    Valtrex dosage for children


    Several antiviral agents are available to treat viral illnesses in healthy children. In some children, treatment with acyclovir is an alternative to vaccination for the treatment and prevention of chickenpox. Acyclovir also can be useful in the treatment or prevention of herpes simplex infections in neonates. Ribavirin, once recommended as routine therapy for high-risk infants with respiratory syncytial virus disease, is now reserved for use in selected children. Amantadine and rimantidine are effective against influenza type A and can be used to protect children from influenza, as well as to lessen the duration and severity of illness in those who are already ill. Viral infections in neonates, infants and children range from the common cold to the extremely rare, but deadly, herpes simplex meningitis. Although not much can be done to prevent or treat colds, antiviral agents can shorten the duration of some viral diseases. 24 hours after lesion onset) Suppressive therapy (immunocompetent patients): 1 g/day PO Suppressive therapy (immunocompetent patients with ≤9 recurrences annually): 500 mg/day PO; transmission reduction for source partner, 500 mg/day PO Suppressive therapy (HIV-infected patients): 500 mg PO q12hr Thrombotic thrombocytopenic purpura (TTP)/hemolytic uremic syndrome (HUS) reported in patients with advanced HIV disease and in allogenic bone marrow transplant and renal transplant recipients Acute renal failure (ARF) may occur, especially in elderly patients or those with underlying renal impairment receiving higher than recommended doses; use with caution in patients with renal impairment, the elderly, and/or patients receiving nephrotoxic drugs Treatment should begin with the earliest symptom (tingling, burning, itching) in cold sores; for genital herpes, it should begin at the first signs and symptoms (within 72 hours of onset of first diagnosis or 24 hours of onset of recurrent episodes); for herpes zoster, it should begin within 72 hours of onset of rash; for chicken pox, it should begin with the earliest sign or symptom Central nervous system (CNS) effects may occur (eg, agitation, hallucinations, confusion, encephalopathy); risk of CNS adverse effects is higher in elderly patients Adequately hydrate patient; decreased precipitation in renal tubules may occur Metabolized by liver; valacyclovir is rapidly and nearly completely converted to acyclovir and L-valine via first-pass effect; acyclovir is hepatically metabolized to a very small extent by aldehyde oxidase and by alcohol and aldehyde dehydrogenase (inactive metabolites) The above information is provided for general informational and educational purposes only.

    Cold sores are painful and oozing, and they always seem to appear before that wedding or class reunion. Cold sores are typically caused by type 1 virus (HSV-1). Also called fever blisters, the small, fluid-filled lesions typically form near or on your lips and can cause symptoms such as tingling, itching, or burning. But in some cases, HSV-1 can cause sores on the genitals and type 2 virus (HSV-2) can cause sores on the mouth. But, because they’re caused by a virus, they can be treated with antiviral medications. Valtrex, which contains the active ingredient valacyclovir, can help your cold sores clear up faster. It can also reduce the number of cold sores you get. 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. Most people don’t require treatment for their cold sores, but, in some cases, a doctor may prescribe an antiviral medication such as Valtrex. The dose in immunocompromised patients is 1000 mg three times daily for at least seven days (3000 mg total daily dose) and for 2 days following crusting of lesions. This dose should be reduced according to creatinine clearance (see Renal impairment below). For recurrent episodes, treatment should be for three to five days. For initial episodes, which can be more severe, treatment may have to be extended to ten days. For recurrent episodes of herpes simplex, this should ideally be during the prodromal period or immediately upon appearance of the first signs or symptoms. Valtrex can prevent lesion development when taken at the first signs and symptoms of an HSV recurrence. For herpes labialis (cold sores), valaciclovir 2000 mg twice daily for one day is effective treatment in adults and adolescents. The second dose should be taken about 12 h (no sooner than 6 h) after the first dose.
