The classic example would be during a honeymoon but taking medication to suppress outbreaks on a daily basis can be prudent when going on vacation, starting a new job, in a new relationship, or at any time a patient feels it is how they want to approach their condition. How medication is used is completely in your hands. Learn everything you can and do not worry about using the medication in the way that suits you best.
That may change as your circumstances change, or as the condition changes, or even as your mind changes. To prevent transmission to an uninfected partner One of the most important advances in herpes treatment came with the knowledge that transmission from an infected person to their uninfected partner could be reduced by the use of valacyclovir. Valacyclovir not only reduces the number of outbreaks a person experiences when using the medication every day but it reduces the number of days that someone sheds the virus asymptomatically.
That results in fewer uninfected partners catching herpes. If a condom is worn and the medication used, the chances are reduced at least in half compared to using a condom alone. Fewer outbreaks and fewer episodes of shedding means fewer people become infected. Oral herpes Abort an outbreak at the earliest sign or symptom prodrome At that earliest sign, two tablets of valacyclovir mg for a total of mg is taken by mouth as the first dose. Then, 12 hours later, 2 tablets of mg of valacyclovir, for a total of mg, is taken as the second and final dose.
The second dose can be taken sooner than 12 hours but never before 6 hours have passed. Adequate hydration makes sure the medicine is cleared through the kidneys as it should be. The medication is only approved for two doses and there is no evidence in studies to advise the use of medication once lesions have appeared. Treatment of initial genital outbreak In patients with a first outbreak, the symptoms can be very severe.
Multiple painful, genital ulcers can cover large areas of skin on both sides of the groin. They can experience burning during urination, fever, headaches, muscle and joint pain, and swollen, painful lymph nodes in the groin. For such patients, treatment is vital and can shorten the outbreak and ease the symptoms significantly. For the treatment of an initial episode of herpes genitalis, the FDA recommends taking valacyclovir 1 gram mg twice a day for 10 days starting at the first sign or symptom of lesions, preferably within 48 hours of onset.
Treatment of herpes labialis i. The second dose should not be taken within 6 hours of the first. Those are the only doses recommended but patients sometimes take another dose or two of just 1 gram if they continue to have symptoms, or if a mild outbreak follows.
The CDC recommendation is identical but adds in the choice of using valacyclovir 1 g mg one time a day for 5 days. Valacyclovir 1 g taken every 12 hours for 5 to 14 days is recommended by the HIV guidelines.
In HIV-infected patients, mg by mouth twice daily. The safety and efficacy of therapy beyond 6 months have not been established. An important point Being diagnosed with genital herpes means you have acquired a sexually transmitted infection.
If you have been diagnosed with genital herpes, you should have been checked for other sexually transmitted infections when you were diagnosed, including but not limited to HIV and syphilis.
If you have not been, you should be and this is highly recommended. Herpes can be transmitted to a partner despite best efforts like using a condom and using antiviral suppression therapy.
Also, as asymptomatic shedding is more common in the seven days following an outbreak it is prudent to avoid sex during that period, as well. The reason is that herpes creates ulcers that can make it easier for HIV to enter the body but general inflammation of the genitals is also responsible for the increased vulnerability to the infection.
In women and men with positive blood tests for herpes, specialized testing shows signs of inflammation on the cervixes of women and under the foreskin of men.
The specialized test is the finding of CD4 T cells. Of note, some CD4 T cells have been shown in the lab to be more susceptible to HIV infection than skin samples tested under the same conditions. Moreover, CD4 T cells hang around in inflamed tissue long after outbreaks heal. This is another reason why STD testing is always the rule when beginning a new sexual relationship and why, whether having an outbreak or not, a condom is essential.
Herpes itself may behave identically in the HIV positive individual but they are more likely to develop acyclovir resistance and to have outbreaks that last longer and appear different from typical cases. HIV positivity is a complex condition that requires careful evaluation by experts in the field. HSV vaccines After years of frustration, there are reasons to be optimistic that a vaccine to prevent, or even to treat, herpes may be achievable.
The development of a vaccine has been spurred by the realization that controlling herpes would be a major step in controlling the spread of herpes around the world, especially in places where medication is unavailable. Herpevac vaccine did not prevent the acquisition of genital herpes Type 2 but it did show moderate success against catching herpes Type 1 and in making the disease milder if someone caught it.
