Over-the-counter treatments for toe fungus include using water-diluted vinegar foot soaks and vaporizing rubs that include menthol, camphor and eucalyptus, according to Dr. Marvin Lipman with Consumer Reports. Supplements such as acetic acid; tea tree, lavender and lemongrass essential oils; and jojoba oils may also help to treat toe fungus.
Mild toe fungus infections can also be treated with over-the-counter, anti-fungal topical creams and salves, according to WebMD.
Toe fungus that includes infection within the nail can be treated with nail lacquer painted on the nail daily and then wiped off with alcohol, according to Dr. Andrew Weil. Serious infections may require prescription oral anti-fungal medications such as Lamisil or removal of an infected nail. Preventative measures include keeping toenails trimmed short, wearing absorbent socks, discarding old shoes that may contain fungus and allowing the feet to dry thoroughly after swimming, baths or showers.
Toe fungus presents a yellowish, greenish or gray discoloration of the toenails, according to Dr. Lipman. In extreme cases, toenails may be difficult to cut or become crumbly in appearance. When treatment for toe fungus is necessary due to pain or for cosmetic reasons, it is commonly used to prevent bacterial infections, especially in patients with diabetes.
