Levonorgestrel-Releasing Intrauterine System Dosage

General Information on Using It

Some considerations to keep in mind while using levonorgestrel-releasing intrauterine system include the following:
 
  • This product is a small, plastic device that is placed into your uterus by a trained healthcare provider. It is usually inserted within seven days after your period starts, immediately after a first-trimester abortion or miscarriage, or at least six weeks after giving birth.  
 
  • The device is placed in the uterus using a slim, plastic inserter that comes with the medication. It only takes a few minutes for the device to be inserted.
 
  • You will need to return to your healthcare provider's office 4 to 12 weeks after insertion, and then at least once a year, to make sure the device is properly in place.
 
  • Some women experience some dizziness, pain, or bleeding during or right after placement. If your symptoms do not improve within 30 minutes, let your healthcare provider know. The device may not be placed properly.
 
  • Your healthcare provider may recommend a pain-reliever, such as acetaminophen (Tylenol®), before and/or after the device is placed. You can ask your healthcare provider about this.
 
  • You won't be able to feel levonorgestrel-releasing intrauterine system in your body, but will be able to feel the threads with your fingers at the top of your vagina (at your cervix). Do not pull on the threads, as doing so could displace the device.
 
  • You should check that the levonorgestrel-releasing intrauterine system is properly in place by feeling for the threads at least once a month after each menstrual period. If you do not feel the threads, or if you feel plastic, let your healthcare provider know right away. The device may not be properly placed and may not prevent pregnancy.
 
  • Although the product can remain in the uterus for three to five years, your healthcare provider can remove it at any time.
 
  • For the medication to work properly, it must be used as prescribed. If levonorgestrel-releasing intrauterine system is not inserted properly, or if it becomes misplaced, it may not prevent pregnancy.
 
  • If you are unsure about anything related to your dosage of the levonorgestrel-releasing intrauterine system, please talk with your healthcare provider, nurse, or pharmacist.
