This page discusses prescription antiviral medications that have been approved by the FDA for the treatment of colds sores (fever blisters). The mode of action associated with prescription antiviral medications is one where they are used to interfere with herpes virus replication (the production of more virus particles, called virions). In comparison, once a lesion has reached the Blister stage (the point of maximum viral presence) or beyond, an antiviral will have no practical effect because the stages involving the bulk of virus production have already passed.
Even when a lesion is being treated with an antiviral, the risk of transmission of the herpes virus to others, or to other parts of your own body, remains and therefore precautions should still be taken. Topical medicines for cold sores are those that are applied as an ointment or cream directly to the surface of the lesion. Denavir® cream was the first antiviral medication to be granted FDA approval for use in the treatment of cold sores. Its instructions state that it should be applied repeatedly throughout the day every 2 waking hours (roughly 9 times a day) for 4 days on those external areas of the lips or face where the cold sore is forming. Zovirax® cream received FDA approval for use in the treatment of cold sores in late 2002, although other formulations of this medication have been used in treating herpes for many years (including an "off-label" use in the treatment of cold sores in the years prior to 2002).
The cream is applied to the area where the cold sore is forming 5 times per day, for 5 days. The idea with this product is that the steroid component helps to stifle the extent of the inflammation reaction that takes place in response to the presence of the virus particles and the destruction they have caused.
We think that the answer to this question is best answered by your health care professional.
A study by Hull (2014) evaluated the use of an acyclovir (5%) and hydrocortisone (1%) cream (Xerese®). Opstelten (2008) reviewed 10 studies that had evaluated the use of acyclovir cream (found in Zovirax®). This same literature review stated that two penciclovir studies (the compound found in Denavir®) reported findings that were similar as those for acyclovir. We found three studies (Femiano 2001, Lin 2002, McKeough 2001) that each studied the head-to-head effectiveness of acyclovir cream (the compound found in Zovirax®) and penciclovir cream (the compound found in Denavir®) in the treatment of cold sores.
Historically, oral antiviral medications have not routinely been used in the treatment of cold sores. Depending on the practitioner, it may be that these medicines are more likely prescribed in situations where there's a history of especially severe or disfiguring lesions, cases involving newborn babies or immunocompromised patients. As with all other antiviral approaches, starting the medication as early as possible (during the Tingle stage) is key for effectiveness. All prescription medications should only be used under the direction and supervision of a health care professional. This is a viral infection of the lips and mouth which is caused by the herpes simplex virus a€“ termed HSV. Herpes doesna€™t always develop symptoms a€“ it does not always cause any outward, visible signs.
Kissing or touching and any sexual contact with the area that is infected spreads oral herpes.
Many individuals have symptoms of itching, burning, and tingling proceeding the outbreak of blisters or sores. The most concentrated pain from these sores occurs at the onset and can make drinking or eating hard. If a child with cold sores is less than 6 weeks old, the babya€™s physician needs to be notified if oral blisters or sores appear. Individuals with weakened immunity systems should also notify their primary care physician if sores or blisters appear. A physician will make a tentative diagnosis on data provided by the patient and on the physician exam. Topical anesthetic such as lidocaine (xylocaine, Nervocaine, Dilocaine, Zilactin-L) can be approved for pain relieve of oral blisters and lesions. Oral or IV drugs exist for HSV but only for individuals with weakened immune systems, infants younger than 6 weeks or those with severe disease. Topical Denavir (penciclovir) creams can shorten attacks of recurrent HSV-if it is applied early, normally before lesions develop.
These medications may stop viral reproduction in the skin but do not eradicate HSV from the body or stop later outbreaks. This website is for informational purposes only and Is not a substitute for medical advice, diagnosis or treatment.
Herpes simplex virus infects an individual’s mucous membrane and skin, and creeps through the pathway of the nerves to reach the nerve clusters.
The virus, as mentioned, can be transmitted by contracting body fluids from the infected individual. When the virus successfully destroys the cell that is hosting it while replicating, the initial symptoms will occur, such as tingling sensation, inflammation and the appearance of cold sores or fever blisters on the skin. This type of herpes condition occurs within the genital areas and its surrounding areas, such as the buttocks and thighs.
Oral herpes or non-genital herpes normally affect the lips and mouth of the infected individual. Although the virus is not life threatening, cases of death are reported due to the condition as well.
