Researchers are raising concerns about levothyroxine, the second most commonly prescribed thyroid medication for older adults in the U.S., as new findings link its use to bone loss.
Levothyroxine or L-thyroxine is a synthetic version of the hormone thyroxine commonly given to patients with underactive thyroid. People with underactive thyroid or hypothyroidism show signs such as fatigue, increased heart rate, depression, dry skin and hair, muscle cramps, constipation, weight gain, and memory issues.
