Ringworm is a common fungal infection that affects the skin, nails, and hair. Despite its name, it is not caused by a worm but by a fungus known as dermatophyte. Ringworm can affect anyone, regardless of age or health. The good news is that it is treatable with the right medicines. In this article, we will explore the different types of medicines used to get rid of ringworm, how they work, and other important details you should know to treat the infection effectively.
What Is Ringworm?
Before we dive into treatment options, it’s important to understand what ringworm is. Ringworm is a skin infection that often presents as circular, red, and itchy patches with raised edges. These patches can appear anywhere on the body but are most common on the scalp, feet (athlete’s foot), and groin (jock itch). The infection is caused by a group of fungi known as dermatophytes, which thrive on keratin, a protein found in skin, nails, and hair.
Ringworm is highly contagious and spreads through direct skin-to-skin contact, or contact with contaminated surfaces like towels, bedding, or clothing. It is also possible for animals to transmit the infection to humans.
Over-the-Counter Medications for Ringworm
Most cases of ringworm can be treated effectively with over-the-counter (OTC) antifungal medications. These medications come in various forms, including creams, ointments, sprays, and powders. Here are the most common types of OTC medicines for treating ringworm:
1. Topical Antifungal Creams
Topical antifungal creams are among the most effective and common treatments for ringworm. These creams contain antifungal agents that kill or stop the growth of the fungi causing the infection. Some of the most popular antifungal creams for ringworm include:
- Clotrimazole (Lotrimin AF)
- Miconazole (Monistat-Derm)
- Terbinafine (Lamisil AT)
- Tolnaftate (Tinactin)
When using topical antifungal creams, it’s important to apply the medicine directly to the affected area, as well as a small area around the ringworm to ensure the infection doesn’t spread. The medication should be used for the full recommended duration, typically for 2-4 weeks, even if the symptoms disappear earlier. Stopping treatment too soon can lead to the infection returning.
2. Antifungal Sprays and Powders
Antifungal sprays and powders can also help treat ringworm. These products are often preferred by people who experience excessive sweating or have ringworm in areas that are hard to reach, such as the feet or groin. They work similarly to antifungal creams but are easier to apply in certain areas.
Some common antifungal powders and sprays include:
- Lotrimin AF Powder Spray
- Lamisil AT Powder Spray
- Tinactin Antifungal Powder
These products should be used as directed, ensuring that the entire affected area is covered. Like creams, sprays and powders should be used consistently for the full recommended period.
Prescription Medications for Ringworm
In some cases, over-the-counter treatments may not be enough to fully treat ringworm. If the infection is severe, widespread, or located in difficult-to-treat areas like the scalp, your doctor may prescribe oral antifungal medications. These medications work from the inside out, helping to kill the fungi causing the infection.
1. Oral Antifungal Medications
Oral antifungal medications are stronger and are often used when topical treatments fail. These medications are usually prescribed for a period of 2-4 weeks, depending on the severity of the infection. Common oral antifungal drugs include:
- Terbinafine (Lamisil)
- Itraconazole (Sporanox)
- Fluconazole (Diflucan)
- Griseofulvin (Gris-PEG)
These medications may cause side effects, including nausea, headache, or liver problems. It’s important to follow the dosage instructions carefully and attend follow-up appointments with your doctor to monitor your progress.
2. Griseofulvin
Griseofulvin is one of the older oral antifungals and is still commonly used for treating ringworm, especially when the infection affects the scalp or nails. It works by preventing the fungus from growing and spreading. Griseofulvin is usually prescribed when other medications aren’t effective.
It’s important to note that griseofulvin may take longer to show results compared to newer antifungals like terbinafine. However, it is still a reliable treatment option in many cases.
Topical Treatments for Severe Cases
In severe cases of ringworm, particularly when the infection involves the scalp or nails, a combination of oral and topical treatments may be necessary. Additionally, for scalp infections, medicated shampoos can be used to complement oral treatment. These shampoos contain antifungal agents like ketoconazole or selenium sulfide, which help reduce the spread of the fungus.
Some recommended shampoos include:
- Nizoral (Ketoconazole shampoo)
- Selsun Blue (Selenium sulfide shampoo)
These shampoos can be used a few times a week until the infection clears up. It’s important to follow the directions on the label and not to use the shampoo more often than recommended.
Home Remedies for Ringworm
While medicines are essential for treating ringworm, some people look for natural remedies to help ease symptoms. Although these remedies may not be as effective as antifungal medications, they can provide relief from itching and discomfort while the infection is healing.
1. Tea Tree Oil
Tea tree oil is a natural antifungal and antibacterial agent. Some studies suggest that it may be effective in treating ringworm. It can be diluted with a carrier oil like coconut oil and applied to the affected area.
2. Apple Cider Vinegar
Apple cider vinegar has antifungal properties and is sometimes used as a home remedy for treating skin infections. You can apply diluted apple cider vinegar directly to the infected area with a cotton ball.
3. Garlic
Garlic is another natural remedy believed to have antifungal properties. Crushing fresh garlic and applying it to the affected area may help, although this remedy can be irritating to sensitive skin.
While these home remedies may help with symptoms, they should not replace proven antifungal treatments. If your ringworm persists or worsens, it’s important to seek medical attention.
Preventing the Spread of Ringworm
Ringworm is highly contagious, so it’s important to take precautions to prevent spreading the infection to others or reinfecting yourself. Here are some tips for preventing ringworm from spreading:
Keep the infected area clean and dry: Fungi thrive in moist environments, so make sure to keep the infected area dry.
Wash hands frequently: If you touch the affected area, wash your hands thoroughly with soap and water.
Avoid sharing personal items: Do not share towels, clothing, or other personal items with others.
Disinfect surfaces: Regularly disinfect surfaces that may have come into contact with the fungus, such as towels, bedding, and gym equipment.
Wear loose, breathable clothing: Tight or non-breathable clothing can create a warm, damp environment that promotes fungal growth.
Conclusion
Ringworm is a common and treatable fungal infection. The most effective treatments for ringworm include antifungal creams, powders, and sprays, as well as oral medications for more severe cases. If over-the-counter treatments do not work, your doctor may prescribe oral antifungal drugs or additional topical treatments. While medications are essential for treating the infection, it’s also important to practice good hygiene and prevent the spread of the fungus.
If you suspect you have ringworm, it’s always best to consult with a healthcare provider for an accurate diagnosis and treatment plan. With the right medicine and proper care, ringworm can be treated effectively, and you can get back to your normal routine.
