"I had suffered through many cold sores, and spent tons of money on abreva. When my doctor prescribed me valtrex I was finally satisfied because within the first tingling feeling , and me taking valtrex most times the cold sore just disappears. I can take valtrex at the first symptom , and it's no longer an issue. Most times not even my boyfriend will see the bump , and I have to point it out. I love valtrex, and am extremely happy with my results."

"Like so many others here, I've had cold sore outbreaks here and there since I was a little kid. It was Always a source of anxiety for me, either when I had one, or just worrying about when the next one was coming. I'm in my 30s now. About 2 years ago, I had my dentist call in a prescription when I had felt one coming on for a few hours ( the bump was forming ) not knowing what would happen. He called it in. I took my first dose within an hour. It never really formed, just stayed a bump for a half day or so and then flattened out and healed quickly. Since then I've always made sure to keep it on hand at home at my office. I've taken it several times since at the first signal and its been all clear. Cannot recommend enough!!"

"I've had outbreaks with cold sores for about 10 years now on average 1-2x year, the last few years primarily due to stress and weather changes. The main key to the success of Valtrex - as with any OTC, prescription or home remedy for cold sores/fever blisters - is timing. Take it at the first tingle. I keep Valtrex refilled and keep it handy, regardless of whether I need it. I felt a tingle and a bump the other day, took it and it has helped tremendously. It's been 48 hours now and it has progressed past a slight red bump with no pain or bleeding. I haven't had a major outbreak in over 2 years. If you are able, keep it handy. As someone who has had some dreadful experiences with cold sores, I can say it works-but timing is important."

"Valtrex is the only way to go. I have suffered with fever blisters as long as I can remember and they are just miserable. I get them when I run fever, sunburn on my lips, or are really stressed. Woke up with one this morning...I took Valtrex, and it will be gone by nightfall. My son also has problems with fever blisters, but they break out underneath his eye. Since he has been taking Valtrex, he has not had any problems. I also had the Shingles vaccine, which has cut down on my fever blister outbreaks unbelievably. I still get them, but usually as a result of illness. This is the best medication to come out to fight the herpes virus, ever!"

"Suffered from cold sores since a young teen. Not only do I break out from large ones that cover half my lips but I will get them on my cheeks. Without treatment they will last around 9 days. I take valtrex at the first signs. I will take 4 pills and then another 4 12 hours later. I just had a break out and the bump was already big and itchy took my 4 pills before bed and another 4 when I woke up. Bumps were gone with no cabbing by day 2!"

"I love this medicine!!! I've had cold sores since i was a kid and none of the over the counter stuff ever worked for me. I take it as soon as i feel that tingle and it's usually gone in 2 days. I recently had a bad illness and broke out with 5 blisters after a night of 103 fever. I took two pills in the morning and at night and all but one blister is gone! I would have been so miserable if i didn't have this miracle to take!"

"This drug is a miracle! I woke up with a full blown cold sore and went to the Doctor who gave me Valtrex. I was very skeptical because the cold sore was pretty big already, but 12 hours after my first dose, it looks much better and the pain is gone. Will never again waste my time or money on OTC cold sore treatments. This stuff really works!"

"I have gotten cold sores/fever blisters since I was a young boy. I too have tried it all. I find that taking a small amount of Lysine and eating a Lysine rich diet, low in arginine help to prevent them, but they inevitably come around. I just had a cold sore and it was a tricky one. Sometimes they don't start tingling until it has already swollen. Once I realized it was one, I had waited a full day too late, but I was still very impressed. Thirty minutes after taking one, the tingling stopped. The next morning it was half the size. I had two that day and by the third day it was gone. I have every hope that if I take it within an hour next time, it will stop it cold. Awesome."

"For those who are prescribed Valtrex who then report they have not gotten relief--make sure your next prescription is not filled with the generic version. That happened to me, I had been taking Valtrex for about 10 years with great success. Then it stopped working to my dismay. I realized the prescription bottle contained the generic version. I had to go back to my dr and explain the generic version's ineffectiveness on me and to specify NO GENERIC. I'm back on Valtrex and it works wonderfully."

