The most important thing to consider, is that medicine for bone health, ie Fosamax, generic Fosamax (Alendronate), Boniva, Actonel, and Reclast use the kidney to eliminate the medication that is not bound to the bone.  There is no detrimental effect on the liver.  I would encourage you to continue your current regimens of calcium, vitamin D, weight-bearing and strenghth-training exercises.  If you continue to have bone loss, the rational for medicine to prevent fractures often outweigh the risks.  This is a conversation you need to explore with your practitioner.
