Valacyclovir is used to treat infections caused by certain types of viruses. In children, it is used to treat cold sores around the mouth (caused by herpes simplex) and chickenpox (caused by varicella zoster). In adults, it is used to treat shingles (caused by herpes zoster) and cold sores around the mouth. The viruses that cause these infections continue to live in the body even between outbreaks. Valacyclovir is also used to treat outbreaks of genital herpes. Valacyclovir decreases the severity and length of these outbreaks. In people with frequent outbreaks, this medication is used to reduce the number of future episodes. It helps the sores heal faster, keeps new sores from forming, and decreases pain/itching. This medication may also help reduce how long pain remains after the sores heal. Read the Patient Information Leaflet if available from your pharmacist before you start taking valacyclovir and each time you get a refill. Valacyclovir (generic for Valtrex) is a medication approved by the FDA to treat different types of herpes infections including HSV-1 and HSV-2. It is also used to treat shingles (herpes zoster), which is caused by the Varicella Zoster Virus (VZV). There are four different ways that herpes medications can be used to treat genital herpes (HSV-1 and HSV-2): 1. To Treat Or Abort An Outbreak When There Are Early Symptoms (Prodrome): For both genital and oral herpes, people can take medication when their specific prodrome tells them an outbreak is about to occur. The medication will stop an outbreak cold (often) and when it does not, it can shorten the outbreak and make it milder than it might have been otherwise. To Prevent Outbreaks When There Are No Symptoms But Outbreaks Are More Likely: Patients also learn the life circumstances or behaviors that lead to more outbreaks. For some, a lack of sleep, increased alcohol, another illness, stress, too much sunlight, irritation, or anything that can affect one’s immunity can spur an outbreak. That means that some patients can know not just when they feel an outbreak coming on but can know when they are more likely to have an outbreak due to their circumstances. They might be under stress, having more sex therefore causing more physical irritation, drinking a bit more than they should, or missing sleep over an extended period.

Over the day the swelling went down, the bumps flattened. 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. While these reviews might be helpful, they are not a substitute for the expertise, skill, knowledge and judgement of healthcare practitioners in patient care."I’ve gotten horrific cold sores ever since I was a kid. If you're someone that struggle taking pills it's going to be hard on you, but it's completely worth it.""Thank you for this medicine! I get mega cold sores they can take over my entire bottom lip. There have been many times that I stayed home from work and school because I felt so disgusting, but thanks to this stuff I don’t have to worry about that so much anymore. Not only are they embarrassing but also incredibly painful. As soon as I feel that awful itch that indicates the cold sore coming through I take one of these pills and a second 12 hours later. I had a dermatologist that began prescribing me 1g tablets and instructed me to take 3 whenever I feel like a cold sore might be coming on. I used to get outbreaks at least once a month and now I only get them 1-2 times a year! ""I started to get cold sores about 1x/year starting 10 years ago. I already had Valacyclovir on hand and ready though it had never worked because I hadn’t taken the right dosage. They will either completely prevent the cold sore from coming through or at the very least minimize the appearance and speed up recovery time. Then found this thread, saw everyone took 2 g, so took 2 g that night (2 nights ago now). Today it’s gone though I swear I can feel a slight tingle, may take a lighter dose to prevent it returning. Whatever little swelling was there just disappeared. They were so bad that my lips are permanently discoloured. I woke up and took the second dosage at am and now it’s gone! I could feel it erupting - took the medication and the very next day I was 95% healed. 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). I didn’t have any medicine with me at work and wasn’t able to get my first dosage of 2g until 6pm. One maybe every 4 years or so but this year I had 2 wishing 4 months time so I was ready with medication on hand just in case and it literally was amazing. Decided to jump in and let me tell you, the benefits outweighed my fears. Sometimes my blister would last up to 10 days and then one on each side of bottom cheek! I only need to take Valtrex x 2 daily for 5 days and I have relief - until the next big stressful event. Happy.""I've had coldsores for as long as I can remember. Valacyclovir works best if it is used within 48 hours after the first symptoms of shingles or genital herpes (e.g., pain, burning, or blisters) begin to appear.
