How varicose veins form

Varicose veins are enlarged, bulging veins that most often occur in the leg's great saphenous vein (GSV) system and occur when the tiny valves inside the veins become weaker, causing blood to back up and make the veins swell.


Tiny valves help the leg veins work against gravity to push blood back to the heart.


But if valves weaken, blood can leak backwards and pool, resulting in varicose veins.

Varicose veins are usually visible and can cause uncomfortable symptoms such as swelling and achiness. Varithena treats varicose veins caused by problems with the GSV system.

Varithena® (polidocanol injectable foam) is a prescription medicine used to treat varicose veins caused by problems with the great saphenous vein (GSV) and other related veins in the leg's GSV system. Varithena® improves symptoms related to or caused by varicose veins, and the appearance of varicose veins.


You should not be treated with Varithena® if you are allergic to polidocanol or have clots in your blood vessels.

Severe allergic reactions have been reported in people treated with liquid forms of polidocanol and some patients have died from these reactions. Varithena® is a foam made from polidocanol. A healthcare professional will observe you for signs of allergic reactions for at least 10 minutes after you are treated with Varithena®.

Tell your doctor about all your medical conditions, including if you have:

  • Arterial disease (a disease of the blood vessels)
  • Reduced mobility
  • A history of blood clots in the veins or lungs
  • Had major surgery in the past 3 months
  • Recently had a long hospital stay
  • Become pregnant or were recently pregnant

The most common side effects seen with Varithena® are leg pain or discomfort, injection site bruising or pain, and potentially serious blood clots in the leg veins. These are not all the possible side effects of Varithena®. Tell your healthcare provider about any side effect that bothers you or that does not go away. You can also report side effects to the FDA at 1-800-FDA-1088. Varithena® is administered by your doctor. Doctors using Varithena® must be experienced in vein procedures and trained in using Varithena®.
