Gemitrol Capsule is used to treat low blood calcium levels. Gemitrol Capsule effectively treats various conditions caused by low calcium levels in the body, such as osteoporosis (weak and brittle bones), osteomalacia/rickets (weak bones), hypoparathyroidism (low levels of parathyroid hormone), and latent tetany (a muscle disease with low blood calcium levels). Gemitrol Capsule can also be given to pregnant, nursing, and postmenopausal women to ensure that they are getting enough calcium. Additionally, Gemitrol Capsule is used to treat hyperparathyroidism (overactive parathyroid glands) and metabolic bone disease in people with chronic kidney disease, surgery, or other conditions.
