Women are turning to Viagra for an unexpected reason: to relieve painfully cold hands and feet caused by a circulation disorder known as Raynaud’s phenomenon. The medication, widely recognised for treating erectile dysfunction in men, contains sildenafil, a drug that relaxes blood vessels and improves blood flow. Doctors have explored its use in women whose blood vessels narrow excessively, restricting circulation to their fingers and toes. Raynaud’s phenomenon can cause fingers and toes to turn white or blue, become numb, tingle or feel intensely painful when exposed to cold temperatures or stress. The condition is more common in women than men. Sildenafil works by widening blood vessels, potentially helping restore circulation and reduce the frequency or duration of Raynaud’s attacks in some patients. However, its benefits can be modest, and it does not work equally well for everyone. Although Viagra is not usually the first treatment for Raynaud’s, doctors may consider sildenafil for patients whose symptoms persist despite other treatments. Options can include keeping warm and taking medicines that help relax blood vessels. The treatment also carries risks, including headaches, dizziness and dangerously low blood pressure, particularly when combined with certain medications. Women should not take Viagra for this condition without medical supervision. The unusual use highlights how a drug best known for its role in sexual health can also have applications in treating circulation problems.
