Warnings Of Acyclovir And Valacyclovir
Both acyclovir and valacyclovir are contraindicated in patients with a history of hypersensitivity to either drug. Cautions should also be used if a patient has had a previous reaction to famciclovir, ganciclovir, penciclovir, or valganciclovir as there is a chance for cross-sensitivity between these drugs.
Acyclovir and valacyclovir should also be used cautiously in patients with renal dysfunction. Dose adjustments may be necessary to avoid central nervous system toxicity. Signs of CNS toxicity include agitations, hallucinations, confusion, and delirium. These are more likely in the elderly population. Good hydration is necessary to avoid precipitation of the drugs in the tubules of the kidneys.
What Is Feline Herpes
Feline herpes is caused by feline herpesvirus type 1 , also known scientifically as feline viral rhinotracheitis . This virus infects cats and uses the cats own cells to make more of the virus. Because of this, herpesvirus is very challengingif not impossibleto treat.
Once herpesvirus has infected a cat, most cats will be infected with the virus for a lifetime, including inside cells of the nervous system . During times of stress, cats will develop symptoms again and again.
Medication For Feline Herpes
When cats are not very active, are very congested, or have a lot of yellow-green discharge from the eyes or nose, your veterinarian may prescribe antibiotics. This will eliminate any secondary bacterial infections. Antibiotics will also often shorten the course of disease.
Depending on your cats symptoms, your veterinarian may prescribe either antibiotics by mouth or into the eye. The best choice of antibiotics by mouth for an upper respiratory infection include doxycycline and azithromycin. Some choices of antibiotics in the eyes include erythromycin, Terramycin, tobramycin, or ofloxacin.
While antibiotics may help shorten the length of time your kitty is feeling ill, they will not treat the virus itself. A very common antiviral medication taken by mouth in cats to kill herpesvirus is called famciclovir. It has limited side effects and is most often used when cats have one of the more uncommon conditions, such as keratitis, stomatitis or dermatitis. It may also be used when cats have chronic symptoms related to herpes such as chronic congestion or eye infection.

Is Acyclovir Or Valacyclovir More Effective
Acyclovir and valacyclovir were compared in the treatment of first episodes of genital herpes infections in an international double-blind, randomized trial. Acyclovir was dosed five times daily, and valacyclovir was dosed only twice daily. It found no clinically significant difference in the lesion healing time, duration of pain, or time to loss of all symptoms. Given that, valacyclovir offers the advantage of twice-daily dosing. This decreases pill burden and increases the likelihood that patients will take the regimen as prescribed until completion. Your doctor will determine what is best to treat a genital herpes infection, but twice-daily dosing may offer an advantage for valacyclovir.
In another randomized, double-blind clinical trial, acyclovir and valacyclovir oral tablet doses were compared for a herpes zoster infection, otherwise known as shingles. The results of this study showed valacyclovir significantly accelerated the resolution of pain associated with a shingles rash. While the rash itself resolved in similar times with either treatment regimen, there were fewer ocular complications in those treated with valacyclovir. Another significant advantage for valacyclovir in this study is that it only needed to be dosed three times per day as compared to five times per day for acyclovir. Ultimately, only your prescriber can determine which treatment option is best for you with an active herpes zoster infection.

Drug Interactions Of Acyclovir Vs Valacyclovir
Acyclovir and valacyclovir are known to have negative effects on both the kidneys and the liver. For this reason, both drugs may be dangerous to take with drugs that are also nephrotoxic or hepatotoxic. In some cases, the risk is so severe that the concurrent use with these drugs is contraindicated. This is the case with cidofovir. Other drugs are strongly discouraged from being used concomitantly with acyclovir or valacyclovir for the same concerns. These include capreomycin, foscarnet, and mannitol.
Vaccinations against varicella and zoster have significantly decreased outbreaks of these viruses. However, the administration of live attenuated vaccines depend on the bodys immune system and natural response to the vaccine to produce antibodies in order to be effective. For that reason, acyclovir and valacyclovir should not be administered within a specific window before and after administering these vaccines. Your healthcare provider can provide more specific information prior to your vaccine.
This is not intended to be a comprehensive list of all potential drug interactions. Please ask your doctor or pharmacist for more information and be sure they know all prescription drugs and supplements you are taking prior to beginning antiviral therapy.

How Do Herpes Drugs Work
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. 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. 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. People with active HSV-1 or HSV-2 infections can take them during outbreaks to control and treat their symptoms. Antiviral drugs are also used as part of suppressive therapy for herpes to reduce the severity and frequency of outbreaks.
Even people with asymptomatic herpes can benefit from using antiviral drugs to lower their risk of spreading the virus to other people through sexual or oral contact.
Why Is This Medication Prescribed
Acyclovir is used to decrease pain and speed the healing of sores or blisters in people who have varicella , herpes zoster , and first-time or repeat outbreaks of genital herpes . Acyclovir is also sometimes used to prevent outbreaks of genital herpes in people who are infected with the virus. Acyclovir is in a class of antiviral medications called synthetic nucleoside analogues. It works by stopping the spread of the herpes virus in the body. Acyclovir will not cure genital herpes and may not stop the spread of genital herpes to other people.

What Are The Main Differences Between Acyclovir Vs Valacyclovir
Acyclovir is a prescription medication used in the treatment of herpes simplex virus and varicella-zoster virus . It belongs to a class of antiviral drugs known as synthetic purine deoxynucleoside analogues. This class is also sometimes referred to as nucleoside and nucleotide DNA polymerase inhibitor antivirals. Acyclovir fights viral infections by incorporating itself into the viral DNA and then prohibiting viral DNA synthesis. Acyclovir is available in a variety of forms including topical cream and ointment, ophthalmic ointment, solution for injection, oral capsules, oral tablets, oral dissolving tablets, and oral suspension. The oral acyclovir formulation has poor bioavailability because it is altered in first-pass metabolism, resulting in poor absorption from the gastrointestinal tract.
