Choosing bisphosphonate FDCs
Fixed-dose combinations (FDCs) of risedronate or alendronate with supplements of calcium and/or vitamin D are only suitable for people with osteoporosis who cannot obtain sufficient calcium and/or vitamin D from the diet and sun exposure. 1 Be aware that vitamin D doses in these FDCs are not sufficient for treating moderate or severe vitamin D deficiency. 1,2
Risedronate and alendronate are available with both calcium and vitamin D. Alendronate is available with vitamin D alone and risedronate is available with calcium alone.
