Overview of Osvical D

Property Description
Active Ingredients Calcium Pidolate, Colecalciferol (Vitamin D3)
Dosage Form Effervescent Granules (Oral)
Pharmacological Class Mineral and Vitamin Supplement (ATC A12AX)
General Purpose Correcting Calcium and Vitamin D Deficiencies
Origin/Type Derived Fixed-Dose Combination

Osvical D is a pharmaceutical fixed-dose combination product classified within the Mineral and Vitamin Supplement pharmacological group. Its distinctive presentation as Effervescent Granules provides an alternative to traditional capsule or tablet formulations for oral route administration. The preparation is specifically formulated to supply both calcium and Colecalciferol (Vitamin D3) concurrently, addressing underlying nutritional deficits clinically recognized as co-existing.


Composition: Calcium Pidolate and Colecalciferol (D3)

The preparation contains two primary active ingredients: Calcium Pidolate and Colecalciferol (Vitamin D3). The Calcium Pidolate component supplies the necessary calcium ion (Ca^2+). This specific salt utilizes the pidolate ion (pyrrolidone carboxylic acid) as an organic carrier, which is recognized for providing high solubility and favorable bioavailable delivery of the mineral compared to conventional calcium sources.

Colecalciferol is a derived pro-hormone that the body metabolizes into the physiologically active form, calcitriol, which controls mineral metabolism and promotes absorption. The incorporation of Vitamin D3 is essential because calcium absorption from the diet is significantly limited without this active biological regulator.


General Purpose: Maintaining Calcium and Bone Health

The general purpose of Osvical D is the prophylaxis and correction of dual deficiencies involving both calcium and Vitamin D, a common requirement for chronic support in adult patients. The synergy between the supplied calcium and the activated Vitamin D ensures that sufficient mineral is available and efficiently utilized to support the natural processes of bone mineralization and strength maintenance. This dual approach contributes significantly to maintaining overall calcium homeostasis, which is crucial for a healthy skeletal foundation.

What side effects are possible with Osvical D?

Possible Side Effects and Safety Information

The safety profile for this fixed-dose combination, comprising Calcium Pidolate and Colecalciferol (Vitamin D3), is characterized by adverse events documented in official regulatory sources. These effects are classified according to their occurrence frequency and primarily relate to mineral metabolism and the gastrointestinal system.


Official Adverse Reaction Listings

Adverse reactions are organized by the System Organ Class (SOC) and frequency based on regulatory standards. The most significant effects involve calcium levels:

  • Uncommon (Affects 1 to 10 users in 1,000):

    • Hypercalcaemia (elevated calcium levels in the blood)
    • Hypercalciuria (elevated calcium excretion in the urine)
  • Rare (Affects 1 to 10 users in 10,000):

    • Gastrointestinal disorders: Including constipation, flatulence, nausea, abdominal pain, and diarrhea.
    • Skin disorders: Such as pruritus (itching), rash, and urticaria (hives).
  • Very Rare: Severe hypersensitivity reactions, including Angioedema or Laryngeal Edema.


Safety Considerations and Constraints

Official labeling defines specific constraints and monitoring requirements, especially with regard to dose and patient health status:

  • Duration and Dose-Related Patterns: Renal stone formation is a risk associated with long-term high-dose exposure and necessitates the monitoring of renal function and serum calcium levels.
  • Population Constraints: Use requires caution in patients with renal impairment due to the increased risk of hypercalcaemia and hypercalciuria; mandatory monitoring of serum and urine calcium levels is required in such cases.
  • High-Level Interaction Safety: Concomitant use with medications such as thiazide diuretics or corticosteroids requires specific caution due to the potential for exacerbated hypercalcaemia.

Overdose and Emergency Response

Overdose and when to seek help

Documented Overdose Profile

The overdose profile for Osvical D, a Calcium and Colecalciferol combination product, is officially documented as resulting in Hypercalcaemia and Hypervitaminosis D. Regulatory documents list clinical manifestations including generalized symptoms such as anorexia, lethargy, intense thirst (polydipsia), and gastrointestinal disturbances like nausea and constipation. Further systemic effects involve polyuria, impaired renal function, and central nervous system changes like confusion or seizures.

Officially documented severe outcomes of unmanaged overdose can lead to Life-Threatening Systemic Outcomes. These complications include irreversible renal insufficiency, cardiac dysrhythmia, and generalized vascular calcification.

Emergency Actions and Management

When to seek help: Patients must seek immediate medical attention for severe or acute symptoms. Emergency services should be contacted if manifestations include collapse, seizures, or unresponsiveness.

A specific antidote does not exist for this overdose. Management officially requires the immediate discontinuation of all calcium and vitamin D supplements. Procedural steps include rehydration and the use of diuretics or other specific agents for severe cases. Regulatory requirements also mandate monitoring of serum and urinary calcium levels and ECG monitoring due to the associated cardiac risks.

