Calcidol should be taken as prescribed by a healthcare provider or according to the patient information leaflet on the over-the-counter product. It is sold in tablet or liquid form, depending on the product, and this dosage varies from one condition to another, age group and vitamin D level. The examples of usage are listed in the following:

Adults: Generally, the dose is one tablet or a single dose of liquid taken daily, as recommended by a healthcare provider.

Children: The dose varies based on age and weight.

For Deficiency: The dose is much higher in cases of significant deficiency. A healthcare provider may even give a loading dose for some time to rapidly increase the levels of vitamin D.

Calcidol should be taken with food to enhance its absorption. Dosage should be followed strictly, and more than the recommended amount should not be taken unless recommended by a doctor.

Calcidol works through its use as an agent to treat vitamin D deficiency. Once administered, calcidiol is absorbed in the intestine, becomes available in the circulation and reaches the liver. Within the liver, it undergoes the necessary metabolism into its active form, calcitriol.

Calcitriol serves for various essential purposes:

Calcium Absorption: Calcitriol enhances the absorption of calcium from the intestines into the blood. Proper levels of calcium maintain bone density, muscle function, and nerve transmission.

Bone Health: Since calcitriol supports calcium and phosphate absorption, there will be proper mineralization of bones to prevent diseases like osteomalacia and osteoporosis.

Maintains blood phosphate levels: It has also a regulatory role on phosphate that needs to be within the bloodstream for healthful bones because phosphate ions in their hydroxyapatite form have bound themselves with calcium ions which lend rigidity to bones

Maintenance of Immune System Functionality Vitamin D maintains the functions of the immune system for host’s protection against infections as well as inflammation.

Since Calcidol supplies calcidiol directly, it enables the body to maintain adequate vitamin D levels to ensure that calcium and phosphate balance is properly regulated, as well as supports bone health.

Even though Calcidol is typically regarded as safe for use under clinical conditions, adverse effects might still occur in some individuals who consume vitamin D supplements. The side effects from vitamin D supplements often are:

Hypercalcemia (high calcium levels): If taken in excessive amounts, vitamin D can cause an increase in calcium levels in the blood, leading to symptoms such as nausea, vomiting, weakness, and confusion.

Gastrointestinal Issues: Some individuals may experience nausea, vomiting, constipation, or stomach discomfort when taking vitamin D supplements.

Fatigue: In some cases, individuals may feel unusually tired or fatigued when taking vitamin D supplements.

Kidney Stones: Long-term use of high doses of vitamin D can lead to an increased risk of developing kidney stones, especially if the calcium level in the body is also elevated

Before using Calcidol, a patient must observe the following warnings and precautions:

Pre-existing Conditions: People with conditions such as hypercalcemia, kidney disease, or history of kidney stones must seek the opinion of a healthcare provider prior to using Calcidol. Vitamin D may exacerbate these conditions.

Interactions with Medications: Calcidol may interact with certain medications, including corticosteroids, anticonvulsants, and diuretics, among others. It is important to inform your healthcare provider of all medications you are taking.

Pregnancy and Breastfeeding: While vitamin D is essential during pregnancy and breastfeeding, excessive vitamin D intake can be harmful. It is important to follow the advice of a healthcare provider to ensure appropriate dosing.

Avoid Overuse: The patient should not take more than the recommended dose of Calcidol since excessive doses of vitamin D can result in toxicity, which may cause serious diseases like hypercalcemia and renal damage.

1. Thiazide Diuretics: These medications, like hydrochlorothiazide, may increase the risk of hypercalcemia when used with calcidol, as they reduce calcium excretion in the kidneys.
2. Corticosteroids: Long-term use of corticosteroids can decrease calcium absorption and potentially reduce the effectiveness of calcidol in managing vitamin D deficiency.
3. Anticonvulsants: Medications like phenytoin and phenobarbital can induce liver enzymes, which may accelerate the metabolism of calcidol, reducing its effectiveness.
4. Calcium Supplements: Combining calcidol with calcium supplements increases the risk of hypercalcemia, so calcium levels should be closely monitored to prevent toxicity.

Dosage of Calcidol would depend on the degree of deficiency, age, and the specific health need. The following are general guidelines but a healthcare provider should be consulted for specific recommendations:

Adults: Mild deficiency often requires a usual dosage of one tablet daily or in a liquid solution equivalent. Major deficiency would need a high dose which is administered over a short-term period.

Children: Dosages for children vary but are administered at lesser quantities as required depending on age, weight, and vitamin D level.

Vitamin D Insufficiency: People with insufficient levels of vitamin D may be given a higher dose, but once levels normalize, they may switch to a maintenance dose.

It’s important to regularly monitor vitamin D levels when taking Calcidol to avoid overdosing or underdosing.

Calcidol is usually bought over the counter in some countries, especially in low doses. A prescription may be required in other situations, especially when higher doses are needed. The need for a prescription will depend on regulations in the country, the extent of the deficiency, and the assessment of the patient’s health status by the healthcare provider.

It is best to consult a medical professional before beginning treatment with Calcidol, especially if you have any pre-existing medical condition or are taking other drugs that might interact with vitamin D.
