Yes, My Doctor Has Prescribed Sensipar, Which Will Lower My

Yes, My doctor has prescribed Sensipar, which will lower my blood calcium since I have high parathyroid hormone levels. I am very concerned since it has very bad & sometimes deadly side effects. In May of this year I had a cancerous tumor removed from my breast along with lymph nodes , one of which had
a "speck" in it. I chose not to take radiation, chemo or Fumara which pill was recommended for 5 years.however would severely strip the calcium from my body. I already have osteoporosis which an ultrasound reveals has stripped the bone in my left arm & my right hip . I take a thyroid pill which keeps me from taking other pill until 4 hours later, and I take Citracal for Calcium(1 serving) Directions are to be careful taking with other medicines. I don't know when to take this medication .
