I woke up with a cold sore yesterday morning without any signs before. I was already pretty big so I took 1500mg of Famciclovir. My prescription came with 21 250mg tables so I took 6 of these although my doctor suggested that I take 1 tabled every 8 hours... I didn't follow that because I did research and the dosage for cold sores is usually a single intake of 1500mg. Unfortunately, my cold sore is the same and it does not look like it is healing any faster. I am wondering if I should take another 1500mg? or follow the 250mg every eight hours for the rest of the week?
Any advice is greatly appreciated. Thanks!
