What Are Antiviral Medications For Herpes

Treatment For Genital Herpes

There are three antiviral medications that are FDA-approved for the treatment of genital herpes:

  • Acyclovir: The oldest antiviral medication for herpes is acyclovir. It has been available since 1982 in a topical form and sold since 1985 in pill form. Acyclovir has been shown to be safe in persons who have used it continuously for as long as 10 years.
  • Valacyclovir: A newer drug, valacyclovir, actually uses acyclovir as its active ingredient. This medication delivers acyclovir more efficiently so that the body absorbs much of the drug, which has the advantage of taking the medication fewer times during the day.
  • Famciclovir: Famciclovir uses penciclovir as its active ingredient to stop HSV from replicating. Like valacyclovir, it is well absorbed, persists for a longer time in the body, and can be taken less frequently than acyclovir.

Antiviral medication is commonly prescribed for patients having a first episode of genital herpes, but they can be used for recurrent episodes as well. There are two kinds of treatment regimens: episodic therapy and suppressive therapy.

Where Can I Get Medications For Herpes

The most common antiviral medications used to manage herpes simplex symptoms are available by prescription. If you have symptoms such as a cold sore or genital herpes, call your doctors office. They will first diagnose if you have herpes simplex. Then they will prescribe an appropriate medication to manage your symptoms.

Only docosanol is an antiviral medication available over the counter as a cream to manage oral symptoms such as cold sores or fever blisters.

If you have mild symptoms from a recurring oral herpes infection, you may be able to use nonprescription methods or some home remedies to manage your symptoms.

Examples include:

  • pain relievers such ibuprofen or acetaminophen to help with pain
  • cold compress or ice to soothe burning or itching
  • zinc oxide topical cream, which may help soothe itching or burning

Before trying over the counter medications or supplements, be sure to talk with your doctor or pharmacist about your symptoms.

Binding And Entry Inhibition

Other antiviral drugs act on the host cell to inhibit the virus . The advantage to this approach is that resistance to the drug is less likely to appear, especially because these drugs are not subject to TK activation and ACV resistance mutations in that locus while random mutations occur in both viruses and hosts, the mutation rate in viruses is much higher than it is in host cells . On the other hand, targeting a host cell function may lead to higher toxicity, potentially limiting therapeutic use to only viral strains that are resistant to safer therapies.

Who Can And Cannot Take Aciclovir

Aciclovir can be taken by most adults and children.

Aciclovir is not suitable for some people.

To make sure aciclovir is safe for you, tell your doctor if you:

  • have had an allergic reaction to aciclovir or any other medicine in the past
  • have kidney problems
  • are over 65 years old
  • are pregnant, trying to get pregnant or breastfeeding

If your immune system is weakened , talk to your doctor about the best type of aciclovir for you.

They may recommend tablets rather than the cream.

What Other Information Should I Know

Influenza and Herpes Simplex Antivirals

Keep all appointments with your doctor and the laboratory. Your doctor may order certain lab tests to check your response to acyclovir.

Do not let anyone else take or use your medication. Ask your pharmacist any questions you have about refilling your prescription.

It is important for you to keep a written list of all of the prescription and nonprescription medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.

Avoid The Following While You Are Using Acyclovir Buccal Delayed

  • Do not chew gum, touch, or press the buccal tablet after it has been applied.
  • Do not wear upper dentures.
  • Do not brush your teeth until it dissolves. If your teeth need to be cleaned while the tablet is in place, rinse the mouth gently.

Shake the suspension well before each use to mix the medication evenly.

Your symptoms should improve during your treatment with acyclovir. Call your doctor if your symptoms do not improve or if they get worse.

Take or use acyclovir until you finish the prescription, even if you feel better. If you stop taking acyclovir too soon or skip doses, your infection may not be completely treated or may become more difficult to treat. The delayed-release buccal tablet is applied as a one-time dose.

