CALFERON D TABLET belongs to the class of 'nutritional supplements', primarily used to treat low blood calcium levels. CALFERON D TABLET effectively treats various conditions caused by low calcium levels in the body like Vitamin D deficiency, osteoporosis (weak and brittle bones), hypoparathyroidism (parathyroid glands make low levels of calcium in the body), latent tetany (a muscle disease with low blood calcium levels), and rickets or osteomalacia (softening or deforming of bones due to lack of calcium). Vitamin D deficiency occurs when your body has low Vitamin D levels and is caused due to inadequate nutrition, intestinal malabsorption, or lack of sunlight exposure.

CALFERON D TABLET consists Calcium (mineral) and Cholecalciferol (Vitamin D3). Calcium is a mineral that is used to prevent or treat a calcium deficiency. It provides essential nutrients to maintain bone formation and maintenance. Cholecalciferol is a form of Vitamin D and helps maintain blood calcium and phosphorus levels and bone mineralisation. It is used to treat and prevent bone disorders, such as rickets and osteomalacia.

Your doctor will decide the dosage based on your medical condition. CALFERON D TABLET is likely safe to consume. In some cases, it may cause side effects like constipation and stomach upset. These side effects do not require medical attention and gradually resolve over time.

If you are known to be allergic to CALFERON D TABLET or its inactive components, inform your doctor. Please tell your doctor if you have heart/kidney/liver/blood vessel diseases, kidney stones, hypercalcaemia (high calcium levels), hypervitaminosis D (high vitamin D levels), low levels of bile, phosphate imbalance, and malabsorption syndrome (difficulty absorbing nutrition from food) before starting CALFERON D TABLET.  Pregnant or breastfeeding women should consult their doctor before taking CALFERON D TABLET.This supplement is safe to use in children when advised by the doctor.

Let your doctor know if you are allergic to CALFERON D TABLET or its inactive components. CALFERON D TABLET is not recommended if you have hypercalcaemia (high calcium levels), hypervitaminosis D (high vitamin D levels), and malabsorption syndrome (difficulty absorbing nutrition from food). Brief your medical history if you have any heart/kidney/liver/blood vessel diseases, kidney stones, sarcoidosis (growth of inflammatory cells in different parts of the body), Crohn's disease (inflammatory bowel disease), Whipple's disease (bacterial infection affecting joints and digestive system), achlorhydria (little or no stomach acid), low levels of bile, and phosphate imbalance. It is advised to check with your doctor before using CALFERON D TABLET if you are pregnant or breastfeeding. Drinking alcohol may affect calcium absorption; therefore, it is advised to limit alcohol intake while using CALFERON D TABLET. CALFERON D TABLET is safe to use in children when advised by the doctor. Do not store CALFERON D TABLET above 25°C.

Drug-Drug Interactions: CALFERON D TABLET may interact with drugs treating high cholesterol levels (cholestyramine, colestipol), antibiotics (doxycycline, ciprofloxacin, penicillin), anti-cancer drugs (estramustine), drugs treating bone loss (alendronate), thyroid hormone (levothyroxine), weight-loss drugs (orlistat), fits medicines (phenobarbital), mineral oils (paraffin), water pills (furosemide), and heart-related medicines (digitoxin).

Drug-Food Interactions: Avoid or reduce the intake of caffeine, soft drinks, and alcohol that inhibit calcium absorption.

Drug-Disease Interactions: Before using CALFERON D TABLET, consult your doctor if you have hypercalcemia, hypervitaminosis D, malabsorption syndrome, Vitamin D toxicity, heart/kidney/liver/blood vessel diseases, kidney stones, sarcoidosis, Crohn's disease, Whipple's disease, achlorhydria, low levels of bile, phosphate imbalance, diabetes, and phenylketonuria.

• Include dairy products like milk, yoghurt, cheese or milk-based custard in your diet.
• Eat daily a serving of broccoli, cabbage, bok choy, spinach and other green leafy vegetables.
• Include the best dietary sources of vitamin D, such as fish liver oils and vitamin D–fortified milk.
• Snack on calcium-rich nuts like Brazil nuts or almonds.

• Avoid or reduce the intake of caffeine, soft drinks and alcohol that inhibit the calcium absorption.
• Replace the meat with tofu or tempeh for extra calcium in your food.

• CALFERON D TABLET may interfere with cholesterol tests, hence please inform your doctor and laboratory staff that you are taking CALFERON D TABLET before undergoing blood tests.
• Clinical monitoring of serum electrolyte concentrations and cardiac function is recommended. 

Vitamin D deficiency: When a person cannot get enough Vitamin D through food and exposure to sunlight, it leads to vitamin D deficiency. It often leads to thin, brittle, or misshapen bones.

Osteoporosis: It is a bone disease that causes weak and brittle bones by decreasing bone density. 

Tetany: A disease condition due to low levels of calcium (hypocalcemia) in the body that causes cramps and spasms in the hands, feet, and larynx (voice box).

Osteomalacia/Rickets: A disease caused by softening and weakening bones in children due to inadequate vitamin D. Hypoparathyroidism: It is a disease characterized by low parathyroid hormone levels. This can cause low calcium levels and trigger tetany (muscle cramps, spasms or tremors).
