Brands like Tylenol, Tempra, and Biogesic are drugs containing an active ingredient of Paracetamol.

Paracetamol, also known as acetaminophen, is a medication used to treat fever and mild to moderate pain. At a standard dose, paracetamol only slightly decreases body temperature; it is inferior to ibuprofen in that respect, and the benefits of its use for fever are unclear. Paracetamol may relieve pain in acute mild migraines but only slightly in episodic tension headaches.

Therefore to conclude, Acetaminophen, Paracetamol, and Tylenol(Brand) are all the same and as indicated clinically, it gives both analgesia (pain relief)and antipyretic (anti-fever) effect.
