[/INST] Hello, Thank you for asking at Chat Doctor. I went through your mothers-in-law history and would like to make suggestions for her as follows:1. As she has already taken 2 antihistamines, please consult a doctor before taking further dose of antihistamine.2. I would suggest her to take tablet montelukast.3. I would also suggest her to apply calamine lotion over the area with rash.4. Furthermore, I would suggest her not to scratch the itchy area as it would aggravate itching. Hope above suggestions will be helpful to her. Should you have any further query, please feel free to ask at Chat Doctor. Wish your mother-in-law the best of the health ahead. Thank you & Regards. </s>
