Valtrex: An Antiviral Drug

Valtrex is usually used in the treatment of infections in both adults and children. It mainly aims to prevent the reoccurrence of future episodes from viral infections. You cannot use Valtrex as a cure for these infections, as these viruses continue to inhabit the host`s body in between the outbreaks. Valtrex is mainly used to reduce the length of time of these outbreaks as well as the severity of each of these outbreaks. Valtrex is mainly used in treated herpes virus related infections in children and adults. Valtrex may be used as a treatment of chickenpox, caused by a virus known as varicella zoster, in children over the age of two and as a treatment of cold sores which are cause by herpes simplex in children over the age of twelve years.

How Valtrex Works: Valtrex uses an active ingredient that is broken down in the body to form another compound that prevents the herpes virus from reproducing. This will thereby prevent the infection of more cells of the body. This active compound works by moving into cells that have been infected with the herpes virus and block the action of a chemical called DNA polymerase. This is an enzyme that is used by the herpes virus to change its genetic coding from what is known as RNA to DNA. This limits the viruse`s ability to change the DNA structure of any other of the body`s cell limiting its ability to multiply. Valtrex is used in those who have had a kidney transplant. This is because when you have a transplant done you are usually given drugs that weaken your immune system to prevent your body from attacking the newly transplanted organ. This will make you susceptible to attacks from a virus known as cytomegalovirus or CMV.

Valtrex Dosage: You should take Valtrex as recommended by your doctor. Valtrex can be taken with or without food and you need to take it with a full glass of water. Shake the suspension well before you measure it.
