How Much Time Should Be Left Between 1st and 2nd Treatment of Sclerotherapy?

It may vary among physicians, but in my practice, I recommend my patients return every two-four weeks for their sclerotherapy appointments.  It may take up to 2 weeks, perhaps occasionally longer, for results to be apparent after a sclerotherapy session, therefore you should not be treated more frequently than this. 

The timing between sclerotherapy sessions in the same areas varies among treating vein specialists. In my practice, the time between sessions is at least 3 months, provided that the entire area was completely treated in the first session. This allows enough time for the bruising to resolve and, more importantly, for the treated veins to thrombo-obliterate and heal.
