Venous thrombosis can be treated with anticoagulant drugs, NSAIDs, and other medications. 1. Anticoagulant drugs: Usually warfarin, heparin, rivaroxaban tablets etc. are taken orally under doctor’s supervision. The purpose of drug treatment is to prevent and control blood clots, and it is also the basic method of treating venous thrombosis. If the thrombus still remains after the medication, it is recommended to switch to Sulodexide, i.e. Vesicin, for continuous low-dose anticoagulation. 2. Non-steroidal anti-inflammatory drugs: Commonly used drugs are aspirin, meloxicam, diclofenac, ibuprofen, etc. The drug has anti-inflammatory and analgesic effects, and aspirin can inhibit platelet aggregation, which reduces the probability of recurrence of venous thrombosis. 3. Other drugs: according to the symptoms caused by venous thrombosis, you can also take the grass rhinoceros infusion tablets, horse chestnut seed extract tablets and other swelling treatment; take vitamin C to improve the elasticity of blood vessels and so on. In addition to the above treatments, patients with venous thrombosis also need compression therapy (e.g. wearing compression stockings, etc.), which is aimed at relieving varicose veins and promoting localized reflux, and secondly, elevation of the affected side, which promotes fluid reflux and reduces localized swelling. In acute cases, thrombolytic therapy can be used, and in severe cases, surgical treatment should also be given. It is recommended to go to the hospital and ask yourself about the situation, listen to the doctor’s advice to choose drugs and treatment methods, drugs should be applied under the guidance of the doctor.
