WHAT BONEFOS IS
USED FOR
Certain cancers increase bone
breakdown and lead to an increased
amount of calcium circulating in
the bloodstream. This can result in
high calcium levels in the blood
(hypercalcaemia) or bone
destruction (osteolysis) which
increases your risk of bone
fractures and bone pain.
Bonefos works by stopping calcium
from coming out of your bones and
keeps your blood calcium at normal
levels (normocalcaemia). Bonefos
can be used to either bring your
blood calcium levels down to a
normal level (acute treatment) or to
keep it down at a normal level
(maintenance treatment).
Bonefos can also be used to treat
bone destruction due to breast
cancer and bone marrow cancer.
