Pros and Cons of the Mirena IUS

The Mirena IUS is a long-lasting, reversible form of contraception that works by releasing the hormone progestogen directly into the uterus. If you are considering having a Mirena intrauterine system fitted, then you should discuss both the advantages and the disadvantages with your doctor, who will be able to give you personalised advice.


Advantages


You can rely on the Mirena IUS for your birth control as it is one of the most effective forms of contraception. At the same time, the effect is completely reversible and fertility usually returns to normal very quickly after the IUS is removed. The Mirena IUS is also safe to use after having a child, even while you are still breastfeeding.


The Mirena IUS is also a very convenient form of contraception to use, since it can usually remain effective for between three and five years after it has been fitted. There is no need to remember to take a pill or to prepare in any way before having sex, although you should still consider using condoms as the Mirena IUS does not provide any protection against sexually transmitted infections.


As well as being an effective and convenient form of contraception, the Mirena IUS can also have some additional benefits because it can help to make periods lighter. It can therefore be a particularly good choice if you tend to experience heavy menstruation or cramping. Some women may choose to have the IUS fitted specifically in order to treat menstrual problems, rather than primarily as a contraceptive device.


Disadvantages


While the Mirena IUS can be a very effective and convenient form of birth control, there are also some potential disadvantages to consider before choosing this method. Some people can experience mild discomfort as the device is inserted, and there can be some side effects such as irregular menstruation and spotting between periods. Other potential problems can include infections and issues caused by the IUS slipping out of place, but these risks can be reduced by checking for signs of infection before the IUS is inserted and ensuring that it is put in place by an experienced doctor.
