Hi, thanks for your question, I have read it and understand your concerns. Answer: Generally it is not recommended to take the two medications together as this can lead to increased sedation, disturbed alertness, respiratory depression etc. The risk is not high but better be safe. For the time being, please find other ways to relieve cold and flu symptoms. Take Paracetamol for sore throat and fever and use steam inhalation (with or without vicks) for nasal stuffiness and congestion. You can also try saline water drops in your nose. Hope this helps. Please feel free to ask for any further clarification.
