Mometasone furoate should not be used on the skin for more than 2 weeks. Mometasone furoate is a glucocorticoid drug with anti-inflammatory and anti-allergic effects, which can be used in the treatment of contact dermatitis, neurodermatitis, eczema, psoriasis and many other skin diseases. Topical application of mometasone furoate cream for skin diseases should not exceed a maximum of 2 weeks. Long-term use of hormonal drugs can lead to thinning of the skin, increased sensitivity and susceptibility to skin diseases such as contact dermatitis and eczema. Usually, regulated use of hormone drugs can have good therapeutic effects, but prolonged use of large doses of hormones may lead to bacterial infections, skin atrophy and many other side effects, so patients must use and stop the drugs under the guidance of a doctor.
