What is the first treatment for deep vein thrombosis?

Deep vein thrombosis, or DVT, is a clot in a deep vein, often in the leg. Anticoagulant medicine reduces the blood's ability to form and extend clots while the body gradually processes the existing clot. It does not dissolve a clot instantly. A clinician considers symptoms, examination findings, bleeding risk, kidney function, pregnancy status, other medicines and whether urgent imaging is needed.

Seek same-day medical advice for a new swollen, painful, warm or discoloured limb. A GP Consultation can assess the concern and arrange appropriate testing or urgent referral. If DVT is diagnosed, Anticoagulation Management helps select the medicine, explain how to take it, and plan monitoring. Do not start, stop or double an anticoagulant without clinical advice. Tell the clinician about previous bleeding, recent procedures and every medicine or supplement you use.

Call emergency services immediately for sudden breathlessness, chest pain that worsens with breathing, coughing blood, fainting or a racing heartbeat with weakness. These symptoms can indicate that a clot has travelled to the lungs. While waiting for help, avoid driving yourself and follow the emergency operator's instructions.

Ask which anticoagulant is suitable, when it should start, what bleeding signs need urgent help, whether any usual medicines should change, and how follow-up will be arranged. Ask what activity is sensible while symptoms settle and what to do if a dose is missed.
