Forteo side effects high calcium decreasing dosage to every other day

This is very interesting and helpful @gently. Timing the blood draw before the injection is a good idea. I take my Forteo at night before bed and will get the blood draw at 8:00 AM. Do you think it is alright to just skip the shot the night before?

My last blood test showed stage 2 Kidney failure. I never had this before. My docs just say that this is normal for my age. I have too much calcium in my urine, and my serum level was at 10 four months ago. You describe an interesting relationship between the kidneys and serum calcium.

Is it recommended to stop all supplements before a blood test? I can't seem to get a straight answer from my docs about this. I was told to stop calcium, and I see on this forum that I should stop collagen and biotin for CTX.

It sounds like I could cut back on Vitamin D. I take Magnesium. I am also taking Vitamin K2 MK7 and Boron to help the bones absorb calcium. I wonder if I am taking too many supplements.

drsuefowler,
I'd skip the night before injection. And I'd skip supplements the day before, mainly boron, d and calcium and any protein supplements.
Stage 2 kidney disease may be common in age. Under that rubric we can use the term normal.
Serum gfr is an estimated rate influenced by high protein intake, muscle building exercise, muscle loss and damage to muscles-- factors that aren't an indication of the loss of kidney function. Serum calcium and calcium in the urine can be affected by calcium and d intake.
Forteo increases urine calcium.
Precise ways of directly measuring GFR exist but are inconvenient and seldom employed.
I wonder too about all these supplements. I even take phosphatidylserine, but I laugh a little at myself.
I do get serum d levels twice a year and adjust intake accordingly. 20–50 ng/mL (50–125 nmol/L) I aim for 70nmol/L.
I'll be curious if you still register the estimated stage 2.
