Letter to Food and Drug Administration-
phenylpropanolamine- what other over the counter drug ingredient is equal to the effectiveness of Dristan Sinus for getting rid of sinus headaches. I have found over the years that Dristan sinus was the only drug that could relieve me of severe sinus headaches. Now with the removal of such drugs with phenylpropanolamine in them. I'm left with no know substitute that works!
