During one treatment session, up to 10 sites of each limb may be injected with the lower strength solutions.

Your doctor will ask you questions about your health and will inform you about the potential side effects of this procedure.

Your doctor will monitor you during and after the sclerotherapy for signs of hypersensitivity (redness, itching, cough) or neurological symptoms (visual disorders, migraine, tingling or numbness). He will ask you to come back for a follow up visit.

Taking other medicines
Please tell your doctor or nurse if you are taking or have recently taken any other medicines, including medicines obtained without a prescription.

Driving and using machinery
After the treatment with this injection, you may be told to wear a bandage and/or compression stockings to help reduce inflammation and pigmentation of the skin which could affect your ability to drive.


Your doctor should use ultrasound guidance in the treatment of non-visible varicose veins.

Your doctor will decide on the areas to treat and the right dose for you. The usual doses are as follows:

Adults and the elderly
Dosage varies between 0.1 and 2 ml for each injection. A maximum of 10 ml of the three lower strength injections may be used, however no more than 4 ml is used when the strongest injection is used.

Due to the limited volume of sclerosant authorised, repeated sessions of sclerotherapy may be necessary.

FIBROVEIN is not intended for use for children.

After you have been treated with FIBROVEIN, you should follow your doctor’s advice. You may be told to wear a bandage and or/compression stockings to help reduce inflammation and pigmentation of the skin.
