How many days before a microneedling procedure should I take valtrex?

Hi @caroleliz! I recommend taking Valtrex the day before your treatment to reduce the possibility of a cold sore around the oral area. Best of luck to you!

It is recommended to begin taking Valtrex 3 days prior to microneedling to reduce the possibility of a cold sore flare up around the mouth, and it is important to continue taking Valtrex as directed by your provider post procedure.

If you are prone to cold sores, taking Valtrex 1-2 days or an anti-viral may help prevent cold sores around the lips. In our experience we haven't noticed that our patients have been more prone to developing cold sores (herpes simplex) from the microneedling procedure. I would not recommend doing the procedure with active lesions. I hope this was helpful, thank you.
