It's hard to be pleasant and give 4x forms of ID when yer blinded by a sinus attack. Those pills are a miracle.
If you need help for sinus issues, there are two other options which our family has found to work VERY well with little or no side effect (personal experience here).
One is guaifenesin (Brand name of Mucinex). My allergist prescribes it for his patients with serious sinus issues at 1200 mg twice a day. Both he and a couple pharmacists have told me that it's a very old and very safe medicine with very few to no side effects.
We've found it to not leave you as spacey as pseudoephedrine. The generic is MUCH cheaper than the brand name, FWIW.
The other is a natural supplement called Fenugreek. It's a spice which also thins the mucous and two of those twice a day help clear congestion and as far we've been able to tell, with no side effects.
It's the best smelling herbal supplement I've ever encountered. It smells like maple syrup and when we researched it, discovered that it is actually used in making artificial maple syrup.
A friend told us that he tried both the mucinex and fenugreek and found terrific relief. He was right. I have never heard of any indications that you can't do both. It hasn't hurt us yet.
