How soon after Juvederm injections do cold sores normally form?

Question

Will Valtrex completely stop them from forming after treatment? Or is it just to lessen the chance of a break out?

Jason Emer, MD · Answer

I have never had any patient get sores after Juvederm, but have seen patients where a blood vessel has been damaged and this caused skin sores.  If you are talking about a herpes outbreak and are concerned, you can take valtrex prior to lip injections to prevent it from occurring.  Best, Dr. Emer.

Cold sores may form 1-2 days after filler injections around the mouth, and you may start to feel the onset a few hours after injections. To minimize the risk for cold sores, you may take Valtrex prophalactically as directed by your physician starting one day prior to the procedure.

Hello Klk93,Cold sores can develop within a few days up to a few weeks after injections around the lips.  The use of Valtrex can minimize the risk but not completely eliminate it.  If you do develop a cold sore when taking Valtrex then you should be switched to a different antiviral medication such as Zovirax.  I hope this helps and good luck.

Dan Landmann, MD · Answer

Cold sores typically do not form after Juvederm injections. But, in patients that have a history of cold sores, doctors often prescribe Valtrex, because it will lessen the likelyhood of developing a cold sore and shorten the duration of having the cold sore. I was at a cosmetic surgery conference this past year and raised the question, "what do doctors typically do for prophylaxis against cold sores" and there was no consistent answer - some doctors prescribe Valtrex before, some the day of and some for several days after. The bottom line though, is that if you start to feel a cold sore develop, and you use Valtrex as soon as possible, it should decrease the severity and longevity of the cold sore.

Juvederm is a great injection and if you have a history of cold sores I would recommend you taking Valtrex prophylactically to prevent cold sores.

Alim R. Devani, MD, FRCPC · Answer

If you have a history of cold sores, you need to tell your provider especially if you are getting fillers into your lips. Valtrex is used for prevention and decreases the risk of an outbreak but doesn't guarantee you won't still get a cold sore. Cold sores can start as soon as 1-2 days post injection. For the best results please consult a board certified
dermatologist with experience with dermal filler and hyaluronic acid cosmetic
injections.

Grant Stevens, MD · Answer

If you have a history of cold sores, inform your medical provider before treatment so he/she may start you on a prophylactic course of anti-viral medication. Valtrex is a particular type of anti-viral medication commonly used, and when used as prescribed, it will significantly lessen the chance of an outbreak. If a breakout has already occurred, Valtrex will decrease the duration of symptoms.

If you are prone to cold sores, be sure to tell your injector so you may be started on anti-viral medications.  You may not always develop the cold sores, but the medications will lessen the liklihood and/or reduce the severity.

F. Victor Rueckl, MD (in memoriam) · Answer

If you are prone to cold sores you should always take an antiviral before lip fillers, or before trips to the dentist. While it won't guarantee you won't have an outbreak, there is a much lower chance of it occurring. Typically people will get a cold sore 1-2 days after injection if they don't take an antiviral and are prone to cold sores. "This answer has been solicited without seeing this patient and cannot

Dearklk93, Valtrex will help reduce the risk of cold sores after your Juvederm treatment. Typically most patients with a history of  cold sores will be started on an anti-viral medication prior to the injections. Valtrex is a common anti-viral medication for this usage. Valtrex will help decrease the risk of a breakout. Best regards, Michael V. Elam, M.D.
