Best treatment for cold sores. works wonders for me. i always keep an extra tube at home so that i can apply at the very beginning of symptoms.

Everyone responds differently to a product. For me, Abreva did not work on my cold sores. I did not notice any fast healing. I applied the cream a couple of times a day and did not see any results. The cold sore lasted the same amount of time if I had not applied Abreva. I will probably purchase again, it did not make anything worse.

Abreva stops fever blisters and at the very least makes them smaller and disappear sooner.

Abreva is very expensive, but it does seem to get rid of cold sores more quickly than letting nature take its course. It's best to start using it immediately. The biggest problem besides the cost is the packaging. I've tried both the pump and the squeeze tube. The pump is hard to control, so you invariably get more than you really need for each application. the tube makes that easier, but be careful when you first puncture it to open it -- a big bunch squirted out the minute it opened and there's no way to put it back in. As much as this stuff costs, you don't want to waste a single dab -- and that's almost impossible to avoid. Still, it works so well I'll keep buying it until I find another product that works as well but is packaged to be more user-friendly.

On the rare occasion I get a canker sore, Abreva makes it feel better and heal quickly

I was 14 the last time I got a cold sore. That was a long time ago. Then, I was told to put alcohol on it to dry it up. That advice left me with a slight discoloration that took 20 years to fade. So when I saw some swelling on my upper lip a few days ago, I panicked. This time I read the drugstore.com reviews and saw that Abreva was what worked for most people. I assumed I'd also need to get a prescription for an antiviral medication so I checked with a pharmacist. She took me right to the Abreva and gave me her personal testimony that it works. The next day it was smaller and less angry. 3 days later, there is just a tiny scab and it's barely noticeable. I spent [$] on this stuff but it spared me 3 weeks of misery and an expensive doctor's visit. I'm happy

I am prone to fever sores. Whenever I feel the slightest tingle, I apply abreve and it prevents the eruption, providing immediate relief. Because I always apply at the very first symptoms, I can't say how it works on a full-on breakout. But thanks to this product, which I always have on hand, I haven't experienced a major eruption in years.

This is the only topical over the counter treatment that works to reduce the duration and intensity of cold sores. I put it on as soon as the area starts to "tingle" and a little red bump appears. If I put it on early enough, the cold sore is averted, but if I can't apply it early enough, the cold sore still appears, but it's duration and intensity is lessened dramatically.

I have tried everything - from over the counter items to prescriptions that cost a ton of money. Nothing works better than Abreeva. I agree that used at the very onset of a cold sore it works best. But for me, it works well even after the cold sore has become full blown. My cold sores come up right under my nose, so I have now begun to dab a little bit of Abreeva on that area about once a week - just as a preventative measure.

This stuff works... I recently started to feel a cold sore coming on and didn't have any Abreva handy. Needless to say, by the time I woke up the next morning it was there, and was too late to really do anything to help. Well within a few days I felt another "tingle" on my lip, right next to the cold sore that was already there. I literally RAN to the store and bought Abreva. I immediately applied it to my lip and continud to apply it 5+ times a day. That was 3 days ago, and it's made a huge difference. The cold sore still formed but it's TINY and is nearly healed. The cold sore I neglected to treat early is still there, over a week later. I'll be keeping a tube of this stuff handy at all times from now on. IT WORKS!!
