Obcal Sachet 1 gm belongs to the class of 'Vitamins', primarily used to treat low blood calcium levels. Obcal Sachet 1 gm effectively treats various conditions 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.

Obcal Sachet 1 gm contains 'Cholecalciferol' a form of vitamin-D. It acts by promoting the absorption of calcium, phosphates and Vitamin A from different organs and helps in maintaining overall health.

Take Obcal Sachet 1 gm as advised. Your physician will decide the dosage based on your medical condition. Obcal Sachet 1 gm is likely safe to consume. In some cases, it may cause side effects like constipation, increased blood calcium levels, increased calcium levels in urine, vomiting, nausea. These side effects do not require medical attention and gradually resolve over time. If these side effects persist, please consult your physician immediately.

Chewable or dissolving tablets may contain sugar or aspartame, hence caution should be taken in diabetes and phenylketonuria (increased levels of an amino acid called phenylalanine).

Obcal Sachet 1 gm is used to treat low blood calcium levels. It effectively treats various conditions in the body like Vitamin D deficiency, osteoporosis, hypoparathyroidism, latent tetany and rickets or osteomalacia. Obcal Sachet 1 gm contains Cholecalciferol (Vitamin D3). Cholecalciferol is a steroid hormone produced in the skin when exposed to ultraviolet light or obtained from food sources. It is a provitamin that is converted into vitamin after intake.  It helps maintain blood calcium and phosphorus levels and mineralization of bone. Obcal Sachet 1 gm is also used in the treatment of familial hypophosphatemia (a group of rare inherited disorders characterized by impaired kidney conservation of phosphate and in some cases, altered vitamin D metabolism).

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 weakens 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).
