Does abreva really work to heal cold sores? I feel like It did the opposite and caused my cold sore to spread

Not effective: Docosanol (Abreva) slightly inhibits the virus in the lab, but not effective in treating oral herpes. So it's not quite quackery, but comes close. But it shouldn't make an outbreak worse, unless maybe you're allergic and it caused increased redness, itching, etc. Ask your doctor about a prescription for valacyclovir: 2 g twice, 12 hr apart as soon as an outbreak starts, is very effective.

I keep getting cold sores back to back I saw one coming up so I used the abreva it went down n couple days later it came bk up what is causing that?

Herpes virus: Cold sores are viral infections and the virus "hides" in the nerves close to where the ulcer is. That is why they tend to come back in the same location. The best treatment involves antiviral meds. There is a topical application called viroxin that kills the virus and very effective at the early signs. However if your immune system is low, they come right back. Read more
