Hi all. We went to a physician who was a travel medicine specialist. He actually suggested using Neosynephrine at takeoff and just before landing on long flights. Perhaps you meant Neosynephrine, not Neosporine which is an antibiotic?
The Neosynephrine should not be the long acting kind, but the regular original version. It has been a godsend to me because I always got sinus infections from flights. Using this has made a huge difference for me and I'm so greatful to this physician.
