DEEVIT-0.25

# Calcitriol 0.25 mcg ## Short Description **Calcitriol 0.25 mcg** is the active form of **vitamin D3 (vitamin D)**. It helps the body absorb calcium and phosphate and plays an important role in maintaining healthy bones and regulating blood calcium levels. Calcitriol is used for certain conditions involving impaired vitamin D metabolism, including **hypocalcemia associated with chronic kidney disease, hypoparathyroidism, and related mineral-bone disorders**, depending on the patient's condition and the specific product indication. Because calcitriol is a potent, active form of vitamin D, it should be used under medical supervision with appropriate monitoring of **calcium and phosphate levels**. --- ## Key Benefits * Helps maintain **normal calcium levels** in the blood. * Improves **intestinal absorption of calcium and phosphate**. * Supports normal **bone mineralization and bone health**. * Helps manage low calcium levels associated with certain medical conditions. * Can help correct disturbances in **calcium-phosphate metabolism**. * Particularly useful when the body cannot adequately convert vitamin D into its active form. --- ## Uses / Indications Calcitriol 0.25 mcg may be prescribed for: 1. **Hypocalcemia associated with chronic kidney disease**, particularly in patients with impaired vitamin D activation. 2. **Hypoparathyroidism**, when active vitamin D therapy is required. 3. Certain forms of **renal osteodystrophy** or chronic kidney disease–mineral and bone disorder. 4. Other disorders of calcium and vitamin D metabolism when specifically prescribed by a healthcare professional. > The approved indications can vary depending on the country, formulation, and manufacturer. --- ## How It Works Calcitriol is the **biologically active form of vitamin D**. Normally, vitamin D undergoes activation in the liver and kidneys. In some diseases, especially advanced kidney disease, the body's ability to produce active vitamin D is reduced. Calcitriol acts directly on vitamin D receptors and: * Increases **calcium absorption from the intestine**. * Helps regulate **phosphate absorption and metabolism**. * Supports normal bone mineralization. * Helps regulate **parathyroid hormone (PTH)** production. Through these effects, calcitriol helps restore balance in calcium and phosphate metabolism. --- ## Dosage & Administration ### Usual Adult Dose The appropriate dose depends on the medical condition, calcium level, kidney function, and response to treatment. For many adult indications, treatment may be started at approximately **0.25 mcg once daily**, with the dose adjusted by the healthcare professional according to laboratory results and clinical response. **Do not change the dose without medical advice.** ### How to Take Calcitriol * Take exactly as prescribed. * It may generally be taken **with or without food**. * Take it at approximately the same time each day if prescribed as a daily medicine. * Swallow capsules/tablets whole unless your particular product instructions say otherwise. * Do not take additional vitamin D or calcium supplements unless recommended by your healthcare professional. ### Monitoring During treatment, your doctor may monitor: * Serum **calcium** * Serum **phosphate** * Kidney function * PTH levels when appropriate * Other mineral-bone parameters Because calcitriol can increase calcium levels, laboratory monitoring is particularly important. ### Missed Dose If you miss a dose, take it when you remember unless it is nearly time for your next dose. **Do not double the dose** to make up for a missed dose. --- ## Side Effects ### Common or Possible Side Effects Some people may experience: * Headache * Nausea * Vomiting * Abdominal discomfort * Constipation * Loss of appetite * Weakness or fatigue Many adverse effects are related to **excess calcium levels (hypercalcemia)**. ### Symptoms of Excess Calcium Contact your healthcare professional if you develop: * Nausea or vomiting * Constipation * Increased thirst * Frequent urination * Loss of appetite * Muscle weakness * Headache * Confusion * Unusual tiredness ### Serious Side Effects Seek medical attention if symptoms of severe hypercalcemia occur, such as: * Severe weakness * Significant confusion or changes in mental status * Irregular heartbeat * Severe dehydration * Persistent vomiting Long-term excessive calcium levels can contribute to **kidney problems or kidney stones**. --- ## Precautions & Warnings Before taking Calcitriol 0.25 mcg, inform your doctor if you: * Have **high blood calcium levels (hypercalcemia)**. * Have kidney disease or a history of kidney stones. * Have high phosphate levels. * Have heart disease. * Have previously experienced vitamin D toxicity. * Are taking calcium or vitamin D supplements. * Are pregnant, planning pregnancy, or breastfeeding. ### Important Hypercalcemia Warning Calcitriol can increase calcium absorption and therefore may cause **hypercalcemia** if the dose is too high or if excessive calcium/vitamin D is consumed. Do not take extra vitamin D, calcium supplements, or vitamin D-containing products unless specifically recommended. ### Regular Monitoring Patients receiving calcitriol may require regular blood tests to ensure that calcium and phosphate levels remain within the appropriate range. --- ## Drug Interactions Tell your doctor or pharmacist about all medicines, vitamins, and supplements you use. ### Calcium Supplements Taking excessive amounts of calcium together with calcitriol can increase the risk of **hypercalcemia**. ### Other Vitamin D Products Avoid taking additional vitamin D or vitamin D analogues unless specifically prescribed, as combined use can increase the risk of excessive vitamin D activity and high calcium levels. ### Magnesium-Containing Products Large amounts of magnesium-containing antacids or laxatives may cause **high magnesium levels**, particularly in people with impaired kidney function. ### Thiazide Diuretics Medicines such as hydrochlorothiazide can reduce urinary calcium excretion. Combined use with calcitriol may increase the risk of **hypercalcemia**. ### Digoxin High calcium levels may increase the risk of **cardiac arrhythmias** in people taking digoxin. Patients receiving both medicines may require careful monitoring. ### Cholestyramine and Certain Bile-Acid Sequestrants These medicines may reduce absorption of fat-soluble vitamins and may potentially interfere with vitamin D-related therapy. Always provide your healthcare professional with a complete list of your medicines and supplements. --- ## Storage Information * Store Calcitriol 0.25 mcg at **room temperature**, according to the manufacturer's instructions. * Keep the medicine in its **original packaging**. * Protect it from excessive heat, moisture, and direct light. * Keep out of reach and sight of children. * Do not use the medicine after the **expiry date**. * Dispose of expired or unused medicine appropriately according to local pharmaceutical disposal guidance. --- ## Prescription Status **Calcitriol 0.25 mcg is generally a prescription medicine.** It should be used under the supervision of a qualified healthcare professional because the dose must be individualized and excessive vitamin D activity can cause **hypercalcemia and related complications**.