What Are The Best Natural Remedies For Herpes

When experiencing a herpes outbreak, one of the most important things someone can do is keep the area clean, cool, and dry, since heat and dampness can irritate the sores. Maintaining a healthy immune system can go a long way too, according to Dr. Hayag. “A strong, healthy immune system can keep herpes under control, prevent outbreaks, and reduce the duration of symptoms,” she says. “Supplements like zinc, vitamin C, and echinacea are vital to increasing your immune function and easy to incorporate into your daily routine.” And when it comes to natural remedies, there are several that can provide much-needed relief.

What Is The Best Medication For Herpes

The effectiveness of a particular medication varies depending on the person, so there’s no single “best” herpes treatment. Doctors prescribe the most suitable drug for each patient’s condition, medical history, and current medications. That said, here are a few of the drugs most commonly used to treat HSV:

  • Redness
  • Swelling

This doesn’t encompass the full scope of potential side effects, just the most common ones. Anyone considering treatment with one of these medications should speak with a healthcare professional for a more comprehensive list.

Side Effects And Follow

Pharmacology of Antivirals (Hep C, Herpes)

Side effects with these herpes drugs are considered mild, and health experts believe these drugs are safe in the long term. Acyclovir is the oldest of the three, and its safety has been documented in people taking suppressive therapy for several years.

People taking suppressive therapy should see their doctor at least once a year to decide if they should continue. You may find taking the pills every day to be inconvenient, the drugs may not work for you, or you may naturally have fewer outbreaks as time goes on. Your doctor can help you make treatment choices to suit your needs.

Other Uses For This Medicine

Acyclovir is also sometimes used to treat eczema herpeticum to treat and prevent herpes infections of the skin, eyes, nose, and mouth in patients with human immunodeficiency virus , and to treat oral hairy leukoplakia .

This medication may be prescribed for other uses ask your doctor or pharmacist for more information.

Treatment Of Primary Infection

Antiviral therapy is recommended for an initial genital herpes outbreak, especially if the patient has systemic symptoms or is immunocompromised.2 Oral acyclovir is effective in reducing symptoms1 . Intravenous administration may be required in immunocompromised patients and those with severe disseminated infection.1 Topical acyclovir reduces the duration of viral shedding and the length of time before all lesions become crusted, but this treatment is much less effective than oral or intravenous acyclovir.1

Statistics About Herpes Simplex Virus

Herpes simplex virus in immunocompetent people is rarely resistant to Acyclovir . But in immunocompromised people 3.5% to 10% of herpes simplex cases are resistant to Acyclovir. In clinical surveys researchers report of up to 36% of cases of herpes simplex that are resistant to Acyclovir. You can see that an alternative treatment against herpes involving smaller molecules that treats regular herpes and also resistant herpes would be very useful.

Dr. Evilevitch is doing research together with the National Institutes of Health in the United States in order to develop an oral medication that will treat resistant herpes.

How Should This Medicine Be Used

Herpes Treatment

Acyclovir comes as a tablet, a capsule, and a suspension to take by mouth. It also comes as a delayed-release buccal tablet to apply to the upper gum of the mouth. The tablets, capsules, and suspension are usually taken with or without food two to five times a day for 5 to 10 days, starting as soon as possible after your symptoms begin. When acyclovir is used to prevent outbreaks of genital herpes, it is usually taken two to five times a day for up to 12 months. The delayed-release buccal tablet is usually applied with a dry finger as a one-time dose within 1 hour after itching, redness, burning or tingling cold sore symptoms begin but before the cold sore appears. Take or use acyclovir at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take or use acyclovir exactly as directed. Do not take or use more or less of it or take it more often or for a longer time than prescribed by your doctor.

Do not chew, crush, suck, or swallow the delayed-release buccal tablets. Drink plenty of liquids, if you have a dry mouth while using the delayed-release buccal tablets.

