Key takeaways
Mupirocin (Bactroban, Centany) and acyclovir (Zovirax, Sitavig) are both prescription medications used to treat infections, but they belong to different classes and treat different types of infections. Mupirocin is a topical antibiotic used to treat bacterial skin infections like impetigo, while acyclovir is an antiviral medication used to treat viral infections such as shingles, chickenpox, and genital herpes. Mupirocin is applied as a cream or ointment to the skin three times a day for up to 10 days, whereas acyclovir can be taken orally or applied topically, with dosing frequency varying based on the form and condition being treated. Mupirocin is generally well-tolerated with few side effects, but may cause headache and burning at the application site. Oral acyclovir can cause nausea, vomiting, and diarrhea, while topical acyclovir can cause burning at the application site. Additionally, acyclovir requires more frequent dosing, often 4 to 5 times a day, and can increase the risk of kidney problems, particularly in older adults or those who already have kidney problems.

Summary of Mupirocin vs. Acyclovir
Summary for Antibiotic
Prescription only
Mupirocin is a topical antibiotic that's used to treat small areas of bacterial skin infections such as impetigo or a "Staph" infection on the skin. It comes as a cream and an ointment that are applied onto the skin a few times a day for 10 days. This medication can be used on adults or children (over the age of 2 months for the ointment, and over the age of 3 months for the cream). Although mupirocin has very few side effects, some people can experience headache, nausea, or burning at the application site.
Summary for Antiviral
Prescription only
Acyclovir is an antiviral oral medication used to treat infections caused by the herpes virus, including shingles, chickenpox, and genital herpes. It comes as a tablet, capsule, and liquid suspension. Depending on your condition, you might need to take it by mouth 2 to 5 times a day. Acyclovir works best when you start it as soon as symptoms begin. Common side effects include nausea, vomiting, and diarrhea.
