About 35 yrs ago I started getting cold sores and they were horrible. It caused my lip to swell and become distorted and would last about 2-3 wks. I read an article about sun uv light triggering it and decided to get lip balm w/an spf of 45 (hawaiian tropic) I put that on my lips at least 30 min before i leave the house to get absorbed in and might reapply a few times a day. I now only get cold sores maybe once every 5-6 yrs. Also, if my lip itches, I never scratch it b/c that also triggers a cold sore (trauma to the lip) hope that helps.
Always very helpful, thank you!
It’s hard to avoid the sun living in the Deep South, but I always try to avoid overexposure to the sun.
I’m on 500mg/day of Famciclovir. I wondered if switching to Valacyclovir would be helpful, as well as upping to 1000mg/day.
I started on 250 acyclovir and was having less sever breakouts but same frequency. Then changed to famvir 500mg/day and didn’t have an outbreak for 18 months. But when I did, it was more severe. And last was 5 months between outbreaks, again more severe but I haven’t been on the end that long I guess. I’d like a virologist opinion.
Yes, that can help, though the only way to know for you is to try it. While sun is a pretty big trigger for a lot of people with hsv1 orally, for some, it can be general sun exposure, and others it's just sun on their lips.
Since sunburn is a trigger for you, it would seem that general sun exposure is more the trigger, unless you just got the sunburn on your lips or face. You should use sunscreen while you are out in the sun (always a good idea anyway), or maybe a hat with a brim large enough to protect your face. Definitely get some lip balm with sunscreen in it.
What antiviral are you on? You might try upping the dose if you know you're going to be out in the sun. If you take 500 mg of Valtrex, for example, try taking 1000 mg the day before, the day of, and the day after.
I hope that helps!
