Typical prescriptive anti-viral oral medication dosage is 500mg twice per day for 5-7 days, starting 2 days prior to getting a lip tattoo. This is an important precaution to take because the herpes simplex type 1 virus (HSV-1) that causes fevers blisters (aka cold sores) never leaves the body and the outbreaks are extremely contagious.

Please note that the herpes simplex type 2 (HSV-2) can cause these symptoms as well and that sometimes an outbreak can still occur while taking anti-virals. While there is no telling what will trigger an outbreak or when, they are typically triggered by illness, stress, or trauma (including invasive work) on the face.
