Patients with herpes zoster ophthalmicus are treated with oral acyclovir (800 mg, five times daily) for seven to 10 days. It also demonstrated that there is no benefit to adding oral acyclovir in stromal keratitis if the patient is already taking topical steroids and antivirals.
Herpes zoster, also known as shingles, results from reactivation of endogenous latent VZV infection within the sensory ganglia. High-dose oral acyclovir in acute herpes zoster ophthalmicus: the end of the corticosteroid era. Studies in patients with symptomatic recurrent genital herpes have shown that valacyclovir has comparable efficacy to acyclovir 8, 9.
I went in today to see my doctor and she suggested that rather than be on Acyclovir (as I have been: 400mg 5x per day with an awareness that this is a high dosage and we will be decreasing it) to suppress my herpes simplex 2 and associated unexplained sexual sensitivity loss, that I should go on Valtrex as it is a better drug.
Clinical utility of oral valacyclovir compared with oral acyclovir for the prevention of herpes simplex virus mucositis following autologous bone marrow transplantation or stem cell rescue therapy.
The efficacy of valacyclovir and acyclovir on genital herpes simplex virus (HSV) shedding was assessed in a double-blind, 3-period crossover trial. Valaciclovir compared with acyclovir for improved therapy for herpes zoster in immunocompetent adults.
Acyclovir (Zovirax) : Acyclovir has been studied and used for many years as a treatment for shingles. Oral acyclovir therapy for herpes zoster has been studied in double-blind, placebo-controlled trials of two dosages, 400 mg and 800 mg five times per day for 10 days. The quantitative relationship between the in vitro susceptibility of herpes viruses to antivirals and the clinical response to therapy has not been established in humans, and virus sensitivity testing has not been standardized.
The pharmacokinetics of acyclovir after oral administration have been evaluated in healthy volunteers and in immunocompromised patients with herpes simplex or varicella-zoster virus infection. Acyclovir plasma concentrations are higher in geriatric patients compared with younger adults, in part due to age-related changes in renal function. In general, the pharmacokinetics of acyclovir in pediatric patients is similar to that of adults.
Coadministration of probenecid with intravenous acyclovir has been shown to increase the mean acyclovir half-life and the area under the concentration-time curve. Herpes Zoster Infections: Acyclovir is indicated for the acute treatment of herpes zoster (shingles). Genital Herpes: Acyclovir is indicated for the treatment of initial episodes and the management of recurrent episodes of genital herpes. Acyclovir is contraindicated for patients who develop hypersensitivity to acyclovir or valacyclovir. Dosage adjustment is recommended when administering Acyclovir to patients with renal impairment (see DOSAGE AND ADMINISTRATION).
Patients are instructed to consult with their physician if they experience severe or troublesome adverse reactions, they become pregnant or intend to become pregnant, they intend to breastfeed while taking orally administered Acyclovir, or they have any other questions. Genital Herpes Infections: Patients should be informed that Acyclovir is not a cure for genital herpes. Safety and effectiveness of oral formulations of acyclovir in pediatric patients younger than 2 years of age have not been established.


Intravenous Acyclovir is indicated for the treatment of varicella-zoster infections in immunocompromised patients. Studies report alleviation of pain with oral acyclovir during the initial stages of the disease, especially if the drug is taken within the first three days of symptoms, and it may have a favorable effect on postherpetic neuralgia.
Oral agents for herpes zoster ophthalmicus should be administered as follows: Seventy-one nonimmunocompromised patients with herpes zoster ophthalmicus, presenting within seven days of onset of characteristic skin eruption, were enrolled in a prospective, longitudinal, randomized, double-masked, placebo-controlled trial with oral ac yclovir. To investigate the efficacy of valacyclovir on the shedding of HSV from genital mucosa, we compared the effect of valacyclovir and acyclovir on viral shedding in persons with recently acquired or frequently recurring genital HSV-2 infection. Acyclovir treatment of acute herpes zoster speeds rash healing and decreases pain and ocular complications. Herpes Zoster Infections: ZOVIRAX (acyclovir) is indicated for the acute treatment of herpes zoster (shingles).
Patient information about the treatment of herpes, chickenpox, or shingles is available with this medicine. The oral dose used to treat shingles is 800 mg taken five times a day for seven to ten days (until the rash has crusted over). Clinical isolates of HSV and VZV with reduced susceptibility to acyclovir have been recovered from immunocompromised patients, especially with advanced HIV infection. A dosage adjustment is recommended for patients with reduced renal function (see DOSAGE AND ADMINISTRATION).
