DEAR DOCTOR K: I am currently on a bisphosphonate "drug holiday." How will I know if, or when, I should go back on the drug?
DEAR READER: After menopause, loss of bone (osteoporosis) can lead to crippling bone fractures. Drugs called bisphosphonates slow bone loss. Below, I've put a table with detailed information about these drugs. But bisphosphonates can cause troubling side effects. The pills can cause burning in the esophagus. And a small number of users have developed bone loss in the jaw and in the large bone in the upper legs (the femur), causing the femur to break.
