Thanks for the question. While Zilfone is not included in the search results, here are a couple options that may help with your sinus infection and allergic rhinitis: Sinus Relief Nasal spray at R169 contains paracetamol and may provide relief from sinus pain and pressure. Ceticit antihistamine tablets for R89.95 work well for allergy symptoms like a runny nose. They contain cetirizine which can reduce sneezing, itching and watery eyes. I hope one of these options provides you with some relief! Let me know if you need any other recommendations.
