Fungicidal is defined as re biocidal chemical compounds or biological organisms used to kill fungi or fungal spores. Fungal infections such as ringworm, athlete’s foot, fungal nail infection, vaginal thrush, and some types of severe dandruff can be treated with antifungal medication. The main types of antifungal medications are topical antifungals, oral antifungals, intravenous antifungals, and intravaginal antifungal pessaries. Topical antifungals are applied directly to the skin, hair, or nails. Oral antifungals are swallowed in capsule, pill, or liquid form in order to treat internal fungal infections such as aspergillosis, a fungus that affects the lining of the lines, or fungal meningitis, a fungus that infects the protective membranes surrounding the brain and spinal cord. Intravenous antifungals are injected into the bloodstream, and intravaginal antifungal pessaries are small soft tablets that are inserted into the vagina to treat fungal infections such as vaginal thrush. Some of the most commonly used antifungal medicines include clotrimazole, econazole, miconazole, terbinafine, fluconazole, ketoconazole, and amphotericin. Some antifungal medicines can be used on children and babies. For example, miconazole oral gel can be used to treat oral thrush in babies.
