_utma 2 years Google Analytics - A persistent cookie - remains on a computer, unless it expires or the cookie cache is cleared. It tracks visitors. Metrics associated with the Google __utma cookie include: first visit (unique visit), last visit (returning visit). This also includes Days and Visits to purchase calculations which afford ecommerce websites with data intelligence around purchasing sales funnels.
_utmb & _utmc

 _utmb – 30 mins

_utmc – End of session

Google Analytics - These cookies work in tandem to calculate visit length. Google __utmb cookie demarks the exact arrival time, then Google __utmc registers the precise exit time of the user. Because __utmb counts entrance visits, it is a session cookie, and expires at the end of the session, e.g. when the user leaves the page. A timestamp of 30 minutes must pass before Google cookie __utmc expires. Given__utmc cannot tell if a browser or website session ends. Therefore, if no new page view is recorded in 30 minutes the cookie is expired. This is a standard 'grace period' in web analytics. Ominture and WebTrends among many others follow the same procedure.
_utmz  2 years

Cookie __utmz monitors the HTTP Referrer and notes where a visitor arrived from, with the referrer siloed into type (Search engine (organic or cpc), direct, social and unaccounted). From the HTTP Referrer the __utmz Cookie also registers, what keyword generated the visit plus geolocation data. This cookie lasts six months. In tracking terms this Cookie is perhaps the most important as it will tell you about your traffic and help with conversion information such as what source / medium / keyword to attribute for a Goal Conversion.

Varithena® (polidocanol injectable foam) is a prescription medicine used to treat varicose veins caused by problems with the great saphenous vein (GSV) and other related veins in the leg's GSV system. Varithena® improves symptoms related to or caused by varicose veins, and the appearance of varicose veins.


You should not be treated with Varithena® if you are allergic to polidocanol or have clots in your blood vessels.

Severe allergic reactions have been reported in people treated with liquid forms of polidocanol and some patients have died from these reactions. Varithena® is a foam made from polidocanol. A healthcare professional will observe you for signs of allergic reactions for at least 10 minutes after you are treated with Varithena®.

Tell your doctor about all your medical conditions, including if you have:

  • Arterial disease (a disease of the blood vessels)
  • Reduced mobility
  • A history of blood clots in the veins or lungs
  • Had major surgery in the past 3 months
  • Recently had a long hospital stay
  • Become pregnant or were recently pregnant

These are not all the possible side effects of Varithena®. Tell your healthcare provider about any side effect that bothers you or that does not go away. You can also report side effects to the FDA at 1-800-FDA-1088. Varithena® is administered by your doctor. Doctors using Varithena® must be experienced in vein procedures and trained in using Varithena®.
