IUS vs IUD – Know the Differences  

 

The IUD and IUS can cause confusion for obvious reasons. Not only are they so similar in name, but they are both comparable forms of contraception. The IUD stands for intrauterine device whilst the IUS stands for intrauterine system. For further information regarding thing two forms of long-term contraception, you can read below.

 

The similarities with both these forms of contraception is the size and shape; the IUD and the IUS are T-shaped devices that are measured and inserted into the vagina by a medical professional to stop unwanted pregnancy. The key difference is HOW they prevent pregnancy:

 

1.       IUS releases the hormone progestogen to prevent pregnancy.

2.       IUD is made of copper, which is released to prevent pregnancy.

 

What is an intrauterine device (IUD)?

The IUD may also be referred to as 'the coil' and tends to be the more popular out of the two devices. It is classed as a long-acting reversible contraceptive (LARC) – which you can read more about here (LINK) that is inserted into your vagina where it stays until it needs to be replaced, you wish to fall pregnant or you would like to change contraceptive method.

 

Some IUDs contain copper whilst others are made from plastic.

It is a T-shaped device that fits into the palm of your hand.

It lasts for 5-10 years, but can be taken out sooner if you wish.

It works immediately and can be inserted at any point in the month.

It doesn't protect against sexually transmitted infections (STIs).

 

What is an intrauterine system (IUS)?

The IUS is occasionally referred to as 'the coil' but this is generally reserved for the IUD. It is classed as a long-acting reversible contraceptive (LARC) that is inserted into your vagina where it stays until it needs to be replaced, you wish to fall pregnant or you would like to change contraceptive method.

 

IUS is a T-shaped or spherical shaped device that fits into the palm of your hand.

It is made from plastic and releases progestogen.

It lasts for 3-5 years, but can be taken out sooner if you wish.

It works immediately and can be inserted at any point in the month.

It doesn't protect against sexually transmitted infections (STIs).

 

Advantages and disadvantages of the IUD/IUS

The main advantages of the IUD and IUS is the effectiveness rate for preventing pregnancy. However, like other forms of contraception, there are additional benefits as well.

 

1)      Advantages

The longevity of the devices makes this contraception very low maintenance. Instead of remembering to take a pill everyday, the IUD can last up to 10 years and the IUS up to 5 years.

They can be used when breastfeeding without influencing the mother's milk.

They can be removed any time you wish and your fertility returns back to normal.

If you fall ill and have diarrhoea or vomit, the effectiveness of the IUD/IUS is not compromised. This is the same for taking medications.

They are good options if you're sensitive to oestrogen.

They can reduce pain and discomfort associated with your period. This includes cramps, length of your period and heavy flow. For some women, the IUS stops periods entirely.

 

2)      Disadvantages

Both devices do not offer protection for sexually transmitted infections. The only contraceptive that significantly reduces your chances are barrier methods such as condoms.

Some women experience spotting and bleeding. This often stops after a few months but if it doesn't, you can get the device removed.

The devices can make periods heavier, painful and longer. Again, this may improve after a few months and may not be the case for every woman.

Some women don't want to stop their periods as it's a good indication the contraceptive has worked, and maybe they aren't so troublesome in the first place.

Side effects can include headaches, acne and breast tenderness. Again, this should reduce over time.

Whilst uncommon, one disadvantage of the IUS are cysts on the ovaries. These are usually small and can disappear without treatment.
