Heat rash is the medical term for prickly heat, which can be treated with glycerite lotion and glycerite menthol lotion. If prickly heat is accompanied by infection, it can be treated with antibiotic creams such as fusidic acid cream. If itching occurs, glucocorticoid creams such as hydrocortisone butyrate cream can be applied externally. Prickly heat is a superficial, inflammatory skin disease that occurs in the summer or in hot environments. It is one of the most common dermatologic diseases, and children and people who are exposed to high temperatures and humidity for long periods of time are more susceptible to infection. Prickly heat can be treated with topical medication, such as glycerite menthol lotion and glycerite lotion. Glycerite has the effect of astringent, anti-itching and anti-allergic, which is effective in the treatment of prickly heat. Do not scratch the prickly heat to avoid secondary bacterial infection. If accompanied by infection, antibiotic ointment should be applied externally, such as fusidic acid cream, mupirocin ointment, erythromycin ointment and so on. If the heat rash causes the patient to cause itching symptoms, glucocorticoid ointment can also be applied externally, such as hydrocortisone butyrate cream, trimethoprim cream and so on. Prickly heat patients should keep their skin dry and clean, and should not scratch vigorously. When treating prickly heat with medication, you should take targeted medication under the guidance of a professional doctor and use it according to the doctor’s instructions, avoiding blind use of medication.
