovulation from occurring during the menstrual cycle. Triadene is 'triphasic' in that it varies the amount of gestodene in one dose, depending on the week in the cycle. This more closely mimics the natural hormonal cycle, which reduces some of the side effects associated with many other oral contraceptives.

Pregnancy occurs when an egg released from the ovaries is fertilised by sperm. In a normal menstrual cycle, the ovaries release one egg each month - this is the process of ovulation. This process is controlled by the female sex hormones progesterone and oestrogen. Triadene contains two synthetic hormones, gestodene and ethinylestradiol, which imitate these two natural hormones. They control the levels of each hormone in such a way that prevents an egg from being released. The Pill also makes it more difficult for sperm to reach the uterus, by thickening the fluid that is in the cervix.

During a regular menstrual cycle, the endometrium (the wall of the uterus) builds up in preparation for a fertilised egg. Triadene reduces the extent of this buildup, making it less likely that a fertilised egg will develop into an embryo. As a further result, periods become lighter. The biphasic course of norethisterone in Triadene reduces side effects by more closely imitating the natural hormonal cycle.

There are 21 Triadene pills in a pack. Once you have finished a pack, you will stop taking the pill for seven days. During this time you will have a normal bleed. Once seven days have passed, begin your next cycle of treatment.

Non-Medicinal Contraception Alternatives

  • Female Condoms- Not only do they prevent pregnancy they also prevent STIs. There is currently only one brand available in the UK, called Femidom. Shown to be 95% effective. 
  • Male Condoms- Prevent pregnancy and also prevent STIs. Shown to be 98% effective. 
*Prescription medicines are supplied subject to a medical consultation at the discretion of a doctor.

If possible, begin taking Triadene on the first day of your period. Take one pill at a similar time each day, in the indicated order.

For the first six days, you will take beige tablets. For the next five days you will take brown tables. For the final ten days, you will take white tablets.

There are 21 Triadene pills in a pack. Once you have finished a pack, you will stop taking the pill for seven days. During this time you will have a normal bleed. Once seven days have passed, begin your next cycle of treatment.

If you forget to take a dose, take it as soon as you remember, even if it is nearly time for your next pill. If you have missed one day, you should still be protected from pregnancy. If you miss multiple days, you are advised to use additional contraception for the following seven days.

Not everyone will experience side effects when they take Triadene, however if you do they may include:

Nausea, weight gain, headaches, stomach pain, mood swings, breast pain

If you are concerned about these effects, or if the product affects you in any other way, stop using it and talk to your doctor or pharmacist.

The active ingredients contained in Triadene are:

Beige tablets - 50mcg gestodene, 30mcg ethinylestradiol

Brown tablets - 70mcg gestodene, 40mcg ethinylestradiol

White tablets - 100mcg gestodene, 30mcg ethinylestradiol

Triadene also contains the following inactive ingredients to make up the complete product:

Lactose, maize starch, povidone 700 000, calcium disodium edetate, magnesium stearate (E572), sucrose, macrogol 6000, calcium carbonate (E170), talc, montan glycol wax, titanium dioxide (E171), ferric oxide pigment (brown and yellow) (E172), glycerol (E422).

Reading the following warnings carefully will help to ensure you are selecting an appropriate product.

Triadene is unsuitable for you if you have:

  • An allergy to any of the ingredients of Triadene
  • A history of breast cancer
  • A blood clotting disorder
  • Ever had a blood clot
  • A history of heart attack or stroke
  • Angina pectoris
  • Very high blood pressure
  • High levels of lipids in the blood
  • Impaired liver function
  • Severe migraines

You may be advised not to take Triadene if you suffer from any of the following conditions:

  • Crohn's disease or chronic inflammatory bowel disease
  • Kidney failure
  • Sickle-cell anaemia
  • Systemic lupus erythematosus
  • Pancreatitis
  • An inflammation of veins under the skin
  • Varicose veins
  • Diabetes
  • Porphyria
  • A family history of blood clots or circulation problems
  • Obesity
  • Migraines

Do not use Triadene if you have breast cancer, or if you have had it before. Long-term use of hormonal contraceptives may slightly increase your chance of developing breast cancer. Once you have stopped using the Pill for at least 10 years, your risk levels will come back down. Women who are elderly and/or overweight are more vulnerable to breast cancer. Take care using Triadene if a close relative has suffered from breast cancer before. Check your breasts and nipples regularly for any changes or lumps. If you notice anything abnormal, visit your doctor as soon as you can.

You may be more susceptible to blood clots while taking Triadene, especially during the first year of use. Talk to your GP before having any operation while taking the Pill. You may need to stop using Triadene in advance of the operation to avoid the increased risk of a blood clot. You are also at a heightened risk of developing a blood clot if you:

  • Smoke
  • Are obese
  • Have a family history of blood clots
  • Do not exercise regularly
  • Have had a miscarriage in the past
  • Have recently given birth

Triadene may increase your chance of developing cervical cancer. For this reason, you should have regular smear tests while taking the Pill.

If you require any blood test, inform your doctor of which medicines you are taking - Triadene may alter the results of some blood tests.

The following medicines may impact the effectiveness of Triadene:

  • Epilepsy medicines (e.g. phenytoin, carbamazepine)
  • HIV medicines
  • Hepatitis C medicines
  • Some antibiotics
  • Barbiturates
  • St John's Wort
  • Griseofulvin

Triadene may also impact the effectiveness of some medicines. Please read all packaging and the Product Information Leaflet before taking any new medicine and inform your doctor of medicines you are taking or intend to take.

