Hi plinko. Tylenol has two active ingredients, acetaminaphen
and pseudoaphedrine, along with an antihistamine. The acetaminaphen is not addictive, and pseudoephedrine by itself is not considered addictive either- and antihistimines are not physically addictive, contrary to what some allergy sufferers may believe.
Ambien, on the other hand, definitely poses a risk for addiction.
