Calvimax-D Tablet 30s - Calcium Carbonate 500mg + Vitamin D3 200IU | Incepta

What is Calvimax-D Tablet?

Calvimax-D Tablet is a calcium and vitamin D3 combination supplement manufactured by Incepta Pharmaceuticals Ltd. It combines Calcium Carbonate with Vitamin D3 to support bone health and treat calcium deficiency-related conditions.

Generic Name and Composition

Each tablet contains Calcium Carbonate 1250 mg, equivalent to elemental Calcium 500 mg, plus Vitamin D3 (Cholecalciferol) 200 IU.

Indications

• Treatment and prevention of osteoporosis
• Osteomalacia and rickets
• Tetany and hypoparathyroidism
• Inadequate calcium intake in diet (as advised by physician)
• Increased calcium requirement during pregnancy and lactation
• Supplementation in elderly patients at risk of calcium deficiency

How It Works - Mechanism of Action

Calcium Carbonate provides elemental calcium required for bone mineralization, neuromuscular function, and various enzymatic processes. Vitamin D3 enhances intestinal absorption of calcium and phosphate after conversion to its active form (calcitriol) in the liver and kidneys, working synergistically with calcium to support bone formation, density, and overall skeletal health.

Dosage and Administration

• Usual adult dose: 1 tablet once or twice daily, or as directed by physician
• Best taken with or after meals to enhance calcium absorption and reduce gastrointestinal discomfort
• Swallow tablet with a full glass of water
• Duration of therapy should be individualized based on calcium/vitamin D status and clinical condition

Side Effects

Common: Mild gastrointestinal discomfort, constipation, bloating

Uncommon: Nausea, flatulence

Rare: Hypercalcemia, hypercalciuria, and milk-alkali syndrome with excessive or prolonged high-dose use

Drug Interactions

Tetracyclines and Fluoroquinolone Antibiotics: Calcium reduces absorption of these antibiotics - separate dosing by at least 2-3 hours

Levothyroxine: Calcium can reduce absorption of levothyroxine - separate dosing by at least 4 hours

Thiazide Diuretics: May increase risk of hypercalcemia when combined with calcium/vitamin D supplementation

Digoxin: Hypercalcemia may increase risk of digoxin toxicity - use with caution

Iron Supplements: Calcium may reduce iron absorption - separate dosing if both are required

Contraindications

• Known hypersensitivity to calcium carbonate, vitamin D3, or any excipient
• Hypercalcemia or hypercalciuria
• Conditions associated with vitamin D toxicity (hypervitaminosis D)
• Severe renal impairment with risk of soft tissue calcification

Pregnancy and Lactation

Calcium and Vitamin D3 supplementation at recommended doses is generally considered safe and often recommended during pregnancy and lactation to meet increased physiological demand. Please follow your physician's specific dosing recommendations during this period.

Precautions and Warnings

• Use with caution in patients with a history of kidney stones or renal impairment
• Avoid excessive intake beyond recommended doses to prevent hypercalcemia
• Patients with sarcoidosis or other granulomatous diseases should use vitamin D supplements cautiously due to increased sensitivity
• Periodic monitoring of serum calcium may be advised with long-term use, especially in at-risk patients
• Separate timing from other medications known to interact with calcium (see Drug Interactions)

Overdose

Overdose may lead to hypercalcemia with symptoms such as nausea, vomiting, constipation, confusion, and in severe cases, renal impairment or cardiac arrhythmias. Discontinue use and seek immediate medical attention. Management is generally supportive, including hydration and monitoring of serum calcium under medical care.
