A Rash Decision: How To Cure Ringworm

Over-the-counter antifungal creams usually get the job done

Treating ringworm with a topical cream

Being told you have a case of ringworm is enough to make your skin crawl. Thankfully, the condition is not nearly as creepy-crawly as it sounds. There aren’t even any worms involved. (Cue sigh of relief.)

The skin infection is caused by a fungus … which, come to think of it, does make ringworm sound a wee bit icky.

But if you have ringworm, know that you’re not alone. It’s estimated that 20% to 25% of the world’s population has some form of ringworm at any given moment. (As you might have guessed, the infection is very contagious.)

So, how can you conquer ringworm? Let’s find out from dermatologist Alok Vij, MD.

How to get rid of ringworm

Ringworm causes red, ring-shaped patches on your skin. The red splotches typically have a wavy, wormlike border that’s raised or scaly, explains Dr. Vij. The rash is usually a little itchy (but not always).

If you have signs of ringworm, you probably want it gone yesterday. The good news? “It’s generally easy to treat,” says Dr. Vij.

Look for over-the-counter (OTC) antifungal creams such as Tinactin® (tolnaftate topical) or Lotramin® (clotrimazole). These products are often found in the foot care aisle and marketed for athlete’s foot, one variation of ringworm. (More on that in a bit.)

These creams will:

  • Clear it up: Use it twice a day, and the infection should start clearing within a few days.
  • Wipe it out: Keep using the cream morning and night for a month to fully wipe out the fungus and prevent it from making a repeat performance. “Using the creams consistently is the key,” Dr. Vij emphasizes.

Most often, an OTC treatment works well to clear up ringworm. If it doesn’t, check in with a healthcare provider. You may have a robust ringworm infection that requires prescription treatment.

Don’t use an over-the-counter hydrocortisone skin cream on ringworm, as it may worsen the infection.

Will ringworm go away on its own?

The short answer? Don’t bet on it.

A mild case of ringworm may clear up on its own in a few weeks if you’re lucky. And that’s only if you’re careful in following precautionary self-care steps, such as keeping the infected skin clean and dry.

But it’s more likely that the easily transmissible infection will spread to other areas of your body if you don’t treat it. It can pop up on any patch of skin, too, including your scalp (very common in kiddos), your feet (where it’s known as athlete’s foot) or your groin (hello, jock itch).

Do home remedies work?

Apple cider vinegar offers some wonderful potential health benefits. Curing ringworm, however, is NOT among them despite what online chatter and old folklore might lead you to believe, says Dr. Vij. In fact, using apple cider vinegar on ringworm may result in open sores or inflammation.

Other touted natural home remedies for ringworm — including aloe vera, garlic, tea tree oil, turmeric and coconut oil — also aren’t scientifically proven and backed.

Tips to tame (and prevent) ringworm

Using antifungal creams and medications is your best bet to cure ringworm fast. Use these strategies to help stop those telltale red ringworm rings from migrating or to avoid the infection in the first place.

Wash up

After touching a ringworm rash for any reason, including applying antifungal cream, wash your hands before you touch another part of your body. (Or somebody else’s body. Your friends will thank you.)

Shower after exercise

Sweating can spread ringworm droplet by droplet. Minimize the risk by showering immediately after a drippy workout. (That’s a good idea even without ringworm, by the way.)

Afterward, make sure to dry off thoroughly and pay attention to hard-to-reach areas. (Like between your toes.) Use two towels, too — one for areas with ringworm and the other for the rest of your body.

Protect your feet

Locker rooms, gyms and pools are breeding grounds for the fungi that cause ringworm and other infections. Wear shower shoes and avoid going barefoot in those settings to keep your tootsies healthy.

If you do get athlete’s foot, try to wear open-toed shoes until the infection clears to keep the area dry. (Air circulation is your friend!)

Laundry

Regularly wash all linens, towels and clothing that come into contact with a ringworm infection. Go ahead and crank up the water temp in the washing machine, too. You want to scorch those fungi.

Scrub surfaces

Use disinfectant sprays or bleach to kill ringworm-causing fungi that might be contaminating bathroom countertops, door knobs or other surfaces.

Check your pets

Ringworm isn’t just a problem for people. Dogs and cats can get and spread the skin infection, too. Ditto for cows, goats, pigs, sheep and horses. The fungus may leave hairless patches on infected animals.

If you suspect your pet or an animal in your care has ringworm, make sure it’s seen by a veterinarian for treatment.

When to see a doctor about ringworm

It doesn’t take long to identify a ringworm infection given its distinctive and scaly ring-shaped rash. But getting rid of it often requires a bit of patience.

Mild cases often clear up within a few weeks, especially if you treat it with an OTC antifungal cream. More serious infections may linger for a few months even if you’re taking the necessary steps to knock them out.

Contact a healthcare provider if antifungal creams aren’t working on your ringworm or if the infection:

  • Begins to swell and turn an angrier shade of red.
  • Spreads to other areas of your body.
  • Appears on your scalp.
  • Occurs during pregnancy.

“Most ringworm infections can be treated with an over-the-counter antifungal cream, proper care and a little patience,” reassures Dr. Vij. “Don’t ignore it, though, or you may turn a small infection into a much larger problem.”
