Common Use

Valtrex is an antiviral medication used to treat specific herpes infections, such as herpes zoster (shingles), genital herpes, and cold sores on the face and lips. It works by stopping viral replication, slowing down the herpes virus, and helping the body's natural defenses to limit the duration and frequency of outbreaks. While Valtrex does not cure herpes, it effectively reduces the symptoms of the infection.

Dosage and Direction

Consult your doctor before using Valtrex. Take it orally with or without food, as prescribed. For herpes zoster, take it every 8 hours (3 times daily) for one week. For genital herpes, take it twice daily for 5 days. Cold sores typically require only one day of treatment. For optimal results, begin treatment as soon as symptoms appear.

Precautions

Valtrex should not be used by individuals with immune system issues, HIV infection, or those who have undergone bone marrow or kidney transplants, as it may pose life-threatening risks. When taken daily in appropriate doses, Valtrex can reduce the risk of transmitting genital herpes to sexual partners. Combine its use with safer sex practices for maximum effectiveness. Avoid using Valtrex during pregnancy, while planning to become pregnant, or while breastfeeding without medical advice.

Contraindications

Valtrex is not recommended for individuals with kidney disease, blood disorders, or hypersensitivity to any of its components.
