Fiorinal #3 is actually a combination of four different ingredients: Butalbital, Caffeine, Aspirin, and Codeine.
Well looking at those two medications, I already see potential problems because butalbital, reserpine, and codeine all can produce CNS depressant properties. Then we add in the third medication Triaminic Expectorant DH, which is a combination, or was at that time, a combination, of Hydrocodone, phenylpropanolamine, pheniramine, Pyrilamine, and Guaifenesin.
