Take oral medication. The most effective way to get rid of nail fungus is systemic treatment with oral prescription antifungals. Treatment with oral medications can take 2-3 months or longer. Oral antifungal prescription medications include Lamisil, which is usually prescribed with a dose of 250 mg a day for 12 weeks. Side effects can include rash, diarrhea, or liver enzyme abnormalities. This medication should not be used if you have liver or kidney issues.

Before buying new shoes, have a professional measure the length and width of your feet at the end of the day, while you're standing. For unusually flat feet or high arches, an exam by a podiatrist may be warranted. These conditions can increase the risk of osteoarthritis. Early treatment and use of proper footwear may help to avoid unnecessary wear and tear on the joints of the foot.
Yeast onychomycosis: This type is caused by a yeast called Candida and not by the Trichophyton fungus named above. It is more common in fingernails and is a common cause of fungal fingernails. Patients may have associated paronychia (infection of the cuticle). Candida can cause yellow, brown, white, or thickened nails. Some people who have this infection also have yeast in their mouth or have a chronic paronychia (see above) that is also infected with yeast.

You might cringe at the thought of having a fungal or yeast infection. The concept might feel icky. The reality, however, is that many types of fungi live on the skin all the time, even though you can't see them. Most of the time, these fungi don't cause any problems, but sometimes a fungus will change and cause an infection. These are some of the more common fungal and yeast infections that people experience.
There are many topical antifungal drugs useful in the treatment of athlete's foot including: miconazole nitrate, clotrimazole, tolnaftate (a synthetic thiocarbamate), terbinafine hydrochloride,[17] butenafine hydrochloride and undecylenic acid. The fungal infection may be treated with topical antifungal agents, which can take the form of a spray, powder, cream, or gel. Topical application of an antifungal cream such as terbinafine once daily for one week or butenafine once daily for two weeks is effective in most cases of athlete's foot and is more effective than application of miconazole or clotrimazole.[23] Plantar-type athlete's foot is more resistant to topical treatments due to the presence of thickened hyperkeratotic skin on the sole of the foot.[13] Keratolytic and humectant medications such as urea, salicyclic acid (Whitfield's ointment), and lactic acid are useful adjunct medications and improve penetration of antifungal agents into the thickened skin.[13] Topical glucocorticoids are sometimes prescribed to alleviate inflammation and itching associated with the infection.[13]

White superficial onychomycosis (WSO) is caused by fungal invasion of the superficial layers of the nail plate to form "white islands" on the plate. It accounts for around 10 percent of onychomycosis cases. In some cases, WSO is a misdiagnosis of "keratin granulations" which are not a fungus, but a reaction to nail polish that can cause the nails to have a chalky white appearance. A laboratory test should be performed to confirm.[15]
Candida albicans is a common yeast that grows inside the human body. In healthy people, other bacteria and immune cells keep this yeast under control so it doesn’t cause any problems, but in some people candida can become overgrown and cause infections in various areas. One of the ways candida shows up is through the skin where it can cause noticeable reactions or infections. Other ways are on the mouth, vagina and anus.

Ciclopirox (Penlac) topical solution 8% is a medical nail lacquer that has been approved to treat finger or toenail fungus that does not involve the white portion of the nail (lunula) in people with normal immune systems. In one study, ciclopirox got rid of the fungus 22% of the time. The medication is applied to affected nails once daily for up to one year. The lacquer must be wiped clean with alcohol once a week.


Toenail fungus, also called onychomycosis, is a common fungal infection of your toenail. The most noticeable symptom is a white, brown, or yellow discoloration of one or more of your toenails. It may spread and cause the nails to thicken or crack. Sandal season or not, toenail fungus typically isn’t what you want to see when you look at your feet. Luckily there are many treatments you can try.