During a sexual intercourse, it is necessary to use protection and avoid contacting individuals with weakened immune system, such as kids, diabetics and elderly.

Herpes simplex encephalitis after brain surgery: case report and review of the literature -- Spuler et al.
The polymerase chain reaction has revolutionised the diagnosis of herpes simplex encephalitis. Herpes simplex virus (HSV) infections are ubiquitous and have a wide range of clinical manifestations (see the images below). These drugs may stop viral replication in the skin but do not eliminate HSV from the body or prevent later outbreaks (HSV reactivation).
Herpes gladiatorum (mat herpes) is a skin infection caused by herpes simplex virus type 1 (HSV-1) , the same virus that causes cold sores on the lips.
A 36-year-old female presented to the Emergency Treatment Center (ETC) of the University of Iowa Hospitals and Clinics (UIHC) with one day of right eye pain, photophobia and decreased vision. The following day, her symptoms did not resolve and was therefore referred to the UIHC Cornea service for further evaluation. During the first ten days of treatment, all subjective symptoms resolved with the exception of mild blurring of vision. She returned for routine follow-up one month after discontinuation of topical corticosteroids.


HSV keratitis can present with involvement of the corneal epithelium, stroma, or endothelium, with or without associated inflammation of the anterior chamber (Table 1).[1-4] Pathophysiologic manifestations may be related to the presence of live virus, immunological reactions to viral antigen, or secondary to previous herpetic injury ("metaherpetic"), particularly the loss of corneal sensation. The diagnosis of HSV keratitis is primarily clinical, although additional tests may be useful in providing confirmation, but never exclusion.[1-4] The Tzanck (Giemsa) smear of multinucleated epithelial cells is a quick test with high specificity but low sensitivity. HSV epithelial keratitis invariably involves active viral proliferation.[1-4] The classic epithelial dendrite is the most common presentation of epithelial disease (Figure 1). HSV stromal keratitis is associated with the highest and most severe morbidity of any ocular herpetic disease.[1-4] Although this condition frequently follows previous HSV epithelial keratitis, it can be the initial presentation of ocular herpetic disease. HSV disciform (endothelial) keratitis is a cell-mediated immune reaction to corneal endothelial tissue that presents with diffuse stromal edema.[1-4] In approximately half of cases, there is no prior history of HSV epithelial keratitis. HSV keratouveitis may occur as a separate entity or in association with herpetic epithelial, stromal, or endothelial disease.[1-4] It may be granulomatous or non-granulomatous and may, in some cases, be associated with live virus (Figure 6). Metaherpetic manifestations of HSV keratitis include neurotrophic keratopathy and microbial (i.e. Although HSV epithelial keratitis is self-limited in most cases, the rationale for aggressive antiviral therapy is to prevent corneal nerve damage and potential future immunologic disease.[1] Prior to the advent of antiviral therapy, simple epithelial debridement was the treatment of choice. The most common mistake in the management of HSV keratitis is premature termination of topical steroid therapy.
In our clinics, the taper for stromal keratitis and keratouveitis is only one-third complete when it has been reduced to prednisolone acetate 1.0% once daily. Our preferred steroid use and taper regimens are based upon whether or not the patient is a steroid-responder. The introduction of oral antiviral prophylaxis constituted a major advance in the management of chronic herpetic eye disease.
There are no uniformly accepted guidelines governing the use of antiviral prophylaxis in conjunction with topical corticosteroid use in situations where live viral manifestations are not present. Late surgical intervention is indicated for management of intractable corneal pain or visual impairment associated with herpetic disease. Stromal keratitis- Acute: mid-deep stromal infiltrate with intact epithelium and minimal necrosis. But by reducing the total number of virions that are involved, they limit the lesion's extent and severity. That's because at this point the rate of viral replication has not yet reached its peak and can still be stifled.
The FDA has given approval for 3 topical products for the treatment of cold sores:  1) Denavir® 1% (penciclovir).
The cream is applied to those external areas of the lips or face where the cold sore is developing, 5 times a day for 4 days.
Having said that, research seems to suggest that the combination medication Xerese® (antiviral plus steroid) is more effective than just-antiviral medications. It found that the total area of the cold sore lesions that formed were 50% smaller than when no treatment was used.
