What do I need to know about the ongoing use of an IUD? You will be given details of follow up at the time of the insertion. Generally, you are asked to attend for a follow up visit after insertion and/or any time concerns exist. You should contact your doctor if: if you miss a period or you feel you may be pregnant you experience pelvic pain or tenderness, fever or chills, offensive discharge or deep pain with intercourse you cannot feel the string or feel the string has lengthened you (or your partner) can feel the hard stem of the IUD The IUD needs to be replaced with a new device every 5 or 10 years depending on which device is inserted. However, if you have a copper IUD inserted after the age of 40, this expiry date can often be extended and the same device left in for a longer period of time. This is because you have a lower risk of falling pregnant in your late 40s and 50s. Please discuss further with your medical practitioner. It is important to keep a record of the date that replacement is due or remember a landmark event to arrange for replacement no later than this date. The IUD can easily be removed at any time. As fertility can return immediately after removal, it is important to consider alternative methods of contraception, before the IUD is removed, if trying to avoid pregnancy.
