Although mometasone furoate is generally well tolerated, skin reactions may occur. The most common adverse events of topical mometasone furoate were burning sensation, pruritus (itching), and skin atrophy or skin thinning. Signs of skin thinning (e.g., shininess of the skin, stretch marks, "spider veins" or enlarged blood vessels near skin surface) also occurred.
