"I kissed a girl with cold sores when I was 17. I get cold sores on my lip whenever I am sick or very stressed. It happens more during the winter months. It took 18 months from my contamination until my 1st outbreak. I had outbreaks once per year for 3 years, then twice per year for 3 years. Now that I am 35 I get 4 outbreaks per year. I take 2 grams on Valtrax when I first feel tingly then 1 gram the next day (24 hours). This totally prevents my outbreaks! Valtrax works great! Also, do not share food, drinks, or kiss anyone while you have a cold sore. It is very contagious! Keep your kids safe."

"I have been getting cold sores since I was a little girl the doctor always told me that it was virus in my system that I had to deal with it but last month I got valacyclovir and it is the best thing I have ever used. The cold sore is gone in two days. I have cold sores for about 30 years and I am glad that whoever come up with this medicine THANK YOU SO EVERY MUCH."

"Woke to a hard lump which was a few small lumps about to turn into a big cold sore. Took the Valtrex right away and every 12 hours and it never even busted open or got bigger. Been 24 hours and it’s barely noticeable. Best thing for HSV1!"

"Thanks for the feedback. It has helped me feel better. I'm getting married in a day and a half and woke up this morning with an outbreak! I was so bummed out, so I made an appointment with the doctor immediately. She prescribed Valtrex, and it has been 7 hours since I took the 2 grams and its already starting to work! I hope I wake up and the blisters are all gone! "

"I use this medication as soon as I feel a tingle. I don't let it get bad or out of control. As soon as I take it, I notice the tingling stops. It's a very good medication for cold sores. I recommend it."

"Valtrex works. Around Christmas I got a cold sore and didn't have any on hand and wasn't able to get any - and that cold sore was the worst I've had in ages. It lasted a good 10 days and was huge. I've always taken Valtrex as soon as I feel one coming on, and it has always knocked it out almost immediately. It stops it in its tracks and the healing begins. The difference between using Valtrex and not using it, in my experience, is night and day. I highly recommend always having it on hand. 2 grams for the first dose, then 2 grams 12 hours later has always worked for me."

"THIS IS THE ONLY THING THAT HELPED SHORTEN THE LIFE OF MY COLD SORE so I felt I had to share because I tried it after reading a review similar to mine! Instead of the usual 2 weeks it takes to get rid of mine, it took 6 days!!!! Life changing. Good luck! You’re not alone! So many people have this! I took 2 of the pills twice a day for 2 days I think. The. I took one everyday after even though my doc told me to take one twice a day for 2 days and that was it. But I read other people’s reviews and they took it the way I did- and their doc told them to take that way. If it stops multiplying and changing then stop taking it. If it starts to flare up again, take another."

"To posters not getting relief - the manufacturer's recommended dosage for cold sore outbreak is TWO grams every 12 hours for 1 day. If you are not taking this dose that would be the reason it does not work for you. Some will heal with less but I suggest that your first time taking it, you take as is FDA suggested. For me at least (50 years of cold sores), if the sore is already in progress then TWO grams at least for the first dose is absolutely necessary. I then judge later at the 12 hour mark whether it is already responding and may only take 1 gram. If I catch it at first tingle then I get by with a single gram every 6 hours for 3 doses only. Personally I have learned to try and catch it early because 2 grams gives me a headache."

"I'm 19 years old and I've been getting cold sores ever since I was young...the last few years I would get them a couple times a month sometimes a new one every week. I've been taking valtrex for a few months now and I've gotten only 3 times (which is a major improvement) because I was sick and my immune system was down. But they went away after a day or so. I'm so so happy"

"I am 21 years old and I've been getting cold sores since I even remember. I am a new yorker so every winter there I am bound to wake up with multiple cold sores! My term saw me one day and prescribed me Valtrex. Life saver! It stops the itching and by the next day your cold sore is gone! I have tried everything else. "

"I have had cold sores since I have been a child. I would get them about every six weeks. I would treat them as soon as,I felt the the tingle.. A year ago I was getting tests done in preparation for a trip to Germany.. I had a fever blister. Dr prescribed Valtrex.. I took one pill for two days... I have not had another break out in over a year..miracle for me."

"Let me start by saying (1) I'm compulsive in terms of researching everything (2) I get the worst cold sores known to man and my lip blows up about 4x. With all that said, Valtrex is the real deal. A cold sore is a Virus (as I'm sure you all know by now) that injects its own foreign DNA into your cells which in turn mutates them which is why you get a cold sore - the way Valtrex works is by blocking the viruses ability to inject its own DNA into your cells. So, if you take Valtrex at the FIRST sign of "tingling", you may never develop a cold sore. I on the other hand developed a sore this past Tuesday (took Valtrex too late), have been taking Valtrex every 12 hours since, and it is now Friday, my lip is fully deflated and scabbed."

