How to use urea cream for toenail fungus

Make sure the nail changes are fungal

A thick, yellow or crumbly nail can be fungal, but nail injuries and nail psoriasis can look similar. A clinician can examine the nail and test a clipping or scraping before choosing treatment. Urea can soften a nail without resolving whatever caused the thickening, so easier trimming is not the same as a cleared infection.13

How to apply urea cream

1. 1Confirm the strength and purpose. For thick nail softening, a dermatologist can prescribe 40% urea cream or ointment. Ask whether the plan is to thin the nail or remove affected nail before starting an antifungal lacquer.
2. 2Wash your feet and dry them carefully, including between your toes. Keeping feet clean and dry is part of fungal infection care.
3. 3Apply the urea directly to the hard nail surface as directed. A general nail thickening regimen uses 40% urea nightly under a covering, called occlusion. Use that approach only when it matches your clinician's instructions, and ask what covering to use.
4. 4Have very thick nails reduced by a podiatrist if necessary. If you are shown how to file the nail between visits, follow that technique rather than trying to remove the whole affected nail yourself.
5. 5Use the antifungal on its own prescribed schedule. Ask how to fit the two applications together rather than assuming they should be layered at the same time.

Keep the urea directions and antifungal schedule together, because a toenail routine should not require its own filing cabinet. Continue the antifungal for the prescribed course, even when the nail starts looking better.1

Does urea cream help toenail fungus?

Yes, as a supporting treatment: softening thick nails can improve results from antifungal medication applied to the nail. Urea treatment can also help remove affected nail before lacquer therapy. The antifungal treats the infection; urea helps deal with the thick nail that makes treatment harder. Ordinary creams and ointments bought without a prescription usually do not clear nail fungus. Terbinafine cream intended for athlete's foot cannot penetrate the nail adequately to treat a nail infection.145

How long does it take?

There is no fixed softening deadline for every thick nail, and urea does not always thin nails successfully. Clearing the fungal infection and growing a clear nail are separate milestones. Treatment commonly lasts months, and replacing the affected toenail can take up to a year or longer. Discolouration can remain while the old nail grows out, even after the fungus has cleared. Some nails retain changes in appearance after successful treatment.123

When should you get medical help?

Get treatment guidance before attempting home nail removal if you have diabetes, poor circulation, a weakened immune system or reduced sensation in your feet. A podiatrist is also the safer option if you cannot reach your nails. Seek medical care if the surrounding skin becomes red, swollen, hot, painful or starts draining fluid or pus, or if walking hurts. Arrange a review if the infection spreads or treatment is not helping. Tell your clinician about prescriptions and supplements, and whether you are pregnant, planning pregnancy or breastfeeding, because those details affect which antifungal treatments are suitable.1267

Keep nail care tools separate

Give nail care tools their own place in the bathroom, rather than letting the shelf become a lending library. Do not share clippers or trimmers, sanitize them before use, and use disposable emery boards instead of reusable files. Change socks daily and alternate footwear to help reduce reinfection.345
