Copper intrauterine devices (IUDs)
What is an intrauterine device (IUD)?
- An IUD is a type of birth control.
- It may be known as a LARC device or a long-acting reversible contraceptive method of birth control.
- There is only 1 copper-containing IUD.
- It is called Paragard® and can stay in your uterus for up to 10 years to keep you from getting pregnant.
- Some women who use a copper IUD get heavier or longer periods than they had before.
- Paragard® also can be used for emergency contraception.
- You may be able to get pregnant right away after an IUD is removed.
- Your provider can help you choose the right IUD for you.
A copper IUD might be a good choice if you:
- Want contraception that is very effective at preventing pregnancy.
- Do not want or cannot have hormones.
- Such as if you have deep blood clots in your legs.
- Do not want big changes in your period.
- Such as not having any periods, bleeding, or spotting when you might not expect it.
- The exception is if you have heavy and/or painful periods. Paragard® can make these worse.
- Want birth control for at least 1 year. It will last up to 10 years.
Paragard® IUD benefits are:
- It works right after it is inserted.
- Less than 1 in every 100 women who use these devices get pregnant during the first year of using them.
- IUDs are very safe.
- You do not need to take birth control daily.
- Few side effects
- It does not have estrogen.
- Take the IUD out when you want, if you want to get pregnant.
- If you use an IUD for many years, it can cost less overall than many other types of birth control.
- That is because there are no costs after you have it put in.
The downsides of an IUD are:
- An IUD does not protect you against sexually transmitted infections (STIs). Only condoms protect from STIs.
- Your partner can still use a condom to protect against STIs.
- Very rarely the IUD will come out by itself (expulsion).
- You will need a new IUD if this happens.
- Call your provider if you are worried that it has come out.
- The first cost is higher than the cost of other methods. Many IUDs are covered by insurance.
- Only a provider can put in or take out an IUD.
If you become pregnant while using an IUD:
- While very unlikely, you can get pregnant with IUDs.
- Take a urine pregnancy test if you miss any periods and feel like you may be pregnant.
- If you have a positive pregnancy test, please call the clinic right away. We will need to see you as soon as we can.
After Paragard® is put in
It is always exciting to start something new–especially birth control that:
- Can last for up to 10 years
- Is completely hormone free
- Is more than 99% effective
It may take some time for your body to adjust to Paragard® ® as you get used to hormone-free protection.
Right after Paragard® is put in, you may feel:
- Temporary pinching and cramping
- Dizziness
- Nausea
- Faint
Call your health care provider if you have:
- Heavy menstrual bleeding
- Severe abdominal pain
- Temperature of 100.4 degrees F (or 38 degrees C)
In the first 1 to 3 months, you may have:
- Irregular bleeding
- Such as random spotting to bleeding like a period
- Intermittent cramping–if you have cramping, you may take:
- Take Ibuprofen 600 mg every 6 hours and/or take acetaminophen (Tylenol) 650 mg every 4 to 6 hours
Keep your follow up appointment about 6 weeks after the IUD is put in.
In the first 3 to 6 months:
- Your body should be used to the Paragard® ®, but each person is different.
- If you have any questions or concerns, talk to your provider.
- Your periods can be heavier.
- You can have more cramping.
Checking your strings:
- Paragard® is designed to fit comfortably and stay inside your uterus.
- Do the monthly string check you have been shown.
- Make an appointment with your health care provider right away if:
- You think the Paragard® has moved
- You can no longer feel the string
- It feels shorter than before
- Use backup birth control.
Paragard® does not protect against sexually transmitted infections (STIs) or human immunodeficiency virus (HIV). You should use a condom with new partners or if you are concerned about being exposed.
