I have throat pain and mild dry cough. can i take combliflam and cetrizine together to cure it without complications?

Do you mean without: Harm? Well, combiflam is a pain killer, ibuprofen/acetaminophen combination, and cetirizine is an antihistaminic, either might work to relief pain/runny nose, if it is a mild viral URI, it might clear on its own anyway, if it doesn't or gets worse in few days, see a doctor, use saline nasal wash and salt water gargles as well, good luck
