What do I need to know about having an IUD insertion? Prior to insertion, an assessment of your medical history and suitability for this method will happen. This assessment enables you to ask any questions you may have and be certain that it is the most suitable method for you. Insertion of an IUD involves a procedure. Some women find insertion uncomfortable. This can be managed with the use of local anaesthetic into the cervix. If there are reasons to anticipate difficulties then a woman may choose or be advised to have a sedative or general anaesthetic. The device should be inserted by a medical practitioner trained in the procedure.
