General information

What is T-Safe?

T-Safe is a reliable copper IUD of high quality, ideal for women who choose hormone-free contraception. The natural cycle is maintained and you can have carefree sex. The T-Safe IUD is T-shaped and made of plastic and copper. T-Safe also works as emergency contraception if inserted within five days of unsafe sex.

How does a copper IUD work?

A copper IUD gradually releases a little copper in the womb. Copper paralyses the sperm cells and makes them inactive so that fertilisation cannot take place. Copper also prevents an egg cell from implanting in the uterine wall. A copper IUD works immediately after placement and is a very reliable form of contraception. T-Safe is the most effective copper IUD and can remain in place for up to 10 years. Of course, you can also use the IUD for a shorter period of time. A copper IUD also works as a morning-after IUD if it is inserted within 5 days after unsafe sex. The IUD causes the endometrial lining to change so that any fertilised egg cannot implant in the uterine wall.

How reliable is the T-Safe copper IUD?

The T-Safe copper IUD is a very reliable form of contraception and you do not have to think about contraception every day. Out of every 1,000 women who use a copper IUD, no more than 2 become pregnant each year. T-Safe is the most commonly used copper IUD in the Netherlands and meets the highest quality requirements.

How long does the T-Safe copper IUD last?

A T-Safe copper IUD is effective for no less than 10 years. Most other copper IUDs, such as the Multi-Safe, are effective for 5 years.

    - You don't have to think about contraception every day.
    - The T-Safe copper IUD works for up to 10 years.
    - It is safe to use T-Safe when breastfeeding.

What are the disadvantages of a T-Safe copper IUD?

In the first three months after insertion, your period may be different from normal. Most women experience little to no discomfort from the copper IUD, but others may have side effects, such as:
    - heavy, prolonged and/or irregular menstruation.
    - (sometimes severe) abdominal cramps.
    - Intermittent blood loss.

    After about three months, your body gets used to the IUD and the natural cycle restores. A small number of women continue to experience slightly more blood loss during their periods. Copper IUDs are less suitable for women who naturally have heavy periods and suffer from this.

How is a T-Safe copper IUD implanted?

Placing the copper IUD is simple and goes quite quickly. The IUD is usually inserted during or just after menstruation to ensure that you are not pregnant and because it is a little easier to insert. Before insertion, your healthcare professional will check the position of your uterus. A speculum is then inserted into the vagina to get a good look at the cervix. To know whether the uterus is suitable for the IUD, the length of the uterus is measured with a probe (thin rod). The doctor/ midwife then inserts the IUD into the uterus via the insertion sleeve. Finally, the wires are cut to the correct length. The actual insertion takes about 5 minutes. Your healthcare professional will guide you through this process.

Is the insertion of a copper IUD painful?

The installation of a T-Safe copper IUD can be unpleasant and sometimes even painful for some women. Women who have already had a child are generally less affected, if at all. You can take two Aleve Feminax 275 or an Ibuprofen 400 the evening before the placement and the same dose again an hour before the placement. If necessary, you can then take one tablet of Aleve Feminax or Ibuprofen three times a day for a few days. This helps relax the uterus and the muscles around it, making the insertion of the coil and any cramps afterwards less painful. A local anaesthetic is sometimes also possible. Discuss this in advance with your healthcare professional.

How is the copper IUD removed?

Removing the T-Safe copper IUD is very simple. Your healthcare professional pulls the wires and the IUD is removed almost painlessly. It is possible to have a new IUD placed immediately after removal.

Where can I have the T-Safe IUD placed?

For placing of the T-Safe copper IUD You can contact your family doctor, midwife or gynaecologist. You can also have an IUD fitted at various independent clinics. At you will find an overview of midwives and independent clinics in your area.

Can you go under an MRI scan with a copper IUD?

Various studies have shown that 3.0 Tesla MRI procedures are safe for patients with copper IUD. Please inform the radiologist in advance that you have a copper IUD.

When should you not use a copper IUD?

You cannot use a copper IUD in case of:
    - pregnancy
    - unexplained vaginal bleeding
    - an active inflammation of the genital system
    - an abnormality of the uterus
    - malignant diseases of the genital system
    - Wilson's disease
    - a copper allergy

Does T-Safe protect against STIs?

No, T-Safe does not protect against sexually transmitted infections (STIs), including HIV/AIDS. For protection against STIs you should use a condom.

Who is T-Safe suitable for?

T-Safe is ideal for women who prefer hormone-free contraception. You keep your natural cycle and choose a reliable form of contraception. The copper IUD is suitable for almost all women of childbearing age. For very young women (e.g. 13-14 years), we recommend consulting a health professional first. For example, T-Safe is suitable for:
    - Women who want to maintain their natural cycle
    - Women who cannot tolerate hormones or who are not allowed hormones
    - Women who do not want a permanent solution in the form of sterilisation, but want ten years of reliable contraception
    - Women who do not want to think about contraception every day
    - Women with irregular, busy lives
    - Women with limited financial resources