How Do Hsv Antivirals Work

Pharmacology 879 a AntiViral Drugs Viral Classification Non RetroVirus Herpes Influenza Hepatitis

Herpes simplex virus antivirals are used to treat herpes simplex virus 1 and 2 . Acyclovir is the antiviral most commonly used to treat HSV infections. It works by inhibiting DNAsynthesis and therefore prevents replication of the virus. HSV-1 is transmitted by oral-to-oral contact, mainly causes oral herpes known as cold sores, and may also cause genital herpes. HSV-2 is a sexually transmitted disease that causes genital herpes. Herpes infections are highly contagious oral and genital herpes is usually asymptomatic, and if symptomatic, painful blisters or ulcers appear at the site of infection. HSV-2 infection increases the risk of acquiring and transmitting human immunodeficiency virus infection.

Acyclovir is converted into acyclovir monophosphate by viral thymidine kinase enzyme, which is then converted into acyclovir triphosphate by the hostcell kinases. The formed ACV-TP competitively inhibits and inactivates HSV DNA polymerase and prevents viral DNA synthesis and replication of the virus.

How Is Genital Herpes Treated

Genital herpes is an infection caused by the herpes simplex virus . The virus causes an outbreak of blisters which are common herpes symptoms. Treatment is with antiviral medication to help prevent and control outbreaks.

If youre unsure if you have herpes, you can take a genital herpes test at home.

There are 3 main types of treatment for genital herpes:

Aciclovir tablets are used for outbreaks of genital herpes or cold sores to treat the symptoms. They can also be used to prevent outbreaks from happening if you get them often. How much you take and how long you take them for can vary depending on what youre using it for whether youre using it to treat an outbreak or to prevent future outbreaks.

Valaciclovir tablets are known as a pro-drug, which means your body converts it into aciclovir after you take them. Like aciclovir tablets, they can be used to treat symptoms or to prevent outbreaks.

A doctor may prescribe famciclovir tablets if you find that aciclovir or valaciclovir havent worked for you.

Treatment Of Common Cutaneous Herpes Simplex Virus Infections

DAVID H. EMMERT, M.D., Lancaster General Hospital, Lancaster, Pennsylvania

Am Fam Physician. 2000 Mar 15 61:1697-1704.

Herpes simplex virus infection is increasingly common in the United States. New antiviral medications have expanded treatment options for the two most common cutaneous manifestations, orolabial and genital herpes. Acyclovir therapy remains an effective and often less expensive option. Famciclovir and valacyclovir offer improved oral bioavailability and convenient oral dosing schedules but are more expensive than acyclovir. Patients who have six or more recurrences of genital herpes per year can be treated with one of the following regimens: acyclovir, 400 mg twice daily valacyclovir, 1 g daily or famciclovir, 250 mg twice daily. These regimens are effective in suppressing 70 to 80 percent of symptomatic recurrences. Episodic treatment of recurrent genital herpes is of questionable benefit, but it may be helpful in appropriately selected patients. There is little evidence indicating benefit from treatment of recurrent orolabial herpes, which tends to be mild and infrequent.

Zovirax Side Effects List For Healthcare Professionals

Adverse Drug Reaction Overview

The most frequent adverse reactions associated with the use of Zovirax are headache and nausea.

Neurological side effects have also been reported in rare instances. Elderly patients and patients with a history of renal impairment are at increased risk of developing these effects. In the reported cases, these reactions were generally reversible on discontinuation of treatment.

Clinical Trial Adverse Drug Reactions

Because clinical trials are conducted under very specific conditions the adverse reaction rates observed in the clinical trials may not reflect the rates observed in practice and should not be compared to the rates in the clinical trials of another drug. Adverse drug reaction information from clinical trials is useful for identifying drug-related adverse events and for approximating rates.

Treatment of Herpes Simplex

Short-term administration : The most frequent adverse reactions reported during clinical trials of treatment of genital herpes with oral Zovirax in 298 patients are listed in Table 1.
