Terms & Conditions of Program
A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.
The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.
Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.
Your doctor may prescribe Valtrex to treat or prevent different viral infections. Valtrex belongs to a class of medications called antivirals.
Valtrex is primarily given to treat infection with different types of herpes viruses. Specifically, it can be used to treat cold sores, genital herpes, and herpes zoster (shingles). It can also be taken every day to prevent viral infections in people with HIV whose immune systems are compromised.
Valtrex works by preventing herpes viruses from replicating and making new viruses. It attaches to viral DNA to prevent the infection from spreading further. This slows down the infection enough for the immune system to contain the infection.
The amount you should take will be determined by the doctor and depends on what you are treating.
For cold sores, the normal dose is 2 grams every 12 hours for one day.
For the first outbreak of genital herpes, take 1 gram twice daily for ten days.
For subsequent outbreaks of genital herpes, take 500 mg twice daily for three days.
For viral suppression, the normal dose is 500 mg by mouth once daily.
Take each dose of Valtrex with a full glass of water.
The active ingredient in Valtrex generic is Valacyclovir.
