Mupirocin ointment is a topical antibiotic medication used for the treatment of bacterial skin infections. This antibiotic works by killing the bacteria that cause infections on the skin. It is a common treatment for conditions like impetigo, a skin infection that typically affects children, and folliculitis, an infection of hair follicles that often appears as small, red bumps on the skin.
Understanding Mupirocin Ointment and How It Works
Mupirocin ointment works by inhibiting the growth of bacteria at the site of infection. It is an antibacterial agent that is effective against a wide range of gram-positive bacteria, including those that are resistant to other antibiotics. The active ingredient in mupirocin ointment is called mupirocin, which is a combination of two active molecules – pseudomonic acid A and pseudomonic acid B. These molecules work together to prevent the bacteria from synthesizing protein that is essential to their survival. This, in turn, leads to the death of bacteria, stopping the spread of the infection and promoting healing of the affected area of skin.
Mupirocin ointment is commonly used to treat skin infections, such as impetigo, folliculitis, and infected eczema. It is also used to prevent infections in wounds, cuts, and burns. The ointment is applied directly to the affected area of skin, usually two to three times a day, until the infection has cleared up.
It is important to note that mupirocin ointment should only be used as directed by a healthcare professional. Overuse or misuse of the ointment can lead to the development of antibiotic-resistant bacteria, which can be difficult to treat. If you experience any side effects or your symptoms do not improve after a few days of using the ointment, you should consult your doctor.
The History of Mupirocin Ointment
Mupirocin was first discovered in the late 1970s through a natural product screening program that was searching for antibiotic drugs derived from soil bacteria. It was identified as an antibacterial agent in cultures of Pseudomonas fluorescens, a non-pathogenic soil bacterium. The compound went through extensive research and development before it was first approved by the US Food and Drug Administration (FDA) in 1985.
Mupirocin ointment is commonly used to treat skin infections caused by bacteria, such as impetigo, folliculitis, and infected wounds. It works by inhibiting bacterial protein synthesis, which ultimately leads to the death of the bacteria. Mupirocin ointment is considered a safe and effective treatment option for these types of infections, and is available in both prescription and over-the-counter formulations.
How to Use Mupirocin Ointment Effectively
Mupirocin ointment is usually applied to the affected area of skin two to three times per day. Before using the ointment, it is important to clean the area thoroughly and dry it completely. The ointment should be applied in a thin layer over the affected area. It is important to avoid using more than the prescribed amount of ointment, as this can lead to side effects.
It is also important to note that mupirocin ointment should only be used for the duration prescribed by your healthcare provider. If symptoms persist or worsen, it is important to consult with your healthcare provider. Additionally, mupirocin ointment should not be used on open wounds or burns, as it can cause further irritation and delay healing.
While using mupirocin ointment, it is important to practice good hygiene to prevent the spread of infection. This includes washing your hands frequently, avoiding sharing personal items such as towels or razors, and keeping the affected area clean and dry. If you have any concerns or questions about using mupirocin ointment, be sure to discuss them with your healthcare provider.
Possible Side Effects of Using Mupirocin Ointment
Side effects associated with mupirocin ointment are generally mild and include skin irritation, redness, or itching at the site of application. In rare cases, more severe side effects like swelling, hives or an allergic reaction can occur. It is important to consult a physician if you experience any of these symptoms.
It is also important to note that prolonged use of mupirocin ointment can lead to the development of antibiotic-resistant bacteria. This can make it more difficult to treat infections in the future. Therefore, it is recommended to only use mupirocin ointment as directed by a healthcare professional and to not use it for longer than prescribed.
Additionally, mupirocin ointment should not be used on large areas of the body or on open wounds without the guidance of a healthcare professional. This is because it can be absorbed into the bloodstream and potentially cause harmful side effects. It is important to follow the instructions provided by your healthcare provider and to report any unusual symptoms or side effects that you may experience while using this medication.
