IUD / IUS

Intrauterine System – IUS/Coil

The IUS is a method of Long Acting Reversible contraception LARC. A small, T-shaped, progestogen-releasing, plastic device is put into the uterus.

Advantages

  • Over 99% effective.
  • It works for 5 years.

Disadvantages

  • May cause discomfort and cramping for the first few days.
  • An IUS does not protect you from sexually transmitted infections, so you will need to use condoms as well.