However, one of these studies also reported a reduction in the duration of pain, by 0.5 days. The conclusions drawn by all three of these studies seem to suggest that penciclovir cream is the more effective of the two.
However, short-course regimens of valacyclovir (Valtrex®) and famciclovir (Famvir®) now do have FDA approval for this use and have been shown to accelerate lesion healing and decrease pain.
However, further studies have concluded that both types of HSV can cause genital herpes and oral herpes symptoms. These fluids include genital fluids like vaginal discharge or semen, saliva or fluid coming from the sores that breakout due to the infection. When the virus is done replicating, it will start spreading into the skin cells and end up looking like clustered blisters. Therefore, it is necessary to start treating the condition as soon as symptoms become visible.
Upon noticing the first sign of the condition, for example the presence of herpes on lip it is necessary to talk to your physician immediately to determine what could have triggered the activation of the virus.
There was one controversial case when an infant died of herpes during a ritual circumcision. You can check out overviews, treatments, causes, symptoms and preventive measures for the condition to help you manage cold sore problems.

Herpes infections are caused by both herpes simplex virus type 1 (HSV-1) and herpes simplex virus type 2 (HSV-2). Slit lamp photo demonstrating classic epithelial dendrites in our patient after fluorescein staining.
Most cases (> 90%) are unilateral, but bilateral cases may occur, especially in atopic or immunocompromised patients. It represents areas of epithelial breakdown due to cell destruction by proliferating virus and is best demonstrated after fluorescein staining under cobalt blue lighting.
The vast majority of cases are an immune stromal keratitis (ISK), which involves the antibody-complement cascade against retained viral antigens in the stroma. Accordingly, acute-onset, unilateral corneal edema should be considered to be due to herpetic eye disease unless proven otherwise. A guiding principle is that prior to the onset of immune-mediated disease, control and elimination of epithelial manifestations is the highest priority. Our experience is that the optimal initial frequency is hourly for NSK, every two hours for ISK, and every three hours for disciform keratitis. In such cases, there is almost invariably a reappearance of corneal inflammation that is mislabeled as "recurrent" disease, when, in fact, it is actually a "pseudo-recurrence" that is merely a continuation of the same immunological reaction that has now become clinically apparent due to therapeutic withdrawal. Due to the very high benefit-to-risk ratio associated with oral antiviral therapy, it is our preference to use these medications in every instance in which topical corticosteroids are utilized.
For painful eyes without visual potential, a Gunderson flap will reduce chronic inflammation and eliminate pain. Full dose oral antiviral followed by prophylactic oral antiviral (for 1 year up to indefinitely). The virus will still reside in your body and your risk for continued outbreaks will remain the same. It was also found that the virus infects approximately 20% adult and adolescent population in the US. These viruses will then enter the body through the eyes, mouth or damaged skin that exposes the mucous membrane. However, in case symptoms are present, it would start showing up within one or two weeks after being infected by the virus through sexual intercourse.


However, you should know that there is no cure available for herpes simplex virus and there are no fever blister or cold sore medicine, but there are antiviral medications that can help treat its symptoms.
Your physician can also provide you information regarding the possible treatment options for the condition as well as the preventive steps that you should take to avoid its recurrence. New antiviral medications have expanded treatment options for the two most common cutaneous manifestations, orolabial and genital herpes. This image displays grouped blisters within an inflamed area of skin typical of herpes simplex. In chronic cases, demonstration of decreased sensation by Cochet-Bonnet aesthesiometry can be helpful in differentiating true recurrent dendritic keratitis from pseudo-dendritic keratitis, especially that related to recurrent epithelial erosions.
The presence of keratouveitis mandates a thorough funduscopic examination to exclude concomitant acute retinal necrosis.
However, once immune-mediated disease has been established, management of stromal or endothelial manifestations, with their potential for irreversible visual impairment, has higher priority than control of epithelial disease.
However, corneal toxicity related to the topical antivirals available in the United States led to a preference on the part of many specialists to rely exclusively on equally effective systemic therapy.
If concomitant epithelial disease is present, full systemic antiviral dosing is also required since steroid therapy exacerbates this condition. For eyes with post-herpetic scarring and good visual potential, the surgical procedure is based upon the corneal pathology. These can attack an individual together or separately and cause either genital or oral herpes.
