(2) Insist on correct medication Many drugs can treat tinea corporis, but some patients can't be cured after replacing various drugs, mainly because of improper methods. External use of drugs to treat tinea is simple and easy, but it must be applied 2 ~ 3 times a day, and the scope of application should be slightly larger than the area of skin lesions. Even if the rash subsides and itching is not obvious, it must be persisted for a period of time. Never fish for three days and dry the net for two days, just like mowing the grass without removing the roots. Although the illness can be temporarily relieved, you will be tall again in the spring breeze when you meet the right conditions.
(3) Avoid using corticosteroid ointment, that is to say, hormone drugs cannot be used externally. Corticosteroid ointment such as Fusong ointment, Dexamethasone ointment, Betamethasone ointment and some traditional Chinese medicine ointment containing hormones can be used for a variety of allergic skin diseases, such as eczema, contact dermatitis, neurodermatitis and so on, with good results. But tinea corporis is caused by fungi. Hormones can not kill fungi, but can promote their growth and reproduction, making tinea disease develop faster and more seriously. Therefore, external drugs should not be abused at will.
(4) Active treatment of systemic diseases If tinea corporis is caused by a systemic disease and the body's resistance is low, it should be actively treated to enhance resistance. If tinea corporis is caused by long-term use of corticosteroids or immunosuppressants, these drugs should be used as little as possible or not when conditions permit.
(5) When the condition is serious, such as tinea corporis and rash is widely distributed, oral antifungal drugs, such as griseofulvin and ketoconazole, can be combined. However, these drugs have certain side effects, such as liver and kidney damage, so they should be taken under the guidance of a doctor, and liver function should be checked regularly during treatment.
