###Human: Does Paracetamol allergy cause itchy rashes on face, and stomach in a 6-year-old? ###Assistant: Hello. For allergy, you can give Cetirizine syrup. Paracetamol is one of the safest drugs. It is very rare that Paracetamol causes allergy. And you are also giving Paracetamol for the last three years, and there was no allergy. Generally, allergies increase by repeated exposures. So I think it may be due to some food allergy or infection. At present do not give Paracetamol if you feel that it is causing allergy, continue with Ibuprofen. If she is developing so much rash, itching or breathing problem then go to a pediatrician as soon as possible. Food allergy. Syrup Cetirizine 5 ml BD (twice a day) for five days.
