If you want to stop the itching of prickly heat, you can take measures such as general treatment, topical medication and oral medication to alleviate the symptoms. 1. General treatment: In summer, ventilation and heat dissipation should be carried out, loose and breathable clothes should be worn to keep the skin clean and dry. Trim baby’s nails to avoid scratching and causing the rash to break out. 2. Topical medication: Topical medication is based on the principle of coolness, astringency and itching relief, and can be used as topical glycerin lotion and prickly heat powder, and pus rash can be used as topical 2% ichthyol glycerin lotion and Huanglian pumpernickel powder. 3. Oral medication: antihistamine can be taken orally if the itching is obvious, and antibiotics can be taken orally if the infection of prickly heat is serious; traditional Chinese medicines (e.g. honeysuckle) can also be taken to clear heat, detoxify and relieve dampness. It is recommended to take the child to the hospital for further examination, and all medications need to be used under the guidance of a professional doctor.
