Acyclovir (oral) is a antiviral agent that is FDA approved for the treatment of herpes zoster, genital herpes, and chickenpox. Chronic Suppressive Therapy for Recurrent Disease: 400 mg 2 times daily for up to 12 months, followed by re-evaluation.
Acyclovir is indicated for the treatment of initial episodes and the management of recurrent episodes of genital herpes. 800 mg every 4 hours orally, 5 times daily for 7 to 10 days for treatment of initial genital herpes. Intravenous acyclovir is indicated for the treatment of varicella-zoster infections in immunocompromised patients.
When therapy is indicated, it should be initiated at the earliest sign or symptom of chickenpox. There is limited information regarding Off-Label Guideline-Supported Use of Acyclovir in adult patients. There is limited information regarding Off-Label Guideline-Supported Use of Acyclovir in pediatric patients. Acyclovir is contraindicated for patients who develop hypersensitivity to acyclovir or valacyclovir. Dosage adjustment is recommended when administering acyclovir to patients with renal impairment. 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.
There are no data on treatment initiated more than 72 hours after onset of the zoster rash.
Chickenpox in otherwise healthy children is usually a self-limited disease of mild to moderate severity. The most frequent adverse event reported during 3 clinical trials of treatment of herpes zoster (shingles) with 800 mg of oral acyclovir 5 times daily for 7 to 10 days in 323 patients was malaise (11.5%).
In addition to adverse events reported from clinical trials, the following events have been identified during post-approval use of acyclovir.
Aggressive behavior, agitation, ataxia, coma, confusion, decreased consciousness, delirium, dizziness, dysarthria, encephalopathy, hallucinations, paresthesia, psychosis, seizure, somnolence, tremors.
Alopecia, erythema multiforme, photosensitive rash, pruritus, rash, Stevens-Johnson syndrome, toxic epidermal necrolysis, urticaria. Renal failure, renal pain (may be associated with renal failure), elevated blood urea nitrogen, elevated creatinine, hematuria.
The data presented below include references to peak steady-state plasma acyclovir concentrations observed in humans treated with 800 mg given orally 5 times a day (dosing appropriate for treatment of herpes zoster) or 200 mg given orally 5 times a day (dosing appropriate for treatment of genital herpes). Coadministration of probenecid with acyclovir has been shown to increase the mean acyclovir half-life and the area under the concentration-time curve. There is no Australian Drug Evaluation Committee (ADEC) guidance on usage of Acyclovir (oral) in women who are pregnant. Safety and effectiveness of oral formulations of acyclovir in pediatric patients younger than 2 years of age have not been established.
Of 376 subjects who received acyclovir in a clinical study of herpes zoster treatment in immunocompetent subjects ? 50 years of age, 244 were 65 and over while 111 were 75 and over. There is no FDA guidance on the use of Acyclovir (oral) with respect to specific gender populations.
There is no FDA guidance on the use of Acyclovir (oral) with respect to specific racial populations. There is no FDA guidance on the use of Acyclovir (oral) in patients with hepatic impairment. There is no FDA guidance on the use of Acyclovir (oral) in women of reproductive potentials and males. There is no FDA guidance one the use of Acyclovir (oral) in patients who are immunocompromised. For patients who require hemodialysis, the mean plasma half-life of acyclovir during hemodialysis is approximately 5 hours. Acyclovir suspension was shown to be bioequivalent to acyclovir capsules (n = 20) and 1 acyclovir 800 mg tablet was shown to be bioequivalent to 4 acyclovir 200 mg capsules (n = 24).
There is limited information regarding the compatibility of Acyclovir (oral) and IV administrations. Acyclovir is a synthetic purine nucleoside analogue with in vitro and in vivo inhibitory activity against herpes simplex virus types 1 (HSV-1), 2 (HSV- 2), and varicella-zoster virus (VZV).
The inhibitory activity of acyclovir is highly selective due to its affinity for the enzyme thymidine kinase (TK) encoded by HSV and VZV.
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. There is limited information regarding Acyclovir (oral) Pharmacodynamics in the drug label. 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.
