Cold sore with lip injections? What do I do?

You just have to wait it out, but no intervention for the lip injections needs to be done. I hope this helps. 

This should not affect the filler. You would benefit from some anti-viral medication which your doctor can prescribe.   

I recommend following up with your Doctor. If necessary, this can be treated with anti-viral medication. I hope this helps. 

Treat the cold sore as you would if you did not have lip fillers. 3 to 4 months suggests the filler will be harmoniously infiltrated through out your lip tissues so no harm should occur.

Although reactivation of certain viruses are quite possible after physical trauma associated with filler injections, these occur usually very soon after the injection. If your filler was injected 3-4 months ago, the expression of virus in your case is most likely a coincidental issue. If it happens you start oral treatment as soon as possible; if you are at the blister stage, the course will be only partially affected by the medications. The topical antiviral at this stage are of no use for many reasons. I would also consider taking oral medication for 2-3 doses as a profilaxis after your next injections. These antiviral medications are very safe and can be taken in very large doses over extended period of time without any side effects, e.g.. in immunocompromised patients after organ transplant. Good luck!

Are usually ask my patients if they break out in cold sores around the mouth prior to doing their lip injection. If there is a positive history of this, are usually treat them with Valtrex or Famvir. See your doctor and see if he or  she can prescribe you this medication.

Having a cold sore on the lip must be addressed with antiviral medication. A systemic medication should be taken combined with a local application of an ointment. You should follow up with your treating physician for these prescriptions. It should not affect your lips poorly as long as it's being treated.. Good luck from New York City
