I finally switched to one of these, Praluent, after the muscle pain interfered with me sleeping without excruciating leg cramps for more than an hour. Easy self-injections, much like a epi-pen every two weeks. With GoodRx the monthly cost is $225 without insurance coverage. My pharmacist was able to get me on a patient assistance plan with the makers so that my cost is $0.
I now no longer fear waking up gasping in pain from muscle cramps in my legs.
