How It Works
Leqvio contains inclisiran, which is a small interfering RNA (siRNA). It targets a substance in the liver called PCSK9. By targeting PCSK9, Leqvio helps your body remove more LDL-C from your blood.
How to Take It

Pregnancy & Breastfeeding
Stop taking Leqvio when you know you are pregnant. Lowering cholesterol may not be helpful during pregnancy and Leqvio could potentially harm the baby.

If you miss a planned dose by less than 3 months, get the shot as soon as possible and continue with your original schedule. If you miss a planned dose by more than 3 months, restart the dosing schedule with a shot now, another in 3 months, and then every 6 months.