Dosage reduction may be required in geriatric patients with underlying renal impairment (see PRECAUTIONS: Geriatric Use). Serial analyses of the 3-month recurrence rates for the patients showed that 71% to 87% were recurrence free in each quarter. Renal failure, in some cases resulting in death, has been observed with acyclovir therapy (see ADVERSE REACTIONS: Observed During Clinical Practice and OVERDOSAGE). Patients should be advised to initiate treatment as soon as possible after a diagnosis of herpes zoster. There are no data evaluating whether Acyclovir will prevent transmission of infection to others.
Plasma drug concentrations in animal studies are expressed as multiples of human exposure to acyclovir at the higher and lower dosing schedules (see CLINICAL PHARMACOLOGY: Pharmacokinetics).
A prospective epidemiologic registry of acyclovir use during pregnancy was established in 1984 and completed in April 1999.
No overall differences in effectiveness for time to cessation of new lesion formation or time to healing were reported between geriatric subjects and younger adult subjects.
This material is provided for educational purposes only and is not intended for medical advice, diagnosis or treatment. Poor systemic absorption has limited the, efficacy of early oral acyclovir in herpes zoster ophthalmicus (HZO). The recommended dosages for acyclovir, famciclovir and valacyclovir are provided in Table 1.
These events have been chosen for inclusion due to either their seriousness, frequency of reporting, potential causal connection to Acyclovir, or a combination of these factors.
If you have Herpes, you may already be familiar with Valtrex and Acyclovir, but aren’t sure which is the best for you.


Compared with acyclovir, valacyclovir may be slightly better at decreasing the severity of pain associated with herpes zoster, as well as the duration of postherpetic neuralgia. It treats cold sores around the mouth (caused by herpes simplex) , shingles (caused by herpes zoster) , and chickenpox. For the treatment of first episode genital herpes, the dose of oral acyclovir is 200 mg orally five times per day, or 400 mg orally three times per day (Table64.
Genital herpes can also be transmitted in the absence of symptoms through asymptomatic viral shedding. Valacyclovir (Valtrex) comparative analysis valacyclovir vs acyclovir, valacyclovir vs famciclovir. 5 mg per pound) of body weight, injected slowly into a vein over at least a one-hour period, and repeated every eight hours for five to ten days. Acyclovir is licensed in the United States for the treatment of initial episodes and management of recurrent episodes of genital herpes, for the treatment of chickenpox, and for the treatment of acute herpes zoster infections. The possibility of viral resistance to acyclovir should be considered in patients who show poor clinical response during therapy.
In patients greater than 50 years of age, valacyclovir 1 000 mg 3 times daily for 7 days or 14 days was compared to acyclovir 800 mg 5 times daily for 7 days. The pharmacokinetics of valacyclovir and acyclovir after oral administration of VALTREX (valacyclovir hydrochloride) have been investigated in 14 volunteer studies involving 283 adults and in 3 studies involving 112 pediatric subjects from 1 month to 12 years of age. Shingles requires treatment with higher doses of acyclovir, and the most common side effects at higher doses are tiredness and malaise.
Episodes of herpes zoster are generally self-limited and resolve without intervention; they tend to be more benign and mild in children than in adults. With respect to CNS adverse events observed during clinical practice, somnolence, hallucinations, confusion, and coma were reported more frequently in elderly patients (see CLINICAL PHARMACOLOGY, ADVERSE REACTIONS: Observed During Clinical Practice, and DOSAGE AND ADMINISTRATION). For treatment of Varicella zoster and Herpes zoster infections in adults: Zovirax is an antiviral medication that treats herpes infections caused by different types of herpes viruses. A meta-analysis of these data showed that acyclovir was significantly superior to placebo for reducing the duration of zoster-associated pain, defined as the continuum of pain measured from onset until final resolution. Herpes zoster (HZ) , also known as shingles, results from reactivation of VZV and its spread from a single ganglion to the neural tissue of the affected segment and the corresponding cutaneous dermatome 1. All patients with acute herpes zoster ophthalmicus should receive antiviral therapy with the goal of preventing ocular complications.
To compare the efficacy of one-year treatment with valacyclovir vs acyclovir in preventing recurrence of the herpes simplex virus (HSV) eye disease. Patients often have a clinical course of progressive deterioration and death, although anecdotal reports have suggested some benefit from high-dose intravenous acyclovir therapy 78, 79.
These clinical trials demonstrated that orally administered acyclovir, brivudin, famciclovir, or valacyclovir reduces the duration of viral shedding and new lesion formation and accelerates rash healing in patients with HZ.
