Treatments and drugs

By Mayo Clinic Staff

Avoiding overheating may be all you need to do for mild heat rash. Once skin is cool, heat rash tends to clear quickly.


More-severe forms of heat rash may require ointments you apply to your skin to relieve discomfort and prevent complications. Such topical treatments may include:

  • Calamine lotion to soothe itching
  • Anhydrous lanolin, which may help prevent duct blockage and stop new lesions from forming
  • Topical steroids in the most serious cases
