My pharmacist says manufacturers have stopped making the combination Pseudoephedrine and Triplodine that I have used for many, many years for allergies and asthma-related bronchial difficulties and at age 62, having tried the less effective and somewhat systemically depressing alternatives I would just as soon keep using what has worked since 1972. I do better with it. Prevalence of Triplodine seems to be the issue instead of the Pesudoepehedrine.
