Repatha for high cholesterol

I have a relative who can’t take statins or Zetia and her doctor recommended Repatha. I am not familiar with this medication. Anyone know anything about it?

A review of cholesterol meds and uses. We’re now moving into injectable meds with Repatha so it’s a whole new scenario. I’ve never been a fan of statins overall to reduce cholesterol but every case is different.
