[|Human|] Hi doctor I have itchy throat and scartchy cough and I dont have any symptoms of cold like sneezing , head ache and runny or stuffed nose. But I feel like there is phlegm in my throat which neither I could spit or swallow. And one more thing,I suffer from sinusitis very often. I have 3 cough syrup in my hands 1) Dilosyn 2)Phensedyl 3) Reswas Could you please suggest me the right one among those three
[|AI|]  Hello, NONE of the three cough syrups you have inquired about are effective for your condition. You either have allergic rhinitis or rhinosinusitis that can be established with skin prick tests or blood test (specific IGE). If allergy results are negative, then your condition is non-allergic rhinitis. You need (1) oral antihistamines like cetirizine 10 mg or Exocet 5 mg plus (2) Flumast-AZ nasal spray that is a combination of fluticasone and elastane 2 sprays/nostril twice daily. This should be taken for a minimum of 2 months (max 3 months) and then stopped to see if the effect lasts. You can always restart if symptoms return. Hope that was useful. Best Wishes.
