Managing the risks of mood symptoms with LNG-IUS: a clinical perspective

Abstract

Introduction: Lack of awareness of reproductive hormone-related mood changes in the general population or limited acknowledgement of their existence by health care providers regularly contribute to fears or misconceptions about the link between hormonal contraception and potential mood changes. Recent media discussion linked the levonorgestrel intrauterine system (LNG-IUS 20 µg/d) to elevated cortisol levels and the possibility of panic attacks, anxiety, mood changes, sleep disturbance and restlessness. Efficacy of the LNG-IUS is based primarily on local effects but systemic effects, including a potential increase in mood symptoms, are a known risk and reflected in the product labelling for all LNG-IUS products. Objective: There is a need to improve communication to the public and health care providers around potential risk of mood disorders in order to facilitate ‘informed choice’ amongst women considering an LNG-IUS as their contraceptive method and directly address the fears of women currently using an LNG-IUS. Results: We propose a simple and brief, step-by-step process that can be embedded within current counselling that explores and clarifies the potential risk of developing mood symptoms prior to placement of LNG-IUS. It also addresses concerns from women using an LNG-IUS who either present with mood symptoms or are concerned about potential onset. Conclusion: Mood symptoms with use of LNG-IUS are uncommon; however, all women, including those who may experience an increased sensitivity to certain progestins, should be counselled appropriately to raise awareness of the potential risk within an informed discussion around effectiveness, benefits and possible adverse events.
