Hi ! Hi there, Thank you for posting your question. I will do my best to help you I have tried to understand your query to my best. Venous Thrombosis is not condition to be neglected. If diagnosed as in your case as mentioned ,do take complete treatment as advised by the treating Consultant. Venous Thrombosis is a condition in which a blood clot (thrombus) forms in one or more of the deep veins in your body, usually in your legs. The blood clot that has formed in your vein can break loose, travel through your bloodstream and lodge in your lungs, blocking blood flow (pulmonary embolism). Hence ,to prevent this complication which is serious , you will need to take a medicine called an anticoagulant which was prescribed to you as per Information provided (Injection Grefac) under medical supervision . Role of ANTICOAGULANT : -Anticoagulant medicines prevent a blood clot from getting bigger - help to stop part of the blood clot from breaking off and becoming lodged in another part of your bloodstream (prevents embolism) -Two different types of anticoagulants are used - (1) Heparin –Available in two forms –Standard (unfractioned)Heparin and Low molecular weight Heparin (LMWH) (2) Warfarin -Heparin is usually prescribed first, because it works immediately to prevent further clotting -After this initial treatment you may also need to take warfarin to prevent another blood clot forming ( as per Medical consultant advise if required)) -Standard (unfractioned) heparin can be given as an intravenous injection -(this must be done in hospital under supervision) -LMWH is usually given as a subcutaneous injection -Warfarin is taken as a tablet. You may need to take it after an initial heparin treatment to prevent further blood clots occurring Discontinuing treatment for the diagnosed illness -Venous thrombosis is not advised . My sincere advise to you is to consult the Treating Physician immediately or at earliest without neglecting . Prevention is better than cure.
