What is ketoconazole cream? What is nystatin?
Ketoconazole cream is an antifungal drug. It is in the same class of drugs as itraconazole (Sporanox), fluconazole (Diflucan), and miconazole (Micatin, Monistat). It prevents growth of several types of fungi by preventing production of the membranes that surround fungal cells. Ketoconazole cream is prescribed to treat fungal infections such as jock itch, athlete's foot, ringworm, dandruff, and tinea versicolor.
Nystatin is an oral antifungal medication used to treat intestinal candidiasis. Nystatin works by binding to sterols in the walls of fungal cells, disturbing the function of the cell wall. The fungal cells eventually lose their contents, leading to their death and improvement of the fungal infection.

Jock itch is an itchy red rash that appears in the groin area. The rash may be caused by a bacterial or fungal infection. People with diabetes and those who are obese are more susceptible to developing jock itch. Antifungal shampoos, creams, and pills may be needed to treat fungal jock itch. Bacterial jock itch may be treated with antibacterial soaps and topical and oral antibiotics.
Fungal nails (onychomycosis) may be caused by many species of fungi, but the most common is Trichophyton rubrum. Distal subungal onychomycosis starts as a discolored area at the nail's corner and slowly spread toward the cuticle. In proximal subungal onychomycosis, the infection starts at the cuticle and spreads toward the nail tip. Yeast onychomycosis is caused by Candida and may be the most common cause of fungal fingernail.
The term "ringworm" refers to a fungal infection on the surface of the skin. A physical examination of the affected skin, evaluation of skin scrapings under the microscope, and culture tests can help doctors make the appropriate distinctions. A proper diagnosis is essential to successful treatment. The different types of ringworm include the following: tinea barbae, tinea capitis, tinea corporis, tinea cruris, tinea faciei, tinea manus, tinea pedis, and tinea unguium.
Yeast Infection vs. Diaper Rash in Infants, Toddlers, and Children
Diaper rash in infants, babies, toddlers, and children is caused by Candida, the most common type of fungus. Signs and symptoms of diaper rash is red, elevated skin that may be visible under and in the creases of the skin, groin, or anus. Yeast diaper rash is not painful. Treatments for diaper rash include antibiotic creams, lotions, natural home remedies, over-the-counter (OTC) medicine, and oral antibiotics. Yeast infections in infants, babies, toddlers, and children can cause diaper rash, thrush. Signs and symptoms of thrush include thick, white lacy patches on top of a red base can form on the tongue, palate, or elsewhere inside the palate. Treatment for yeast infections caused by Candida fungi are similar to the treatments for diaper rash. If Candida gets into the blood stream of an individual they may get sick with or without a fever. If the Candida infection spreads throughout the body up to 45% of people may die. Even with common mouth thrush can cause critical illness and may be more resistant to normal treatment.
Dandruff (seborrhea) is a skin disorder that results from neither too much moisture nor too much oil. Dandruff can be treated with shampoos that contain tar, salicylic acid, zinc, selenium sulfide, or ketoconazole.
Tinea versicolor is a fungus infection that mainly affects the skin of young people. Recognized by light or reddish brown spots, and areas lighter than the surrounding skin. Tinea versicolor is caused by yeast actually found in our skin. Factors like heat, humidity, and sweat help it proliferate in people, resulting in a rash that is not contagious to others.
Is Jock Itch (Tinea Cruris) Contagious?
Jock itch is a fungal infection in the groin area that causes a raised, itchy, red rash. Jock itch can typically be treated with antifungal medications. People may need to seek medical care for jock itch if the groin area becomes swollen, tender, if red streaks appear, or if the lymph nodes become swollen.
