Acyclovir Treatment for Shingles

People who have had chicken pox can contract shingles. Though anyone can come down with shingles, it's most common in adults older than 50. Acyclovir is a prescription drug that treats patients with shingles and other viruses. It's the generic version of the name-brand drug Zovirax and, like other antiviral pills, should be prescribed by a doctor.

  1. How Does It Work?

    • Viruses take over healthy cells in the body and then reproduce more infected cells. Acyclovir attacks the infected cells and stops them from reproducing. The drug was approved by the FDA in March 1982.

    Effects of Acylovir

    • Acyclovir can reduce the pain associated with shingles. It helps lesions heal faster and lessens nerve pain as well. Studies show that Acyclovir is most effective when taken within 48 hours of infection.

    Common Side Effects

    • As with all drugs, it's possible for some people who take acyclovir to have side effects, including nausea or vomiting, diarrhea, headaches and a general ill feeling.

    Serious Side Effects

    • More serious side effects are not frequently seen, but they are possible. They include agitation, hallucinations, unusual bruising or bleeding, seizures, decrease in frequency of urination, and signs of allergic reaction (unexplained rash, hives, itching, swelling). If any of these symptoms occur, consult a doctor immediately.

    Precautions

    • People who are pregnant or nursing, have kidney disease or are allergic to any food, dyes or preservatives should discuss these conditions with a doctor before taking acyclovir.
