What do i do to get rid of a cold sore/fever blister before school?

You Can't: Cold sores are caused by the herpes simplex i virus and usually take 10-14 days to resolve. Prescriptions meds (from dentist or md) can help reduce the discomfort & lessen the rate of recurrance but once the sore is present it has to run it's course. Meds can help it feel better but not get rid of it. The virus lives in the nerves and stays there forever once you get it & most people have it.

Herpes Simplex: See your doctor for a prescription med. Herpes simplex 1 or hsv 1also known as oral herpes. It is different from genital herpes which is hsv 2 . . Medication can decrease the pain related to an outbreak and can shorten healing time. They can also decrease the total number of outbreaks. Drugs including famvir, zovirax, and Valtrex (valacyclovir) are among the drugs used to treat the symptoms of herpes.
