Know Your Triggers.
One way to manage your recurrent cold sores is to pay extra attention to things that might trigger an outbreak. It's different for everyone. You might get a cold sore from spending too much time in the sun or simply because you're stressed. It's helpful to write down these events—or triggers—so you can track them. You should also discuss your triggers with your doctor.

Some Common Cold Sore Triggers Are:

  • Exposure to weather conditions like extreme sunlight (e.g., being in the sun too long) or extreme cold (e.g., being in a cold climate for too long)
  • Stress
  • Menstruation and pregnancy (Sorry ladies, hormonal changes can trigger an outbreak.)
  • Depression
  • Injury to skin on lips/mouth (This one's for the guys: Cut yourself shaving? It may trigger an outbreak.)
In the end, only you know your body best. If you've noticed a trend other than those listed above, they could be a part of what's triggering or causing a cold sore outbreak. So be sure to tell your doctor that you've had a cold sore. And ask him or her about ZOVIRAX® (acyclovir) Cream 5%—having a tube handy may help you be armed and ready for your next cold sore outbreak.
