000,
Your expert opinion has been formed because you talked to somebody. Give me the reference that shows that the FAA approves the medications you indicated. You're dispensing advice about illegal actions (and unsafe actions) based on the fact that a doctor said it was okay. You didn't provide information, you provided an opinion which contains dangerous information.
How on earth can you determine that because a medication contains the same "active ingredient," it's acceptable to use? You're a chemist as well as a doctor, now?
You read labels. Good. You should. Where on the label do you find an authorization from the Administrator to take those medications while engaging in flight activities? Further, where do you find any statement, ANYWHERE, that authorizes the medication, rather than addressing the condition you're trying to hide with the medication? Can't find such an authorization? No surprise there; it doesn't exist. There's a good reason for it, too.
The FAA does not approve medications. Or conditions, except on an individual basis. Certain medications have general approval as being recognized for not having side effects in the general populace, however, blanket authorization is not given. Further, the FAA does not approve the use of those medications for any specific condition; while the med may not have harmful sideaffects, the condition may be debilitating or hazardous, thereby negating any implied approval for the medication itself. The bottom line? The med may certainly be taken, but the pilot still can't fly with the condition. Even if the medication isn't a barrier, the condition for which it is taken certainly may be.
If an aviator has a medical condition which does not meet the criteria for medical certification, or any known condition which is unsafe, then he or she may not fly, regardless of the medication taken.

The nasal sprays you advocate for an "emergency" won't clear your sinus; it may make you feel better, but it won't clear your sinus, or change your condition. It won't help you be safe, or protect you during a descent. You'll perhaps get some temporary relief from a runny nose, but nothing will open those sinuses, particularly not on the short term.
This does bring to mind the question of why you would be flying in a condition that might require the medication to begin with, and goes back to the prohibition of flying during times of medical deficiency.
You don't care about addition or safety, so you say. Quite obviously. The issue isn't addiction. It's impairment, which is the chief hazard of most nasal sprays on the market, and as indicated before, the cause of a number of accidents over the years. In order to relieve your perceived condition, but not the actual condition, you're fine with impairment. Good choice. (Even though it won't work, but good choice).
Do I think you're going to take ten sick days a year? I don't know you or your proclivities, but I can infer from your statement that you do intend to operate in an unsafe manner with medical deficiencies for ten days out of each year. Is that your point?
