Lots of versions of Alka Seltzer use aspirin instead of acetaminophen, and aspirin in combination with phenylephrine is documented to reduce congestion more than either alone.

Note - avoid the cold & flu versions (the ones with orange bottoms) and the day & night versions (orange and green bottoms), because they're not aspirin, they're acetaminophen. The traditional blue bottom "Alka Seltzer Severe Cold" is the one with aspirin and phenylephrine.
