Vutrisiran is in a class of medications called small interfering RNAs (siRNAs). It works by decreasing the amount of abnormal proteins and the amount of abnormal protein deposited in the body’s tissues, which decreases nerve damage.

Vutrisiran injection comes as a solution (liquid) to be given subcutaneously (under the skin). It is usually given by a doctor or a nurse in a clinic every 3 months.
