Sometimes it gets you, and there's not a lot you can do.

Took the 1g every 12 hours plus icing the areas, and it wasn't enough to stop it. • Acyclovir is the active drug while valaciclovir is the pro-drug. Hoping it heals quickly though so that I can see my boyfriend! Once the drug enters the body the viral enzyme called thymidine kinase converts it to acyclovir monophosphate. Only 1% of the patients who receive acyclovir experiences adverse drug effects.

The culprit is the varicella-zoster virus. It should be started as soon as possible after symptom onset and only needs to be taken twice a day.... Acyclovir is almost completely broken down by the liver when taken orally, whereas valacyclovir has an oral bioavailability level of approximately 50 percent compared to approximately 12 percent for oral acyclovir. Unlike valacyclovir and acyclovir, which are usually prescribed for HSV-1 and HSV-2, famciclovir is typically used to treat shingles, or herpes zoster. For Cold Sores: I take valacyclovir 500mg once a day. Valtrex mimics a building block of DNA and stops the spread of herpes virus in the body by preventing the viral DNA replication necessary for viruses to multiply. MedicineNet does not provide medical advice, diagnosis or treatment. Usually don't have any cold sores anymore. It won't cure the disease, but it'll shorten the length of a breakout. I've found that valtrex isn't useful because it's a delayed-release formula. It stops the spread of herpes virus in the body by preventing the replication of viral DNA that is necessary for viruses to multiply.

It was shown that valacyclovir has similar efficacy to acyclovir in the episodic and suppressive treatment of genital herpes. Valtrex (valacyclovir) is an antiviral drug used to treat shingles (herpes zoster) and genital herpes (herpes simplex genitalis) infections, and cold sores (herpes labialis). • Valaciclovir is more bioavailable than acyclovir… This final product blocks DNA replication and viral reproduction. There are several drugs used to treat herpes, all of which are antiviral medications. However, consistent use of an antiviral drug can make living with herpes much easier by speeding up healing after an outbreak and reducing your risk of transmitting the virus to other people.Herpes drugs are taken for several reasons. This does not necessarily mean no interactions exist. Both Valtrex® and Famvir® effectively accelerate resolution of zoster rash, lessen the severity of acute pain, and reduce duration of post-herpetic neuralgia. Finally, I explained to a doctor how often I was getting outbreaks and how bad they were, and they prescribed 200mg of acyclovir a day as a suppressant. In this guide, comparing valacyclovir vs. acyclovir vs. famciclovir to explain which one is the best choice for treating and managing the virus.Herpes medications like valacyclovir, acyclovir and famciclovir belong to a class of medications called antiviral drugs.Antiviral drugs are designed to inhibit the multiplication  of viruses in the body.

Side effects of Valtrex and Famvir that are similar include headache, nausea, vomiting, reduced white blood cells, diarrhea, and rash.What's going on down there? • Valaciclovir is more bioavailable than acyclovir.• Valacyclovir is more effective when given orally than acyclovir. Valtrex (valacyclovir) may cost more also. Unlike antibiotics, which eliminate the bacteria that cause infections, antiviral drugs simply control viral proliferation, rather than completely eliminating the target virus from the body.None of the antiviral drugs on the market today can cure herpes.
