    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.

    Many women at increased risk for breast cancer could benefit from preventive therapy. Preventive therapy options for breast cancer risk reduction have expanded in the last few years to include both selective receptor modulators (tamoxifen and raloxifene) and aromatase inhibitors (anastrozole and exemestane). Risk factors that place women at high risk for breast cancer, as well as risk calculation models appropriate for the selection of candidates for preventive therapy, are presented, followed by a review of current guidelines for chemoprevention and results of chemoprevention trials. The modified Gail model or Breast Cancer Risk Assessment Tool is the most widely utilized risk assessment calculator to determine eligibility for chemoprevention. Women most likely to benefit from preventive therapy include those at high risk under the age of 50 years and those with atypical hyperplasia. Physician and patient barriers limit widespread acceptance and adherence to preventive therapy. Published guidelines on chemoprevention for breast cancer have been updated to increase awareness and encourage discussion between patients and their physicians regarding evidence-based studies evaluating the benefits of preventive options for women at increased risk for breast cancer.
