Pseudoephedrine / triprolidine
"I have used for my multiple allergies and asthma pseudoephedrine and tripolidine since 1972. I have experienced on occasions prostate swelling, minor sleepiness, etc; however, its benefits far outweight its side effects. For several years I have used one 60mg/30mg tablet a day and it has managed my classic rhinitis. The combination pseudoephedrine-tripolidine has proven superior to all other combinations (I have tried them all) across the years. Now, it appears the med is drying up (pardon the pun), possibly from the meth freaks misuse and now we must all suffer for their predatorial rechemicalizations."
