It is used to treat a viral What does antiviral drugs do Having safe sex to prevent sexually transmitted infections (STIs) may seem like a no-brainer. But we also understand the very real stigma that comes with an STI like herpes.Herpes is caused by two viruses: the herpes simplex virus type 1 (HSV-1 or cold sores) and the herpes simplex virus type 2 (HSV-2 or genital herpes). This STI is actually very common, with over 500,000 new infections in 2018 in the U.S. alone.The bad news is that there’s no cure for herpes. The good news is that consistent treatment can manage the severity of herpes outbreaks.Plus, various treatment options are available, including Valtrex® — or valacyclovir, the generic version — an antiviral medication.So what is valacyclovir? Can this medication be used to stop a cold sore? Are there adverse effects, and if so, how long do Valtrex side effects last?Dealing with herpes and starting a new medication can be overwhelming. We’re here to answer the above questions and go over other key information about valacyclovir.Is valacyclovir an antibiotic or another type of medication? And is there a difference between the Valtrex- the brand-name medication, and valacyclovir- the generic name medication?Valacyclovir is an antiviral drug designed to manage HSV (herpes simplex virus), shingles (herpes zoster) and VZV (varicella-zoster virus, more commonly known as chickenpox) infections.As mentioned above, valacyclovir is Valtrex’s generic name — this medication is available under a few different brand names.But you don’t have to worry about generic versus brand-name medication. Generic drugs are required by the FDA (U.S. Food and Drug Administration) to be the same dosage, safety, effectiveness, strength and quality as their brand-name counterparts.Valacyclovir is an extremely well-studied medication prescribed to people of all ages. It’s been widely and successfully used to control and treat the symptoms of HSV-1 and HSV-2. This medication is so effective, in fact, it’s listed as the “gold standard” in herpes treatment studies.Now that you know what this medication is, you might be wondering: How does valacyclovir work?We mentioned that valacyclovir is an antiviral drug, meaning the medication fights infections caused by viruses. With that said, valacyclovir isn’t classified as an antibiotic — antibiotics are medications that help the immune system fight infections caused by bacteria, not viruses.Like many medications, valacyclovir works through a complex chemical process that interferes with how the herpes virus reproduces. In other words, it stops the herpes virus from spreading to healthy cells, reducing the effects of the virus.The drug slows down the growth of herpes, making it easier for the body to control the infection. Valacyclovir itself is a prodrug (meaning it converts into another substance in the body). It converts into acyclovir (another antiviral herpes medication) after it passes through the liver.Comparing valacyclovir versus acyclovir, Macrolide antibiotics such as Zithromax (azithromycin); Antivirals What does prednisone do?

Valtrex vs. Famvir: What's the difference?Valtrex (valacyclovir) and Famvir (famciclovir) are antiviral drugs used to treat infections with shingles (herpes zoster), genital herpes (herpes simplex genitalis), and cold sores (herpes labialis).Side effects of Valtrex and Famvir that are similar include headache, nausea, vomiting, reduced white blood cells, diarrhea, and rash.Side effects of Valtrex that are different from Famvir include abdominal pain, cold symptoms, increased liver enzymes, joint pain, and dizziness.Side effects of Famvir that are different from Valtrex include fatigue, flatulence, allergic reactions, serious skin reactions, yellowing skin and eyes (jaundice), abnormal liver function tests, and reduced platelets (thrombocytopenia).What is Valtrex? What is Famvir? Valtrex (valacyclovir) is an antiviral medication used to treat shingles (herpes zoster), genital herpes (herpes simplex genitalis), and cold sores (herpes labialis). Valtrex is a nucleoside analog that mimics a building block of DNA and stops the spread of herpes virus in the body by preventing the replication of viral DNA necessary for viruses to multiply. Other nucleoside analogs include acyclovir (Zovirax) and famciclovir (Famvir). Valacyclovir is a "prodrug," that in itself is not active. It is converted to acyclovir in the body and it is the acyclovir that is active against the viruses. (Acyclovir is available as a topical, oral, and intravenous medication.) Valacyclovir is active against the same viruses as acyclovir, but it has a longer duration of action than acyclovir and may be taken fewer times each day.Famvir (famciclovir) is an antiviral drug active against the Herpes viruses, including herpes simplex 1 and 2 (cold sores and genital herpes) and varicella-zoster (shingles and chickenpox). It is a nucleoside analog that mimics one of the building blocks of DNA. It stops the spread of herpes virus in the body by preventing the replication of viral DNA that is necessary for viruses to multiply. Other nucleoside analogs include acyclovir (Zovirax) and valacyclovir (Valtrex). Famvir is actually a "prodrug," that is, not active directly against viruses. Instead, Famvir is converted to penciclovir in the body, and it is the penciclovir that is active against the viruses. Famvir is active against the same viruses as acyclovir but has a longer duration of action so it can be taken fewer times each day. Famvir does not cure or stop the spread of herpes infections. Famvir relieves pain, burning, itching, and tingling, and also heals and prevents sores associated with herpes infections.