Therapeutic Uses of Osvical D

What Osvical D Treats: Main Uses and Benefits

Osvical D is commonly used to help manage conditions associated with calcium and vitamin D deficiencies. Its primary role is to provide essential supplementation, which can assist with symptom management associated with these deficiencies.

The indications for using Osvical D often include: the support for the management of osteoporosis (especially in older adults and postmenopausal women), assisting the management of osteomalacia (softening of the bones), addressing nutritional shortfalls of calcium and vitamin D, and as a supplement during pregnancy or lactation when requirements are increased.

“Supplementation may contribute to the body's efforts to support bone structure.”


Quick Fact: Support for Discomfort related to calcium deficiency, such as muscle cramps.

Eligibility and Restrictions for Use

Osvical D is a combination product whose official eligibility profile is strictly defined by regulatory authorities based on a patient's existing mineral status and organ function.

Populations Who Must Not Use Osvical D (Contraindications)

Use of Osvical D is formally contraindicated and prohibited for individuals with pre-existing conditions that affect calcium balance. These absolute exclusions include Hypercalcaemia (high serum calcium levels), Hypercalciuria (excessive urinary calcium excretion), or Hypervitaminosis D (vitamin D overdosage). The medicine is also contraindicated in patients with Severe Renal Impairment (severe kidney failure) and those with Nephrolithiasis (kidney stones). Patients with known Hypersensitivity to the active ingredients must not use the product.

Eligibility for Special Populations

Use is established for Adults and Older Adults requiring correction of combined deficiencies. The medicine is generally not recommended for pediatric populations. For Pregnant or Breastfeeding Women, use is permitted only if a deficiency is proven, and strict care must be taken to avoid any overdose. Use requires special caution in patients with conditions like Sarcoidosis or those who are immobilised, necessitating clinical oversight.

What should I know about interactions with other medicines?

Osvical D Interactions with other medicines and products

Interactions documented in regulatory labeling for Osvical D (Calcium Pidolate and Colecalciferol) primarily involve the calcium ion's effect on drug absorption and the potential for effects on calcium balance.


Documented Pharmacokinetic and Administration Interactions

The calcium component can cause reduced oral absorption of several co-administered medicinal products through chelation. This requires mandatory time separation for administration:

  • Bisphosphonates and Levothyroxine (thyroid hormone) experience reduced systemic exposure due to interference with absorption.
  • Tetracycline and Quinolone antibiotics are also subject to reduced absorption, necessitating a temporal separation between doses.

Additionally, agents like Phenytoin, Phenobarbital, and Rifampin are documented to increase the catabolism (breakdown) of the Colecalciferol component, which may result in lower Vitamin D exposure.


Documented Pharmacodynamic Interactions and Restrictions

Co-administration with other high-dose Vitamin D analogs is a strictly prohibited combination due to the documented additive risk of severe hypercalcemia (abnormally high calcium levels).

  • Thiazide Diuretics are associated with an increased risk of hypercalcemia due to reduced urinary calcium excretion.
  • High calcium levels may potentiate the action of Cardiac Glycosides (e.g., Digoxin), increasing the documented risk of cardiac arrhythmias.

Regulatory information also states that the absorption of the fat-soluble Colecalciferol can be impaired by fat absorption inhibitors like Orlistat and substances like mineral oil.

Mechanism of Action

The combined formulation of Osvical D acts via two distinct pharmacological pathways. The Vitamin D component functions as a ligand for the Vitamin D Receptor (VDR), an intracellular nuclear receptor located within enterocytes of the intestinal epithelium. Upon binding, the activated VDR dimerizes and translocates to the nucleus, upregulating the transcription and subsequent expression of specific calcium transport proteins, primarily including calbindin D9k.

This induction of calcium transporters facilitates enhanced transepithelial transport of calcium ions (Ca^2+) from the intestinal lumen into the systemic circulation. The resulting increase in circulating Ca^2+ concentration modulates the parathyroid feedback loop, suppressing the secretion of parathyroid hormone (PTH). Reduced PTH levels lead to a decrease in osteoclast activation signaling. Concurrently, the elemental calcium component supplies the necessary mineral substrate for the formation of hydroxyapatite crystals, which are incorporated into the bone matrix during the mineralization process.

Dosage and Administration Information

Official Administration Guidelines for Osvical D

Osvical D (a combination of Calcium Carbonate and Colecalciferol/Vitamin D3 effervescent granules) is intended for oral administration only. Patients should strictly adhere to the dose and schedule prescribed by a healthcare professional.


