Suggest An Alternative To Wal-phed D Sinus And Allergy

I have been using the pseudophedrine cold remedies. For me they do a far superior job at reducing cold symptoms without side effects. I was using wal-phed D sinus & allergy, but it wasn't at the branch of Walgreens near my office. Has this drug been discontinued? Will they have it back again? The other drug I was given instead isn't as effective despite what the moody lady in the store said.
