Any treatment besides calcium for osteopenia or do you need to wait till osteoporosis?

Plenty of options: Actually vitamin d is more important than calcium. If you have osteopenia, take 500mg of calcium and 2000u of vit d and get a vit d level checked. If your vit d is low, you will continue to lose bone. Other meds that treat osteopenia include bisphosphonates and evista.

"FRAX" score helps: Agree with dr. Cabry. Calcium, vitamin d, and also weight bearing exercise are helpful to prevent osteoporosis. Ask your doctor for your frax score (based on demographic information and your DEXA scan results) to see if your risk of fracture is high enough to suggests prescription drugs.
