Parnacal-OD Tablet 10's belongs to the class of 'nutritional supplements', primarily used to treat low blood calcium levels. Parnacal-OD Tablet 10's 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). 

Parnacal-OD Tablet 10's consists of two drugs: Calcium orotate (mineral) and Vitamin D3 (Cholecalciferol). Calcium orotate is a mineral used to prevent or treat calcium deficiency. It provides essential nutrients necessary for bone formation and maintenance. Vitamin D3 helps maintain blood calcium and phosphorus levels and mineralization of bone. It aids in calcium absorption enabling bone growth and repair. It further prevents cartilage degeneration.

Use Parnacal-OD Tablet 10's as directed by your doctor. Parnacal-OD Tablet 10's is likely safe to use. In some cases, it may cause common side effects like constipation and stomach upset.

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 disorder that makes the bones weak and brittle by decreasing bone density. 

Tetany: It is a condition occurring due to low calcium levels (hypocalcaemia) in the body that causes cramps and spasms in the hands, feet, and larynx (voice box).

Osteomalacia/Rickets: It is 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).
