Introduction About ARACHITOL 6LAC INJECTION
ARACHITOL 6LAC INJECTION contains Cholecalciferol which belongs to the group of medicines called Vitamin D analogs. It is a form of vitamin D used in the management of vitamin D deficiency conditions and for certain bone conditions such as thinning of the bone (osteoporosis) which will be given to you with other medicines.
Deficiency of vitamin D may occur when your diet or lifestyle does not provide you with enough vitamin D or when your body requires more vitamin D (for instance when you are pregnant).
Along with this management, your doctor might advise you to eat and drink foods that are rich in calcium. Your doctor might want to take certain blood tests prior to the management to understand the existing condition.
ARACHITOL 6LAC INJECTION is not recommended for use if you have high levels of calcium in your blood (hypercalcaemia) or urine (hypercalciuria), are suffering from liver problems, kidney failure, kidney stones or have a tendency to form kidney stones, high levels of vitamin D in blood (hypervitaminosis).
Before taking ARACHITOL 6LAC INJECTION, inform your doctor if you have any kind of heart disease or narrowing of the arteries, sarcoidosis (a multisystem chronic inflammatory condition which can affect your lungs, heart and kidneys) or if you are taking any medicines or food containing vitamin D.
ARACHITOL 6LAC INJECTION should be used with caution among women who are pregnant and breastfeeding because too much vitamin D may harm your baby. ARACHITOL 6LAC INJECTION can only be given to children and adolescents aged 12 and above. Consult your doctor if you experience any unusual side effects during management with this medicine.
Uses Of ARACHITOL 6LAC INJECTION

Benefits of ARACHITOL 6LAC INJECTION
- Helps restore vitamin D levels in individuals with vitamin D deficiency.
- Enhances the absorption of calcium and phosphorus from the intestine, supporting healthy bone mineralization.
- Helps improve bone strength and density in people with vitamin D deficiency.
- Supports the management of osteoporosis when used as part of a comprehensive treatment plan that includes adequate calcium intake.
- Helps manage osteomalacia (soft bones) and rickets associated with vitamin D deficiency.

- Provides a high-dose vitamin D option for patients who require rapid correction of deficiency when oral supplementation is unsuitable or inadequate, as determined by a healthcare professional.
How ARACHITOL 6LAC INJECTION Works
Arachitol 6 Lac Injection contains Cholecalciferol (Vitamin D3) 600,000 IU, a fat-soluble vitamin essential for calcium and phosphorus metabolism. After administration, vitamin D3 undergoes activation in the liver and kidneys to form calcitriol (active vitamin D), which regulates calcium homeostasis and bone mineralization.
1. Increases Intestinal Calcium Absorption
- Cholecalciferol is converted into active vitamin D (calcitriol).
- Calcitriol increases the production of calcium-binding proteins in the intestine.
- This enhances the absorption of calcium from food into the bloodstream.
- Improved calcium absorption helps maintain healthy bones and teeth.
2. Enhances Phosphorus Absorption
- Active vitamin D also increases intestinal absorption of phosphorus.
- Calcium and phosphorus work together to form strong bone mineral.
- Adequate phosphorus supports normal skeletal development and bone maintenance.
3. Supports Bone Mineralization
- Maintains appropriate calcium and phosphorus concentrations in the blood.
- Promotes deposition of these minerals into bones.
- Helps improve bone strength and supports normal bone remodeling.
4. Regulates Parathyroid Hormone (PTH)
- Adequate vitamin D levels help maintain normal parathyroid hormone activity.
- This supports balanced calcium metabolism and reduces excessive calcium loss from bones.
5. Supports Muscle and Immune Function
- Vitamin D receptors are present in muscle and immune cells.
- Maintaining adequate vitamin D levels supports normal muscle performance and healthy immune function.
How to use ARACHITOL 6LAC INJECTION

