How Effective Are Medications For Herpes

Prescription antiviral medications have proven effectiveness in managing HSV symptoms.

A 2017 study comparing the antiviral medications acyclovir, famciclovir, penciclovir and valacyclovir to treat herpes simplex labialis found all antiviral medications were effective to shorten healing time for lesions and reducing pain. The comparison study found valacyclovir had the fastest healing time and pain reduction.

Precautions Before Taking Aciclovir

  • Are you pregnant or breast-feeding?
  • Do you have any kidneys problems?
  • Have you ever had a seizure ?
  • Are you taking any other medicines? This includes any medicines you buy without a prescription, such as herbal and complementary medicines.

If you answered yes to any of these questions, its important that you tell your doctor before you start taking aciclovir. Sometimes a medicine isnt suitable for a person with certain conditions or it can only be used with extra care.

Other Types Of Antivirals

There are several different kinds of antiviral agents that are prescribed to fight viral skin infections. These medications can be divided into systemic antivirals and topical antivirals. Systemic antivirals are usually given orally in pill form. However, they sometimes may be administered intravenously .This is most likely in situations where the patient is suffering from a suppressed immune system , is unable to swallow oral medication, has impaired memory or mental capacity or does not have quick access to a hospital should complications arise during drug therapy.

Systemic Antivirals

famciclovir

Famvir

Topical antivirals are usually available in various forms, including creams, ointments, gels, patches and sprays. In addition, most topical antivirals can be further subdivided into one of three major classes:

  • Cytodestructive drugs
  • Immunoenhancing drugs
  • Viricidal drugs

Management Of Sex Partners

Herpes Treatment

The sex partners of persons who have symptomatic genital herpes can benefit from evaluation and counseling. Symptomatic sex partners should be evaluated and treated in the same manner as patients who have symptomatic genital herpes. Asymptomatic sex partners of patients who have symptomatic genital herpes should be asked about a history of genital symptoms and offered type-specific serologic testing for HSV-2. For partners without genital herpes, no data are available on which to base a recommendation for PEP or PrEP with antiviral medications or that they would prevent acquisition, and this should not be offered to patients as a prevention strategy.

Occasionally, herpes simplex virus can cause burning skin sensations, deep aches or sudden twinges in the genital area. When they occur in the thighs or buttocks, they are sometimes compared to sciatica. These symptoms are called prodromes or prodromal symptoms. They are a sign that the virus is trying to reactivate and there may be virus on the skin surface. Sometimes sores will follow, but very often your immune response overcomes the virus before visible signs appear.

Cautions With Other Medicines

Some medicines can affect the way aciclovir tablets or liquid work. They can also make you more likely to get side effects.

If you’re using aciclovir cream on your skin, this is less likely to react with other medicines.

It’s important to tell your doctor if you take any of the following medicines before taking aciclovir:

  • cimetidine, a medicine for stomach ulcers
  • mycophenolate mofetil, a medicine given after organ transplants
  • probenecid, a medicine for gout
  • aminophylline or theophylline, medicines for asthma

How Effective Are Topical Herpes Treatments

Studies have found that topical creams and ointments like and arent so great at preventing lesions from oral herpes . Theyre also really expensive and usually have to be applied several times a day.

Two new topical medications for oral herpes may hold more promise, but they come at a cost.

  • includes acyclovir 5% cream and 1% hydrocortisone and works better than either ingredient alone. Interestingly, Xerese cream has been shown not only to shorten healing time but also to make it less likely that the lesions will return. Unfortunately, Xerese is expensive and rarely covered by insurance. But it is a combination of 2 cheaper generic creams, so talk to your doctor about making your own combination.

  • is a different form of acyclovir that can also be used to treat an oral herpes outbreak. It is an adhesive tablet that you place on your gums. Sitavig delivers a high concentration of acyclovir directly to your lip, the site of the cold sore. But again, itll cost you.

Treatment Of Herpes Zoster

Pharmacology – ANTIVIRAL DRUGS (MADE EASY)

The treatment of herpes zoster has three major objectives: treatment of the acute viral infection, treatment of the acute pain associated with herpes zoster and prevention of postherpetic neuralgia. Antiviral agents, oral corticosteroids and adjunctive individualized pain-management modalities are used to achieve these objectives.

How Is Herpes Diagnosed

The herpes virus is almost always spread through sexual intercourse, oral sex, or kissing. Although sometimes HSV-1 can spread via shared lip balm, utensils, or other items that come in contact with saliva.

In most cases, healthcare providers can diagnose herpes with a visual examination and by discussing various symptoms. If there’s any doubt, they can take a viral culture to confirm, which involves lab analysis of a swab or scraping.

“If the patient has no history of herpes simplex and is a new patient, I always do a viral culture,” says , MD, a board-certified dermatologist and founder of 5th Avenue Aesthetics. “Also, if I am suspicious of HSV-2 or if it is an immunocompromised patient, I will order a viral culture. I start treatment right away before results come back. These results can take one week and it is best to start treatment early.”

But again, symptoms aren’t always present. Fortunately, it’s also possible to diagnose HSV with a blood test. Your body produces antibodies to combat viruses, and doctors can use a blood sample to detect the specific antibodies that fight the herpes simplex virus.

A primary care physician can perform the examinations and tests necessary for an accurate diagnosis. However, sexual health clinics offer similar, reliable services.

Other Antiviral Agents Used In Herpes Infections

Valaciclovir is a prodrug of aciclovir and has better bioavailability. It can also be used to treat HSV and HZV. It is used to prevent CMV infection following an organ transplant. Usual doses are:

Suppressive Therapy For Recurrent Hsv

Suppressive therapy reduces frequency of genital herpes recurrences by 70%80% among patients who have frequent recurrences . Persons receiving such therapy often report having experienced no symptomatic outbreaks. Suppressive therapy also is effective for patients with less frequent recurrences. Long-term safety and efficacy have been documented among patients receiving daily acyclovir, valacyclovir, and famciclovir . Quality of life is improved for many patients with frequent recurrences who receive suppressive therapy rather than episodic treatment . Providers should discuss with patients on an annual basis whether they want to continue suppressive therapy because frequency of genital HSV-2 recurrence diminishes over time for many persons. However, neither treatment discontinuation nor laboratory monitoring is necessary because adverse events and development of HSV antiviral resistance related to long-term antiviral use are uncommon.

Valacyclovir 500 mg orally 2 times/day for 3 daysOR

Valacyclovir 1 gm orally once daily for 5 days

*Acyclovir 400 mg orally 3 times/day is also effective, but are not recommended because of frequency of dosing.

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.