In one multiple-dose, crossover study in healthy subjects (n = 23), it was shown that increases in plasma acyclovir concentrations were less than dose proportional with increasing dose, as shown in Table 2.
There was no effect of food on the absorption of acyclovir (n = 6); therefore, acyclovir capsules and tablets may be administered with or without food.
Acyclovir plasma concentrations are higher in geriatric patients compared to 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. There is limited information regarding Acyclovir (oral) Nonclinical Toxicology in the drug label. Double-blind, placebo-controlled studies have demonstrated that orally administered acyclovir significantly reduced the duration of acute infection and duration of lesion healing. In a study of patients who received acyclovir 400 mg twice daily for 3 years, 45%, 52%, and 63% of patients remained free of recurrences in the first, second, and third years, respectively. In a double-blind, placebo-controlled study of immunocompetent patients with localized cutaneous zoster infection, acyclovir (800 mg 5 times daily for 10 days) shortened the times to lesion scabbing, healing, and complete cessation of pain, and reduced the duration of viral shedding and the duration of new lesion formation.
Treatment was begun within 72 hours of rash onset and was most effective if started within the first 48 hours. Three randomized, double-blind, placebo-controlled trials were conducted in 993 pediatric patients aged 2 to 18 years with chickenpox.
There is limited information regarding Acyclovir (oral) Look-Alike Drug Names in the drug label. Acyclovir is the generic name for Zovirax, a prescription medication used to treat certain virus infections.
Acyclovir is available as a generic, made by several companies, or under the brand name Zovirax, made by GlaxoSmithKline and available in tablet, capsule, and liquid form. Resistance happens in people with a healthy immune system as well as in those with a weakened immune system.
It's important to know that treatment with acyclovir works best when you start taking it as soon as possible after a rash appears. It's usually not necessary to treat young, healthy children with chicken pox, but older children or adults who get chicken pox may need treatment. Use acyclovir with caution if you have kidney disease or any condition that weakness your immune system. Researchers have not studied acyclovir use by pregnant women, so there's not enough evidence to say that it is safe to take during pregnancy.
The most common side effects of acyclovir treatment for genital herpes include nausea, vomiting, and diarrhea.


Shingles requires treatment with higher doses of acyclovir, and the most common side effects at higher doses are tiredness and malaise. Some drugs may affect the way acyclovir works, and acyclovir may affect other drugs you are taking. It's very important to let your doctor know about all drugs you are taking, including any over-the-counter herbs or supplements. If you think that you or someone else has overdosed, call a poison control center at 1-800-222-1222.
Skipping doses or stopping too soon may not completely treat your infection, or it could make the infection harder to treat.
Q: Can you please tell me if there are any long-term side effects to taking 800mg of acyclovir each day? A: Acyclovir (Zovirax) is an antiviral medication indicated for the acute treatment of herpes zoster (shingles), the treatment of initial episodes and the management of recurrent episodes of genital herpes and the treatment of chickenpox. The dosage and administration of oral acyclovir depends upon the indication for use and age of the patient. The most frequently reported adverse reactions differed among clinical trials of acyclovir depending on the indication for use. For the treatment of shingles, there is no information regarding initiation of treatment more than 72 hours following the onset of rash. For the treatment of chickenpox, information gathered during clinical studies reflects initiation of treatment within 24 hours following rash. Patients should be advised that acyclovir is not a cure for genital herpes and there is no available research regarding whether acyclovir will prevent the transmission of the virus to other individuals. A: The most frequently reported side effects of acyclovir (Zovirax), for oral administration, differed in clinical trials depending on the indication for use. During clinical trials of treatment with long-term administration with acyclovir for genital herpes, there were two methods of administration evaluated. The most frequently reported adverse reaction during clinical trials of shingles was malaise.
Lastly, during clinical trials of treatment of chickenpox with acyclovir, the most frequently reported adverse reaction was diarrhea.
