Heat rash, generally referred to as prickly heat, can be treated using general treatment and medication. 1. General treatment: It is recommended to keep the lesion area cool and dry. The body can be cooled down by using a fan or air conditioner. Wear loose, breathable cotton clothing whenever possible. Use cold items such as wet cloths and ice packs to apply ice to the lesion area to help stop the itching or relieve pain. 2. Medications: The following medications are recommended for use under medical supervision. Topical glycerine lotion or prickly heat powder can be used topically to cool and relieve itching. Topical glucocorticoid creams, such as hydrocortisone, can also be used to reduce itching and speed up the inflammation. If the itching is obvious, oral antihistamines, such as loratadine, can be taken. Patients with heat rash are advised to go to the hospital, use medication under the guidance of the doctor and timely treatment.
