Valtrex Medication

Generic Valtrex overview

Valtrex, also known as Valacyclovir, or Valaciclovir, is a prodrug with antiviral effect. It means that it is not biologically active itself, but its metabolites are the acyclovir and others, having powerful antiviral mechanisms that prevent development of herpes in such forms as herpes B, herpes simplex and herpes zoster (shingles). The drug was discovered in 1982, and soon become a popular antiviral solution. In 2009, the patent has expired, and generic Valtrex was introduced: cost of Valacyclovir in generic form is affordable, while the compound and effect is equal to the brand drug.

Valacyclovir medication usages

Indications for the Valacyclovir therapy include treatment and prophylaxis of herpes simplex (its oral and genital forms), herpes zoster, infectious mononucleosis, and several other cases, particularly to help patients with weakened immune system (during chemotherapy or organ transplantation). Generic Valtrex effectively fights herpes B and cytomegalovirus, so it is often prescribed in these conditions. Usually, people order Valtrex online with no prescription for self-medication purposes, because this drug is relatively safe and easy to use on your own. In any case, we recommend consulting your doctor before trying any therapy, to make it most effective and safe.

Mechanism of action

Valacyclovir is a form of well-known acyclovir, which is a powerful antiviral drug. Valacyclovir has much higher bioavailability (55% and more) than the original drug (10-15%). After the oral intake of Valtrex, the medication quickly metabolizes into acyclovir, and its action takes effect by inhibiting the DNA polymerase of the viral cells. It has approximately 100 times stronger effect on viral cells than on body cells in this case: preventing the division and multiplication of herpes virus, acyclovir is effectively metabolized in human cells, and excreted from the body. One of the most convenient antiviral drugs, cheap Valtrex has become very popular: people order Valtrex online and it cures them from herpes thanks to the effective mechanism of action.
