Devit-3 is a sterile intramuscular (I.M.) injectable ampoule containing Vitamin D3 at a concentration of 300,000 IU/ml. This prescription medication is used to treat or prevent Vitamin D deficiency when oral supplementation is not suitable. This is a prescription-only medication that must be administered by a healthcare professional via intramuscular injection. Each box contains 1 sterile ampoule. Vitamin D3 (cholecalciferol) helps regulate calcium absorption and bone metabolism. The high concentration formulation allows for less frequent dosing compared to daily oral supplements.
