Things To Know About Cold Sore

Anti-Herpetic Drugs – How They Work
  • Cold Sores can remain for 7 to 14 days when the virus is active
  • The tingling, itchiness, and burning starts about 48 hours before the blister

There is no relation to having a cold sore and a viral flu-type infection. Some people will have outbreaks at this time because their immune system is already lowered. Drink plenty of water and rest if you have both infections at the same time.

Keep all appointments with your doctor and the laboratory. Your doctor may order certain lab tests to check your response to acyclovir.

Do not let anyone else take or use your medication. Ask your pharmacist any questions you have about refilling your prescription.

It is important for you to keep a written list of all of the prescription and nonprescription medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.

How Valtrex Works On Cold Sores

It slows the growth of the Herpes Virus. Valtrex is an antiviral medication that can be taken before the blisters appear. If caught early enough, Valtrex will halt cold sores completely.

The main active ingredient is valacyclovir hydrochloride. This ingredient is also used with HIV patients to help prevent outbreaks of Herpes infections. For an already weakened immune system, Valtrex can slow down reoccurring viral outbreaks.

Valtrex does not cure herpes and may not work if you didnt catch it early enough. The objective is to stop the virus and return it to a dormant state. Take the medication as soon as you feel any burning, itching, and tingling sensations.

Shocked? You shouldnt be, since the virus is very common. According to the World Health Organization, 3.7 billion people under age 50 have herpes simplex virus type 1 thats 67 percent of the global population in that age bracket. Another 417 million people between ages 15 and 49 worldwide have herpes simplex virus type 2 .

Many people consider HSV-1 more benign, but it turns out theres not much difference between the two types of virus. While its true that HSV-2 is a sexually transmitted disease and can cause genital sores or blisters, type 1 can do the same thing.

One big misconception is that cold sores are caused by HSV-1 and genital herpes are always type 2, but thats not always the case, says Sarah Vensel, a physician assistant in San Francisco. Cold sores are so common theyve been normalized at this point. But genital herpes is sometimes the exact same virus just in a different location.

Don’t Miss: What Are The Effects Of Herpes

Is There A Cure Or Treatment For Herpes

There is no cure for herpes. Antiviral medications can, however, prevent or shorten outbreaks during the period of time the person takes the medication. In addition, daily suppressive therapy for herpes can reduce the likelihood of transmission to partners.

Several clinical trials have tested vaccines against genital herpes infection, but there is currently no commercially available vaccine that is protective against genital herpes infection. One vaccine trial showed efficacy among women whose partners were HSV-2 infected, but only among women who were not infected with HSV-1. No efficacy was observed among men whose partners were HSV-2 infected. A subsequent trial testing the same vaccine showed some protection from genital HSV-1 infection, but no protection from HSV-2 infection.

Side Effects And Follow

Valtrex (Valacyclovir) – Uses, Dosing, Side Effects

Side effects with these herpes drugs are considered mild, and health experts believe these drugs are safe in the long term. Acyclovir is the oldest of the three, and its safety has been documented in people taking suppressive therapy for several years.

People taking suppressive therapy should see their doctor at least once a year to decide if they should continue. You may find taking the pills every day to be inconvenient, the drugs may not work for you, or you may naturally have fewer outbreaks as time goes on. Your doctor can help you make treatment choices to suit your needs.

Genital Herpes During Pregnancy


Prevention of neonatal herpes depends both on preventing acquisition of genital herpes during late pregnancy and avoiding exposure of the neonate to herpetic lesions and viral shedding during delivery. Mothers of newborns who acquire neonatal herpes often lack histories of clinically evident genital herpes . The risk for transmission to the neonate from an infected mother is high among women who acquire genital herpes near the time of delivery and low among women with prenatal histories of recurrent herpes or who acquire genital herpes during the first half of pregnancy . Women who acquire HSV in the second half of pregnancy should be managed in consultation with maternal-fetal medicine and infectious disease specialists.

All pregnant women should be asked whether they have a history of genital herpes or genital symptoms concerning for HSV infection. At the onset of labor, all women should be questioned thoroughly about symptoms of genital herpes, including prodromal symptoms , and all women should be examined thoroughly for herpetic lesions. Women without symptoms or signs of genital herpes or its prodrome can deliver vaginally. Although cesarean delivery does not eliminate the risk for HSV transmission to the neonate , women with recurrent genital herpetic lesions at the onset of labor should have a cesarean delivery to reduce the risk for neonatal HSV infection.

    Warnings For Other Groups
