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.

Along with its needed effects, a medicine may cause some unwanted effects. Although not all of these side effects may occur, if they do occur they may need medical attention.
Check with your doctor immediately if any of the following side effects occur:
Less common
Burning, stinging, or pain on the application site
Rare
Blistering, crusting, irritation, itching, or reddening of the skin
cracked, dry, scaly skin

redness of the skin
severe abdominal or stomach cramps and pain
tightness in the chest
unusual tiredness or weakness
watery and severe diarrhea, which may also be bloody
Some side effects may occur that usually do not need medical attention. These side effects may go away during treatment as your body adjusts to the medicine. Also, your health care professional may be able to tell you about ways to prevent or reduce some of these side effects. Check with your health care professional if any of the following side effects continue or are bothersome or if you have any questions about them:
Other side effects not listed may also occur in some patients. If you notice any other effects, check with your healthcare professional.
Call your doctor for medical advice about side effects. You may report side effects to the FDA at 1-800-FDA-1088.

Make sure to use mupirocin for as long as your healthcare professional (HCP) instructed you to. Don't stop using the medication earlier than prescribed even if your skin starts looking better. Your infection might not be entirely gone. It might come back and be harder to treat.
Wash your hands before and after you use mupirocin. Use a clean cotton swab or gauze pad to apply the medication onto the affected area of your skin. This helps prevent the infection from spreading or getting worse.
Use mupirocin only on small areas of the skin. Avoid getting the medication in your eyes, nose, mouth, or vagina (mucosal surfaces). Otherwise, it might cause irritation. Rinse your eyes well with water if you accidentally get mupirocin in your eyes.
After you apply mupirocin, you can use a sterile (clean) gauze pad to cover and protect the area, unless your HCP instructed you otherwise.
You might feel some slight irritation where you applied mupirocin on your skin. Let your HCP know if any skin irritation becomes bothersome or if it doesn't go away.
Avoid using other lotions, creams, ointments, or other topical products at the same time as mupirocin on the same area of skin. We're not sure what effects there are when mupirocin and other topical products are on the affected area at the same time. It might be a good idea to wait until you've finished your treatment course with mupirocin to use any other topical products on the treated area of skin.
Don't use mupirocin ointment on skin that's at or near any tubing that's inserted into a vein. It's possible that the medication can make fungal infections that are hard to treat pop up there.
Let your HCP know if your skin infection doesn't improve within 3 to 5 days of using mupirocin or if your skin infection gets worse. Your HCP can check whether you need other treatment.
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.
Risk factors: Long-term use of mupirocin
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.

Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. Tell your healthcare professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine.
