Cal O Tablet belongs to the class of 'Nutritional supplements', primarily used to treat low blood calcium levels. Cal O Tablet effectively treats various conditions caused by low calcium levels in the body like Vitamin D deficiency, osteoporosis (weak and brittle bones), hypoparathyroidism (a condition in which 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 exposure to sunlight.

Cal O Tablet consists of two medicines: Calcium (mineral) and Vitamin D3 (Cholecalciferol). Calcium is a mineral used to prevent or treat a calcium deficiency. It provides essential nutrients to maintain bone formation and maintenance. Vitamin D3 helps maintain blood calcium and phosphorus levels and mineralization of bone. 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. Cal O Tablet is likely safe to use. In some cases, it may cause common side effects like constipation and stomach upset. These side effects do not require medical attention and gradually resolve over time. However, you are advised to talk to a doctor if the side effects persist or worsen.

If you are allergic to Cal O Tablet or its inactive components, please inform your doctor. Please tell your doctor if you have hypercalcaemia (high calcium levels), hypervitaminosis D (high vitamin D levels), heart/kidney/liver/blood vessel diseases, kidney stones, and malabsorption syndrome (difficulty absorbing nutrition from food) before starting Cal O Tablet. Pregnant or breastfeeding women should consult their doctor before taking Cal O Tablet. This supplement should be used in children only when advised by the doctor.

It aids in calcium absorption enabling bone growth and repair. It further prevents cartilage degeneration.

Let your doctor know if you are allergic to Cal O Tablet or its inactive components. Cal O 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 to the doctor if you have any heart/kidney/liver/blood vessel diseases, kidney stones, achlorhydria (little or no stomach acid), low levels of bile, and phosphate imbalance before starting Cal O Tablet. Consult your doctor before taking Cal O Tablet if you are pregnant or breastfeeding. Drinking alcohol can affect calcium absorption; therefore, it is advised to limit the alcohol intake while using Cal O Tablet. Cal O Tablet is safe to use in children only when advised by the doctor.

Drug-Drug Interaction: Cal O Tablet may interact with drugs treating high cholesterol levels (cholestyramine, colestipol), antibiotics (doxycycline, ciprofloxacin, levofloxacin, penicillin, neomycin, and chloramphenicol), anti-cancer drugs (estramustine), drugs treating bone loss (alendronate), thyroid hormone (levothyroxine), weight-loss drugs (orlistat), fits medicines (phenobarbital), mineral oils, water pills (furosemide, etacrynic acid), and heart-related medicines (digitoxin).

Drug-Food Interaction: Avoid or reduce the intake of caffeine, soft drinks and alcohol as they might inhibit calcium absorption.

Drug-Disease Interaction: Cal O Tablet is not recommended in conditions such as hypercalcaemia, hypervitaminosis D, malabsorption syndrome, and Vitamin D toxicity. Please consult your doctor for more advice.

It is advised to timely monitor your Vitamin D levels through blood examination.

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 makes the bones weak and brittle by decreasing bone density. 

Tetany: A disease condition due to low calcium levels (hypocalcaemia) 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 of bones in children due to inadequate vitamin D. 

Hypoparathyroidism: It is a disease characterized by low levels of parathyroid hormone. This can cause low calcium levels and trigger tetany (muscle cramps, spasms or tremors).
