I have long-term osteoporosis. The doctors prescribed me oral medications such as Ostenil 70, Risentros 35 and most recently Calperos 1000, after which I had bloating, constipation and nausea. After a year, it turned out that I had anemia (8,2). Calperos was discontinued because he was the main cause of this disease. Currently, hemoglobin has improved (10,4). Unfortunately, I have too low a level of calcium (5.10 mg/do; reference range 30.075 mg/dl) and calcium (61.20 mg/24; reference range 100.00-300.00) in dzm. I need to raise this level of calcium and its concentration in the DMS to be able to switch to prolia treatment. The doctor replacing the previous doctor, despite my misgivings, again prescribed me Calperos 1000. Previous side effects (bloating, constipation, nausea, dizziness) appeared again. I can't take this medicine because I'll run out. What medicine could I use instead? Is Molekin D3 + Vit. k or some other could take his place? I would appreciate your reply, Aldona.
