    Valacyclovir dosage for shingles


    This article explains the differences between Valacyclovir and Acyclovir, two antiviral medications that are used to treat cold sores around the mouth and shingles. Shingles, also known as herpes zoster, is a common viral infection which is caused by the varicella-zoster virus. About 33 percent of people will develop herpes zoster in their lifetime, with approximately 1 million cases every year in the US. This virus is actually the same virus that causes chickenpox. The symptoms of this condition generally affect only a small section of one side of the body. These symptoms may include: Valtrex is the brand name for this antiviral drug. It works by slowing the growth and spread of the virus, thus, the body can fight off the infection. In 1995, it was approved for medical use and is manufactured by Glaxo Smith Kline, a British pharmaceutical company with headquarters in London. In the United States, it is available as a generic drug since 2009. 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.