The study included participants but they were all women so the data may not be consistent in men. Nevertheless, the fact that a vaccine worked for HSV-1 is encouraging, especially since so many new cases of genital herpes are due to HSV A number of vaccines are being tested to see if they could reduce the number of outbreaks and, most importantly, the amount of asymptomatic shedding. The advances are being made that give hope to anyone who has the infection or is the partner of someone with the HSV virus.
Read full prescribing information Here How can Valtrex be used Treatment of herpes labialis i. The CDC recommendation is identical but adds in the choice of using Valacyclovir 1 gram mg one time a day for 5 days.
Valacyclovir 1 gram taken every 12 hours for 5 to 14 days is recommended by the HIV guidelines. Safer sex practices should be used with suppressive therapy. Safety has not been established in neonates, infants, and children less than 2 years.
Dose adjustments should be made for those with kidney impairment or issues. Decreased doses are needed as kidney impairment slows the clearing from the body of valacyclovir. The degree of impairment determines the decrease in the dosage.
The elderly may have decreased kidney function and adjustments should be considered in such cases. No adjustment is needed, generally, in patients with liver impairment. However, if you have a liver condition or impairment, inform your doctor. Overdose: Valtrex is not usually harmful unless you take too much for several days. For severe symptoms, go direction to an emergency room.
Otherwise, talk to your doctor or pharmacist if you take too much Valtrex. Take the medicine pack with you. Sensitivity or Allergies: Patients with sensitivity or an allergy to any of the following medications should not use Valacyclovir: Acyclovir, Famciclovir, ganciclovir, penciclovir, valacyclovir, or valganciclovir. Kidney Issues: Dose adjustments should be made for those with kidney impairment or issues. Patients receiving potentially nephrotoxic Toxic to the Kidney drugs together with valacyclovir may have an increased risk of renal dysfunction impairment.
This can lead to inappropriately high levels of valacyclovir, which means the elderly may need lower doses of valacyclovir.
The elderly are also more likely to experience neurological side effects, including: agitation, hallucinations, confusion, delirium, and other abnormalities of brain function termed encephalopathy. Dehydration: When patients are dehydrated acyclovir can reform as a solid in the kidney leading to kidney damage.
Patients should all remain well hydrated when taking valacyclovir. Newborns, Infants, and children: Safety has not been established in neonates, infants, and children less than 2 years. Pregnancy: While a registry that collected data on the pregnancies of women exposed to acyclovir in the first trimester showed no greater occurrence of birth defects than occurs in the general population, the study size was too small to guarantee safety during pregnancy.
Although the American Academy of Pediatrics AAP has not specifically evaluated valacyclovir, systemic maternal acyclovir is considered to be usually compatible with breastfeeding…Consider the benefits of breastfeeding, the risk of potential infant drug exposure, and the risk of an untreated or inadequately treated condition. If any of these conditions apply to you, please inform your doctor and pharmacist.
What follows is a summary and does not include every side effect possible. Please, read the package insert and report any side effects you experience whether on the list below or not.
They usually get better when Valtrex is stopped or the dose reduced. Other Uncommon Side Effects: shortness of breath dyspnea , stomach discomfort, rash, sometimes itchy, hive-like rash urticaria , low back pain kidney pain , blood in the urine hematuria Uncommon Side Effects That May Show Up In Blood Tests: reduction in the number of blood platelets which are cells that help blood to clot thrombocytopenia , reduction in the number of white blood cells leukopenia , increase in substances produced by the liver Rare may affect up to 1 in 1, people : unsteadiness when walking and lack of coordination ataxia , slow, slurred speech dysarthria , fits convulsions , altered brain function encephalopathy , unconsciousness coma , confused or disturbed thoughts delirium These nervous system side effects usually occur in people with kidney problems, the elderly or in organ transplant patients taking high doses of 8 grams or more of Valtrex a day.
Other Rare Side Effects: kidney problems where you pass little or no urine. Lastly, watch out for a severe allergy. It may be rare but it can be life-threatening so being aware of the symptoms is vital. Severe allergic reactions anaphylaxis : These are rare in people taking Valtrex.
Anaphylaxis is marked by the rapid development of flushing, itchy skin rash, swelling of the lips, face, neck, and throat—causing difficulty in breathing angioedema , fall in blood pressure leading to collapse. If any of these occur, get emergency treatment immediately. Therefore, when VALTREX is coadministered with these drugs in patients with normal renal function, no dosage adjustment is recommended.
