My specialty pharmacy said Tymlos make bones more brittle. They had to by law read an explanation of the drug from the Tymlos company to me. I heard all anabolics and all bisphosphonates make the bones more brittle but less prone to fragility fractures. So if you have an accident and break a bone it can be harder to heal and some people say you may never heal.
Basically we can’t break a bone from an accident now.