"Valtrex works wonders. As a 20 year old college student, exam time usually involves catching a cold and high stress, and the perfect formula for cold sores. Last night I started feeling one start to pop up around 8pm. I got home around 9:30pm and popped two 1 gram pills of Valtrex. At 9:30am today I got up and took two more. The cold sore did bubble up some but never got swollen, nasty and red. Its 5:30 pm now and its almost completely gone! Without the Valtrex, I would be sporting a disgusting throbbing blister for a couple days followed by a week of waiting for a scab to heal. I'll take the 24 hour cold sore over that any day. Please, if you suffer from these painful, embarrassing cold sores, try to get a prescription."

"My dentist prescribed me Valtrex for cold sores I get on my gums (and occasionally on the lips, though that is much less frequent). At the first sign of outbreak, usually a small blister or a couple of them, I take 2000mg every 12 hours for one day. Valtrex keeps it from spreading; I never get any more blisters than on first onset. They also never crack or crust over. Within about 3 days they're completely gone. I swear by this medication for intra-oral cold sores. The only side effect I seem to get is a bad headache. Definitely worth it."

"I can't say enough good things about it. The difference between my fever blisters with and without the pill is truly like night and day. I started taking 1 pill as soon as I see a bump or feel tingling and the symptoms are reduced by >60%. Definitely worth going to a doctor to get a prescription!"

"This medicine is absolute magic! I only get a cold sore once a year like clock work. Always in Novemeber when the weather gets cold, and life gets hectic. I get it within the same week every year, I take this medicine as soon as I see it coming on and I get that tingle! Seriously within 1-2 days the cold sore is completely gone, looks a little red that's it can't even tell. Absolutely amazing would recommend to anyone!"

"I'm 24 years old as a young female a cold sore was terror. I have always gotten them on and off throughout out the year and more so in the winter. As I got older stress and worry would trigger a cold sore and when I thought I had it healed another would come up right next to it. I tried everything OTC and anything to dry it out. Needless to say I was torturing myself until I mentioned to my Dr that I get them under stress and once one healed another came along. He suggested Valtrex 500 mg and to take one tablet everyday! I haven't had a cold sore since. And I've had a ton of stress since. My Dr is amazing and this is a miracle medication. "

"First time I used valtrex, I thaught I was done or almost done with cold sores, it healed up so fast I was really glad something was finally helping me for real. Abreva and all the other stuff don't really work, I'd even say abreva makes it worst. But in the last 5 months I had 2 cold sores unfortunatley, both time I took valtrex as soon as I felt a little tickling. No matter what, both time I woke up with a full blister and bigger. So people saying it stops it right in its track are wrong. But it does help for the healing time. In 5 days its gone. Still better then the 7-9 days i used to go through before. Can't wait till they find a real ''cure'' or at least something that kills the virus for real as soon as you take it."

"I got up Sunday morning with a cold sore. Didn't get chance to take Valtrex until Monday afternoon around 2 pm. By Tuesday morning it was already clearing up. And by Thursday it was gone. Usually without taking any medication my cold sore would last about a week and a half to two weeks."

"I am so happy I found this! Or rather, found a doctor that prescribed it. It’s a Miracle drug! I get probably 4-5 cold sores a year particularly when I’m extra stressed which is always the worst time for a cold sore. I never feel them coming the night before. I always wake up with several blisters that formed overnight. Anyway, I immediately take 2 grams of Valtrex (I always have it on hand! I get my prescription refilled immediately after I use it in prep for the next one). By mid afternoon, it’s stopped itching. I take 2 more grams before bed. The next morning it’s grown a little but not bad. 2 more grams that second morning. By the afternoon of the second day, the blisters are mostly gone and only slight scabs remain. I’m lucky that mine are in the corner of my mouth. You can’t even see it by the second afternoon. I then reduce to 1 gram morning and night for a week just to be sure it’s totally gone (I’ve had them come back!)"

