Intrauterine device (or coil) – is one of the most effective methods to prevent unwanted pregnancy. Coil is a device of a small size inserted into the cavity of the uterus.

Implantation of intrauterine devices (known also as IUD) in the womb inhibits the progression of spermatozoa to the egg and complicates its fertilization. Even if fertilization has occurred, the IUD interferes with the attachment of the fertilized egg to the uterine wall.

Modern IUDs, approved in the USA, are divided into two types:

Non-hormonal IUDs

contain copper

Hormonal IUDs

contain Levonorgestrel hormone

Today, the following intrauterine contraceptive devices are most popular among American women:









Before buying contraceptive coil, the woman should consult a health care provider. Despite the same indications for use, each contraceptive has distinctive features.

Intrauterine devices intended for a long-term contraception should be inserted:


  • in a medical institution only;

  • after a preliminary medical examination.

Hormonal intrauterine devices can be inserted on any day of the menstrual cycle, but their effect develops only on the 7th day after the insertion. In the first week after installing the coil, the woman should use back-up birth control methods.

After the insertion of intrauterine system, periods become lighter or can be absent for a few months in most women. This undesirable effect does not require the cessation of the long-term hormonal contraception.

As a rule, side effects of the coils are associated with the hormone action and largely depend on the characteristics of the female body.

The most frequently adverse reactions are as follows:


  • headache;

  • breast pain;

  • menstrual spotting;

  • bacterial vaginosis.

In some cases, the IUD may cause infection of the genitals, the ovarian cysts, ectopic pregnancy.

If the woman feels pain in the abdomen, experiences dizziness, headaches, or vaginal bleeding for a long time after the coli implantation, she urgently needs to seek medical help.

Although the use of intrauterine contraceptive devices has many benefits, their use is limited.

Coils are not recommended for women with:

Uterine anomalies and pelvic infections

Acute liver disease

Vaginal bleeding with unclear etiology

Since the contraceptive effect is carried out locally, it is unlikely that the effectiveness of intrauterine devices can change under the influence of other medications.

High reliability contributes to the popularity of this contraception method.

IUDsWomen, who have limited or no access to contraceptives, can order intrauterine devices on affordable price on online drugstore.

Before to buy a coil, the woman may ask a doctor online whether this contraception method is contraindicated to her or not.

It is important to understand that intrauterine devices do not protect against sexually transmitted infections. Therefore, do not forget about the condom in the absence of the regular sexual partner.

To date, Skyla, Mirena, Paragard, and Liletta IUDs are the most effective and the safest way to prevent pregnancy among all available contraception methods.
