Sclerotherapy is a minimally invasive medical procedure used to treat spider veins and small varicose veins, primarily on the legs. A solution, known as a sclerosant, is injected directly into the affected vein, irritating its lining. This causes the vein to swell, collapse, and eventually fade as it is reabsorbed by the body. Although the procedure is quick and performed in an office setting, proper preparation is necessary to ensure the best results and a smooth experience.
Medical Disclosures and Medication Management
Before scheduling sclerotherapy, a comprehensive discussion with the clinician about your medical history and current medications is necessary. You must disclose pre-existing conditions, such as a history of blood clots, heart conditions, or allergies to sclerosant agents or local anesthetics. Pregnancy or breastfeeding status must also be disclosed, as these are typically reasons to postpone treatment.
Provide a list of all medications, including over-the-counter drugs, herbal supplements, and vitamins, as some increase the risk of bruising or bleeding. Non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen, naproxen, and aspirin, as well as prescribed blood thinners, must often be stopped several days prior. These medications interfere with the body’s normal clotting function, and stopping them reduces the chance of excessive bruising.
The typical restriction period for NSAIDs is often between five and ten days before the appointment. Supplements such as Vitamin E, fish oil, and iron are also restricted for about a week due to their potential to increase bleeding risk. Patients must only discontinue prescribed medications after consulting both the sclerotherapy clinician and the prescribing doctor. Acetaminophen is generally safe for mild aches and pains leading up to the treatment.
Physical Preparation on the Day of Treatment
Physical preparation focuses on ensuring the skin is clean and accessible for the procedure. On the day of the appointment, avoid applying any lotions, oils, or creams to the treatment area. These products leave a residue that interferes with the antiseptic solution and prevents bandages or compression stockings from adhering properly afterward.
If hair removal is desired, it should be done at least one day prior to the appointment. Shaving or using a depilatory cream on the day of the procedure is discouraged because it can cause minor skin irritation or cuts, increasing the chance of infection or discomfort. Wear loose-fitting, comfortable clothing, such as shorts or a skirt, to the clinic. This allows easy access to the treatment sites and accommodates post-procedure bandages or bulky compression garments.
Eat a light meal before arriving for your appointment and ensure you are well-hydrated. Eating helps stabilize blood sugar levels, minimizing the likelihood of feeling lightheaded or dizzy during or immediately after the procedure. Hydration also supports healthy circulation, which aids the post-treatment healing process.
Logistical Planning and Required Supplies
The acquisition of prescribed compression garments is a key logistical requirement. Compression stockings or hose must be purchased prior to the appointment. These are typically medical-grade, often rated 20–30 mmHg, and must be brought to the clinic on the day of the procedure.
The compression hose will be applied immediately after the injections to maintain pressure on the treated veins. This helps them collapse and minimizes bruising and swelling. Try on the stockings beforehand to ensure the correct fit and comfort, as they must be worn continuously for a specific period after treatment. Patients should confirm the exact appointment time and plan for the duration, which can range from 15 minutes to an hour.
Arrangements for transportation home are necessary following the procedure. Clinics may discourage or prohibit driving immediately afterward, especially if a mild sedative was administered or if the patient is prone to dizziness. Planning for a 20- to 30-minute walk shortly after the treatment is also encouraged to promote circulation and reduce the risk of blood clots.