"By far the best (and only) medication to ever help my cold sores. I would get large painful blisters at the center of my upper lip that would stretch out to below my nose. They would take a week to break open, and at least a week but usually two for the scab to heal over and after that I would deal with a large red patch of skin there for another several weeks before fading back to normal. With my last outbreak I had Valtrex on hand and took the first dose within a few hours and two days later it's almost completely healed and no one has even been able to tell I had/have a sore. I will always have this medication on hand! I've been dealing with these for 10 years, not to oversell it but this medication has changed my life!"

"I've been getting cold sores since I was 10yrs old and they get really bad. As I've gotten older they only occur once a year if I'm really stressed, not getting enough rest and not eating right. Talk about embarrasing it spreads across my entire upper lip then the crust and scab process is awful and unsightly mines usually last about 3 weeks..Sucks in a major way!! Went to the MD in the middle of this out break because is was spreading and I was totally depressed she prescribed Valtrex every 8 hours for seven days I've taken two so far and the blisters stopped forming wish I would have taken it at the first sign. I'm impressed with this medication I will be monitoring to see if it helps with healing and pain."

"Like so many of you, I have had a lifetime of cold sores. I want to share an experience with a doctor. I passed out during final exams because I had 18 fever blisters at once and I had gotten poisoned by it. The doctor told me that people like me carry herpes simplex type 2 virus in nerve ending of our spine and that when we are run down the immune system can't keep it under control and it comes out again. So that was a revelation. Anyway, valtrex has been a life saver. I tried everything as well - but nothing has ever come close to helping me until Valtrex. Thank you!!"

"I've been getting cold sores for a while now and before Valtrex, none of the creams would help and I wouldn't notice a difference. Now when I feel a little bump I take Valtrex right away, 4 pills asap then another 4 a few hours later. If I catch it early enough it won't go past the little bump and will be cleared up by the next day. If I catch it a little too late (sometimes they like to show up while I'm sleeping). I still take Valtrex and I will get the outbreak but no swelling, blister. Still clears in 3 days. I also use polysporin patches. This stuff is the closest thing to a cure right now. My doctor says take 1 pill a day around the times of the year I usually get them and sometimes I can go a year or year and a half without one."

"Had one of those tricky cold sores where there is no tingling or burning, it just up and shows up out of no where. Showed up as a single blister around 10pm and I knew there was nothing I could do except ice it until the morning. Continued to ice all night in the hopes that it would not get worse and went to the doctor first thing in the morning. Took 2 pills in the morning and 2 pills at night and it is essentially gone, two days later. Never broke open, never crusted. Just kinda disappeared, all because of this little miracle pill. Definitely worth going to the doctor for - hopefully one day it will be available OTC!"

"wow is all I have to say. Anyone who has cold sore know the minute it happens your worried how big how long. I was driving home from work Monday at 6 pm felt the tingle freaked out took the valtrex and again in the morning. I was worried cause it did seem to grow. But by the end of Tuesday it was not as bad as it would have been. Next morning I was shocked. Normally waiting for that blisters and gross that you know comes. But it was flat. No blister it seemed to stop all production. Yes what's there is healing but wow it's basically at the end of a cold sore. Not where it should be like the beginning. I will keep this on hand always. Amazing. I am so happy."

"I would never take the time to do this if this pill didn't truly change my life. I have gotten cold sores for years now, just about every month. I finally asked my dentist if he could prescribe something for me because my wedding is coming up and I DID NOT want to have one on my big day. I have used the medicine twice now.. The first time a blister never even formed I just had the hard bump on my lip and it was gone by the second day. I felt my lip getting hard again Sunday so I immediately took 2 pills and then 2 more 12 hours later. Monday morning I woke up and a small blister had formed(didn't hurt or look bad but I was still worried.) It is now Tuesday morning and my lip is completely healed! This pill works miracles!"