Precautions to Take When Using Mupirocin Ointment
Mupirocin ointment should not be applied to open wounds, broken skin, or mucous membranes. Avoid contact with the eyes and nose. If you accidentally get the ointment in your eyes, rinse with water immediately and contact a doctor if necessary. It is important to inform your physician of any other medications or supplements you are taking, as they may interact with mupirocin ointment.
Additionally, it is important to use mupirocin ointment only as directed by your healthcare provider. Do not use more or less of the medication than prescribed, and do not use it for longer than recommended. If your symptoms do not improve or worsen after a few days of using the ointment, contact your doctor.
It is also important to note that mupirocin ointment is not effective against viral or fungal infections. If you have a skin infection that is not caused by bacteria, mupirocin ointment will not be effective in treating it. Your doctor may need to prescribe a different medication to treat the infection.
Alternatives to Mupirocin Ointment for Skin Infections
There are other topical antibiotics that can be used to treat skin infections, including clindamycin, erythromycin, and neomycin. These antibiotics work in a similar way to mupirocin ointment, and may be prescribed by a physician in cases where mupirocin ointment is not effective or suitable for the individual’s case.
It is important to note that the overuse of topical antibiotics can lead to antibiotic resistance, making it more difficult to treat infections in the future. In some cases, non-antibiotic treatments such as antiseptics or wound dressings may be recommended instead. It is always best to consult with a healthcare professional to determine the most appropriate treatment for a skin infection.
When Should You Use Mupirocin Ointment?
Mupirocin ointment is prescribed for the treatment of bacterial skin infections caused by susceptible organisms. Common indications for use include impetigo, folliculitis, and other bacterial skin infections. The use of this ointment should be determined by a qualified physician, taking into account the individual’s specific condition and medical history.
It is important to note that overuse or misuse of mupirocin ointment can lead to the development of antibiotic-resistant bacteria. Therefore, it is crucial to follow the prescribed dosage and duration of treatment. Additionally, individuals with a history of allergies to any of the ingredients in the ointment should inform their physician before using it. If any adverse reactions occur, such as severe itching, rash, or difficulty breathing, seek medical attention immediately.
Comparing Mupirocin Ointment with Other Topical Antibiotics

The Science Behind How Mupirocin Ointment Fights Infections
The active ingredient in mupirocin ointment, pseudomonic acid A, works by preventing the bacteria from synthesizing protein that is essential to their survival. Specifically, the molecule inhibits the transfer of amino acids from transfer RNA (tRNA) to ribosomes, where the amino acids are used to build proteins. Without these essential building blocks, the bacteria cannot grow or reproduce, leading to their eventual death.
Additionally, mupirocin ointment has been found to have a unique ability to penetrate the skin and reach the site of infection. This is due to its small molecular size and lipophilic nature, which allows it to easily cross the skin barrier and enter the underlying tissues. Once it reaches the site of infection, it can effectively target and eliminate the bacteria causing the infection.
It is important to note that while mupirocin ointment is highly effective against many types of bacteria, it is not effective against viruses or fungi. It is also important to use the ointment as directed and complete the full course of treatment, even if symptoms improve, to ensure that all bacteria are eliminated and to prevent the development of antibiotic resistance.
Can You Get Mupirocin Ointment Over the Counter?
Mupirocin ointment is usually available only by prescription from a qualified physician. In some cases, pharmacies may allow the purchase of topical antibiotics without a prescription, but this may not be the case for all regions.
How Long Does It Take for Mupirocin Ointment to Work?
The effectiveness of mupirocin ointment varies depending on the individual’s condition and the severity of the infection. In general, the ointment can begin to work within a few days, but longer courses may be required for serious skin infections to resolve.
Tips for Storing and Handling Mupirocin Ointment Safely
Mupirocin ointment should be stored in a cool, dry place away from direct sunlight. It is important to keep the ointment out of reach of children and pets. Do not use the ointment after its expiration date, as this may cause adverse reactions to the skin. If you are unsure about proper storage or have any questions about the ointment, consult with a qualified physician or pharmacist.
Overall, mupirocin ointment is a safe and effective treatment option for bacterial skin infections. With proper use and precautions, individuals can experience relief from their symptoms and promote healing of the affected area.
