What Cream Can You Put on Genital Herpes?

Topical acyclovir cream exists as a prescription option for genital herpes, but it is not the treatment most doctors recommend. Current clinical guidelines from the CDC discourage the use of topical antiviral formulations for genital herpes, noting they provide “minimal clinical benefit” compared to oral antiviral pills. That said, several creams and topical agents have been studied for herpes sores, and some people use them alongside or instead of oral medication for various reasons. Understanding what works, what barely works, and what might actually irritate things further is worth sorting through.

Why Oral Antivirals Are the Standard, Not Creams

If you visit a doctor for a genital herpes outbreak, you will almost certainly be prescribed an oral antiviral like acyclovir, valacyclovir, or famciclovir in pill form. The reason is straightforward: oral antivirals reach the virus systemically through your bloodstream, which means they can fight the infection at nerve roots where the virus hides, prevent new lesions from forming, and reduce constitutional symptoms like fever and body aches. Topical creams, by contrast, only work on the skin surface where you apply them. They cannot stop new sores from popping up in areas you did not cover, and they cannot address the systemic aspects of an outbreak.

An evidence-based review in the Archives of Internal Medicine put it plainly: unlike topical acyclovir, the oral form can prevent new lesion formation, modify systemic symptoms, and does not cause local irritation on application.¹ That review noted that the CDC’s guidelines specifically discourage topical formulations for genital herpes. So if your doctor gives you pills rather than a cream, that is considered the best practice, not a missed opportunity.

Prescription Topical Acyclovir and Penciclovir

Topical acyclovir cream does have real antiviral activity against herpes simplex virus, and clinical trials have measured its effects. In first episodes of genital herpes, patients using topical acyclovir experienced a median pain duration of about 4 days compared to 8 days with placebo, and lesions healed in roughly 8 days versus 14 days. Viral shedding, the period when the virus can be transmitted, dropped from a median of 11 days to 4 days. For recurrent episodes the benefits were smaller but still present: symptoms lasted about 3 days with acyclovir versus 6 days with placebo, and new lesion formation was much less likely.²

Penciclovir cream, a related antiviral better known for cold sore treatment under the brand name Denavir, has also been tested on genital herpes. A randomized double-blind trial comparing penciclovir 1% cream to acyclovir 3% cream found no significant differences in clinical cure rate, time to healing, or resolution of symptoms between the two. The only notable difference was that penciclovir led to slightly faster crusting in first-episode patients.³ In practice, neither topical antiviral cream is widely prescribed for genital herpes anymore because oral antivirals outperform them.

One practical issue with topical antivirals worth knowing: they need to be applied multiple times a day, typically five to six times, which is both inconvenient and easy to forget. The cream can also cause local skin irritation in some people. Oral medication, taken just two or three times daily depending on the drug, is simpler and reaches the virus more effectively. If you already have topical acyclovir cream at home, using it on a sore is not harmful, but do not expect it to work as well as the oral version.

Zinc Sulfate as a Topical Treatment

Zinc has well-documented antiviral and wound-healing properties, and researchers have investigated whether applying zinc sulfate solution directly to genital herpes sores can help. A study published in the Indian Journal of Dermatology tested three different concentrations of topical zinc sulfate and found that the 4% concentration was the most effective, not only for treating active outbreaks but also for prolonging the time before the next recurrence. The researchers reported no side effects at that concentration.⁴

Zinc sulfate solution is not a standard pharmacy product you can pick up off the shelf in a ready-to-apply genital herpes formulation. You would typically need a compounding pharmacy or a dermatologist’s guidance to get the right concentration. Over-the-counter zinc oxide creams, the kind used for diaper rash, are a different product with a different mechanism and have not been studied the same way for genital herpes. If zinc sulfate interests you, bring the research to your doctor rather than improvising with whatever zinc product you find at the drugstore.

Propolis Ointments

Propolis, a resinous substance that bees produce to seal their hives, has attracted serious research attention for herpes treatment. It contains flavonoids and other compounds with antiviral and anti-inflammatory properties, and multiple clinical trials have now tested propolis ointments head-to-head against acyclovir cream for genital herpes.