Patients are instructed to consult with their health care provider if they experience any other unusual, severe or troublesome side effects while being treated with acyclovir. For the management of genital herpes, patients should be instructed regarding appropriate dosage and administration of acyclovir ointment. During controlled clinical trials, mild pain, including temporary burning and stinging, was reported in approximately 30% of patients with no significant difference between patients receiving Zovirax ointment and patients receiving placebo. A: How long acyclovir (Zovirax) treatment is intended for depends upon the indication for use. For the treatment of initial episodes of genital herpes, the length of acyclovir treatment is 10 days.
For the management of recurrent episodes of genital herpes, there were two methods of administration of acyclovir treatment evaluated in clinical trials. For the treatment of chickenpox for adults and children, the recommended length of acyclovir treatment is 5 days. A: During post marketing experience, observed in clinical practice, acyclovir (Zovirax) was reported to cause hair loss. Other adverse reactions reported during post marketing experience with acyclovir included headache, allergic reaction, fever, pain, swelling in the extremities, agitation, confusion, dizziness, somnolence, tremors, diarrhea, gastrointestinal distress, nausea, anemia, leucopenia, thrombocytopenia, elevated liver enzymes, hepatitis, jaundice, myalgia, prutitus, rash, visual disturbances, kidney failure, kidney pain, elevated blood urea nitrogen (BUN) and creatinine, and hematuria. According to the prescribing information for Zovirax, the brand-name of acyclovir, the most frequently reported adverse reactions reported during clinical trials included nausea, vomiting, diarrhea, malaise and headache and varied depending on the indication for treatment. Patients are instructed to contact their health care provider, immediately, if they experience symptoms which may indicate more serious adverse reactions of acyclovir have developed. It is important for patients to report any unusual or bothersome reactions they experience while being treated with acyclovir. Some of the other possible acyclovir interactions with other medications may include Demerol (meperidine), Dilantin (phenytoin), Cellcept (mycophenolate mofetil), Viread (tenofovir), Zanaflex (tizanidine), Depakene (valproic acid), Retrovir (zidovudine), theophyllines and the varicella virus vaccine. It is essential for patients to consult with their health care provider regarding all prescription and over the counter medications they take prior to initiation of treatment with acyclovir to avoid potentially dangerous drug interactions. A: During clinical trials, patients did not report acyclovir (Zovirax) causing stomach pain. Other common adverse reactions possible with acyclovir treatment include headache and malaise. It is essential for patients to consult a health care provider if they experience any unusual or bothersome adverse reactions while being treated with acyclovir for further evaluation.
Acyclovir may be taken without regard to food and should be taken exactly as instructed by a health care provider.
A: Shingles is a painful rash that is caused by the same virus (varicella virus) that causes the chickenpox. A: Acyclovir (Zovirax) is an antiviral medication that can be used in the treatment of the herpes virus, including genital herpes, cold sores, and shingles.

WikiDoc is not a professional health care provider, nor is it a suitable replacement for a licensed healthcare provider. Alternative regimens have included doses ranging from 200 mg 3 times daily to 200 mg 5 times daily. After 1 year of therapy, the frequency and severity of the patient’s genital herpes infection should be re-evaluated to assess the need for continuation of therapy with acyclovir. There is no information about the efficacy of therapy initiated more than 24 hours after onset of signs and symptoms. 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.
Because they are reported voluntarily from a population of unknown size, estimates of frequency cannot be made. These symptoms may be marked, particularly in older adults or in patients with renal impairment (see PRECAUTIONS). 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). There was no statistically significant difference in the incidence of tumors between treated and control animals, nor did acyclovir shorten the latency of tumors. In the mouse study, plasma levels were 9 to 18 times human levels, while in the rat study, they were 8 to 15 times human levels. Testicular atrophy and aspermatogenesis were observed in rats and dogs at higher dose levels.
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 results in a 60% decrease in plasma concentrations following a 6 hour dialysis period. Adverse events that have been reported in association with overdosage include agitation, coma, seizures, and lethargy.


Sensitivity testing results, expressed as the concentration of drug required to inhibit by 50% the growth of virus in cell culture (IC50), vary greatly depending upon a number of factors. 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. Each opaque blue cap and body size #1 hard gelatin capsule is imprinted with black ink N 940 and 200 on opposing cap and body portion of the capsule.
