What is Varithena? Because no two patients (or two veins!) are the same, we offer a variety of minimally-invasive varicose vein treatments. One of these involves Varithena foam. Varithena treatment is a safe, effective, and FDA-approved technique that can improve painful or unpleasant vein symptoms.We can perform Varithena treatment at any of our 90 nationwide offices. No hospital stay is involved because it is a short, outpatient procedure. That’s great news for busy people, since it is easy to return to normal activities. After a Varithena procedure, many of our patients wonder why they didn’t seek treatment sooner!
