Afrin's medication is oxymetazoline. It is not in the aspirin family. It is tricky stuff to be sure. It is only to be used for about 3 days maximum - according to my experience and doctor's instructions. When I was in the Air Force, I was talking someone who had experience with aircraft mishap investigations. The investigators would often find many bottles of Afrin in the flight bags. Those guys are/were addicted to the stuff.
The major problem with this med is that after the three days it starts having the opposite effect. It starts to cause extreme congestion and blockage. Then vicious cycle begins of overuse. It really is nasty. The one time I had half of a bottle squirted into my nasal passages - by a doctor - it was awful. I cannot remember which ran more, my eyes or nose. It is strong and effective; you just have to follow the rules - 3 days max.
