Why is this medication prescribed?
Aciklovir is used to decrease pain and speed the healing of sores or blisters in people who have varicella (chickenpox), herpes zoster (shingles; a rash that can occur in people who have had chickenpox in the past), and first-time or repeat outbreaks of genital herpes (a herpes virus infection that causes sores to form around the genitals and rectum from time to time). Aciklovir is also sometimes used to prevent outbreaks of genital herpes in people who are infected with the virus. Aciklovir is in a class of antiviral medications called synthetic nucleoside analogues. It works by stopping the spread of the herpes virus in the body. Aciklovir will not cure genital herpes and may not stop the spread of genital herpes to other people.

What Is Aciklovir (Zovirax)?
Aciklovir is the generic name for Zovirax, a prescription medication used to treat certain virus infections.
The Food and Drug Administration (FDA) approved Aciklovir to treat viral infections from the varicella virus that causes chicken pox and shingles, as well as infections from the virus that causes genital herpes.
Sometimes doctors prescribe Aciklovir to treat herpes infections in people with HIV.
The drug works by preventing viruses from dividing and multiplying. The FDA approved Aciklovir in the 1980s.
Aciklovir is available as a generic, made by several companies, or under the brand name Zovirax, made by GlaxoSmithKline and available in tablet, capsule, and liquid form.
Aciklovir is one of the oldest drugs used to treat herpes simplex viruses and remains the first line of treatment for these infections.
However, research shows that Aciklovir is not as effective as it used to be.
A 2013 study, published in the journal Current Opinion in Infectious Diseases, found that Aciklovir-resistant herpes strains could develop over time.
Resistance happens in people with a healthy immune system as well as in those with a weakened immune system.
Take Aciklovir for the entire length of time prescribed by your doctor. Your symptoms may get better before the infection is completely treated.
Treatment with Aciklovir should be started as soon as possible after the first appearance of symptoms (such as tingling, burning, blisters).
Herpes infections are contagious and you can infect other people, even while you are being treated with Aciklovir. Avoid letting infected areas come into contact with other people. Avoid touching an infected area and then touching your eyes. Wash your hands frequently to prevent passing the infection to others.

Why it's used

This drug doesn't cure herpes infections. The herpes virus can stay in your body for a long time and cause symptoms again later.
What Is Aciklovir (Zovirax) and How Does It Work?
Aciklovir is approved by the Food and Drug Administration as a prescription drug that is commonly used as a topical, injectable, and oral treatment for genital herpes and cold sores. Herpes refers to a group of viruses that cause a variety of herpes infections including genital herpes, shingles, chicken pox (also chickenpox), cold sores, and encephalitis (inflammation of the brain). Herpes viral infections are very common. Genital herpes refers to a sexually transmitted disease (STD) that any sexually active person can contract and transmit.
Shingles and chicken pox are common skin conditions.Shingles and chicken pox are skin infections which are both caused by the herpes virus. They are not caused by the same virus that causes cold sores or genital herpes.
Many people who suffer from shingles or chicken pox (chickenpox) infection will experience symptoms such as a rash, often with pain, which is treatable with this drug.
Genital herpes is an STD caused by two types of viruses: herpes simplex type 1 and herpes simplex type 2. Most people with genital herpes do not know they have it. Still, symptoms often appear days to weeks after exposure. Symptoms of genital herpes generally include:
- Flu-like symptoms such as fever, body aches, or swollen glands
- Blisters, sores, or rash in the genital area with or without pain, itching, tingling
- Blisters that pop open, causing painful sores.
Aciklovir may also help treat pain associated with an outbreak of genital herpes after the sores heal.
There is no cure for herpes, however, this prescription is a treatment that helps to decrease and ease symptoms of herpes infections.
Aciklovir is am antiviral drug that belongs to a class of medications called "antivirals," or "antiviral medications."
Your doctor may prescribe this drug as a treatment to relieve symptoms of your infection.
This medication is similar to the drug valAciklovir (Valtrex), which is another medication that may also be prescribed for herpes infections.
This drug may cause serious side effects or mild side effects. This includes side effects that may affect the liver. Side effects that affect the skin as well as allergic reactions have occurred.
Aciklovir is the generic equivalent of Zovirax.
