From the Guidelines
Combining mupirocin ointment with another agent is not recommended without proper medical advice, as it may lead to harmful drug interactions, reduced effectiveness, or adverse reactions. When considering the combination of mupirocin ointment with another agent, it is essential to consult with a healthcare provider who can evaluate the specific condition, review the actual medications being considered, and provide personalized advice based on the patient's medical history and needs 1.
Key Considerations
- The healthcare provider can determine if the medications are compatible and appropriate for the condition being treated.
- They can also advise on how the medications should be applied, including which should be applied first and how much time should elapse between applications.
- The potential benefits and risks of combining mupirocin ointment with another agent must be carefully weighed, taking into account the patient's individual circumstances and the severity of their condition.
Evidence-Based Guidance
- According to the Infectious Diseases Society of America, mupirocin ointment is effective for the treatment of impetigo and other skin infections caused by Staphylococcus aureus and Streptococcus pyogenes 2.
- However, the combination of mupirocin ointment with other agents, such as chlorhexidine and diluted bleach baths, may be considered for decolonization in patients with recurrent MRSA infections 1.
- It is crucial to note that the efficacy of such combinations has not been extensively studied, and more research is needed to determine their safety and effectiveness.
Patient-Specific Factors
- The decision to combine mupirocin ointment with another agent should be made on a case-by-case basis, taking into account the patient's medical history, the severity of their condition, and their individual response to treatment.
- Patients should be closely monitored for signs of adverse reactions or reduced effectiveness when combining medications, and adjustments should be made as needed to ensure optimal treatment outcomes.
From the FDA Drug Label
The effect of the concurrent application of mupirocin ointment and other drug products has not been studied. The effects of combining mupirocin ointment with another agent are unknown because there are no studies that have investigated this interaction 3.
From the Research
Effects of Combining Mupirocin Ointment with Another Agent
There are no direct studies on the effects of combining mupirocin ointment with another agent. However, the available studies provide information on the efficacy of mupirocin ointment compared to other topical antibiotics.
Comparison with Other Topical Antibiotics
- Mupirocin ointment has been compared to sodium fusidate ointment in several studies 4, 5.
- Both preparations were found to be effective in treating superficial skin sepsis, with no significant difference in clinical response between the two 4.
- Mupirocin was found to be more effective in treating acute primary skin infections and impetigo compared to sodium fusidate 5.
- Mupirocin was also found to be more effective in eliminating Staphylococcus aureus and/or beta-haemolytic streptococci compared to sodium fusidate 5.
Efficacy of Mupirocin Ointment
- Mupirocin ointment has been shown to be effective in treating primary and secondary skin infections, with a high rate of clinical cure or improvement 6, 7, 8.
- The ointment has been found to be effective against a wide range of Gram-positive bacteria, including Staphylococcus aureus and streptococci 6, 7.
- Mupirocin ointment has also been found to be effective in eradicating nasal carriage of Staphylococcus aureus, including methicillin-resistant forms 6, 7.
