Lecalcif (Colecalciferol)

Colecalciferol is converted in the liver to 25‑hydroxyvitamin D and then in the kidney to the active hormone 1,25‑dihydroxyvitamin D. This active form binds to vitamin D receptors in intestinal cells, stimulating the synthesis of calcium‑binding proteins that increase absorption of calcium and phosphate, essential for bone mineralization.

The dosage of Lecalcif is individualized by a qualified health professional based on the patient’s serum vitamin D level, age, weight, renal function, and clinical condition. The prescriber determines the appropriate strength and duration, and patients should follow the specific instructions provided on the prescription label.

Colecalciferol is generally considered safe in pregnancy and lactation when used at recommended doses, as vitamin D is essential for fetal bone development and maternal health. However, supplementation should only be undertaken under medical supervision to avoid excessive calcium levels, which could pose risks to both mother and infant.

To order Lecalcif, submit an enquiry on the product page at gnhindia.com, specifying the required quantity. GNH India works with hospitals, pharmacies, and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details (including any cold‑chain requirements), and necessary import documentation.

Lecalcif provides colecalciferol, the natural D3 form, which has higher bioavailability and a longer half‑life than vitamin D2 (ergocalciferol). Compared with high‑dose prescription preparations, Lecalcif is an over‑the‑counter product offering flexible dosing, but it may require physician guidance for patients with severe deficiency or comorbidities.

Lecalcif should be stored at room temperature, below 25 °C, in its original packaging to protect it from moisture and direct sunlight. Keep the container tightly closed and out of reach of children. Do not store in bathrooms or near heat sources, as excessive humidity can affect product stability.

Lecalcif is taken orally, usually with or without food, as directed by the prescribing clinician. The tablet or capsule is swallowed whole with a glass of water. Patients should not crush or chew the dosage form unless specifically instructed, to maintain proper absorption.

The most serious adverse events associated with excessive vitamin D intake are hypercalcemia, which can cause nausea, vomiting, weakness, kidney stones, and cardiac arrhythmias. Rarely, allergic reactions such as rash, swelling, or anaphylaxis may occur. Patients should seek medical attention if they experience these symptoms.

Lecalcif should be avoided or used with caution in individuals with known hypersensitivity to colecalciferol, severe renal impairment, hypercalcemia, or granulomatous diseases such as sarcoidosis that can increase vitamin D activation. Pregnant or breastfeeding women should only use it under medical supervision, and children require pediatric dosing guidance.
