Second-most commonly prescribed drug for older adults is linked to bone loss

Summary of article on NY PostA new study from Johns Hopkins Medicine suggests a link between the widely used thyroid medication levothyroxine (e.g., Synthroid) and increased bone loss in older adults, even those with normal thyroid function. The study, involving 445 participants, found that levothyroxine users experienced greater bone mass and density loss over six years compared to non-users. This raises concerns, especially given that a substantial portion of prescriptions may be issued unnecessarily to older adults. The researchers advise those taking levothyroxine to discuss potential risks, such as bone loss and osteoporosis, with their doctors. While levothyroxine treats hypothyroidism, the study indicates potential adverse effects that should be considered in relation to the benefits. The findings will be presented at the Radiological Society of North America's annual meeting.
