Warfarin necrosis

Warfarin necrosis is a condition that occurs when the blood-thinning medication warfarin causes the skin to die. This condition is rare and typically occurs within the first few days of starting warfarin therapy.

Symptoms

The symptoms of warfarin necrosis can vary, but they often include:

• Pain and swelling in the affected area
• Skin discoloration, which may be red, purple, or black
• Blisters or sores on the skin
• Skin that feels warm or hot to the touch

Causes

Warfarin necrosis is caused by the medication warfarin, which is used to prevent blood clots. In some cases, warfarin can cause an imbalance in the blood clotting process, leading to the formation of clots in the small blood vessels of the skin. This can cause the skin to die.

Diagnosis

Warfarin necrosis is typically diagnosed based on the patient's symptoms and medical history. The doctor may also order blood tests to check for an imbalance in the blood clotting process.

Treatment

The treatment for warfarin necrosis typically involves stopping the warfarin medication and starting a different type of blood thinner. In severe cases, surgery may be needed to remove the dead skin.

Prevention

To prevent warfarin necrosis, it's important to take warfarin exactly as prescribed by your doctor. Regular blood tests can also help monitor the effectiveness of the medication and detect any potential problems early.
