How It Works: Mupirocin is an antibiotic. Antibiotics can improve acne symptoms by limiting the growth of bacteria that contribute to Acne Vulgaris.
When is this medication used? Mupirocin is is used for the treatment of all types of acne, from mild to severe acne (Acne Types: 1-4). In cases of moderate to severe acne (Acne Types: 3-4), Mupirocin is often combined with additional treatments (eg, oral antibiotic, oral retinoids and/or light and laser therapy).
Frequency of Mupirocin Resistant P. acnes Bacteria: Common. (What does this mean?)
Official Name: Mupirocin
Popular Brand Names: Bactroban, Centany, Dermoban, Micoban.

Mupirocin and Acne
For some acne patients mupirocin is a moderately effective anti-acne medication that has few side effects. Some patients report rapid and significant improvement in their symptoms after beginning treatment with topical mupirocin.
The most common problem associated with the use of mupirocin in acne treatment is that many patients report the medication becomes less effective over time. This is most likely due to the target bacteria (Propionibacterium acnes) becoming resistant to mupirocin.
The development of antibiotic resistance during treatment appears to be a major limitation of mupirocin treatment (it is also a major problem with the quinolone family of antibiotics). The problems with rapidly acquired resistance to mupirocin and quinolones (eg. ciprofloxacin) are likely related to the manner in which the bacteria become resistant. It appears that small genetic mutations can yield high levels of resistance to these particular antibiotics. In contrast, many other antibiotics (eg. penicillins) may require the acquisition of an entire gene (which is much less likely to happen than a small genetic mutation).
Because of mupirocin tends to become less effective over the course of treatment, it is poorly suited for the long-term control of acne symptoms. However, mupirocin can prescribed in conjunction with other medications, including oral and topical medications, oral and topical retinoids and light and laser therapies. The short-term use of mupirocin at the beginning of a multi-drug treatment may accelerate the resolution of acne symptoms.
Patient Reviews of Mupirocin
Topical mupirocin appears to be moderately effective against mild to moderate acne (Acne Types: 1-2). However, mupirocin tends to be innefective for the treatment of moderate to severe acne (Acne Types: 3-4). Some types of bacteria can rapidly acquire resistance to mupirocin. This can cause mupirocin to become less effective over time.
Cost and Availability of Mupirocin
When possible, mupirocin should be obtained through consultation of a physician. Many doctors and dermatologists are familiar with this medication, although many are not. Mupirocin is moderately expensive and is widely available in brand name and generic formulations.
Mupirocin Adverse Effects
The most common side effect of topical mupirocin treatment is mild skin irritation. In rare cases, patients may experience more serious skin irritations. Topically applied mupirocin is poorly absorbed into the blood stream and systemic reactions are rare.

Mupirocin is an antibiotic that is primarily used in the treatment of skin infections. It is a mixture of molecules called Pseudomonic acids. These molecules kill susceptible bacteria by preventing the bacteria from utilizing an essential amino acid, isoleucine. Without isoleucine, bacteria are unable to synthesize new proteins and replicate.
Mupirocin is commonly used to treat Impetigo, and is also a useful addition to combination treatments for MRSA (methicillin resistant Staphylococcus aureus. Because mupirocin has a different mechanism of action than most other antibiotics, it is often used in synergistic combinations with other oral and topical antibiotics. These combination treatments are often more effective than the use of mupirocin alone.
