When and How to Take Polidocanol

General considerations to keep in mind during treatment with polidocanol include the following:
  • Your healthcare provider will inject this medication directly into the affected veins.
  • There is a limit to how much polidocanol can be used per treatment; therefore, there is a limit to how many veins can be treated in a session. For people with extensive spider or reticular veins, more than one treatment session may be necessary.
  • Right after the injection, compression should be used, typically in the form of compression stockings or bandages. This should be continued for two to seven days (depending on the severity of the veins), or perhaps longer in more severe cases. Compression is necessary to reduce the risk of deep vein thrombosis (DVT).
  • Ask your healthcare provider if you will need thigh-high or knee-high compression stockings or support hose.
  • It is best if you can walk for 15 to 20 minutes after the treatment session and daily for a few days thereafter.
  • For two to three days after treatment, avoid heavy exercise, sunbathing, long plane flights, and hot baths or saunas.
  • Make sure your healthcare provider is adequately qualified for this type of treatment; careless or improper injection technique can lead to dangerous complications.

Dosing Information

The specific dosage your healthcare provider will use depends on whether spider veins or reticular veins are being treated (see Polidocanol Dosage for more information).

Drug Interactions

Polidocanol is unlikely to interact with other medicines (see Drug Interactions With Polidocanol).
