# CALCITRIOL 0.25 MCG + ELEMENTAL CALCIUM 500 MG ## Short Description **Calcitriol 0.25 mcg + Elemental Calcium 500 mg** is a combination supplement/medicine used to support **calcium balance and bone health** in selected patients with calcium or vitamin D-related disorders. **Calcitriol** is the biologically active form of vitamin D. It helps the body absorb calcium from the intestine and regulate calcium and phosphate metabolism. **Elemental calcium** provides calcium needed for normal bones, teeth, muscles, nerves, and other physiological functions. Because calcitriol is a potent active vitamin D compound, this combination should be used according to medical advice and should not be combined indiscriminately with other high-dose calcium or vitamin D products. --- ## Key Benefits * Helps maintain **calcium levels** in the body. * Supports normal **bone and tooth mineralization**. * Calcitriol improves intestinal absorption of calcium. * Supports normal **muscle and nerve function**. * Helps regulate calcium and phosphate metabolism. * May be prescribed for selected conditions involving impaired vitamin D activation or calcium metabolism. * Provides calcium together with active vitamin D for patients who require both. --- ## Uses / Indications Calcitriol + elemental calcium may be prescribed for selected conditions such as: ### 1. Calcium and Vitamin D Deficiency May be used when supplementation with calcium and active vitamin D is medically appropriate. ### 2. Hypocalcemia Calcitriol can help increase intestinal calcium absorption and support correction of low calcium levels when used under medical supervision. ### 3. Certain Kidney-Related Bone Disorders Patients with chronic kidney disease may have impaired conversion of vitamin D into its active form. Calcitriol may be prescribed in selected cases to help regulate calcium and phosphate metabolism. ### 4. Hypoparathyroidism Calcitriol may be used as part of treatment for hypoparathyroidism, where calcium regulation is impaired. ### 5. Bone Health The combination may support bone mineralization when calcium and active vitamin D supplementation is clinically indicated. > **Important:** Calcitriol is not simply equivalent to ordinary vitamin D supplements. It is an active vitamin D compound with a greater potential to raise blood calcium levels. --- ## How It Works ### Calcitriol 0.25 mcg Calcitriol is the **active form of vitamin D (1,25-dihydroxyvitamin D₃)**. It acts on vitamin D receptors and helps: * Increase intestinal absorption of calcium. * Increase intestinal absorption of phosphate. * Regulate calcium levels in the bloodstream. * Support normal bone mineralization. * Influence parathyroid hormone regulation. ### Elemental Calcium 500 mg Calcium provides the mineral required for: * Bone and tooth structure * Muscle contraction * Nerve transmission * Blood clotting * Normal cellular function ### Combined Effect Calcitriol helps the body **absorb and utilize calcium**, while the calcium component provides the mineral itself. --- ## Dosage & Administration **Take this medicine exactly as prescribed by your doctor.** The appropriate dose depends on: * Blood calcium level * Kidney function * Parathyroid hormone levels * Underlying medical condition * Dietary calcium intake * Other vitamin D or calcium products being used ### General Administration * Take the tablet with water. * Follow the prescribed schedule. * It may be taken with or without food depending on the specific product instructions. * Do not exceed the prescribed dose. * Do not take additional calcium or vitamin D supplements unless recommended by your healthcare professional. ### Monitoring Patients receiving calcitriol may require monitoring of: * Serum calcium * Serum phosphate * Kidney function * Parathyroid hormone (PTH), where appropriate ### Missed Dose Take the missed dose when remembered unless it is close to the next scheduled dose. **Do not take two doses at once** to compensate for a missed dose. --- ## Side Effects ### Common Side Effects Possible side effects, particularly when calcium levels become elevated, include: * Nausea * Vomiting * Constipation * Abdominal discomfort * Reduced appetite * Headache * Weakness ### Symptoms of High Calcium Excessive calcium levels (**hypercalcemia**) are an important concern with calcitriol. Symptoms may include: * Excessive thirst * Frequent urination * Nausea * Vomiting * Constipation * Abdominal pain * Muscle weakness * Fatigue * Confusion * Loss of appetite ### Serious Effects Severe or prolonged hypercalcemia can cause: * Kidney stones * Kidney impairment * Abnormal heart rhythms * Calcium deposits in tissues Seek medical attention if symptoms suggest significant hypercalcemia or if severe weakness, confusion, persistent vomiting, or markedly increased thirst and urination develop. --- ## Precautions & Warnings ### Hypercalcemia Do not use calcitriol without appropriate medical advice if you have **high blood calcium levels**. Excessive intake can cause serious hypercalcemia. ### Kidney Disease Patients with kidney disease may require careful monitoring of calcium, phosphate, and kidney function. ### Kidney Stones Tell your doctor if you have a history of: * Kidney stones * Hypercalciuria * Calcium-containing kidney stones ### Other Vitamin D Products Do not take additional vitamin D, calcitriol, or high-dose calcium supplements without medical advice. Combining multiple products can increase the risk of hypercalcemia. ### Sarcoidosis and Similar Conditions Some granulomatous disorders can increase sensitivity to vitamin D and increase calcium levels. Inform your doctor if you have such a condition. ### Dehydration Adequate hydration may be important, particularly in patients at risk of kidney stones or elevated calcium. ### Children Use in children should be supervised by a healthcare professional because the dose is highly dependent on age, condition, and laboratory results. --- ## Drug Interactions ### Other Calcium Supplements Taking additional calcium can increase the risk of **hypercalcemia**. ### Vitamin D Supplements Other vitamin D products can have additive effects with calcitriol and should not be taken without professional advice. ### Thiazide Diuretics Medicines such as hydrochlorothiazide can reduce urinary calcium excretion and may increase the risk of hypercalcemia when combined with vitamin D-related therapy. ### Digoxin High calcium levels can increase the risk of **cardiac arrhythmias** in patients taking digoxin. ### Magnesium-Containing Products High amounts of magnesium-containing antacids or laxatives may be problematic, particularly in patients with impaired kidney function. ### Cholestyramine Cholestyramine can reduce absorption of certain fat-soluble substances and may interfere with vitamin D-related therapy. ### Mineral Oil Long-term use of mineral oil may reduce absorption of fat-soluble vitamins. ### Phosphate Supplements Additional phosphate-containing medicines or supplements may alter calcium-phosphate balance. Always tell your doctor or pharmacist about all prescription medicines, OTC medicines, vitamins, and herbal supplements you use. --- ## Storage Information * Store according to the **manufacturer's recommended temperature**. * Keep tablets in their original packaging. * Protect from excessive heat, moisture, and direct sunlight. * Keep the container tightly closed. * Keep out of reach of children. * Do not use after the expiry date. * Do not use tablets if the packaging is damaged or the tablets appear abnormal. --- ## Prescription Status **Calcitriol 0.25 mcg + Elemental Calcium 500 mg may be prescription-only or pharmacist-supplied depending on the country and specific formulation.** Because calcitriol can significantly affect calcium levels, medical supervision may be required, particularly for long-term treatment.
