Should my grandmother stop taking calcium and/or Fosamax if her creatinine test came back at 1.3?

Question

My grandmother recently had a creatinine test that was at 1.3. Apparently, this is elevated. In the past, it had been normal.

My mother thinks that my grandmother should stop taking her daily calcium supplement (which is a 66% RDA pill in calcium carbonate form) and also her weekly Fosamax until her creatinine is back to normal.

Since my grandma has significant osteoporosis, I'm not sure this is a good idea. Is it worth ceasing her Fosamax and calcium? How relevant are these two supplements to kidney function?

Thanks!

Answer 1

If the calcium level is too high it can be an indication of kidney stones (an example only) but I would not recommend that she stop her medications until after discussing the results with the doctor at length to see what they mean.
