A combination of two drugs known as Thermothur Ointment is used to treat superficial thrombophlebitis, which is the swelling or inflammation of a vein caused by a blood clot. Thrombophilia is an inflammatory disorder in which a blood clot forms and blocks one or more veins, usually in the legs. Thromothur Ointment, a combination of drugs, is used to treat thrombophlebitis near the skin's surface. It dissolves clots while also relieving pain and inflammation by increasing blood flow. This helps the healing process as a whole. Use it exactly as directed by your doctor for the best results. In most cases, the illness improves on its own.
