The Dr's. order clearly stated 200 mgm daily. When I questioned this at pharmacy, they showed me the bottle label, which stated for each tab of 950 200 mgm would be absorbed. I cannot find any statement to that effect in the references I have at my disposal. Pharmacy said they had no means of copying it & that particular Cal Cit would not be in any PDR. I explained this as straight forward as I could for home care staff. Do you have anything that would help me? Thanks. Linda
