Can Mupirocin Be an Effective Treatment for Herpes?

Herpes, a common viral infection, often prompts patients like you to seek effective treatments. Among various medications, you might wonder about the role of mupirocin in treating herpes. Before we talk about whether mupirocin is an effective treatment for herpes, it’s important to understand what herpes is and what mupirocin is typically used for.

What is Herpes?

Herpes is a common viral infection caused by the herpes simplex virus (HSV). There are two types: HSV-1, usually responsible for oral herpes (cold sores), and HSV-2, typically causing genital herpes. Herpes causes blisters or sores in the affected areas and is a lifelong condition with periods of dormancy and outbreaks.

What is Mupirocin?

Mupirocin is an antibiotic ointment commonly used to treat bacterial skin infections like impetigo. It works by stopping the growth of certain bacteria.

Mupirocin’s Effectiveness Against Herpes

Antibiotics vs. Antivirals

It’s crucial to note that mupirocin is an antibiotic, and antibiotics are effective against bacteria, not viruses. Since herpes is a viral infection, antibiotics like mupirocin don’t target the herpes virus.

Proper Treatment for Herpes

Antiviral medications are used to treat herpes. These include drugs like acyclovir, valacyclovir, and famciclovir. These medications can help reduce the severity and frequency of outbreaks and, in some cases, prevent them.

Mupirocin’s Role

Mupirocin may be prescribed if there’s a secondary bacterial infection in the herpes sores. Sometimes, open sores can become infected with bacteria, and in such cases, an antibiotic ointment, not herpes itself, might be used to treat that bacterial infection.


Mupirocin is not an effective treatment for herpes because it is an antibiotic, and herpes is a viral infection. For herpes, antiviral medications are the appropriate treatment. However, if a secondary bacterial infection develops in the sores, a doctor might prescribe an antibiotic like mupirocin to address that specific issue. Always consult with a healthcare professional for the right diagnosis and treatment.

Frequently Asked Questions

Can I use over-the-counter ointments for herpes?

Over-the-counter ointments might provide symptom relief, but they won’t cure herpes. Antiviral medications are typically needed for effective treatment.

How can I manage herpes symptoms at home?

While waiting for a healthcare appointment, you can manage pain with warm baths, keeping the affected area clean and dry, and wearing loose-fitting clothing.
