How Shelcal Tablet works

Shelcal -OS Tablet is often prescribed for the management of calcium and vitamin D deficiencies. Alfacalcidol is a synthetic form of vitamin D, specifically vitamin D3. It plays a crucial role in calcium and phosphorus metabolism. It enhances the absorption of calcium and phosphorus from the intestines, promotes bone mineralization, and helps regulate parathyroid hormone (PTH) secretion. Calcium is a mineral that is essential for various physiological functions in the body, including the formation and maintenance of strong bones and teeth, blood clotting, and muscle function. Shelcal -OS Tablet helps ensure an adequate supply for these essential functions.

Quick tips

Follow the recommended dosage provided by your doctor.
While taking supplements, maintain a balanced diet that includes sources of calcium and vitamin D.
Periodic monitoring of calcium and vitamin D levels may be recommended.
Inform your doctor of any other medications or supplements you are taking to avoid potential interactions.
If you experience any unusual or severe side effects, such as gastrointestinal discomfort, nausea, or changes in urinary habits, notify your doctor promptly.
