    Valacyclovir dosage for herpes zoster


    Valacyclovir works best if it is used within 48 hours after the first symptoms of shingles or genital herpes (e.g., pain, burning, or blisters) begin to appear. For recurrent outbreaks of genital herpes, valacyclovir works best if it is used within 24 hours after the symptoms begin to appear. If you are taking valacyclovir for the treatment of chickenpox, it is best to start taking valacyclovir as soon as possible after the first sign of the chickenpox rash appears, usually within one day. Valacyclovir may be taken with meals or on an empty stomach. If you are using the oral suspension, use a specially marked measuring spoon or other device to measure each dose accurately. The average household teaspoon may not hold the right amount of liquid. Drink extra fluids so you will pass more urine while you are using this medicine. 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.

    Valacyclovir belongs to the class of medications known as antivirals. It is used to treat a viral infection affecting the skin known as shingles (herpes zoster). It is also used to treat cold sores, and to treat and prevent recurrences of genital herpes. It works by interfering with the way the virus reproduces. Valacyclovir works by stopping the virus from multiplying and spreading to nearby healthy cells. It does not cure shingles, cold sores, or genital herpes, but it does help the sores to heal more quickly, and it relieves pain and discomfort. When used to prevent recurrences of herpes, it also reduces the risk of transmission (spreading) of the infection to others. 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.

    Many of us have become so accustomed to seeing the “avoid alcohol” warning on every new prescription we get that we’ve begun to tune out this advice…and few of us even consider that alcohol might react with over-the-counter (OTC) medications. Alcohol is a powerful drug that has widespread and sometimes unpredictable effects in the body. It makes some medications less effective…amplifies the effects of others…and can cause a toxic—or even fatal—reaction with some medications. Below, some medications that are adversely affected by alcohol…* Acetaminophen (Tylenol) by itself can be harmful to the liver—in fact, acetaminophen overdose is the number-one cause of acute liver failure. But the likelihood of liver failure is much greater if you also drink alcohol. Why acetaminophen and alcohol don’t mix: Alcohol is a toxin, but there’s a reaction in the body that breaks apart alcohol molecules so they are less dangerous. This reaction requires a coenzyme called NAD (nicotinamide adenine dinucleotide) that’s found in all living cells. However, we also need NAD to deal with the toxic effects of acetaminophen.
