What Is Bactroban Cream Used For?
Bactroban cream is primarily used to treat skin infections caused by bacteria, notably Staphylococcus aureus and Streptococcus pyogenes. It works by stopping the growth of these bacteria, thereby clearing up the infection.
Introduction to Bactroban Cream
Bactroban, also known by its generic name mupirocin, is a topical antibiotic. It’s widely prescribed by doctors to combat various skin infections. Unlike oral antibiotics, Bactroban is applied directly to the affected area, minimizing systemic effects and focusing the medication where it’s needed most. This targeted approach helps prevent the overgrowth of resistant bacteria in the gut, a common concern with oral antibiotics.
What Types of Infections Does Bactroban Treat?
Bactroban is effective against several types of skin infections, including:
- Impetigo: A highly contagious skin infection, commonly seen in children, characterized by red sores that quickly rupture, ooze, and form a honey-colored crust.
- Folliculitis: An infection of the hair follicles, often appearing as small, red bumps or pimples around hair shafts.
- Boils (Furuncles): Painful, pus-filled bumps under the skin caused by bacteria entering through hair follicles or breaks in the skin.
How Does Bactroban Work?
Bactroban inhibits bacterial protein synthesis by specifically binding to bacterial isoleucyl-tRNA synthetase. This enzyme is essential for the bacteria to create the proteins needed for growth and reproduction. By blocking this enzyme, Bactroban essentially stops the bacteria from multiplying, allowing the body’s immune system to clear the infection.
The Benefits of Using Bactroban Cream
Using Bactroban cream offers several advantages:
- Targeted treatment: Applied directly to the affected area, minimizing side effects.
- Effective against common skin bacteria: Specifically targets Staphylococcus and Streptococcus species.
- Reduces the risk of systemic antibiotic resistance: Topical application limits exposure compared to oral antibiotics.
- Relatively quick results: Symptoms often improve within a few days of use.
How to Apply Bactroban Cream Correctly
Proper application is crucial for Bactroban’s effectiveness:
- Wash your hands thoroughly before and after applying the cream.
- Clean the affected area with soap and water, and pat it dry.
- Apply a thin layer of Bactroban cream to the infected skin.
- Cover the treated area with a sterile bandage or gauze, if desired.
- Repeat application as directed by your doctor, usually two to three times daily.
Potential Side Effects of Bactroban Cream
While generally well-tolerated, Bactroban cream can cause some side effects:
- Local irritation: Burning, stinging, itching, or redness at the application site.
- Dry skin: Peeling or flaking of the skin around the treated area.
- Allergic reaction: Rarely, some individuals may experience an allergic reaction with symptoms like rash, hives, or swelling.
If you experience any severe or persistent side effects, discontinue use and consult your doctor.
Common Mistakes to Avoid When Using Bactroban
To ensure Bactroban is effective and safe, avoid these common mistakes:
- Using it for viral or fungal infections: Bactroban is an antibiotic and only works against bacterial infections.
- Applying too much cream: A thin layer is sufficient; excessive application won’t speed up healing.
- Discontinuing use prematurely: Complete the full course of treatment as prescribed, even if symptoms improve.
- Sharing the cream with others: Bactroban is prescribed for a specific infection; sharing can spread bacteria and delay proper treatment.
- Using it on deep wounds or burns: Bactroban is intended for superficial skin infections.
Bactroban vs. Oral Antibiotics: Which is Better?
| Feature | Bactroban Cream (Topical) | Oral Antibiotics |
|---|---|---|
| Application | Directly to the affected area | Taken orally (pill or liquid) |
| Target | Localized skin infections | Systemic infections, including those beneath the skin |
| Side Effects | Primarily local irritation | Potential for gastrointestinal upset, allergic reactions, and systemic effects |
| Resistance Risk | Lower risk of contributing to systemic antibiotic resistance | Higher risk of contributing to systemic antibiotic resistance |
| Severity of Infection | Mild to moderate superficial infections | More severe infections or those not responding to topical treatment |
Frequently Asked Questions (FAQs)
Can I use Bactroban cream on my face?
While Bactroban ointment is sometimes used on the face, Bactroban cream should be used with caution and only under the direction of a doctor. It is important to avoid getting the cream in your eyes, nose, or mouth. The skin on the face is generally more sensitive, so irritation is possible.
How long does it take for Bactroban to work?
Most people notice an improvement in their symptoms within 3-5 days of starting Bactroban treatment. However, it is crucial to complete the full course of treatment, even if your skin looks better, to ensure the infection is completely eradicated.
What should I do if I miss a dose of Bactroban cream?
Apply the missed dose as soon as you remember. However, if it is almost time for your next scheduled dose, skip the missed dose and continue with your regular dosing schedule. Do not apply a double dose to make up for the missed one.
Can I use Bactroban cream during pregnancy or breastfeeding?
It is important to consult with your doctor before using Bactroban cream during pregnancy or breastfeeding. While Bactroban is generally considered to have low systemic absorption, meaning very little of the medication enters the bloodstream, your doctor can assess the risks and benefits for your specific situation.
Can Bactroban be used to treat MRSA?
Yes, Bactroban is often effective against methicillin-resistant Staphylococcus aureus (MRSA), particularly for skin infections. However, the effectiveness can vary depending on the specific strain of MRSA and its antibiotic susceptibility. Your doctor will determine if Bactroban is the appropriate treatment for your MRSA infection.
Is it safe to use Bactroban cream on children?
Bactroban cream is generally safe for children over the age of 2 months. The dosage and duration of treatment should be determined by a pediatrician or healthcare provider. Always follow their instructions carefully.
Can I buy Bactroban cream over the counter?
No, Bactroban cream is a prescription-only medication in most countries, including the United States. You will need to see a doctor to obtain a prescription.
What are the signs of an allergic reaction to Bactroban cream?
Signs of an allergic reaction can include rash, hives, itching, swelling (especially of the face, tongue, or throat), dizziness, and difficulty breathing. If you experience any of these symptoms, discontinue use immediately and seek medical attention.
Can I apply makeup over Bactroban cream?
It’s generally recommended to avoid applying makeup directly over the area treated with Bactroban cream. Makeup can trap bacteria and potentially worsen the infection. If you must wear makeup, apply it to areas that are not infected.
How should I store Bactroban cream?
Store Bactroban cream at room temperature, away from heat and direct light. Keep it out of the reach of children and pets. Do not store it in the bathroom, where moisture can affect its effectiveness.
What happens if I accidentally swallow Bactroban cream?
While Bactroban is intended for topical use, swallowing a small amount is unlikely to cause serious harm. However, it is best to contact your doctor or poison control center for advice, especially if a large amount was ingested.
Can I use Bactroban cream on cuts or wounds?
Bactroban cream is best suited for superficial skin infections. For deeper cuts, wounds, or burns, consult a doctor. They may recommend a different type of treatment to prevent infection and promote healing.
