I started feeling a cold sore coming on yesterday so I ran out and bought Abreva along with Heprecin L ChapStick. I used both last night and this morning all I see is a tiny red spot instead of that terrible sore. It hardly even made it to the surface before I was able to stop it. It is great stuff. If you use it right when you feel the tingling, you can stop it in its tracks.

This is a miracle drug. I started using the product after the suggested "tingle" stage once I already had full blown blisters. By the end of the day my cold sore had shrunk and it was already beginning to heal. It is expensive for the little tube they provide you, but you use so little of the medication that it goes quite a long way. Definitely my recommendation for an over-the-counter cold sore treatment.

Having used prescriptions creams and pills for my lip cold sores for years, I've found Abreva better than the popular prescription - Zovirax. Generally, my cold sores lasted 7-10 days. With Abreva, I've completely stopped cold sores from erupting when applied at the first 'tingle'. Sometimes, the cold sore still erupts but the time is cut down to 3-5 days. I recommend this product to anyone who suffers from cold sores.

I started to get a cold sore on Monday. I started treating the sore on Tuesday with Abreva. The blister was pretty large and swollen by that time, the entire upper half portion of my lip was a large bump. Also, very painful. The Abreva really didn't help too much with the pain except for the second or two after application, but MY SORE IS ALMOST GONE and it's only Wednesday! Only one day after and it's not hurting nearly as bad, the swelling is almost completely gone and it's starting to dry up. It will be gone by the weekend I'm sure. I can't believe it; it is a miracle. Maybe other people who aren't satisfied with this product have much worse/stubborn cases of cold sores. I rarely get them so I guess I'm really not the person to ask, but I am thrilled with the results.

I use Abreva in conjunction with Herpecin-L lip balm. I use the lip balm all the time to keep my lips from getting dry and to help prevent cold sores. I use the Abreva when I feel the dreaded tingle. I haven't had a cold sore since using these products. I highly recommend both.

I've had cold sores since the sixth grade about once or twice a month. Nothing ever worked. But in the last decade, my breakouts have dwindled to once every other year! I think it's because of my almost obsessive use of SPF lip balm and vitamin C. The sun is a HUGE trigger, so slather on the lip balm several times a day that contains at least SPF 15. Also, you're more prone to breakouts if your immune system is less than 100%....that's where the vitamin C comes in. And then, this product...Abreva. I've used everything on the market and this is the only thing that halts that horrid tingling sensation. It's too bad it didn't work for some people. But it does wonders for me. Good luck to my fellow cold sore sufferers, and let's hope for a permanent cure within our lifetime. Until then, try the SPF lip balm, vitamin C, and Abreva. :)

What a WASTE of money! For something that cost as much as it did, I expected it to actually work!!!! I followed the directions closely and it just did not help at all! It actually made my cold sore worse! I looked horrible! And I deal with people face to face at my job. I tried my best to hide away and have another co-worker do my job! I would never recommend this super tiny tube of white goo to anyone! Save your money and buy the cheaper remedies, such as Carmex for cold sores. Plain and simple: waste of time and money.

I've tried other over the counter cold sore medications, and I have to say this one is the best! If you can use it right away, it prevents the sore from erupting. Use it every time you get a cold sore, and they come back less virulent, even if you don't catch them right away. It's expensive, but a little goes a long way. No need to slather it on thick. A little dab rubbed in thoroughly works just as well as a huge glob. One tube lasts me through several breakouts, and I had my last tube over a year. Works just as well as acyclovir for me.

I have tried so many things for my lips and this one really works well for me. I notice that some reviewers do not care for this product, but if you suffer with canker sores it is worth the try. Leave it on a little thick and it will eventually dry the sore. It worked for me!

This product is very expensive and is packaged to look like a prescription medication so you think "Wow, this must be good stuff and really work". Well guess what, it didn't work for me at ALL. I might as well have been rubbing mayonnaise on my lip. Another annoying thing: they put it in this big package but when you open the box the tube is like 1 inch long. For the price, they could have given you more! This product is a rip off, avoid it.
