Lrcal-D3 Tablet is a combination pharmaceutical formulation containing Calcium 250 mg and Vitamin D3 1000 IU, designed to support bone health and prevent or treat calcium and vitamin D deficiencies. Calcium is an essential mineral critical for the development and maintenance of strong bones and teeth, playing a vital role in muscle function, nerve transmission, and vascular contraction. Vitamin D3 (cholecalciferol) facilitates the intestinal absorption of calcium and phosphorus, thereby enhancing bone mineralization and reducing the risk of osteoporosis and fractures. Lrcal-D3 is indicated for individuals with inadequate dietary calcium intake, patients with osteoporosis, osteomalacia, rickets, or those at risk of vitamin D deficiency due to limited sun exposure or malabsorption syndromes. This combination is also beneficial in postmenopausal women, elderly patients, and individuals undergoing corticosteroid therapy. The tablet should be administered as per the prescribing physician’s guidance, typically once daily, preferably with meals to enhance absorption. Caution is advised in patients with hypercalcemia, renal calculi, or hypersensitivity to any component. Regular monitoring of serum calcium and vitamin D levels is recommended during prolonged therapy to avoid toxicity. Lrcal-D3 Tablet offers a convenient and effective approach to maintaining optimal calcium and vitamin D status, thereby promoting skeletal health and overall well-being.
