Anti Fungal

What Are Anti-Fungal Medications?

Anti-fungal medications are drugs used to treat fungal infections in various parts of the body, including the skin, nails, scalp, mouth, and internal organs. Fungal infections are caused by fungi (yeasts, molds, and dermatophytes) that thrive in warm, moist environments.

​

• Anti-fungal medications help with:

  • Eliminating or controlling fungal growth

  • Relieving symptoms like itching, redness, and inflammation

  • Preventing the spread of infection

  • Treating chronic or recurring fungal conditions
