Uses of Valtrex

Valtrex is also known by the generic name Valacyclovir

USES:
Valacyclovir is used in children to treat cold sores (herpes labialis) and chickenpox (varicella zoster). It is used in adults to treat cold sores and shingles (herpes zoster). Valacyclovir does not cure these diseases, but it may decrease pain and help sores heal faster. Valacyclovir belongs to a class of medications known as antivirals.

Valacyclovir is also used to treat people with genital herpes who are currently having an outbreak. It can also be used to prevent an outbreak (suppressive therapy). This medication helps control symptoms, but does not cure the disease or prevent infection of sexual partners.

If you are taking valacyclovir for treatment of genital herpes, it is important to follow safe sex practices to lower the chance of giving herpes to your partner, even if there are no symptoms present. Always use a condom made of latex or polyurethane. When you have symptoms or are experiencing an outbreak, do not have sexual contact with your partner.

Uses of Famciclovir

USES:
Famciclovir is used to treat infections caused by certain types of viruses. It treats shingles caused by herpes zoster. It also treats outbreaks of herpes simplex that cause cold sores around the mouth, sores around the anus, and genital herpes. In people with frequent outbreaks of genital herpes, famciclovir is used to help reduce the number of future episodes.

Famciclovir is an antiviral drug. However, it is not a cure for these infections. The viruses that cause these infections continue to live in the body even between outbreaks. Famciclovir decreases the severity and length of these outbreaks. It helps the sores heal faster, keeps new sores from forming, and decreases pain/itching. This medication may also help reduce how long pain remains after the sores heal. In addition, in people with a weakened immune system, famciclovir can decrease the risk of the virus spreading to other parts of the body and causing serious infections.
