Methylprednisolone and Strontium, a caution.
Methylprednisolone can cause bone loss when used repeatedly or chronically. Strontium supplements can raise apparent DXA bone density independent of true bone strength, complicating monitoring for glucocorticoid-induced osteoporosis.

Caution
What is happening. Methylprednisolone can cause bone loss when used repeatedly or chronically. Strontium supplements can raise apparent DXA bone density independent of true bone strength, complicating monitoring for glucocorticoid-induced osteoporosis.
Mechanism. Strontium in bone increases DXA attenuation and can overestimate BMD, while methylprednisolone suppresses bone formation and can increase resorption. The combination creates a monitoring problem rather than a timing problem.
Recommendation. If you use strontium while taking methylprednisolone, make sure it is recorded before DXA testing and osteoporosis decisions. Do not use strontium to self-treat steroid-induced bone loss without clinician guidance.