Frequently Asked Questions

  • What is Triadene used for?

    • Contraception.
    • Treatment of heavypainful or irregular periods.
  • How does Triadene work?

    Triadene tablets are a hormonal contraception known as 'the pill' or combined oral contraceptive pill. Triadene tablets contain the active ingredients ethinylestradiol and gestodene and are synthetic versions of the female sex hormones, oestrogen and progesterone. Ethinylestradiol is a synthetic form of oestrogen and gestodene is a synthetic form of progesterone.

    Combined oral contraceptives like Triadene override a woman’s normal menstrual cycle. In a typical cycle, levels of sex hormones change throughout the month. They cause the ovaries to release an egg and prepare the womb’s lining for a possible pregnancy. If the egg has not been fertilised by the cycle’s end, the hormone levels fall and the womb’s lining is shed as a monthly period.

    The hormones contained the Triadene fool a woman’s body into thinking that it has already ovulated. This prevents an egg from being released by the ovaries.

    The hormones also increase the thickness of the cervix’s natural mucus, making it more difficult for sperm to cross from the vagina and fertilize an egg. They also alter the quality of the womb lining, making implantation less likely.

  • How do I take Triadene?

    Triadene is a triphasic pill. This means that each 21-day pack contains three kinds of tablets, each with a slightly different dose of hormones. The six beige tablets have 30 micrograms ethinylestradiol and 50 micrograms gestodene, the brown tablets have 40 micrograms ethinylestradiol and 70 micrograms gestodene, and the ten white tablets hav 30 micrograms ethinylestradiol and 100 micrograms gestodene.

    Triadene tablets must be taken in order, starting with the beige tablet marked 'start'. One tablet must be taken every day for 21 days, then there is a seven-day break. During the break, your hormonal levels drop, which results in withdrawal bleeding similar to a normal period. You will start the next pack after the seven pill-free days have ended, even if you are still bleeding.

    In your pill-free week you will still be protected against pregnancy provided you took all the pills correctly, you start the next packet on time and nothing else occurred that could make the pill less effective (e.g. vomiting, taking certain medicines, diarrhoea).

    You should try to take your pill at the same time every day. This will help you set a schedule for taking it and make it less likely you will miss a pill. Swallow each tablet with a drink; you can take it with or without food.

  • When should I start taking Triadene?

    If possible, begin taking Triadene on the first day of your period. If you begin taking the Pill in the first five days of your cycle, you will be immediately protected from pregnancy. If you begin later in your cycle, you will need to abstain from sex or use alternative contraception for the first seven days of taking Triadene.

    If you have a menstrual cycle of less than 24 days, you may need to use alternative contraception for your first seven days regardless of when you start.

    If you have just given birth, begin taking Triadene on day 21 following the birth. If you begin taking the Pill later than this, you will not be immediately protected against another pregnancy.

    Begin taking Triadene immediately following an abortion or miscarriage. If more than seven days have passed, you will need to use additional contraception for your first seven days of using the Pill.

  • What do I do if I miss a pill?

    Take any missed pills as soon as you remember. A pill is considered ‘missed’ if it is taken 24 hours or more late. See the instructions below.

    One missed pill

    If you miss ONE pill, or start your new pack a day late, you should take the pill you missed as soon as possible, even if you need to take two pills at the same time. Take the rest of the pack as normal. You will be protected against pregnancy and won't need additional contraception.

    Two or more missed pills

    If you forget to take TWO pills or more, or start your new pack two or more days late, you won't be protected against pregnancy. You should abstain from sex, or use a barrier method of contraception, e.g. condoms, for the next seven days. Take the last pill you missed as soon as possible, even if this means taking two pills at one time. Leave out the other missed ones. Then take  your pills, one every day, as usual. If there are fewer than seven pills left in your pack after your last missed pill, finish the pack and then start a new pack straight away without the 7-day break.

    If there are seven or more pills left in your pack after your missed pill, finish the pack and have your seven day break as usual before starting the next pack.

    You may need emergency contraception f you had unprotected sex in the seven days before you missed pills. Ask your doctor or pharmacist for advice.

    You can get additional advice about any of this information from your doctor, pharmacist or local family planning clinic.

  • What if I have vomiting or diarrhoea?

    • If you have vomited within two hours of taking a pill, it may not have fully absorbed into your bloodstream. Take another pill as soon as you can and continue to your next pill at the usual time. You should still be protected from pregnancy. However, if you continue to vomit for more than 24 hours, this may make your dosage less effective. You should keep taking your pill at the usual time, but treat each day that you vomited as if you had missed a pill. See the instructions under "what do I do if I miss a pill" above.
    • If you have severe diarrhoea for more than 24 hours, this may also decrease the pill’s effectiveness. You should keep taking your pill at the usual time, but treat each day with severe diarrhoea as if you had forgotten a pill and follow the instructions under "what do I do if I miss a pill.”
  • How effective is Triadene?

    If taken properly, Triadene is up to 99% effective in pregnancy preventions.

  • What are combined Pills?

    Triadene pills combine synthetic versions of oestrogen and progestogen—a woman’s natural hormones. They alter processes the monthly cycle to prevent pregnancy.

  • What are the risks?

    Combined pills can cause your blood pressure to increase. Be sure to check your BP regularly.

    Birth control pills have been linked to a slight increased risk of blood clots and breast cancer.

    Triadene pills do not provide protection against sexually transmitted diseases.

  • Is Triadene available for next-day delivery?