Thiazide diuretics reduce calcium excretion through the kidneys. When combined with high-dose vitamin D, blood calcium levels may increase excessively.
Examples:
- Hydrochlorothiazide
- Chlorthalidone
- Indapamide
Possible Effect:
- Hypercalcemia (high blood calcium)
- Kidney stones
- Confusion
- Excessive thirst
- Frequent urination
- Muscle weakness
Recommendation:
- Periodic monitoring of blood calcium levels may be required
2. Digoxin and Other Cardiac Glycosides
High vitamin D doses may increase calcium levels, which can enhance the effects and toxicity of digoxin.
Examples:
- Digoxin
- Digitoxin
Possible Effect:
- Irregular heartbeat
- Palpitations
- Nausea
- Dizziness
- Increased risk of cardiac arrhythmias
Recommendation:
- Close monitoring of calcium levels and heart rhythm may be necessary.
3. Corticosteroids
Long-term corticosteroid therapy may reduce calcium absorption and decrease the effectiveness of vitamin D.
Examples:
- Prednisolone
- Dexamethasone
- Hydrocortisone
- Methylprednisolone
Possible Effect:
- Reduced vitamin D activity
- Lower calcium absorption
- Reduced improvement in bone mineralization
4. Antiepileptic Medicines
Certain anticonvulsants increase the breakdown of vitamin D in the liver, reducing its effectiveness.
Examples:

- Carbamazepine
- Primidone
Possible Effect:
- Lower vitamin D levels
- Reduced calcium absorption
- Increased risk of vitamin D deficiency and bone disorders
5. Orlistat
Orlistat reduces the absorption of dietary fats, which may also decrease the absorption of vitamin D.
Possible Effect:
- Reduced vitamin D absorption
- Lower blood vitamin D levels
- Reduced treatment effectiveness
Recommendation:
- Additional monitoring or supplementation may be required.
6. Bile Acid Sequestrants
These medicines reduce intestinal absorption of fat-soluble vitamins, including vitamin D.
Examples:

More Information
1. Why Vitamin D Is Essential for Bone Health
Vitamin D plays a vital role in maintaining healthy bones by helping the body absorb calcium and phosphorus, two minerals required for bone formation and strength. Without adequate vitamin D, only a limited amount of calcium from the diet is absorbed, which may affect bone mineralization over time.
Why This Is Important
- Supports healthy bone development and maintenance.
- Helps maintain normal blood calcium levels.
- Promotes proper bone mineralization throughout life.
- Supports healthy teeth and skeletal function.
- May help improve muscle strength associated with vitamin D deficiency when levels are restored.
2. Why Blood Tests May Be Recommended During Treatment
Since Arachitol 6 Lac Injection contains a high dose of vitamin D3 (600,000 IU), healthcare professionals may recommend laboratory monitoring to ensure appropriate vitamin D levels and avoid excessive supplementation.
Monitoring May Include
- Serum 25-hydroxyvitamin D [25(OH)D] levels.
- Blood calcium and phosphorus levels.
- Kidney function tests in individuals at higher risk.
- Follow-up assessments to determine whether additional doses are required.
Patient Education
- Do not receive repeat injections earlier than advised.
- Avoid self-medicating with additional high-dose vitamin D supplements unless prescribed.
- Inform your healthcare professional if you are already taking calcium or multivitamin supplements.
3. Lifestyle Tips to Support Healthy Vitamin D Levels
Although Arachitol 6 Lac Injection helps restore vitamin D levels, healthy lifestyle habits can support long-term bone health.
Healthy Habits
- Include vitamin D-rich foods such as fatty fish (salmon, sardines, mackerel), egg yolks, fortified milk, fortified cereals, and fortified dairy products in your diet.
- Consume calcium-rich foods like milk, yogurt, cheese, soy products, almonds, and green leafy vegetables, if appropriate.
- Get regular sunlight exposure on uncovered skin according to your healthcare professional's advice, while following safe sun exposure practices.
- Engage in regular weight-bearing and muscle-strengthening exercises, such as walking or resistance training, to support bone health.
- Avoid smoking and limit alcohol consumption, as both may negatively affect bone health.
Why These Habits Matter
Combining prescribed vitamin D therapy with a balanced diet, appropriate sunlight exposure, and regular physical activity supports healthy bones, muscles, and overall skeletal well-being.
