Most of these creams or ointments are meant to be used twice a day for about 2 weeks. You may need to keep using the medication for 1-2 weeks after the rash clears up to keep it from returning.

Always wash your hands carefully after you’re done applying the ointment!
Some antifungal powders come in an aerosol spray form instead of a loose powder. Always use the spray form in a well-ventilated area, and be careful not to breathe it in.

Use a mild soap without any harsh ingredients like alcohol, dyes, or perfumes. These additives could irritate your skin and make your symptoms worse, especially while you’re using certain antifungal products. [8] X Research source Antifungal treatments work best on clean, dry skin, so wash and dry your feet right before applying your medication.
Use a separate towel for your feet so you don’t spread athlete’s foot to other parts of your body. Wash the towel after each use and don’t share it with anyone else. Let your feet air out after washing them until they are completely dry. Don’t put socks and shoes on your feet while they’re still damp! Medicated powders will also help soak up moisture and reduce irritation between your toes.

When the weather is warm enough, avoid wearing socks at all if you can. Instead, stick to wearing sandals when you need something on your feet.
Avoid shoes made of rubber or synthetic materials, which tend to trap moisture and can make your feet overheat. Stick to breathable materials, like canvas.
Remember to dry your feet thoroughly after soaking them!
Your doctor might prescribe an oral antifungal medication for stubborn athlete’s foot infections. If you have diabetes or another condition that affects your immune system, don’t wait—go see your doctor right away. Without treatment, you could develop more serious complications, like a secondary bacterial infection. You should also get your athlete’s foot checked out if you notice severe symptoms, such as swelling, worsening redness, fluids draining from the area, or a fever.
Use breathable cotton socks or moisture-wicking athletic socks to prevent excess sweating, and wear shoes made of light, breathable materials. If you’re prone to sweaty feet, try applying a medicated powder or some cornstarch to your feet after washing and drying them. The powder will soak up moisture throughout the day.
If you were recently infected, clean anything that came into contact with your feet thoroughly before you use it again. This will help you avoid reinfecting yourself or others.
Even if you’re not working out in a public area, it’s always a good idea to wash up after breaking a sweat.
You can also disinfect surfaces by spraying them with hydrogen peroxide. Simply spray it on, let it stand for a few minutes, then wipe it away with a clean cloth. [26] X Research source
