Contents of the Package Leaflet
Vitamin D3 Kern Pharma oral solution contains colecalciferol (vitamin D3). Vitamin D3, which is fat-soluble, can be found in some foods and is produced by the body when the skin is exposed to sunlight. Vitamin D promotes calcium absorption in the kidneys and intestines, helping to form bone. Vitamin D deficiency is the main cause of rickets (inadequate mineralization of bones in children) and osteomalacia (inadequate mineralization of bones in adults).
Vitamin D3 Kern Pharma is indicated for the prevention and treatment of vitamin D deficiency, due to lack of intake, lack of sun exposure, or altered intestinal absorption of fats; in adults, adolescents, and children with an identified risk of vitamin D deficiency.
It can also be used as an adjunct in the prevention and treatment of bone loss (osteoporosis) in patients with inadequate vitamin D and/or calcium intake.

If you take more Vitamin D3 Kern Pharma than you should
Toxicity due to excess vitamin D is characterized by hypercalcemia (high levels of calcium in the blood). The most frequent symptoms in case of overdose are: loss of appetite (anorexia), nausea, vomiting, diarrhea, excessive thirst, excessive urine production over 24 hours, weakness, nervousness, itching, and dehydration, and high levels of calcium in the blood and urine (hypercalcemia and hypercalciuria) in clinical analyses.
Hypervitaminosis D can also cause more severe disorders (cardiac, vascular, among others).
Moderate cases of hypervitaminosis can be treated simply by reducing or stopping the consumption of vitamin D. In cases of more severe hypercalcemia, glucocorticoids or calcitonin can be administered to reduce blood calcium levels.
In case of overdose or accidental ingestion, consult your doctor, pharmacist, or go to a medical center, or call the Toxicology Information Service, phone 91 562 04 20, indicating the medication and the amount ingested.
