Treatment for Miliaria
The primary treatment for miliaria is keeping the affected areas cool, well-ventilated, and dry to promote remission of this self-limiting condition. 1
Understanding Miliaria
Miliaria (heat rash) is a self-limiting cutaneous disorder that occurs due to blockage of eccrine sweat ducts and retention of sweat. It typically presents as:
- Clear fluid-filled vesicles on the skin surface in miliaria crystallina 1
- Small sweat-filled vesicles (1-3 mm) in the epidermis 2
- In some cases, it can progress to more extensive bullous lesions 2
Causes and Risk Factors
Miliaria develops from:
- Exposure to humid climates 2
- Skin occlusion 2
- Raised temperatures and heat retention 3
- Persistent febrile states 4
- Certain medications (documented cases with doxorubicin, idarubicin, isotretinoin, and bethanechol) 4, 5
- Prolonged wearing of certain fabrics, particularly flame-resistant clothing in hot environments 3
Treatment Approach
First-line Management:
- Remove the precipitating factors by keeping affected areas cool and dry 1
- Ensure good ventilation to the affected skin 1
- Regular changing of clothing, especially in hot environments 3
- Maintain good personal hygiene to keep skin as dry and clean as possible 3
For Clothing-Related Miliaria:
- Thoroughly launder blend fabrics to remove detergent residue 3
- Consider temporary removal of exposure to certain fabric types as recovery may take a week or longer 3
For Complicated Cases:
- Monitor for superimposed bacterial infections, particularly Staphylococcus 3
- Topical skin treatments may be necessary for moderate to severe cases 3
Special Considerations
- Miliaria is common in infants and children but can occur in adults, particularly in hot environments or during febrile illnesses 1
- Patients with sensitive skin should take extra precautions in hot environments 3
- Early reporting of skin irritation or rash to healthcare providers is important to initiate necessary medical procedures 3
Recovery Timeline
- Miliaria crystallina is typically self-limited 1, 5
- Resolution can occur within 3 days without complications in some cases 5
- More extensive cases may take a week or longer to clear 3
