<s>[INST] Hi Doc,For the past five years flying long distances has been a nightmare. Two hours into the flight I start sneezing, followed by itching nostrils, then uncontrollable running nose. I go through this ordeal throughout the flight so you can imagine when it is a 10hr flight. When I get to my destination I am down for about a day or two again. I have tried Claritin, clarinase but nothing seems to work. Can you please advise? I have a long flight to take next week and I am already scared. [/INST] Hellos you mentioned you started sneezing, itching nostrils, running nose. All these symptoms may be due to allergic rhinitis. Usually clarity czarinas don't act in these symptoms because these symptoms were due to allergy so antibiotics don't work. When such type of patient visit I prescribe montelukast+ fexofenadine once or twice in day depending on symptoms. You can also take saline nasal Chat Doctor. Steam inhalation and hot coffee also helps. For instant relief you can take one tablet of deflazacort 30 mg (but not mote than one tablet in any condition). Hope this will help you. </s>
