It is a synthetic benzylamine antifungal, which works by preventing the growth of fungus by interrupting the formation of the fungal cell membrane.
This medicine is marketed under the trade names Butop and Mentax, plus, it is the main ingredient in a cream called – Lotrimin Ultra.
It is usually used for the topical treatment of tinea pedis (athlete’s foot), tinea versicolor (pityriasis versicolor), Tinea cruris (jock itch), and tinea corporis (ringworm).
Tinea infections are superficial yeast infections typically caused by the three genera of dermatophytes: Microsporum, Trichophyton, and Epidermophyton.
Symptoms of tinea infections depend on the affected area of the body and may include the following:
- Jock itch – it causes an itchy, burning rash in the groin area.
- Athlete’s foot – it causes burning, itching, and cracked skin between the toes.
- Scalp ringworm – it causes itchy, red patches on the head. It typically affects children. It can leave bald spots.
- Ringworm (a worm doesn’t cause it) – it is a red skin rash which forms a ring around normal-looking skin.
To treat athlete’s foot, apply the ointment two times per day for 7 days or one time per day for 4 weeks.
To treat ringworm (also referred to as dermatophytosis) apply 2 times per day for 14 days. Individuals with tinea versicolor should apply a dose of this antifungal once per day for 14 days.
This cream works best if it is used at the same time(s) every day.

You only need to put a thin layer of this medicine on the area where you need it.
It belongs to a type of medications called antifungals that are used to treat various skin infections caused by yeast or fungus.
This antifungal works by creating a disruption in the production of ergosterol that, ultimately, leads to the occurrence of holes in the fungal cell membrane.
It comes in a topical cream, a topical solution, and a lozenge form.
It is found under the brand name of Canesten.
It is usually used for the local treatment of:
- vaginal yeast infections (common symptoms include – a thick, creamy white, odorless vaginal discharge as well as soreness, itching, and redness around the outside of the vagina). Absorption of this antifungal after a vaginal application is estimated to be between 3 percent and 10 percent.
- oropharyngeal candidiasis (overgrows of Candida albicans in the mouth and throat);
- fungal infections of the skin (like – athlete’s foot, ringworm, and jock itch).
This ointment should be applied evenly and thinly to the affected area 2 – 3 times per day.
If you are using this cream to treat tinea pedis, make sure you wash and dry the feet properly, particularly between the toes, before using this medicine.
If the skin infection does not improve within 14 days for athlete’s foot, 7 days for ringworm or jock itch, check with your healthcare provider as the diagnosis should be reviewed.

Butenafine Hydrochloride vs Clotrimazole – Which Is Better For Yeast Infections Of The Skin?
Butenafine Hydrochloride is a synthetic benzylamine derivative with fungicidal properties.
It works by inhibiting the synthesis of sterols by inhibiting an enzyme responsible for the creation of sterols needed in fungal cell membranes, called squalene epoxidase.
Clotrimazole (brand name – Canesten) is an antifungal medication that is used to treat yeast infections of the mouth, vagina, and skin, like – jock itch, athlete’s foot, and body ringworm.
This antifungal works by killing the fungus which causes the infection.
A 2005 randomized, double-blind trial at the Department of Dermatology & STD, Delhi, India, 80 patients diagnosed clinically to have localized tinea corporis or tinea cruris treated with these two medicines, at the end of 1 week, had a higher clinical cure with butenafine compared with clotrimazole study participants.
Nevertheless, the difference was not significant at 4 and 8 weeks of treatment.