In one multicenter trial, 90 patients with genital herpes were randomly assigned to propolis ointment, acyclovir cream, or placebo. By day 10, 24 out of 30 patients in the propolis group had healed, compared to 14 out of 30 in the acyclovir group and 12 out of 30 in the placebo group.⁵ That is a striking result, though the study was relatively small.

Two separate meta-analyses have since pooled data from multiple trials and reached broadly similar conclusions. One found that propolis and honey treatments were associated with lesion resolution roughly two days faster than acyclovir, with higher healing rates by day 7. Patients also reported shorter pain duration and lower pain intensity, and more were symptom-free by day 3. Adverse event rates were comparable between the natural products and acyclovir.⁶ The other meta-analysis similarly concluded that propolis had superior healing properties compared to acyclovir.⁷

A few caveats are important here. These studies compared propolis to topical acyclovir, not to oral antivirals, which are the actual standard of care. Beating a topical cream that the CDC already considers minimally effective is a lower bar than beating oral valacyclovir. Propolis products also vary enormously in composition depending on the bee species, geographic region, and manufacturing process, so one brand’s ointment may not perform like another’s. Still, propolis ointment is available without a prescription, is generally well-tolerated, and the clinical data behind it is more robust than for most alternative topicals.

Lemon Balm (Melissa Officinalis)

Lemon balm extract has a long folk-medicine history for treating cold sores, and laboratory studies confirm it has real antiviral activity against herpes simplex virus. Multiple in vitro experiments have shown that lemon balm extracts can inhibit both HSV-1 and HSV-2, working through several mechanisms including blocking viral attachment to cells and interfering with viral replication after the virus has already entered a cell.⁸ One study specifically targeting HSV-2 found that lemon balm extract reduced viral damage to cells by up to 60% at non-toxic concentrations.⁹

A literature review of lemon balm’s antiviral potential noted that the plant can fight several viruses including HSV through mechanisms like inhibiting the virus from binding to host cells and blocking viral replication.¹⁰ Lemon balm creams and lip balms are commercially available, and the cream has been studied in small clinical trials for oral herpes with positive results.

The limitation is that most of the strong evidence is from lab experiments rather than large clinical trials in people with genital herpes specifically. Killing a virus in a dish is not the same as treating an outbreak on skin, because penetration, concentration, and the body’s own immune response all play a role. Lemon balm cream is unlikely to cause harm and may provide some symptom relief, but it has not been validated as a genital herpes treatment in the same way propolis has been through head-to-head clinical trials.

Soothing Creams That Are Not Antivirals

Sometimes the question is less about fighting the virus and more about managing the pain, itching, and discomfort of an active outbreak. Several non-antiviral products can help with that:

Petroleum jelly: A thin layer of plain petroleum jelly over sores can protect them from friction against clothing and prevent the skin from cracking painfully as it heals. It does not have antiviral properties, but it reduces mechanical irritation significantly.
Lidocaine gel or cream: Topical lidocaine (available over the counter in lower concentrations or by prescription at higher ones) numbs the skin surface. It can make urination less painful when sores are near the urethra, which is one of the more miserable aspects of a genital herpes outbreak.
Plain zinc oxide cream: While not the same as the zinc sulfate solution studied in clinical trials, zinc oxide paste can provide a protective barrier and has mild anti-inflammatory properties. It is gentle and widely available.

These products are not treatments for herpes. They do not shorten outbreaks or reduce viral shedding. But during an active episode, comfort matters, and a barrier cream or numbing agent can make the difference between a tolerable few days and a miserable week.

What to Avoid Putting on Genital Herpes Sores

The genital area is sensitive, and broken skin from herpes lesions is even more so. Some products that seem intuitively helpful can actually make things worse. Alcohol-based antiseptics like rubbing alcohol or hydrogen peroxide will sting intensely and can damage healing tissue without offering any meaningful antiviral benefit. Tea tree oil, while it has some antiviral properties in lab settings, is a potent skin irritant at the concentrations found in many commercial products and can cause contact dermatitis on already compromised genital skin.

