Invitad3

Colecalciferol, the active ingredient in Invitad3, is a Vitamin D (Colecalciferol) presented as an oral supplement for oral use. It is used to address vitamin D deficiency and to support bone health in individuals at risk of osteomalacia or rickets. By increasing intestinal absorption of calcium and phosphate, it promotes bone mineralization.

GNH USA supplies Invitad3 as a licensed, GDP‑compliant international pharmaceutical supplier, providing the product to hospitals, pharmacies, transplant centres and clinics across global markets, ensuring quality and regulatory compliance.

Invitad3 (colecalciferol) is used in the vitamin D pathway to correct deficiency and maintain skeletal health.

- Vitamin D deficiency: restores adequate serum 25‑hydroxyvitamin D levels. - Osteomalacia/rickets prevention: helps prevent the development of soft bone disease in at‑risk populations. - Bone health support: contributes to normal bone mineralization and calcium homeostasis.

Colecalciferol may cause adverse reactions, which are generally dose‑dependent and vary in frequency.

Common Side Effects: - Hypercalcemia: elevated blood calcium levels causing nausea or fatigue. - Gastrointestinal discomfort: mild abdominal pain or constipation. - Headache: transient mild headache.

Serious or Rare Side Effects: - Hypercalciuria: excessive urinary calcium excretion leading to kidney stones. - Allergic reactions: rash, itching, or swelling of the face and throat. - Severe hypercalcemia: confusion, cardiac arrhythmias, or renal impairment.

When using Invitad3, consider the following precautions to ensure safe and effective therapy.

- Assess baseline vitamin D status: measure serum 25‑hydroxyvitamin D before initiating therapy. - Monitor calcium levels: periodic testing is advised, especially in patients with renal disease. - Caution in hypercalcemia: avoid use in individuals with known high calcium concentrations. - Use with care in sarcoidosis or granulomatous diseases: these conditions may increase active vitamin D production. - Pregnancy and lactation: consult a healthcare professional before use, as safety data are limited. - Store at room temperature: keep in the original container, protect from moisture and direct sunlight.

Colecalciferol can interact with several medicines, affecting its absorption or metabolism.

Major Interactions (Avoid): - Thiazide diuretics: may increase risk of hypercalcemia. - Vitamin A excess: combined high doses can lead to hypercalcemia. - Calcium supplements: concurrent high doses can cause elevated calcium levels.

Moderate Interactions (Monitor Closely): - Anticonvulsants (e.g., phenobarbital, phenytoin): may enhance vitamin D metabolism, reducing effectiveness. - Glucocorticoids: can impair vitamin D activation and increase bone loss. - Orlistat: may decrease absorption of fat‑soluble vitamins including vitamin D.