Each blue colored, biconvex, capsule shaped, compressed unscored tablet is debossed with N943 on one side and 400 on the other side. Each white to off-white colored, biconvex, capsule shaped, compressed unscored tablet is debossed with N947 on one side and 800 on the other side. Genital herpes spreads through sexual activity, and taking acyclovir alone may not be enough to prevent it.
People older than 65 may have more side effects from acyclovir because their kidneys do not get rid of the drug as quickly as younger people's do.

Treatment was initiated within 24 hours of the typical chickenpox rash in the controlled studies, and there is no information regarding the effects of treatment begun later in the disease course. 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. Maximum plasma concentrations were 3 to 6 times human levels in the mouse bioassay and 1 to 2 times human levels in the rat bioassay. These exposures resulted in plasma levels 9 and 18, 16 and 106, and 11 and 22 times, respectively, human levels. There were 749 pregnancies followed in women exposed to systemic acyclovir during the first trimester of pregnancy resulting in 756 outcomes. Therefore, the patient’s dosing schedule should be adjusted so that an additional dose is administered after each dialysis. The monophosphate is further converted into diphosphate by cellular guanylate kinase and into triphosphate by a number of cellular enzymes. While most of the acyclovir-resistant mutants isolated thus far from immunocompromised patients have been found to be TK-deficient mutants, other mutants involving the viral TK gene (TK partial and TK altered) and DNA polymerase have been isolated. In addition, each capsule contains the following inactive ingredients: corn starch, lactose monohydrate, magnesium stearate and sodium lauryl sulfate. There have been rare (less than 1 percent of studied patients) that have had suspected effects on various organ systems such as liver, kidneys, heart, etc. The last 3 summers I have had attacks of shingles, the 1st year I took 1000 mg of acyclovir daily and avoided the painful stage. Unfortunately, people with weakened immune systems, from other diseases like cancer or treatments like chemotherapy, are at much greater risk of developing shingles.

Overdosage has been reported following bolus injections or inappropriately high doses and in patients whose fluid and electrolyte balance were not properly monitored. As always, talk with your health care provider regarding questions you have about side effects of your prescription medications.
Last year I missed the spots as they were on my back and suffered greatly for 2 to 3 months and I am still taking 1000 mg acyclovir per day.
Neither Everyday Health nor its licensors endorse drugs, diagnose patients or recommend therapy. If medical management of a genital herpes recurrence is indicated, patients should be advised to initiate therapy at the first sign or symptom of an episode. However, the small size of the registry is insufficient to evaluate the risk for less common defects or to permit reliable or definitive conclusions regarding the safety of acyclovir in pregnant women and their developing fetuses. Elderly patients are more likely to have reduced renal function and require dose reduction. This is accomplished in 3 ways: 1) competitive inhibition of viral DNA polymerase, 2) incorporation into and termination of the growing viral DNA chain, and 3) inactivation of the viral DNA polymerase.
The possibility of viral resistance to acyclovir should be considered in patients who show poor clinical response during therapy. A search of the prescribing information for Acyclovir did not specifically list uncontrollable muscle twitching as a side effect.
Each time I stop the medication the fever returns for a couple of days followed by the first few spots. Acyclovir should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. In the event of acute renal failure and anuria, the patient may benefit from hemodialysis until renal function is restored. The greater antiviral activity of acyclovir against HSV compared to VZV is due to its more efficient phosphorylation by the viral TK. Treatment with acyclovir did not affect varicella-zoster virus-specific humoral or cellular immune responses at 1 month or 1 year following treatment. I am on my 5th lot of acyclovir, starting with 1000 mg per day, increasing to 2,400 per day and 2 weeks ago was prescribed 4000 mg per day for 21 days.
The absence of a warning for a given drug or drug combination in no way should be construed to indicate that the drug or combination is safe, effective or appropriate for any given patient. I have managed 10 days at this level but there are so many side effects, including kidney pain, so I have reduced to 3 tablets of 800 mg each.
