Cavit Syrup is used to treat children with low blood calcium levels, which occur due to conditions such as 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). This medication contains calcium carbonate and cholecalciferol, which are vital for bone formation and maintenance, as well as helping the body absorb calcium. Sometimes, it may cause mild side effects such as constipation and stomach upset. Before giving this medication, please inform your doctor if your child is allergic to any of its ingredients, is taking other medications, or has any existing medical conditions.
