Valcivir

Uses of Valcivir

Valcivir is an antiviral medicine. It is used in the treatment of infections caused by herpes viruses, including genital herpes (a sexually transmitted infection), cold sores (small painful blisters around the mouth or other areas of the face), and shingles (viral infection that causes painful rashes or blisters on the skin). Valcivir works by slowing the growth of viruses. However, this medicine does not cure the infections but helps to reduce the symptoms (such as pain or itching) and decrease the severity of the condition. It also does not prevent you from spreading the viruses to others.

Before using this medication, tell your doctor or pharmacist your medical history, especially of: kidney problems, immune system problems.

This drug may rarely make you dizzy. Alcohol or marijuana (cannabis) can make you more dizzy. Do not drive, use machinery, or do anything that needs alertness until you can do it safely. Limit alcoholic beverages. Talk to your doctor if you are using marijuana (cannabis).

Older adults may be more sensitive to the side effects of this drug, especially mental/mood changes (such as confusion, agitation) and kidney problems (such as a change in the amount of urine).

Cold sores can spread easily. Avoid close physical contact with others (such as kissing) during an outbreak until the cold sores have completely healed. Try not to touch the cold sore. If you do, wash your hands afterward.

Valacyclovir does not prevent the spread of herpes. To lower the chance of giving genital herpes to your partner, do not have sexual contact during an outbreak or if you have symptoms. You can spread genital herpes even if you do not have symptoms. Always use an effective barrier method (latex or polyurethane condoms/dental dams) during all sexual activity. Consult your doctor or pharmacist for more details.

During pregnancy, this medication should be used only when clearly needed. Discuss the risks and benefits with your doctor.
