1.

What is THORENS and what is it used for
THORENS oral drops, solution contains cholecalciferol (Vitamin D). Vitamin D
is found in some foods and is also produced by the body when the skin is exposed to
sunlight. Vitamin D helps the body absorb calcium in the kidneys and intestines and
supports bone formation. A deficiency of Vitamin D is the main cause of rickets (disrupted
mineralization of bones in children) and osteomalacia (insufficient mineralization of bones
in adults).
THORENS oral drops, solution is used to prevent Vitamin D deficiency and to treat it in
adults, adolescents, and children at risk of Vitamin D deficiency.
THORENS oral drops, solution may also be used as an adjunct in patients taking medicines
for osteoporosis.

2. Important information before taking THORENS
