In 2011, Chris fractured three vertebrae. We discovered he had developed osteoporosis, caused by a clinical trial drug he was taking. His doctor wanted him to receive an infusion to help reverse the bone loss as quickly as possible. She told him the most common side effects are flu-like symptoms.

I researched the drug options after we got home to see if they would jeopardize his health. I learned they can cause the femur—the strongest bone in the body—to break. But what I found next terrified me.
