Famciclovir 250mg (Famtrex 250)

What is Famciclovir 250mg?

Famciclovir 250mg is an antiviral agent used for the treatment of infections due to the herpes virus such as herpes zoster, genital herpes and oral herpes. The key dosage of the substance is 250 mg and it is used in different dosing schedules depending on the type of the treatment and the patient’s condition. Famciclovir belongs to the class of prodrugs and this means that in the body it is transformed into the active substance – penciclovir. Penciclovir, once it has been activated, exerts it antiviral activity through the competitive inhibition of viral DNA polymerase. It zeros in the viral enzyme DNA polymerase as a way through which the virus is able to replicate and hence spread within the body. By preventing the interrupting of this process, famciclovir is useful in preventing the occurrence of sever and prolonged herpes outbreak.

Herpes Zoster (Shingles): Famtrex 250 mg is used in the treatment of shingles with the aim of minimizing the pain and shortening the time that is taken to heal the blisters. It is best administered when begun 72 hours post emergence of the rash.

Genital Herpes: Thus, in recurrent genital herpes, famciclovir can reduce the length of an episode, decrease the signs and symptoms, and decrease the chances of passing the virus to another.

Cold Sores: Famtrex 250mg is also used occasionally for cold sores (herpes labialis), and reduces the healing time.
