Hi Curious, Welcome! Do you have elevated calcium (Ca) levels? Generally high dosages of vitamin D are used when you're vitamin D deficient. If you do have high Ca levels you really need to see your doctor asap. I had hypercalcemia, several years ago, and my vit D was very low, but taking a large dose of D didn't lower my Ca levels.
Can you make an appointment with your doctor or call to find out what else they plan on doing, if your Ca is high? Elevated Ca can be very serious, so please see your doctor to find out what the plan is.
