Ketoconazole tablets are typically reserved for severe or "hard-to-treat" fungal infections: Systemic Fungal Infections: Blastomycosis, Coccidioidomycosis, and Histoplasmosis. Severe Skin Infections: Severe cases of Ringworm (Tinea Corporis), Athlete?s Foot (Tinea Pedis), or Jock Itch (Tinea Cruris) that don't respond to creams. Chronic Mucocutaneous Candidiasis: Persistent yeast infections of the skin, mouth, or throat. Cushing?s Syndrome: In specific medical cases, it is used off-label to reduce excess cortisol production by the adrenal glands.

Ketoconazole works by "poking holes" in the protective barrier of the fungus: Ergosterol Inhibition: Fungi need a substance called Ergosterol to build their cell membranes (their "skin"). The Blockade: Ketoconazole blocks the enzyme (CYP450) that creates ergosterol. Cell Death: Without a strong cell membrane, the internal contents of the fungal cell leak out, and the fungus dies, stopping the infection from spreading.

Nausea or Vomiting Liver Toxicity: Yellowing of eyes/skin (Jaundice). Stomach Pain Dark Urine: Or persistent fatigue. Headache Hormonal Changes: Decreased testosterone/libido. Dizziness Irregular Heartbeat: Or chest pain.
