What is Asclera?

Asclera (polidocanol) Injection is a prescription medication approved by the FDA for the treatment of uncomplicated spider veins (≤ 1 mm in diameter) and reticular (small varicose) veins (1-3 mm in diameter) in the lower extremities. It's used in a treatment called sclerotherapy, during which Asclera is injected into an affected vein, causing it to seal shut, eventually reabsorb into the body, and fade from view over time.

The number of required treatments and outcomes of sclerotherapy vary from person to person, but typical treatment for spider and reticular (small varicose) veins is 1 to 3 injections. Sessions are usually spaced 1 to 2 apart.

What Should I Expect During the Treatment?

  • Each session typically lasts 15 to 45 minutes
  • Antiseptic will be used to clean the treatment area
  • A very fine needle will be used to inject Asclera into the treated veins
  • A slight stinging may accompany each injection

Because every patient is different, each treatment and its results will vary. Factors include varicose vein severity, disease progression, skin tone, and extent of recommended treatments.

What Potential Changes Are Common After Treatment?

  • Bruising
  • Raised red areas
  • Small skin sores
  • Darkened skin in the form of lines or spots
  • Multiple tiny red blood vessels

These side effects usually go away within a few days to several weeks. Some side effects may take months or years to resolve.
