Quadriderm cream contains Betamethasone, which is a strong steroid. While it might temporarily soothe itching, using a steroid cream alone on ringworm (a fungal infection) is not recommended because it can make the infection worse and cause it to spread. For ringworm and underarm itching, you need an antifungal medication instead. Safe and effective generic options include clotrimazole, miconazole, or terbinafine creams, which are available over the counter. I recommend stopping the steroid cream and consulting a healthcare provider or pharmacist to confirm your diagnosis and start the appropriate antifungal treatment.
