Image: 4 panels organized in a rectangle following a sequential order like a comic strip. The first panel is of a man with a very serious face stating, "Hey man, got any diphenhydramine?" The second panel is a grainy picture of the actor Tony Stark with a slightly inquisitive face and saying, "What's that?" The third panel is an identical copy of the first image and saying, "Benadryl the allergy medicine." The fourth and final panel is a grainy picture of Tony Stark rolling his eyes and taking a deep breath.
Medicine schools in anywhere except USA. Farmacists, medics, nurses, life rescuers, hospitals, social workers. They're all encouraged to use the active components of medicines and not commercial brand names. Specially because there are differences in regulations and sometimes the commercial names don't carry the same formulation in other markets, or are US specific. Tylenol for example doesn't exist in Latin America. But you can find many other brands and presentations of paracetamol as acetaminophen.
Of course Tylenol exists in LatAm! At least in Brazil it does..but we buy paracetamol because its cheaper
