Recommended, non prescription brand for treating chronic venous insufficiency symptoms 1

How does Daflon work?

wave icon

Venoactive treatments, like Daflon, are designed to help improve our leg vein health by strengthening the tone of our veins, which continue to weaken as chronic venous insufficiency progresses.

Daflon has a dual mechanism of action; its venous anti-inflammatory action venoprotective reduces pain and swelling; it also protects the capillaries or tiny blood vessels to improve microcirculation and venous tone for better vein health and relief of symptoms such as leg pain, and swelling. 2

Tackle leg pain from the inside

Daflon is a clinically proven, effective and convenient oral treatment derived from immature oranges and specially formulated for maximum absorption. 2

This improved absorption means Daflon can get to the root of the problem and effectively treat veins from the inside, improving the tone of veins, potentially protecting against disease progression and providing relief from heavy, painful leg symptoms. 2

Clinical Studies have shown that Daflon can reduce leg pain and the sensations of heaviness and swelling by up to 50% after only one month of use. These figures were even higher after two months of treatment.

To benefit from your Daflon treatment, you should take your medication as recommended. Be sure to monitor your condition closely and speak with a health care professional if you have any concerns.

Daflon. Naturally sourced, scientifically prepared.

The active ingredient in Daflon is a micronized purified flavonoid fraction (MPFF)6 containing 90% diosmin and 10% other flavonoids expressed as hesperidin.

Daflon’s flavonoids are extracted from immature oranges that are rich in these naturally occurring plant chemicals. The compounds undergo a process of purification and refinement where the particles are made to collide with each other at high speeds (micronization), reducing them to tiny particles, less than 2 μm in size (micronized). These smaller particles are absorbed twice as easily by the body and are a key ingredient of Daflon’s success as a treatment for improving vein health and tone in Chronic Venous Insufficiency and Hemorrhoids. 6