About 10% to 25% of these people do not show any symptoms of the virus, but regardless of that, they can still transmit the virus to other individuals.
However, it will unpredictably activate later on and will then enter the shedding stage where the virus transmits from one individual to another. The infection due to HSV is recurrent by nature and it is necessary for the affected individual to be prepared for future outbreaks.
The most common clinical presentation of first-episode, primary herpes simplex virus infection in children (usually aged 6 mo to 5 y) is acute herpetic gingivostomatitis, as is shown in the image below. The transmission of herpes simplex virus (HSV) infection is dependent upon intimate, personal contact of a susceptible seronegative individual with someone excreting HSV. There was, however, patchy anterior stromal inflammation in the visual axis that did not resemble the characteristic post-dendritic "footprints" and was felt to represent early immune stromal keratitis (Figure 2).
On examination, the epithelium was intact but there was mild patchy anterior stromal haze in the same distribution in the visual axis as before. Bacterial and fungal cultures, along with confocal microscopy, can be used to rule out other etiologies of microbial keratitis.
Our preference is to use acyclovir 400 mg PO five times daily or valacyclovir 1000 mg PO three times daily. Phototherapeutic keratectomy may be utilized as a keratoplasty-sparing intervention for superficial corneal scarring.
Herpes simplex virus can be transmitted through direct physical contact or by contracting fluids, like genital discharge or saliva, from the infected individual. This is considered as the initial stage of the condition and infected individuals will not notice any symptoms of infection. The symptoms of the condition are more severe during its primary outbreak and gradually become milder with the succeeding outbreaks.
Just like genital herpes, oral herpes may also recur at any given time and the first outbreak is the most troublesome.
It is also important to follow precautionary measures to prevent the virus from being transmitted to other individuals. It results in painful herpes simplex virus lesions, frequently with numerous cutaneous vesicles. Virus must come in contact with mucosal surfaces or abraded skin for infection to be initiated. Treatment was initiated with topical prednisolone acetate 1.0% QID, while maintaining antiviral and prophylactic antibiotic coverage.
There are unsubstantiated concerns that this procedure may be associated with activation of immunological stromal keratitis; in any case, perioperative use of full antiviral therapy followed by a prolonged prophylactic course obviates this issue.

There was no peripheral stromal vascularization, perineuritis, endothelial or anterior chamber inflammation.
Although most practitioners prefer a short course of therapy, we treat our patients for a total of 14 to 21 days to ensure complete eradication of replicating organisms. For deeper stromal scarring, penetrating or deep anterior lamellar keratoplasty are the procedures of choice. Herpes labialis infection occurs when the herpes simplex virus comes into contact with oral mucosal tissue or abraded skin of the mouth. Painful diseases caused by herpes simplex virus (HSV) or varicella zoster virus (VZV, also causes chickenpox). After successful treatment, therapy can be discontinued without tapering, unless long-term prophylaxis is used (see below; antiviral prophylaxis).
The prognosis for graft survival has improved dramatically over the last quarter century since the introduction of oral antiviral prophylaxis. Infection by the type 1 strain of herpes simplex virus (HSV-1) is most common; however, cases of oral infection by the type 2 strain are increasing.
This can be attributed to reduced recurrence of herpetic epithelial keratitis, a condition that is frequently associated with acute endothelial rejection episodes.
Neither ISK nor NIK is self-limited and failure to provide appropriate pharmaceutical intervention will result in progressive corneal scarring and visual impairment. In the unusual situation of corneal endothelial decompensation due to neglected or recalcitrant endothelial keratitis, endothelial keratoplasty can be performed if stromal disease has not been present.
All that body bashing and face-to-face smearing in contact sports does wonders for spreading skin or cutaneous infections.
Two types are distinguished: type 1 (HSV-1) is generally associated with most oral (cold sores) and central nervous system infections, and type 2 (HSV-2) with genital herpes.
Zoster is a localized, generally painful cutaneous eruption that occurs most frequently among older adults and immunocompromised persons.
Shortly thereafter, this workgroup reformed as the ACIP shingles workgroup and, during subsequent months, held 19 conference calls to review and discuss scientific evidence related to herpes zoster and zoster vaccine, including the epidemiology and natural history of zoster and its sequelae, and the safety, immunogenicity, efficacy, financing, storage, and handling of the zoster vaccine.
