It is common for severe fungal infections to take two to four weeks to show significant improvement. Since you still have intense itching, your doctor might consider switching your oral antifungal to terbinafine or adjusting your itraconazole dosage. For topical relief, alternative creams like luliconazole or ketoconazole may be prescribed. To ease the itching immediately, an oral antihistamine like cetirizine can help. Please consult your prescribing doctor before changing your regimen. They can confirm if the infection is resistant or if a different diagnosis is present. Keep the affected areas dry, clean, and avoid sharing towels.
