- Topical creams and ointments: These may be used to reduce inflammation, itchiness, and other symptoms. Examples include corticosteroids, antihistamines, and antimicrobial agents.
- Oral medications: In some cases, oral medications may be recommended to treat the underlying cause of the rash or to manage symptoms. Examples include antihistamines, antibiotics, and antifungal medications.
- Phototherapy: This treatment involves exposing the skin to controlled amounts of ultraviolet light to help reduce inflammation and other symptoms.
- Cold compresses: Applying cold compresses to the affected area can help reduce inflammation and soothe the skin.

- Stress management: Reducing stress through relaxation techniques, such as deep breathing or meditation, may help prevent the development of some types of skin rashes.
It is important to follow the treatment plan recommended by your healthcare provider in order to manage the rash effectively. If the rash is not improving or is worsening, it is important to consult with a healthcare provider for further evaluation and treatment.
