Research source} While it may be a little uncomfortable, getting rid of foot fungus is usually easy, and it’s unlikely that you’ll need to seek out medical help. However, if the fungus doesn’t clear up after 2 weeks of at-home treatment, you’re in serious pain, or the fungus spreads to your nails, see a doctor. They’ll be able to prescribe you something stronger to clear the fungus up. Keep reading for exclusive insights about treating foot fungus from board-certified podiatrists.

What’s the best way to get rid of foot fungus?

Board-certified podiatrist Miguel Cunha, DPM, recommends applying an over-the-counter antifungal cream like Lamisil twice daily for 2 weeks. Keep your feet clean and dry, avoid scratching your feet, and change your shoes and socks often. If the fungus doesn’t clear in 2 weeks, visit your doctor for stronger medication.

Dr. Cunha suggests “spraying something like Lysol along the inside and outside of your shoes, which helps kill the bacteria or fungus.” He stresses that both bacteria and fungi can lead to odor, athlete's foot, or fungal nails later on.^{[6]

Keep your feet as dry as possible until the fungus is gone. Fungus thrives in dark, moist environments, so keeping your feet dry and aired out will help speed up the healing process. Don’t wear shoes unless you absolutely have to, and if you do, pick a breathable pair. Change your socks out whenever they start to get damp, and never put the same socks on after you’ve taken them off.^{[7]

How do you treat severe foot fungus?

See a doctor to get a prescription for an antifungal medication. If the rash covers most of your foot, your skin is flaking off, or the infection has spread to your nail, it’s best to see a doctor. These kinds of fungal infections typically require stronger oral medication.^{[12]

- If your nail is in a really rough shape, your doctor may prescribe you a medicated nail polish or cream.
- Your doctor may also suggest a minor surgical procedure to apply the antifungal drug directly underneath your nail or remove it entirely.
- These drugs are extremely effective, but they can cause damage to your liver in some people. Your doctor may suggest you get regular blood tests while you’re taking the antifungal medication just to keep an eye on things.

Question 5 of 6:

What causes foot fungus?

Foot fungus can be caused by walking barefoot in a public space. If you shower at the gym, change your shoes at work, or work outside with your shoes off, you may contract fungi that cause athlete’s foot.

Since these topical treatments are so low-risk, there’s no real reason to try experimenting with DIY home remedies.^{[21]

Expert Answer

Foot fungus usually results in dry, flaky skin in between the toes, a lot of times on the forefoot, but it can be anywhere on the bottom surface of the foot. It can usually be treated at home with an antifungal cream, although you may need to get a prescription-strength lotion from a doctor if that doesn't work.

There are lots of medicines, some more efficacious than others. Examples include selenium sulphide, nystatin power, oral terbinafine, or azole drugs. It depends on which part of the foot is affected (ex. sole vs. toenail).

Expert Answer

People get it due to the dampness on the foot from doing exercise or long days on your feet. You might want to try a foot powder to help avoid getting athlete's foot. If you do get athlete's foot, use one of the a over-the-counter anti-fungal treatments. If this does not work seek out the attention of a medical professional.

I had toenail fungus for years and tried everything (except oral meds that may harm the liver). What finally worked was applying original Listerine to my toes. I used a small travel spray bottle and applied it morning and night and after showering. It took several months but results were steady and visible.
I had a mountain survival instructor in the USMC tell us to use antiperspirant on the soles of our feet so we wouldn't get sweaty feet. Fungus likes to grow in damp environments, so keeping your feet dry can prevent fungus from growing.
Be careful getting salon pedicures. If the equipment isn't cleaned properly or the nail tech isn't careful, you could get ingrown toenails and/or fungus.