Together, the risk to the kidney is increased. Bictegravir; Emtricitabine; Tenofovir Alafenamide: Tenofovir is primarily excreted via the kidneys, as is valacyclovir, so Tenofovir should not be used if a patient is on valacyclovir or has been on it recently. Cimetidine: Cimetidine may slow how quickly valacyclovir is cleared out of the body through the kidney but no dosage adjustments are recommended for patients with normal renal function.
Cobicistat; Elvitegravir; Emtricitabine; Tenofovir Alafenamide: Tenofovir is primarily excreted via the kidneys, as is valacyclovir, so Tenofovir should not be used if a patient is on valacyclovir or has been on it recently.

Entecavir: Entecavir can affect kidney function and should be used cautiously with valacyclovir. Fosphenytoin: Phenytoin and fosphenytoin are anti-seizure medications. The addition of valacyclovir to phenytoin may lead to a clinically significant decrease in phenytoin serum concentrations and loss of seizure control.
Adjustments in phenytoin or fosphenytoin dosing should be considered if Valacyclovir is added or stopped when a patient is on either phenytoin and fosphenytoin.
If they take any other drug that can affect the kidney, including valacyclovir, the dose of IG may need to be lowered and the infusion rate slowed. Lamivudine; Tenofovir Disoproxil Fumarate: Tenofovir is primarily excreted via the kidneys, as is valacyclovir, so Tenofovir should not be used if a patient is on valacyclovir or has been on it recently. Measles Virus; Mumps Virus; Rubella Virus; Varicella Virus Vaccine, Live: Major If possible, discontinue valacyclovir at least 24 hours before administration of the varicella-zoster virus vaccine, live.
Also, do not administer valacyclovir for at least 14 days after vaccination. The medication might have the unintended effect of diminishing the protective benefit of the vaccine. When this combination must be used careful blood monitoring is recommended. Phenytoin: Phenytoin is an anti-seizure medication.
The addition of valacyclovir to phenytoin may lead to a clinically significant decrease in phenytoin levels and loss of seizure control. Adjustments in phenytoin dosing should be considered if valacyclovir therapy is added or discontinued.
In the absence of a decrease in renal function, no dose adjustment is needed. Talimogene laherparepvec is a live, attenuated lessened capacity to cause disease herpes simplex virus that is sensitive to acyclovir; coadministration with antiviral agents may cause a decrease in efficacy. Since telbivudine is also cleared by the kidney, monitoring kidney function before and during telbivudine treatment is recommended.

Endurance Wipes. Read on to learn how Valtrex works and how to use it to treat your cold sores. Cold sores typically start to heal on their own within about four to six days.
Although, the first cold sore you get will likely last longer. To treat a cold sore, you take Valtrex on the day you notice a cold sore forming. Valtrex works by preventing the herpes virus from growing and spreading. Your doctor may also prescribe Valtrex to help prevent future cold sores, which is an off-label use. In that case, you and your doctor would work together to create the best treatment plan for you. Valtrex is an oral caplet. It comes in milligram and 1-gram strengths. The generic product is an oral tablet which comes in the same strengths.
The recommended dosage is 2 grams twice daily, taken 12 hours apart, for one day. Valtrex should be started at the earliest signs of a cold sore. If you miss a dose of this medicine, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule.

The areas affected by genital herpes, chickenpox, or shingles should be kept as clean and dry as possible. Also, wear loose-fitting clothing to avoid irritating the sores blisters. It is important to remember that this medicine will not keep you from spreading herpes to others.
Herpes infection of the genitals can be caught from or spread to your partner during any sexual activity. Even though you may get herpes if your partner has no symptoms, the infection is more likely to be spread if sores are present.
This is true until the sores are completely healed and the scabs have fallen off. Therefore, it is best to avoid any sexual activity if either you or your sexual partner has any symptoms of herpes. However, spermicidal sperm-killing jelly or a diaphragm will probably not help. Along with its needed effects, a medicine may cause some unwanted effects.
Although not all of these side effects may occur, if they do occur they may need medical attention. Some side effects may occur that usually do not need medical attention. These side effects may go away during treatment as your body adjusts to the medicine.
