What is Retapamulin: Uses, Dosage, Side Effects and More

Retapamulin is a topical antibiotic cream that treats bacterial skin infections, particularly impetigo in children and adults. This gentle yet effective medication works by stopping harmful bacteria from making proteins they need to survive and multiply on your skin.

You might find this medication helpful if you're dealing with those crusty, honey-colored sores that seem to spread quickly, especially around the nose and mouth area. It's specifically designed to target the bacteria that cause these uncomfortable skin infections without being too harsh on delicate skin.

What is Retapamulin?

Retapamulin belongs to a unique class of antibiotics called pleuromutilins, which work differently from many other topical antibiotics. It's a prescription-only cream that comes in a 1% concentration, meaning every gram contains 10 milligrams of the active ingredient.

This medication was specifically developed to fight skin bacteria like Staphylococcus aureus and Streptococcus pyogenes. These are the main culprits behind impetigo and other superficial skin infections that can make you or your child quite uncomfortable.

What makes retapamulin special is its targeted approach. Unlike broader antibiotics that might affect many types of bacteria, this cream focuses on the specific bacteria causing your skin infection while being gentler on your skin's natural protective barrier.

What is Retapamulin Used For?

Retapamulin primarily treats impetigo, a common bacterial skin infection that creates red sores which quickly burst and form honey-colored crusts. You'll most often see this infection in children, though adults can certainly get it too.

The medication is particularly helpful for treating small areas of infected skin, typically no larger than 100 square centimeters (about the size of your palm). This makes it perfect for those localized patches of impetigo that tend to appear around the nose, mouth, or other areas where skin gets irritated.

Your doctor might also prescribe retapamulin for other minor bacterial skin infections when they determine it's the right choice for your specific situation. However, it's important to note that this medication only works against bacterial infections, not viral or fungal skin problems.

How Does Retapamulin Work?

Retapamulin works by interfering with the bacteria's ability to make essential proteins needed for survival. Think of it as disrupting the bacteria's protein-making factory, which eventually leads to their death.

This medication is considered moderately strong among topical antibiotics. It's powerful enough to effectively clear bacterial infections but gentle enough for use on sensitive areas like the face and in children as young as 9 months old.

The cream penetrates into the affected skin layers where the bacteria are multiplying. Once there, it binds to specific parts of the bacterial cells and stops them from functioning properly, allowing your body's natural healing processes to take over.

How Should I Take Retapamulin?

Apply retapamulin cream directly to the affected area twice daily, about 12 hours apart. You'll want to clean the infected area gently with mild soap and water before applying the medication, then pat the skin dry with a clean towel.

Use clean hands or a clean applicator to apply a thin layer of cream to the infected area and about half an inch around it. Don't rub it in vigorously - just spread it evenly and let it absorb naturally into your skin.

You don't need to take this medication with food or milk since it's applied to your skin rather than swallowed. However, you should avoid getting the cream in your eyes, nose, mouth, or on mucous membranes, as this can cause irritation.

After applying the cream, you can cover the area with a clean, dry bandage if your doctor recommends it. Otherwise, leave the area uncovered to allow air circulation, which can help with healing.

How Long Should I Take Retapamulin For?

Most people use retapamulin for 5 days, which is typically enough time to clear up impetigo and similar bacterial skin infections. Your doctor will give you specific instructions based on your particular situation and the severity of your infection.

It's crucial to complete the full course of treatment even if your skin looks better after just a couple of days. Stopping too early can allow the bacteria to return and potentially become resistant to the medication.

If you don't see improvement after 3-4 days of treatment, or if your infection seems to be getting worse, contact your healthcare provider. They may need to reassess your condition or consider alternative treatments.

What Are the Side Effects of Retapamulin?

Most people tolerate retapamulin quite well, but like any medication, it can cause side effects in some individuals. The good news is that serious side effects are uncommon with this topical antibiotic.

Here are the most common side effects you might experience, keeping in mind that many people have no side effects at all:

• Mild burning or stinging at the application site
• Skin redness or irritation
• Itching around the treated area
• Dry skin or slight skin peeling
• Headache (less common)
• Runny nose or cold-like symptoms

These reactions are usually mild and temporary, often improving as your skin adjusts to the medication. If they persist or become bothersome, don't hesitate to discuss them with your healthcare provider.

Some rare but more serious side effects require immediate medical attention. While these occur infrequently, it's important to be aware of them:

• Severe allergic reactions with rash, hives, or difficulty breathing
• Severe skin irritation or blistering
• Signs of a secondary infection (increased redness, warmth, or pus)
• Swelling of the face, lips, tongue, or throat

If you experience any of these serious side effects, stop using the medication and seek medical help immediately. These reactions are rare but can be serious if not treated promptly.

Who Should Not Take Retapamulin?

Retapamulin isn't suitable for everyone, and there are certain situations where your doctor might choose a different treatment option. The most important consideration is whether you have any known allergies to retapamulin or similar medications.

You should avoid retapamulin if you're allergic to any pleuromutilin antibiotics. If you've had reactions to other topical antibiotics in the past, make sure to tell your doctor about these experiences.

This medication should be used with extra caution in these situations:

• Pregnancy - while studies suggest it's likely safe, your doctor will weigh the benefits and risks
• Breastfeeding - small amounts might pass into breast milk
• Infants under 9 months old - safety hasn't been established in this age group
• Large areas of infected skin - the medication is only approved for small areas
• Deep or severe infections - these might need oral antibiotics instead

If you have a compromised immune system or take medications that suppress immunity, your doctor will monitor you more closely during treatment to ensure the infection clears properly.

Retapamulin Brand Names

Retapamulin is most commonly available under the brand name Altabax in the United States. This is the original brand name under which the medication was first marketed and is still widely recognized by healthcare providers.

You might also find generic versions of retapamulin cream available at some pharmacies. These contain the same active ingredient and work just as effectively as the brand-name version, often at a lower cost.

When discussing this medication with your pharmacist or doctor, you can refer to it by either its generic name (retapamulin) or brand name (Altabax). They'll know exactly what you're talking about and can help you find the most cost-effective option.

Retapamulin Alternatives

If retapamulin isn't the right choice for your situation, several other topical antibiotics can effectively treat bacterial skin infections. Your doctor might consider these alternatives based on your specific needs and medical history.

Mupirocin (Bactroban) is probably the most common alternative for treating impetigo. It's been around longer than retapamulin and has a well-established safety profile, though some bacteria have developed resistance to it over time.

Other topical options your doctor might consider include:

• Fusidic acid cream - effective against similar bacteria but not available in all countries
• Neomycin-based creams - though these can cause more allergic reactions
• Bacitracin ointment - available over-the-counter but less effective for extensive infections

For more severe or widespread infections, your doctor might recommend oral antibiotics like cephalexin or clindamycin instead of topical treatments. The choice depends on the extent of your infection and your individual circumstances.

Is Retapamulin Better Than Mupirocin?

Both retapamulin and mupirocin are excellent choices for treating bacterial skin infections, and studies show they're similarly effective for clearing impetigo. The "better" choice really depends on your specific situation and any previous experiences with these medications.

Retapamulin has some advantages in that it works through a different mechanism than mupirocin, which means it can be effective against some bacteria that have become resistant to mupirocin. This makes it a valuable option when mupirocin hasn't worked well in the past.

Mupirocin has been available longer and has extensive safety data, especially in children. It's also often less expensive than retapamulin, which can be an important consideration for some families.

Your doctor will consider factors like the specific bacteria causing your infection, your medical history, any allergies you might have, and cost considerations when choosing between these medications. Both are safe and effective when used as prescribed.
