Ringworm is a common fungal infection that affects the skin, causing a red, circular rash that can be itchy and uncomfortable. Despite its name, ringworm has nothing to do with worms. It is caused by a type of fungus known as dermatophytes. This condition can occur anywhere on the body, including the scalp, feet, nails, and groin area. Fortunately, there are many effective treatments available. One of the most common treatments is the use of topical ointments.
In this article, we will explore the best topical ointments for ringworm, how they work, and tips for choosing the right one for your needs.
What is Ringworm?
Ringworm, medically known as tinea, is a fungal infection that affects the outer layer of the skin. It appears as a round, red rash with a raised border, often resembling a ring. The center of the ring is typically clear or less inflamed. Ringworm can occur on various parts of the body, including the scalp (tinea capitis), feet (athlete’s foot), nails (tinea unguium), and groin area (jock itch).
The fungus that causes ringworm thrives in warm, moist environments, making it easy to contract in places like locker rooms, public showers, or by coming into contact with infected animals or people. It spreads through direct contact or by touching contaminated surfaces.
Symptoms of Ringworm
The symptoms of ringworm can vary depending on the area of the body affected. Common signs include:
- Red, circular rash with a raised border
- Itching and discomfort
- Scaly, flaky skin
- Blisters or pustules (in some cases)
- Hair loss (if the scalp is affected)
If you notice any of these symptoms, it’s important to treat ringworm as soon as possible to prevent it from spreading.
How Topical Ointments Work
Topical ointments for ringworm contain antifungal medications designed to kill the fungi that cause the infection. These medications work by disrupting the cell membranes of the fungi, which leads to their death and prevents them from spreading.
Most antifungal ointments are applied directly to the affected area of the skin. They are available in various forms, including creams, lotions, and ointments. The goal of these treatments is to reduce inflammation, relieve itching, and eliminate the fungus.
It is important to note that topical treatments should be used as directed by a healthcare professional. For most cases of ringworm, over-the-counter ointments are effective. However, severe or widespread infections may require prescription-strength treatments.
Best Topical Ointments for Ringworm
There are several excellent over-the-counter topical ointments for ringworm. Here, we’ll discuss some of the most widely recommended options.
1. Clotrimazole (Lotrimin AF)
Clotrimazole is one of the most popular antifungal treatments for ringworm. It is an over-the-counter medication that comes in cream, lotion, and powder forms. Clotrimazole works by inhibiting the growth of fungi and is effective against many types of fungal infections, including ringworm.
How it works: Clotrimazole prevents the growth of the fungi by interfering with their cell membranes. This helps eliminate the infection and reduces symptoms like itching and redness.
Application: Apply the cream or lotion to the affected area twice a day for 2 to 4 weeks. Be sure to continue treatment for the full recommended duration, even if the symptoms appear to resolve before then. This ensures that the infection is completely gone.
2. Terbinafine (Lamisil)
Terbinafine is another highly effective antifungal treatment for ringworm. It is available as a cream, gel, or spray and is often recommended for its fast-acting properties. Terbinafine works by blocking the synthesis of ergosterol, a vital component of the fungal cell membrane.
How it works: Terbinafine interferes with the production of ergosterol, causing the fungal cell membrane to break down and the fungus to die. This helps to quickly eliminate the infection and relieve associated symptoms.
Application: Apply the cream to the affected area once or twice a day. Treatment should last for at least 1 week, depending on the severity of the infection. Like other antifungal treatments, it’s important to continue use for the full duration to prevent recurrence.
3. Miconazole (Monistat-Derm)
Miconazole is an antifungal ointment that is commonly used to treat ringworm and other skin fungal infections. It works by inhibiting the production of ergosterol, which is essential for the survival of the fungi.
How it works: By disrupting the cell membrane of the fungus, miconazole prevents the fungi from reproducing and spreading. This helps to clear up the infection and provide relief from symptoms like itching and irritation.
Application: Miconazole is typically applied to the affected area twice daily. The treatment should continue for 2 to 4 weeks or as directed by your doctor. It is important to use miconazole for the full course of treatment, even if the symptoms appear to improve.
4. Ketoconazole (Nizoral)
Ketoconazole is another effective antifungal cream used to treat ringworm. It is available over-the-counter in both cream and shampoo forms. Ketoconazole works by preventing the fungus from producing the chemicals it needs to maintain its cell structure, ultimately killing the fungus.
How it works: Ketoconazole interferes with the synthesis of ergosterol, a key component of the fungal cell membrane, leading to the death of the fungus. It is particularly effective for treating fungal infections on the scalp or other hairy areas of the body.
Application: For ringworm on the skin, apply the cream once or twice daily for 2 to 4 weeks, or as directed by your healthcare provider. If you’re using the shampoo, apply it to the scalp and leave it on for 5-10 minutes before rinsing.
5. Undecylenic Acid (FungiCure)
Undecylenic acid is a naturally derived antifungal treatment that has been shown to be effective against ringworm. It is available in liquid form and is often used to treat athlete’s foot, jock itch, and ringworm.
How it works: Undecylenic acid works by disrupting the cell membranes of fungi, which prevents them from spreading and growing. It also has anti-inflammatory properties that can reduce itching and redness.
Application: Apply the liquid directly to the affected area twice daily. Treatment should be continued for 2 to 4 weeks, depending on the severity of the infection. As with other antifungal treatments, it is essential to complete the full course to ensure the infection is completely cleared.
Tips for Applying Topical Ointments
To get the best results from topical ointments for ringworm, follow these tips:
Clean the affected area: Before applying the ointment, wash the infected area with soap and water. Dry the area thoroughly before applying the medication.
Apply a thin layer: You don’t need to use a large amount of ointment. A thin layer is sufficient to cover the affected area.
Wash your hands: After applying the ointment, wash your hands to avoid spreading the fungus to other areas of your body or to others.
Avoid sharing personal items: Ringworm is contagious, so avoid sharing towels, clothing, or bedding while you’re treating the infection.
Keep the area dry: Fungi thrive in warm, moist environments. Make sure the affected area is kept dry to prevent the infection from spreading or worsening.
When to See a Doctor
While most cases of ringworm can be treated with over-the-counter ointments, some people may need prescription-strength treatment. If you experience any of the following, it’s important to consult a doctor:
- The infection does not improve after 2 weeks of treatment.
- The infection is widespread or severe.
- You have a weakened immune system (e.g., due to diabetes, HIV, or cancer treatment).
- The infection is on your scalp or nails.
A healthcare provider can recommend a stronger treatment or prescribe oral antifungal medications if necessary.
Conclusion
Ringworm is a treatable condition that can be managed effectively with topical antifungal ointments. There are several over-the-counter options available, including clotrimazole, terbinafine, miconazole, ketoconazole, and undecylenic acid. Each of these ointments works by killing the fungus responsible for the infection and relieving symptoms like itching and redness.
Be sure to apply the ointment as directed and continue treatment for the full duration to ensure the infection is completely eliminated. If you have any concerns or if the infection does not improve, seek advice from a healthcare professional.
