Perhaps the biggest question question mark over long term thyroxine is its ability to cause osteoporosis. One study of long term thyroxine users showed no evidence of reduced bone density (Lancet, 1992; 340: 9-13 while another study of premenopausal women with Hashimoto's disease on thyroid replacement therapy demonstrated that they had lower bone mineral density.

Thyroid replacement treatment is usually taken for life. There are different brands of levothyroxine available. Do not change brands without first consulting your doctor or pharmacist.
