Does sclerotherapy treat spider veins?

Spider veins are small visible vessels, often appearing as red, blue, or purple lines or branching groups. During sclerotherapy, a clinician places an injectable solution into selected veins. The vessel then closes and is gradually reabsorbed by the body. Nearby circulation continues through other healthy vessels.

Not every visible vein is suitable for the same approach. The clinician may assess vein size, location, symptoms, skin condition, and circulation before recommending treatment. Larger or deeper veins may need a different evaluation.

Choose a qualified clinician who can examine the veins and discuss alternatives. Share your medical history, medicines, previous vein procedures, allergies, pregnancy status, and any history of clotting or circulation problems. Ask what clothing, walking, compression, and skin care will be advised afterward.

Follow the aftercare plan carefully and attend any review appointment. Treated areas can change gradually, so avoid judging the result immediately after the injection.

Have new painful, swollen, warm, or suddenly prominent veins assessed, particularly if one leg changes quickly. After treatment, seek urgent medical advice for severe leg swelling, chest pain, sudden breathlessness, or fainting. Contact the clinic for worsening pain, spreading redness, significant skin change, or concerns about the injection site.

Ask whether the visible vessels are spider veins, whether circulation testing is needed, and which treatment fits their size and location. Ask about expected fading, possible skin changes, compression or walking instructions, and when further treatment might be considered.
