Dettol soap is effective against a wide range of microbes, including bacteria, yeast, and mildew. However, it is not specifically formulated as an antifungal. While it can kill some fungal organisms, it is not a substitute for prescribed antifungal medications for treating fungal infections like tinea versicolor or ringworm.
For effective treatment of fungal infections, consult a healthcare professional and follow their recommendations for topical or oral antifungal medications.
