Will Allergies Impact Sclerotherapy?

Are you considering sclerotherapy for your varicose or spider veins but are concerned about allergic reactions? Sclerotherapy is a non-invasive and safe method for treating and reducing the look of varicose and spider veins. However, as with any other medical treatment, there are potential side effects to consider, including the possibility of an allergic reaction to sclerotherapy medication. 

Overall, complications are rare, with most patients experiencing few to no issues. If you undergo them at all, many sclerotherapy side effects are moderate and self-limited.

Sclerotherapy Complications and Side Effects 

Learn more about the different complications to help you decide if sclerotherapy treatment is right for you:

  • Allergic reactions: An allergic reaction to the sclerosant — the solution used to remove the veins — could occur, but this is rare. Let your doctor know of any existing allergies before undergoing sclerotherapy treatment.
  • Hyperpigmentation: Bruising, matting or staining could occur. Usually, hyperpigmentation is temporary and takes a few months to disappear. In rarer cases, the hyperpigmentation persists for years or is permanent. 
  • Injection site pain: Temporary tenderness or mild pain at the injection site is common, such as cramping. If pain or irritation persists, however, speak with your doctor. 
  • Blood clots: A blood clot may form near the injection site. Your doctor may need to remove it to prevent the clot from traveling further into your veins and causing more serious complications like deep vein thrombosis (DVT) or a pulmonary embolism. 
  • Inflammation: Some patients experience temporary redness, swelling or itchiness at the injection site. If redness or swelling persists, speak with your doctor. Continue to monitor for inflammation for several weeks post-treatment to be on guard for ulcers or blood clots. 
  • Air bubbles: Foam sclerotherapy could lead to tiny air bubbles becoming trapped in your bloodstream, which may then lead to issues such as headaches, migraines, nausea or coughing.  

Sclerotherapy Post-Treatment Care 

Though the cause for complications or reactions to sclerotherapy is not always known, closely following your doctor’s post-treatment care instructions is essential in reducing their likelihood. 

After completing your sclerotherapy treatment, make sure to do the following:

  • Wear medical-grade compression leggings or socks for a few weeks post-treatment.
  • Don’t consume over-the-counter anti-inflammatory medication like ibuprofen and aspirin for 48 hours after your treatment.
  • Resume light daily activities like walking but avoid rigorous exercise. 
  • Take cooler showers and avoid exposing treated veins to direct sunlight, hot baths/showers or saunas.
  • Don’t shave or apply lotion to the area of your treated veins for at least 48 hours post-treatment.
