Ringworm is a common fungal infection that can affect various parts of your body, including the skin, scalp, feet, and nails. It is caused by a group of fungi known as dermatophytes. Despite its name, ringworm has nothing to do with worms. It gets its name from the circular, red, and itchy rash it causes. Treating ringworm involves the use of antifungal medications. In this article, we will explore the different medicines available to treat ringworm, how they work, and how to use them for effective treatment.
What is Ringworm?
Ringworm is a superficial fungal infection that can cause a rash in the shape of a ring. It is also called “tinea” followed by the area it affects, such as tinea corporis (for the body), tinea pedis (for the feet, also known as athlete’s foot), and tinea capitis (for the scalp). The infection spreads through direct contact with an infected person, animal, or contaminated surfaces like towels, clothing, or shower floors.
How Do Antifungal Medicines Work?
Antifungal medicines work by targeting the fungi that cause ringworm. Fungi are different from bacteria, so they require specific treatment. These medications prevent the fungi from growing and multiplying. Some antifungal medicines attack the fungal cell wall, while others prevent the fungi from using essential nutrients. This stops the infection from spreading and helps the body heal.
Over-the-Counter Antifungal Creams and Ointments
The first line of treatment for most cases of ringworm is over-the-counter (OTC) antifungal creams, ointments, or sprays. These medications are easily accessible at most drugstores and are often effective in treating mild to moderate infections.
Common OTC Antifungal Medicines for Ringworm
Clotrimazole (Lotrimin)
How it works: Clotrimazole is an antifungal cream that works by inhibiting the growth of fungi.
How to use it: Apply a thin layer of the cream to the affected area twice daily. Continue using it for at least 2-4 weeks, even if the rash seems to improve. Stopping early can lead to a recurrence of the infection.
Terbinafine (Lamisil)
How it works: Terbinafine is available as both a cream and a spray. It stops the growth of fungi by interfering with their cell membranes.
How to use it: Apply the cream or spray to the infected area once or twice a day. Similar to clotrimazole, it should be used for 2-4 weeks for best results.
Miconazole (Desenex, Micatin)
How it works: Miconazole is another antifungal agent that works to stop the growth of the fungi.
How to use it: Apply a thin layer of miconazole cream to the affected area twice daily. It is essential to continue use for the prescribed time, even if the symptoms clear up sooner.
Tinea Pedis Sprays (Tinactin)
How it works: These are antifungal sprays designed for athlete’s foot but can be used for ringworm on the feet as well. They work similarly to other antifungal treatments by preventing the fungus from growing.
How to use it: Spray the affected area once or twice daily for a period of at least 2 weeks.
Butenafine (Lotrimin Ultra)
How it works: Butenafine is a newer antifungal cream that works by stopping the production of ergosterol, a compound necessary for fungal cell membranes.
How to use it: It is typically applied once daily for one to two weeks. As with other treatments, continue using it for the entire duration to ensure the fungus is completely eradicated.
Prescription Medications for More Severe Cases
If ringworm does not improve with OTC treatments, or if the infection is severe or widespread, a doctor may prescribe stronger medications. These prescriptions can be oral pills or stronger topical treatments.
Oral Antifungal Medications
For more persistent or widespread cases, doctors may recommend oral antifungal medications. These medicines work from the inside out and are often necessary for treating ringworm of the scalp, nails, or extensive body infections.
Terbinafine (Lamisil)
How it works: Terbinafine is also available in oral form, and it is one of the most commonly prescribed medications for treating ringworm.
How to use it: A typical course of treatment involves taking one 250 mg tablet once a day for 2-4 weeks, depending on the severity of the infection. A doctor will determine the exact dosage and duration.
Griseofulvin (Gris-PEG)
How it works: Griseofulvin is another oral antifungal that has been used for decades to treat fungal infections. It works by interfering with fungal cell division.
How to use it: This medication is often prescribed for ringworm of the scalp and nails. It is usually taken once or twice a day for 4-6 weeks or longer, depending on the infection.
Fluconazole (Diflucan)
How it works: Fluconazole is a potent antifungal medication used to treat severe or persistent fungal infections.
How to use it: Typically, fluconazole is taken as a single dose or a few doses over a period of time, depending on the severity of the infection. It is not commonly the first line of treatment, but it can be effective when other medications fail.
Itraconazole (Sporanox)
How it works: Itraconazole is another oral antifungal used to treat more severe cases of ringworm, particularly in the nails or scalp.
How to use it: It is taken as a daily pill for several weeks. The doctor will determine the appropriate dosage and length of treatment.
Topical Antifungal Solutions for Ringworm of the Scalp
When ringworm affects the scalp (tinea capitis), stronger topical treatments may be needed. These treatments typically include antifungal shampoos or creams designed to penetrate hair follicles and treat the infection more effectively.
Ketoconazole (Nizoral) Shampoo
How it works: Ketoconazole shampoo is commonly prescribed for fungal infections of the scalp. It helps to eliminate the fungi that cause ringworm.
How to use it: Use the shampoo twice a week for several weeks. Apply it to wet hair, leave it on for 5-10 minutes, and then rinse thoroughly.
Ciclopirox (Loprox) Cream or Gel
How it works: Ciclopirox is a topical antifungal treatment used for infections of the scalp and skin. It prevents the growth of fungi by affecting their cellular processes.
How to use it: Apply the cream or gel directly to the affected areas on the scalp once or twice a day.
Home Remedies and Alternative Treatments
While antifungal medications are typically the most effective way to treat ringworm, some people may seek natural remedies to help relieve symptoms. It is important to note that these alternatives should not replace medical treatments but may be used alongside them to soothe the skin and prevent the spread of infection.
Tea Tree Oil
Tea tree oil has antifungal properties and may help to reduce the symptoms of ringworm. It should be diluted with a carrier oil like coconut oil before applying to the skin to avoid irritation.
Apple Cider Vinegar
Apple cider vinegar has natural antifungal properties and may be applied to the infected area. It is believed to help reduce itching and inflammation caused by the fungus. Like tea tree oil, it should be diluted before use.
Garlic
Garlic is often touted for its antimicrobial properties. Some people use crushed garlic or garlic oil on the infected area to reduce the growth of the fungi. However, be cautious as garlic can sometimes cause skin irritation.
How to Prevent Ringworm Infections
Preventing the spread of ringworm is essential to avoid reinfection. Here are some tips to keep in mind:
Keep your skin clean and dry: Fungi thrive in warm, moist environments. Make sure to dry your skin thoroughly after bathing or sweating.
Avoid sharing personal items: Do not share towels, combs, or clothing with others, especially if they have ringworm.
Wear breathable clothing: Clothes made of natural fibers, such as cotton, allow your skin to breathe and reduce the risk of fungal infections.
Treat pets if necessary: If your pet has ringworm, it is important to treat them as well. Fungal infections can spread from animals to humans.
Disinfect common surfaces: Regularly clean shared surfaces, such as gym equipment, locker rooms, and public showers, to prevent the spread of the infection.
When to See a Doctor
If the ringworm infection is not improving after a few weeks of treatment, or if it is spreading rapidly, it is important to see a doctor. They may prescribe a stronger oral medication or investigate other possible causes for your symptoms. Additionally, ringworm on the scalp or nails may require special treatment.
Conclusion
Ringworm is a treatable condition that typically responds well to antifungal medications. Over-the-counter creams and ointments are often effective for mild cases, while more severe or widespread infections may require prescription oral medications. Following the prescribed treatment plan and practicing good hygiene can help ensure that the infection clears up fully and does not return. If you have any concerns or if your infection persists, consult with a healthcare professional for further guidance.
