Is it normal for a doctor to prescribe me Neoparin for a leg fracture?

The use of Neoparin injections is indicated for the prevention of venous thromboembolism in the case of prolonged immobilization, e.g. after a fracture with the use of a plaster cast. Neoparin is used all the time when the gypsum is put on, and sometimes even longer. The need for further prophylaxis depends on the individual risk of thrombosis, fracture status and the patient's ability to undertake physical activity.
