Hypertrichosis associated with the use of C-type natriuretic peptide analogue: a case report

This unexpected pharmacological event, observed in a real-world setting, should be discussed with families prior to initiating treatment. Although hypertrichosis was not previously reported in clinical trials, it was not considered a serious adverse event. Further real-world data are needed to support therapeutic decisions and set appropriate expectations for families, patients, and healthcare providers. Additional evidence is required to better understand the pathophysiology underlying this phenomenon. In some cases, this undesirable adverse effect may influence clinical decision-making regarding treatment.