Hydrocortisone cream is another common reach-for that deserves caution. While it reduces inflammation and itching, corticosteroids suppress the local immune response, which is exactly what you do not want when your body is trying to fight off a viral outbreak. Short-term use on intact skin for itching is unlikely to cause serious problems, but applying it directly to open herpes sores could theoretically slow healing. Antibiotic ointments like Neosporin are unnecessary unless a secondary bacterial infection develops, and the fragrance and preservatives in some formulations can irritate inflamed tissue.

A good rule of thumb: if it burns when you apply it, stop. Herpes sores heal best in a clean, protected, moist environment. Gentle washing with plain water, patting dry, and applying a simple barrier like petroleum jelly is less dramatic than reaching for medicated creams but is often more effective at reducing discomfort.

Genital Herpes Treatment During Pregnancy

Pregnant women with genital herpes face a specific concern because the virus can be transmitted to the baby during delivery, particularly during a first outbreak near the time of birth. The question of which medications are safe comes up frequently. Studies have shown that oral acyclovir and valacyclovir are not associated with an increase in birth defects, and both are considered appropriate for use during pregnancy. Data on famciclovir is more limited, so it is not typically a first-line choice for pregnant patients.¹¹

Most pregnant women with recurrent genital herpes are offered suppressive oral antiviral therapy starting around 36 weeks of gestation to reduce the chance of an active outbreak at the time of delivery. In terms of topical treatments, the same general principle applies: oral antivirals are preferred because they are more effective. A topical cream alone would not provide the systemic suppression needed to protect the baby during delivery. If you are pregnant and managing genital herpes, this is a conversation for your obstetrician, not a decision to make in the pharmacy aisle.

Emerging Topical Research

Researchers are exploring next-generation topical products that go beyond traditional antiviral creams. One example is PC-1005, a gel being developed as a multipurpose prevention technology designed to protect against both HIV and HSV-2. In a phase I trial, rectal application of PC-1005 resulted in a 66 to 87% decrease in HSV-2 viral activity in rectal fluid at early time points after application, with the antiviral effect being significantly different from pre-dose levels.¹² This is early-stage research, and the product is not available to consumers, but it represents a different approach: rather than treating outbreaks after they start, the goal is a topical product that could be applied preventively to reduce transmission risk.

Other lines of investigation include microbicide gels that combine antiviral compounds with agents that modify the local immune environment, and nanoparticle-based delivery systems designed to get antiviral drugs deeper into skin tissue than traditional creams can reach. None of these are close to pharmacy shelves yet, but the interest in better topical options reflects a real gap in current treatment. Oral antivirals work well for most people, but a highly effective topical could be valuable for those who cannot tolerate oral medication, who want on-demand protection during intimate contact, or who prefer not to take daily pills.

How to Think About Your Options

If you are in the middle of a genital herpes outbreak and wondering what to put on it, the clearest path is to see a doctor and get oral antiviral medication. That remains the single most effective intervention. For symptom relief while you wait or alongside your pills, a simple barrier like petroleum jelly or a numbing agent like lidocaine gel will do more practical good than most medicated creams.

If oral antivirals are not an option for you, or if you prefer to add a topical treatment alongside them, propolis ointment has the strongest clinical evidence among non-prescription topicals, with multiple trials and two meta-analyses showing faster healing compared to topical acyclovir. Zinc sulfate solution at 4% has shown promise in a smaller body of research. Lemon balm cream has laboratory support but limited human trial data for genital herpes specifically. All of these are reasonable to discuss with a healthcare provider, and none are likely to cause harm when applied to intact or mildly broken skin. The one thing not to do is assume that any cream, no matter how good, is a substitute for antiviral medication during a severe first episode or when managing outbreaks during pregnancy. Topicals occupy a supporting role in genital herpes management. The heavy lifting, for now, still belongs to pills.
