Have you ever noticed dark purple or blue veins twisting and bulging down your legs, looking a bit like knotted balls of string? Medical professionals call this common condition varicose veins, which affects millions of people worldwide. While some people view these twisted veins as just a cosmetic issue, others experience heavy, aching legs, itchy skin, or even painful sores.
Fortunately, modern medicine offers simple, highly effective treatments to help you find relief without major surgery. Today, we will explore one of the most successful methods available: a special medicine called a polidocanol injection. This complete guide will walk you through everything you need to know about how this treatment works, what to expect, and how to stay safe.

What is Polidocanol and How Does It Work?
Simply put, polidocanol is a liquid medicine known in the medical world as a sclerosing agent. Think of it as a specialized solution designed to gently seal off and shrink swollen, bulging veins so your body can absorb them. Under standard medical care, your doctor uses a very tiny needle to inject this medicine directly into your targeted varicose vein.
Once inside the vein, the medicine interacts directly with the inner lining of the blood vessel wall. This contact causes the inner walls to become gently irritated and stick together. Because the walls stick together, blood stops flowing through that specific damaged vein channel. Over time, your body naturally breaks down the closed-off vein tissue, absorbs it, and clears it away completely.
As your body absorbs the tissue, the unsightly, bulging vein slowly fades from view and disappears. This core process is known medically as sclerotherapy. Depending on your region, you might also hear about commercial brand names for similar formulations, such as Varithena, which help doctors deliver the treatment effectively.
What to Tell Your Doctor Before Your Treatment
Before your doctor decides whether this treatment is right for you, you must have an open and honest conversation about your medical history. Sharing accurate details helps protect your health and ensures the procedure goes smoothly. Make sure you discuss the following important points with your doctor:
- Blood Clot History: Tell your doctor if you have ever had a blood clot anywhere in your body, especially a deep vein blood clot known as Deep Vein Thrombosis (DVT).
- Allergies: Inform your doctor if you are allergic to polidocanol, any other medicines, specific foods, skin products, or medical dyes.
- Pregnancy Status: Let your doctor know right away if you are currently pregnant, planning to become pregnant, or think you might be pregnant.
- Breastfeeding: If you are currently nursing or breastfeeding your baby, sharing this information with your medical team is essential.
Important Note: Never hide your health information or medicines from your doctor. Giving a complete medical history allows your doctor to determine whether this treatment is completely safe for you.
How is This Treatment Given?
This is never a medicine you can take home or apply on your own. You must receive this injection strictly in a hospital, clinic, or specialized vein center by a trained medical doctor who specializes in vascular health. Because trained professionals handle the procedure, you can feel confident and secure about your safety.
If children or younger people ever require specialized care for vein issues, a pediatrician or pediatric specialist must be consulted to guide the decision-making process.
What if an overdose happens? Because a medical professional carefully controls and administers the dose during your visit, an accidental overdose is extremely rare. However, if you ever feel unwell during or right after your session, inform the medical staff right away. In the rare event of a severe emergency, medical teams will transfer you straight to the Emergency Department (ER). If you ever have questions about medicine safety at home, you can always contact your local poison control center (such as calling 911 in the US/Canada or 999 in the UK for emergencies).
What Side Effects Might Occur After Treatment?
Like any medical procedure, polidocanol injections can cause mild side effects. However, most people experience mild symptoms and recover very quickly without serious complications. Review the table below to understand common versus serious reactions.
| Side Effect Category | Signs and Symptoms | What You Should Do |
|---|---|---|
| Injection Site Reactions | Mild pain, redness, bruising, or slight itching right where the needle went in. | Usually fades away naturally within a few days. Follow your doctor's aftercare tips. |
| Mild Aching | A dull, tender ache running along the treated vein as it closes up. | Rest your legs and wear any compression stockings your doctor recommends. |
| Severe Allergic Reaction | Sudden skin rashes, severe itching, swollen lips, tongue, or face, and trouble breathing. | Seek emergency medical help right away (Call 911 or 999). |
| Blood Clot Signs | Sudden chest pain, shortness of breath, or one leg becoming very swollen, red, and painful. | Go to the nearest Emergency Department right away. |
This table covers the most typical reactions. If you notice any unusual symptoms or bodily changes that concern you after your appointment, never hesitate to reach out to your doctor for reassurance.
When to Call Emergency Services
If you experience sudden chest pain, severe breathing trouble, or signs of a severe allergic reaction after any medical procedure, call your local emergency number (such as 911 in North America or 999 in the UK) or go straight to the nearest emergency room without delay.
