Famvir (famciclovir) is an antiviral medication prescribed for treating infections caused by herpes viruses, including shingles, cold sores, and genital herpes. It functions by inhibiting viral replication, thereby alleviating symptoms and accelerating the healing process. Available in tablet form (125 mg, 250 mg, and 500 mg), it’s usually taken with or without food as prescribed by a doctor.
Famvir is mainly recommended for adults, with dosage adjustments for seniors based on kidney function. Common side effects include headache or nausea. If you miss a dose, take it when you remember, but don’t double up. To ensure authentic and reliable delivery, you can order Famvir online, safely sourced from licensed Canadian pharmacies.

Famvir functions by preventing the herpes virus from replicating within the body. Once taken, it’s converted into its active form, which interferes with the virus’s ability to multiply. This helps control the infection, easing symptoms like pain, itching, and burning. While it doesn’t cure herpes or stop it from spreading to others, it can speed up healing and reduce the chance of new sores forming.
Common Famvir side effects may include:
Serious Famvir side effects (rare) may include:
Note: Contact your medical provider if you experience any serious symptoms or unusual side effects.
