Drug - Drug interaction

Inform your physician if you are taking any of the following medicine before taking Shelcal HD tablet:

1. Thyroid Medications (e.g., Levothyroxine)

• Interaction: Calcium can bind to levothyroxine and reduce its absorption, making the thyroid medication less effective.
• Effect: This may lead to suboptimal thyroid hormone levels and impaired thyroid function.
• Management: Take Shelcal HD at least 4 hours apart from thyroid medications to reduce this interaction.

2. Antacids (e.g., Aluminum or Magnesium-based Antacids)

• Interaction: Calcium can interact with aluminum or magnesium-based antacids and reduce their effectiveness. This is more of a concern in patients who need frequent antacid use.
• Effect: It can alter the absorption of calcium or other minerals and may cause gastrointestinal upset.
• Management: Avoid taking antacids and Shelcal HD simultaneously. Space the doses by at least 2 hours.

3. Diuretics (e.g., Thiazide diuretics)

• Interaction: Thiazide diuretics like hydrochlorothiazide can increase calcium levels in the blood by reducing calcium excretion through urine.
• Effect: This can lead to hypercalcemia (high calcium levels), especially when taking calcium supplements like Shelcal HD.
• Management: Regular monitoring of calcium levels is recommended when using both Shelcal HD and diuretics to reduce hypercalcemia.

4. Corticosteroids (e.g., Prednisone)

• Interaction: Long-term use of corticosteroids can reduce calcium absorption from the gut, leading to a higher risk of calcium deficiency.
• Effect: It can contribute to bone loss and increase the risk of fractures in patients on corticosteroids.
• Management: Adequate calcium supplementation (such as Shelcal HD) and vitamin D are recommended to mitigate bone loss. Regular monitoring of bone health is also advised.

5. Bisphosphonates (e.g., Alendronate)

• Interaction: Calcium supplements can interfere with the absorption of bisphosphonates, reducing their effectiveness in managing osteoporosis.
• Effect: This could lead to suboptimal outcomes for bone health.
• Management: Take calcium supplements (like Shelcal HD) at least 30 minutes after bisphosphonates, and preferably with a different meal.

6. Certain Antibiotics (e.g., Tetracyclines and Fluoroquinolones)

• Interaction: Calcium can bind to certain antibiotics (like doxycycline or ciprofloxacin), impairing their absorption and effectiveness.
• Effect: The antibiotic might be less effective at managing infections.
• Management: Take Shelcal HD and antibiotics at different times (preferably 2 hours apart) to reduce this interaction.

7. Iron Supplements

• Interaction: Calcium can inhibit the absorption of iron, leading to reduced effectiveness of iron supplements.
• Effect: This may result in continued iron deficiency or anemia.
• Management: Take iron supplements and Shelcal HD at least 2 hours apart to ensure proper absorption of both.

8. Phenytoin (Anticonvulsants)

• Interaction: Phenytoin can decrease the effectiveness of vitamin D, leading to lower calcium levels in the body.
• Effect: This may contribute to bone thinning and increased fracture risk.
• Management: Ensure adequate vitamin D and calcium intake, and monitor calcium levels regularly.

9. High-dose Vitamin D (Vitamin D Toxicity)

• Interaction: Excessive vitamin D can cause hypercalcemia when taken with calcium supplements, including Shelcal HD.
• Effect: This can lead to symptoms like nausea, vomiting, and kidney problems.
• Management: Avoid taking high doses of vitamin D without medical supervision. Always follow the prescribed dosage of Shelcal HD.

10. Magnesium Supplements

• Interaction: While less common, high doses of magnesium could potentially increase the risk of hypercalcemia when taken with Shelcal HD.
• Effect: It could lead to complications like kidney stones or kidney dysfunction.
• Management: Be cautious with the simultaneous use of high-dose magnesium supplements, and consult a healthcare provider for appropriate dosing.

More Information

How does the Shelcal HD tablet support bone health, reduce osteoporosis, and enhance calcium absorption?

Shelcal HD is a popular supplement that is designed to support bone health, reduce osteoporosis, and enhance calcium absorption. Here is how it works:

1. Supports Bone Health

• Shelcal HD contains calcium, vitamin D3, and magnesium all of which are essential nutrients for bone health.
• Calcium is the primary building block of bones, and it helps maintain bone density. It plays a crucial role in keeping bones strong and reducing conditions like osteopenia (low bone mass) and osteoporosis (brittle bones).
• Magnesium contributes to the structural development of bones and helps in the proper functioning of bones by promoting the activity of bone-building cells called osteoblasts.
• Together, these ingredients support the bone matrix, helping to maintain bone strength and integrity.

2. Reduce Osteoporosis

• Osteoporosis is a condition characterized by weakened bones and an increased risk of fractures. Calcium is vital for reducing this condition, and vitamin D plays a key role in its absorption.
• Vitamin D3 in Shelcal HD enhances the absorption of calcium from the digestive system and ensures that calcium is properly utilized in bone formation. Without sufficient vitamin D, the body may not be able to absorb enough calcium, increasing the risk of developing osteoporosis.
• A deficiency in calcium and vitamin D3 can lead to bone thinning, making bones more susceptible to fractures. Shelcal HD addresses these deficiencies, which can help reduce the onset of osteoporosis, especially in postmenopausal women, older adults, and people with limited sun exposure.

3. Enhances Calcium Absorption

• Vitamin D3 plays a vital role in enhancing the absorption of calcium from the gut. Calcium is not efficiently absorbed without adequate vitamin D levels. Therefore, Shelcal HD helps ensure that your body can absorb and use the calcium it receives from food and supplements.
• This combination of calcium and vitamin D3 is particularly important in people who may not get enough of these nutrients from their diet or sun exposure.

4. Additional Benefits

• Magnesium is often included in Shelcal HD because it helps to regulate calcium levels and supports bone mineralization. It also helps in maintaining proper muscle function, which is important for overall mobility and reducing the risk of falls and fractures in people with osteoporosis.
• The synergistic effect of these nutrients ensures that bone health is optimized, and calcium is absorbed efficiently, improving bone density, and reducing bone-related issues.

Shelcal HD is an effective supplement to promote strong, healthy bones by providing essential nutrients such as calcium, vitamin D3, and magnesium that work together to reduce osteoporosis, enhance calcium absorption, and support overall bone health.
