For a severe heat rash, your healthcare provider may prescribe medications to help relieve the pain and discomfort.
The most severe form of heat rash (miliaria pustulosa) has the potential to develop into a secondary infection. Notify your healthcare provider if you notice any of the following signs of infection:
- A rash only on one side or that is asymmetrical (not under both breasts or both armpits)
- White or light coloring over the red rash
- Flaking skin
- Pus oozing from the rash
- Blisters or boils
If your rash becomes infected, you may be prescribed oral or topical antibiotics.
