For treating cholinergic urticaria, several approaches can be taken. Avoid triggers such as heat, stress, and exercise that can bring on an attack. Take antihistamines as prescribed by a doctor to relieve symptoms. Cool compresses can help soothe the itchy rash. Wearing loose-fitting clothing and staying in a cool environment can also be beneficial. Stress management techniques like meditation and deep breathing exercises may help reduce the frequency of outbreaks. If the condition is severe and unresponsive to these measures, a dermatologist may recommend additional treatments such as immunotherapy or alternative medications. Regular follow-ups with the doctor are important to monitor the condition and adjust the treatment plan as needed.
