Hidroferol

Hidroferol is an oral vitamin D supplement containing calcifediol, a 25‑hydroxyvitamin D3 metabolite, marketed in the European Union as an over‑the‑counter product. It is supplied in tablet form (strength not specified) and is intended to raise circulating vitamin D levels. The preparation is classified as a vitamin D analog and is used to support calcium metabolism and bone health for individuals with limited sun exposure or dietary intake.

Hidroferol is indicated for the correction of low vitamin D status and for the prevention of bone‑related disorders associated with deficiency.

- Treatment of documented vitamin D deficiency in adults. - Prevention of osteomalacia in individuals at risk. - Support of bone health to reduce the risk of osteoporosis. - Adjunct therapy in chronic kidney disease where conversion to active vitamin D is impaired. - Management of malabsorption syndromes that limit dietary vitamin D absorption.

Adverse reactions to Hidroferol are generally dose‑related and may affect calcium balance or cause mild gastrointestinal symptoms.

Common: - Nausea or upset stomach. - Constipation or mild diarrhea. - Headache. - Transient fatigue. - Mild hypercalcemia (asymptomatic).

Serious: - Significant hypercalcemia with symptoms such as polyuria, polydipsia, or cardiac arrhythmia. - Nephrolithiasis (kidney stones) due to calcium precipitation. - Severe allergic reactions, including rash, pruritus, or angioedema. - Hypervitaminosis D leading to calcification of soft tissues.

Before using Hidroferol, consider the following safety points.

- Assess baseline serum calcium and 25‑hydroxyvitamin D levels to avoid excess supplementation. - Use caution in patients with a history of hypercalcemia, renal stones, or granulomatous diseases. - Monitor renal function periodically, especially in individuals with chronic kidney disease. - Pregnant or breastfeeding women should consult a healthcare professional before initiating therapy. - Do not exceed the recommended daily intake without medical supervision, as chronic excess can lead to toxicity. - Store the product away from moisture and keep out of reach of children.

Hidroferol may alter the effectiveness or safety of certain medications.

Avoid: - Thiazide diuretics, which can increase the risk of hypercalcemia. - Calcium supplements taken in high doses, potentially leading to excess calcium levels. - Vitamin A excess, which may potentiate vitamin D toxicity.

Use with caution: - Anticonvulsants such as phenobarbital or phenytoin that accelerate vitamin D metabolism. - Corticosteroids, which can reduce vitamin D activation. - Bisphosphonates, where concurrent high vitamin D may affect calcium homeostasis. - Certain cholesterol‑lowering agents (e.g., cholestyramine) that may impair absorption of fat‑soluble vitamins.
