What is Mupirocin Nasal Ointment Used For?
Mupirocin nasal ointment is used to prevent or treat bacterial infections of the nose [1]. It is specifically prescribed to help eliminate Staphylococcus aureus, including methicillin-resistant Staphylococcus aureus (MRSA), from the nasal passages of patients [2][3]. This is often done as a decolonization measure before surgical procedures or for individuals who are carriers of MRSA [2][3][4].
How Does Mupirocin Nasal Ointment Work?
Mupirocin is an antibiotic that works by inhibiting bacterial protein synthesis [5]. It targets an enzyme called isoleucyl-tRNA synthetase, which is essential for bacteria to build proteins [5]. By disrupting this process, mupirocin effectively stops the growth and multiplication of susceptible bacteria [5].
Who is Prescribed Mupirocin Nasal Ointment?
This ointment is typically prescribed to individuals who are carriers of Staphylococcus aureus, particularly MRSA, in their noses [2][3][4]. Patients undergoing certain surgical procedures, such as orthopedic or cardiothoracic surgery, may be given mupirocin nasal ointment to reduce the risk of post-operative infection [4]. It is also used for individuals identified as nasal carriers of MRSA to help eradicate the bacteria from their nasal passages [2][3].
How is Mupirocin Nasal Ointment Applied?
Mupirocin nasal ointment is applied directly into the nostrils [1]. A small amount of the ointment is typically inserted into each nostril two to three times a day for a prescribed duration, often for five days [1][6]. It is important to follow the specific instructions provided by a healthcare professional.
What are the Potential Side Effects?
The most common side effects of mupirocin nasal ointment are localized to the application site and can include nasal irritation, burning, itching, and stinging [1]. Some individuals may experience headache or a sore throat [1]. Serious allergic reactions are rare but can occur and require immediate medical attention [1].
How Does Mupirocin Nasal Ointment Compare to Other Treatments for Nasal MRSA?
Mupirocin is a well-established treatment for nasal decolonization of MRSA [2][3]. While other antibiotics or antiseptic nasal preparations may exist, mupirocin remains a primary choice due to its efficacy and spectrum of activity against Staphylococcus aureus [2][3]. The choice of treatment can depend on factors such as local resistance patterns and individual patient profiles.
What is the Duration of Treatment with Mupirocin Nasal Ointment?
Treatment with mupirocin nasal ointment typically lasts for five days [1][6]. However, the exact duration can vary based on the prescribing physician's instructions and the patient's specific condition.
What Happens if I Miss a Dose of Mupirocin Nasal Ointment?
If a dose of mupirocin nasal ointment is missed, apply it as soon as remembered. However, if it is close to the time for the next dose, skip the missed dose and continue with the regular dosing schedule. Do not double the dose to catch up [1].
Are There Any Contraindications for Mupirocin Nasal Ointment?
Mupirocin nasal ointment should not be used by individuals with a known hypersensitivity to mupirocin or any of the ingredients in the ointment [1].
What is the Availability and Cost of Mupirocin Nasal Ointment?
Mupirocin nasal ointment is available by prescription and its cost can vary depending on the pharmacy, insurance coverage, and whether a generic version is used [7].
