What is Mupirocin?
Mupirocin is a topical antibiotic that helps treat paronychia, a condition characterized by inflammation around the nail. Common symptoms include redness, swelling, and pain. In serious cases, your nails may become discolored or misshapen. While antibiotics aren’t always necessary, your doctor might recommend Mupirocin if your condition is severe or persists.[1]
Although it can be an effective treatment for paronychia, Mupirocin ointment is used off-label for this condition. Off-label simply means that Mupirocin hasn’t been officially approved for paronychia yet, and this use is not listed in the medication guide. But Mupirocin is relatively commonly prescribed for paronychia if a bacterial infection is suspected.[3]
How does Mupirocin work?
Mupirocin works by inhibiting bacterial protein synthesis. Without proteins, bacteria can’t grow and survive, which eventually leads to their death. This helps clear the infection.[2]
Will I get side effects with Mupirocin?
There’s a chance of getting side effects with Mupirocin, but not everyone will get them. As it’s applied topically, Mupirocin doesn’t cause many of the side effects typically associated with oral antibiotics. The most common one is a burning sensation where you apply it. Others include redness or itching, but these are uncommon.
Is Mupirocin available over the counter?
No. You can only get Mupirocin with a prescription, as it’s an antibiotic. Your doctor will need to check that you have a bacterial infection before prescribing it to make sure it’s right for you.
What doses of Mupirocin are there?
Mupirocin comes in one dose: 2% w/v. You’ll usually apply it twice or thrice a day around your nails.
