Forteo side effects high calcium decreasing dosage to every other day

drsuefowler, calcium supplementation doesn't ususally affect serum level because your body borrows from the bone to keep it constant. Forteo or Tymlos can elevate calcium levels because your body controls calcium through parathyroid hormone. Generally either drug will elevate calcium levels transciently during the 16 to 24 hours after injection. You may want to time your serum draw before the injection. Elevated calcium levels with normal pth suggests primary hyperparathyroidism.
Excess calcium in the blood can depress kidney function. And reduced kidney function can increase serum calcium
Excess Vitamin D can cause excess calcium buildup in the blood. 800 IU would be a normal dose for you. You may want to lessen the dose or stop your dose before the same calcium test.
250 (I'm assuming) mg would be low dose calcium, same as mine.
I do hope Forteo works out for you. It's my favorite.

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.

Hi gently. I’m on Forteo and take 1200 mg of calcium daily through a combination of food and supplements, plus 2000 IU of vitamin D and k2. Do you think I should have my calcium levels tested now that I am 6 months into using teraparatide? Or other blood levels? My endocrinologist didn’t request any post drug testing. I took the initiative and had my family doctor ask for a CTX and P1NP which all looked good (the drug is working), but I haven’t repeated a 24 hour calcium urine test or anything else since taking the drug.
