Have tried prescription valtrex (valacyclovir) pills and ointment at the first signs. still have fever blisters twice a month or more . any preventative options.?

May need suppression: If you are having outbreaks twice a month despite using Valtrex (valacyclovir) pills and ointment when you first feel an outbreak starting, you probably need to take Valtrex (valacyclovir) or another pill on a daily basis to try and suppress the outbreaks. Patients can take Valtrex (valacyclovir) pills for up to a year every day. After 1 year you can decide with your doctor if you need to continue or if you can stop. Talk to your doctor.

Fever Blisters: Regular use of Valtrex might be helpful. To prevent cold sores from occurring wash hands often. Maintain a healthful lifestyle (regular exercise, nutritious diet, adequate sleep, keeping stress at bay). Keep lips well moisturized & apply sun screen to the areas that your cold sores normally pop up. Talk with your physician about supplementing with Lysine.
