It is important to reiterate that Tymlos does not cause brittle bones, nor does Forteo. The mechanism by which these two drugs work builds quality bone, unlike Prolia or bisphosphonates, which do create brittle bone if used too long. See McCormick's new book or ask your doc to confirm. Here is the actual insert: note that not a single human has gotten cancer from these drugs and the black box warning has been removed.

TYMLOS may cause serious side effects including possible bone cancer (osteosarcoma), decrease in blood pressure when you change position, increased blood calcium (hypercalcemia), and increased urine calcium (hypercalciuria). The most common side effects of TYMLOS in women with postmenopausal osteoporosis include dizziness, nausea, headache, fast heartbeat, feeling tired (fatigue), upper stomach pain, and spinning feeling (vertigo). The most common side effects of TYMLOS in men with osteoporosis include redness at injection site, dizziness, joint pain, swelling at injection site, pain at injection site, bruising, abdominal bloating, diarrhea, nausea, abdominal pain, and bone pain.
