It is very important that your doctor check your progress at regular visits to see if the medicine is working properly and to decide if you should continue to receive it. Blood tests will be needed to check for unwanted effects.

This medicine may cause serious allergic reactions, including anaphylaxis, which can be life-threatening and requires immediate medical attention. Call your doctor or nurse right away if you have a rash, itching, hoarseness, trouble with breathing or swallowing, or any swelling of your hands, face, or mouth after receiving this medicine.

Wear compression stockings or a support hose on the treated leg(s) continuously for 2 to 3 days or for 5 to 7 days, and for 2 to 3 weeks during daytime. This would help prevent formation of blood clots.

It is recommended that you walk for 10 to 20 minutes for Varithena® or 15 to 20 minutes for Asclera® immediately after the treatment and daily for the next few days, unless your doctor tells you otherwise.

This medicine may cause a permanent depression (necrosis) under the skin at the injection site. Contact your doctor right away if you notice any of these side effects at the injection site: depressed or indented skin, blue-green to black skin discoloration, or pain, redness, or sloughing (peeling) of the skin.

This medicine may increase your risk of having blood clots in the brain, heart, blood vessels, or lungs, which may lead to stroke, heart attack, deep vein thrombosis, or pulmonary embolism. Check with your doctor right away if you have difficulty with speaking, slow speech, inability to speak, inability to move the arms, legs, or facial muscles, chest pain or discomfort, pain or discomfort in the arms, jaw, back, or neck, pain, redness, or swelling in the arm or leg, trouble breathing, or dizziness or lightheadedness.

Avoid heavy exercise, sunbathing, long plane flights, and hot baths or saunas for 2 to 3 days for Asclera® or 1 week for Varithena® after you receive this medicine. Do not spend long periods of time being inactive (including long car rides) for 1 month after Varithena® treatment.