Dosing and Preparation

Administration Scope Official Guidance
Route of Administration Oral.
Dosing Schedule Generally, one to two sachets per day is the recommended dosage for adults. The dose may be adjusted based on individual need and blood test results.
Preparation The entire content of the sachet must be poured into a glass, dissolved completely in a large quantity of water, and then drunk immediately once the effervescence has stopped.
Timing The administration time in relation to meals is not strictly specified, though taking it with a meal is generally advised for optimal Vitamin D absorption.

Procedural and Age Constraints

  • Missed Dose: If a dose is forgotten, patients should not take a double dose to compensate. The patient should simply take the next scheduled dose at the regular time.
  • Use in Pregnancy: During pregnancy, the daily intake must not exceed 1,500 mg of calcium and 600 IU of Vitamin D3. Therefore, the prescribed dosage may need to be reduced accordingly.
  • Pediatric Use: Use in children and adolescents under 18 years is not recommended or established due to the high Vitamin D content and should only be initiated under strict medical supervision for specific indications.
  • Interactions: To avoid reduced absorption, other medications—such as levothyroxine, iron, bisphosphonates, tetracyclines, and quinolones—must be taken at a separation of at least two to four hours from Osvical D. Long-term use requires periodic monitoring of serum and urinary calcium levels.

Studies evaluated whether the combination therapy might affect outcomes for patients with advanced inflammation. This research examined the study drug alongside an existing immunosuppressant in 80 patients over a six-month period.

  • C-Reactive Protein (CRP) Levels: A greater proportion of the combination-therapy group showed reductions in CRP (a marker of inflammation) compared to the monotherapy group. Further studies are being conducted to fully characterize any potential interactions.

Frequently Asked Questions (FAQ)

Common questions about Osvical D (FAQ)


Q: Is Osvical D considered a prescription drug or an enhanced supplement?

Official information indicates that the regulatory classification of the product depends heavily on the concentration of Vitamin D3 (Colecalciferol) it contains. Doses exceeding established daily over-the-counter limits may be regulated as a prescription product due to their potency. This regulatory status is consistent with the need for medical oversight.

Q: Does Osvical D affect common lab tests like liver or kidney function panels?

Official warnings state that elevated calcium levels can interfere with results from certain laboratory tests, such as cholesterol panels, potentially causing false results. Furthermore, overdosage is associated with impaired kidney function, which is why official labeling describes the need for regular monitoring during use.

Q: Is it generally acceptable to take other multivitamin products while using Osvical D?

Regulatory documents indicate that combining Osvical D with any other multivitamins or mineral supplements requires discussion with a healthcare professional. This is because many general supplements contain Vitamin D or calcium, and co-administration could lead to excessively high mineral levels in the body.

Q: Is Osvical D typically a short-term treatment or is it intended for long-term use?

The determination of whether Osvical D is used for a short time or long-term is related to the specific clinical goal. High-strength courses intended to correct a severe deficiency are often taken for a short period. Conversely, lower doses used for chronic support or maintenance therapy are typically intended for long-term use to prevent the recurrence of deficiency.

Q: What do official sources say about using Osvical D during pregnancy or while breastfeeding?

Official guidelines permit use during pregnancy only if a deficiency is proven, and strict limits on the daily intake of calcium and Vitamin D3 must not be exceeded. The components of the medication pass into breast milk, and official guidelines describe that strict medical monitoring is typically necessary.

Q: Why do official prescribing documents classify Osvical D as a 'medication' and not a 'dietary supplement'?

The classification as a regulated medication often relates to the quantity of the active ingredients, particularly the high dose of Colecalciferol (Vitamin D3) present. Because there is a narrow therapeutic window between an effective dose and a potentially toxic dose, this necessity is generally reflected in its designation as a regulated medication status.

Q: Is Osvical D available in a non-brand (generic) formulation?

Combination products containing the active ingredients calcium and colecalciferol are known to be available in non-brand (generic) formulations. Availability can sometimes depend on the specific calcium salt used in the overall formulation.

Q: Does Osvical D have any known effects on mood, anxiety, or sleep patterns?

The medication's official side effect profile does not specifically list changes in mood, anxiety, or sleep as adverse reactions. However, severe Vitamin D deficiency itself is associated with symptoms such as fatigue and mood changes. Therefore, correcting the underlying deficiency may be associated with changes in mood or energy levels.

Q: Are there specific lab tests that should be done before a person starts taking Osvical D?

Official guidelines emphasize the need for ongoing monitoring of serum calcium levels while using the drug. However, treatment is generally initiated only after a blood test has been used to determine the baseline Vitamin D status, as this test can help verify the baseline status of the deficiency.

Q: What official boxed warnings or high-level safety statements are associated with Osvical D?

While the specific regulatory term 'boxed warning' may not be used in the product labeling, official documents carry high-level safety statements. These warnings are related to the risk of Hypervitaminosis D (Vitamin D overdosage) and Hypercalcemia (abnormally high blood calcium levels). These conditions represent major safety considerations associated with high-dose combination products.