"Valtrex is amazing! I take 2,000mg 2x a day 12hrs apart at first outbreak & it either completely goes away or only lasts a few days instead of 2 weeks. If you get it early at burning, tingling stage, you won't get one at all. Prior to Valtrex I was taking Famvir, but they didn't work for me. So glad my doctor prescribed this medication... I only buy the brand as I find the efficacy better than generics"

"Does anyone else take Valtrex everyday for prevention? I am not so sure about Valtrex working for me. When I first started taking Valtrex, over two years ago, my dentist told me to take 4 pills at the first tingle sign and then again 4 pills a certain amount of time later. I always followed the directions. It never really seemed to make a difference, a cluster of blisters always showed up. It might have shortened the healing time. After three months in a row of sores, I called my family doctor in tears. So for over a year and half now, I have been taking a Valtrex everyday as prevention. I think I had an outbreak in the early part of the year and one in November and now one in December. It just STINKS!!"

"Honestly this is the only medication that has ever worked for my cold sores. Seems like as soon as I take the first dose the sore won't get any larger than it is at that moment and it begins to heal. Still goes through the stages of a scab but is much easier to live with and not nearly as visible, unsightly, or long lasting as they were in the past."

"I've had coldsores for as long as I can remember. I used to get it every few months until about grade 12 where I would get it 1-2 times every month (and they like to spread). They were so bad that my lips are permanently discoloured. It was a teacher that recommended me to ask my doctor about valtrex and every since then I finally have them under control with only one getting the best of me every few months. If you're someone that struggle taking pills it's going to be hard on you, but it's completely worth it."

"Ok, I have suffered with cold sores immensely. My Dr prescribed me this medication and it has really helped me. The kicker happened today. I went to refill my prescription and they have raised the price by $100.00!! I almost fell over. This is horrible, I can't afford this every month. What a load of crap. Apparently, they won some lawsuit. Well back to lips full of sores for me I guess."

"2 pills 2x a day. This makes my cold sore heal so quickly. A few months ago I felt one coming and bit open a little pustule (the baby liquid filled blister) NOTE: do NOT bite or puncture these open if possible. Once the liquid is out it spreads the virus and that makes it become to ugly huge cold core we all know. So if you don't pop those, that helps the healing process sPeed up. I took 2 Valtrex as soon as I accidentally bit one open then 2 pills at night and my cold sore never got big or obvious. As I get older and stress takes it's toll, I have been prone to cold sores yearly, and Valtrex has made my life better. I also have Zovirax topical ointment I put on if the cold sore is big. So I double on my fighting power."

"My sister and I have always gotten fever blisters. I’m convinced that we got them from our mom when we were babies because she has the same issue. We both get them on our chins, cheeks, foreheads, nose, lips...you name it! They are very embarrassing and even more painful. They were all over my face, like multiple blisters when I went for my Pap smear years ago. When he saw them, my OBGYN gave me a prescription for once a day Valtrex. I took it daily for a year and didn’t get an outbreak for 3 years. Then, I had to start taking it daily again. After stopping for another year, I started getting them on my cheeks and mouth again. Taking 4 twice a day for one day at the first sight of one hasn’t been helping and another just comes back somewhere else, so I have obtained a 90 day prescription and plan on taking it daily for longer than a year for suppression. I’m so sick of dealing with HSV-1 it’s unreal! Valtrex works if you’re consistent with it and are aware of your body."

"I hate cold sores. I have gotten them sporadically for years and have tried it all. I had taken acyclovir pills and found that they did not help once the sore had broken the skin. Yesterday I woke up with a sore forming and FREAKED. I have a black tie event this weekend and needed it GONE. I ran to my Dr. and took my first dose of Valtrex around 11am. I did notice that it didn't really get bigger, but it wasn't disappearing. I took my second dose and went to sleep, this morning I woke up and while the sore is still there, it's already scabbed and MUCH better. I think it should be in a great place tomorrow for my event. While it didn't clear it up completely - it helped SO much in 24 hours. Now I can at least use some concealer!"

"Recently had a breakout, I haven’t had one in almost two years. The last time I had one I went to urgent care and the doctor prescribed me Valtrex. I was a couple of days into the outbreak but saw a MAJOR difference it made in symptoms such as pain and swelling. This past Monday a bump appeared on my bottom lip and I took Valtrex. Anyone who has experienced these outbreaks know how painful and embarrassing they are. So of course my mind just went to a sad place. LUCKILY Valtrex kicked in right away! I didn’t have the awful swelling or pain! Only one blister came about and weeped. Got a scab on day three and it has basically gone now…the scab fell off last night. So what would have lasted 10 days cleared up in 7 and that’s probably only because I waited to take it rather than right away. Already got my prescription refilled. I’m so happy I was introduced to something that not only relieves symptoms but clears up these nasty breakouts quickly!"

"Hi, After suffering these horrid, sometimes extremely painful ugly blisters for years I am glad I found a doctor who prescribed this drug Valtrex. Sometimes my blister would last up to 10 days and then one on each side of bottom cheek! Now at the first niggle I start taking them. I only need to take Valtrex x 2 daily for 5 days and I have relief - until the next big stressful event. But I only need to take them again for 5 days. Happy."

"Works everytime. I always keep 2grams valtrex so I can take at earliest sign of oncoming cold sores. If you take in time it sometimes stops the cold sores completely. It's all about the timing... For me I get a tingle in jawline, I take 2 grams right away. Then 2 grams when I get home or 12 hours later. That's it.. best thing other than a cure"
