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.
Mupirocin is an antibiotic. The medication blocks bacteria from making certain proteins they need to survive. This kills bacteria to help treat skin infections.

Mupirocin can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
In some rare cases, mupirocin can cause an allergic reaction, which can be severe or life-threatening. Stop using the medication and get medical help right away if you have rash, hives, swelling, trouble breathing, or other symptoms of anaphylaxis.
Though rare, mupirocin carries a risk for diarrhea that's caused by a bacterial infection called Clostridioides difficile (C. diff). Like with all antibiotics, mupirocin can change how much normal bacteria is in your gut, allow C. diff to overgrow there, and cause an infection once the medication gets absorbed into the body. But keep in mind that mupirocin is used on the skin, so very little medication typically gets absorbed.
The risk that mupirocin gets absorbed into the body and causes C. diff infection is higher if the medication is applied onto damaged skin. This infection can be very contagious, cause diarrhea, and lead to life-threatening dehydration. Get medical help right away if you have symptoms like rapid heart rate, fever, foul-smelling diarrhea, or frequent bowel movements.
Using mupirocin for long periods of time can give rise to the growth of treatment-resistant bacteria or fungi. This means that the medication won't work well to kill the bacteria or fungi, and new infections can be very difficult to treat. To prevent this from happening, be sure to use mupirocin as directed and not for a longer period of time than your HCP prescribed.
Mupirocin ointment contains an inactive ingredient that can be toxic when a large amount is absorbed into the body through damaged skin. The kidneys normally help get rid of this inactive ingredient from the body.
The risk for possible harmful effects from the inactive ingredient is higher if you have moderate-to-severe kidney problems. When your kidneys don't work properly, your body can't get rid of the inactive ingredient well. This raises the risk for the inactive ingredient to build up in the body and cause harm. Tell your HCP before you use mupirocin ointment if you have kidney problems to make sure it's safe for you.
