Fusiderm Cream, Ointment & Gel
A comprehensive guide to the topical antibiotic Fusiderm, used to treat bacterial skin infections.
Quick Facts
What is Fusiderm and what is it used for?
Fusiderm is a topical antibiotic that comes in the form of a cream, ointment, or gel. It contains the active ingredient fusidic acid (in the cream and gel) or sodium fusidate (in the ointment), which works by stopping the growth of or killing bacteria that cause skin infections. The medication is used to treat a wide range of bacterial infections affecting the skin’s surface.
- Impetigo: A common skin infection that causes sores and blisters, especially around the mouth and nose.
- Infected Dermatitis: Such as cases of eczema or contact dermatitis that develop a secondary bacterial infection.
- Infected Minor Wounds and Burns: Helps prevent and treat infection in superficial wounds and minor burns.
Thanks to its effectiveness against a range of common bacteria, Fusiderm is a primary choice for treating many primary and secondary bacterial skin problems.
How to Use and Dosage
Always use Fusiderm as prescribed by your doctor or pharmacist. This medication is for external use on the skin only and should not be swallowed or placed inside the body. It is important to wash your hands thoroughly before and after each use.
- Usual Dose: Apply a thin layer of the cream or ointment to the affected area three to four times daily.
- Application: Gently rub the product into the skin until it is absorbed.
- Covering with a Dressing: The affected area can be covered with a sterile dressing if necessary, in which case the frequency of use may be reduced.
- If you forget a dose: If you miss a dose, apply it as soon as you remember, then continue with your usual schedule.
You must complete the course of treatment prescribed by your doctor, even if symptoms disappear, to ensure the infection is completely eliminated and prevent its return.
Potential Side Effects
Like all medicines, Fusiderm may cause some side effects, but they do not affect everyone. Most effects are localized and mild.
- Common Symptoms: Mild skin irritation, itching, a burning sensation, or redness at the site of application.
- Uncommon Symptoms: Rash, dry skin.
- Serious Allergic Symptoms (Rare): Seek immediate medical help if you experience difficulty breathing, swelling of the face or throat, or a severe, widespread rash.
If any of the side effects worsen, or if you notice any other unlisted symptoms, you should inform your doctor or pharmacist.
Important Warnings and Precautions
Before using Fusiderm, you must inform your doctor of your full medical history, especially if you have any drug allergies.
- Allergy: Do not use the medication if you have a known allergy to fusidic acid, sodium fusidate, or any of the other ingredients.
- Use Near Eyes: Extreme caution should be taken when using the product near the eyes. If the medication accidentally gets into your eyes, rinse them immediately with a large amount of cold water.
- Long-term Use: Using the medication for long periods or in large amounts may increase the risk of developing resistant bacterial strains or skin sensitization to the drug.
- Pregnancy and Lactation: Consult a doctor before using the medication during pregnancy or breastfeeding to weigh the benefits against the risks.
The medication should be stored out of reach of children and at a temperature not exceeding 30°C.
Frequently Asked Questions (FAQ)
1. What is the difference between Fusiderm cream and Fusiderm ointment?
The main difference lies in the base of each preparation. The cream has a water base, making it lighter and easier to spread and absorb, which is suitable for moist or weeping skin areas and for use on the face and scalp. The ointment has an oil base, which makes it thicker and provides a more protective and moisturizing layer.
The ointment is preferred for dry, scaly areas, or those needing extra protection, such as wounds covered with dressings. The doctor determines the most suitable type based on the nature and location of the infection.
2. Can Fusiderm be used to treat acne?
Yes, Fusiderm can be used in some cases of acne, especially the inflammatory type caused by the bacteria (Propionibacterium acnes). Fusidic acid works to kill these bacteria and reduce the inflammation associated with pimples and pustules. It is usually used as a short-term spot treatment for inflamed pimples.
However, Fusiderm is not considered a primary long-term treatment for acne, as prolonged use may lead to resistant bacteria. A dermatologist should be consulted to determine the appropriate treatment plan for your condition, which may include other medications.
3. How long should I use Fusiderm?
The duration of treatment depends on the severity and type of infection, and you should always follow your doctor’s recommendations. Generally, topical antibiotics like Fusiderm are used for a relatively short period, typically ranging from 7 to 10 days. This duration is usually sufficient to eliminate the bacterial infection.
It is very important to complete the full prescribed course of treatment, even if symptoms begin to improve early. Stopping the medication prematurely may allow the remaining bacteria to grow back, leading to a recurrence of the infection or the development of antibiotic resistance.
4. Can Fusiderm be used on open wounds?
Yes, Fusiderm can be used on superficial open wounds, such as scrapes or small cuts, to prevent a bacterial infection or to treat an existing one. The medication helps keep the wound free of bacteria and promotes the healing process.
Before applying the ointment or cream, the wound should be gently cleaned with soap and water or an antiseptic solution and dried thoroughly. It is not recommended for deep or large wounds or those requiring stitches, as these conditions require specialized medical care.
5. Does Fusiderm treat fungal infections?
No, Fusiderm is an antibiotic effective only against bacteria and has no effect on fungi or viruses. Using it to treat a fungal infection, such as ringworm (Tinea) or athlete’s foot, will not be effective and may worsen the problem by allowing fungi to grow without competition from bacteria.
If you are unsure about the nature of your skin inflammation, it is essential to consult a doctor for a proper diagnosis. The doctor will prescribe an antifungal medication if the infection is fungal.
6. Is Fusiderm safe for children and infants?
Yes, Fusiderm is generally considered safe for use in children and infants to treat bacterial skin infections like impetigo. A very small amount of the drug is absorbed through the skin into the bloodstream, which reduces the risk of systemic side effects.
However, it should always be used under medical supervision in this age group. When used on infants in the diaper area, diapers can act as an occlusive dressing, increasing drug absorption, so it is important to follow the doctor’s instructions precisely.
7. Can I use Fusiderm with other topical medications?
Caution should be exercised when using Fusiderm with other topical preparations on the same area of skin. It may interact with some medications, or one may affect the absorption of the other. For example, if you are using a corticosteroid cream, your doctor may advise you to leave a time interval between applying each one.
It is always best to inform your doctor or pharmacist of all topical medications and preparations you are using, including cosmetic or herbal products, to get guidance on how to use them together safely and effectively.
8. What should I do if the cream gets in my eyes?
If Fusiderm accidentally gets into your eyes, it may cause a burning sensation and irritation. You should immediately rinse your eyes with a large amount of cold water or saline solution for 10-15 minutes to remove any residue of the product.
If irritation or redness persists, or if you notice blurred vision after rinsing, you should contact your doctor or visit the nearest emergency department. To avoid this, always be careful when applying the medication on the face near the eye area.
9. Do I need a prescription to buy Fusiderm?
Dispensing policies vary from country to country. In many countries, Fusiderm is considered a prescription-only medication to ensure it is used correctly for appropriate conditions and to avoid the growing problem of antibiotic resistance.
Even if it is available without a prescription in your area, it is always best to consult a doctor or pharmacist before using it to confirm that the infection is indeed bacterial and that this is the appropriate treatment for it.
10. What are the signs of an allergy to Fusiderm?
Although rare, allergic reactions to Fusiderm can occur. Mild signs include worsening itching, redness, and a rash in the treated area. Signs of a severe and serious allergic reaction require immediate medical attention.
These serious signs include: widespread hives, swelling of the face, lips, tongue, or throat, and difficulty breathing or swallowing. If you experience any of these symptoms, stop using the medication and seek emergency medical help.
