Each package of “help I have a headache” contains 16 oblong pills. Each oblong pill contains 500mgs acetaminophen. Help remedies use's acetaminophen because it’s an excellent treatment for headaches and it’s delicate on stomachs. Help remedies use as large a dose of acetaminophen as they can, and the fewest possible fillers, coatings, and dyes.
They haven’t used “extra strength” to describe their headache pills even though they do have lots of acetaminophen. That’s because if everybody always used “extra strength” to describe headache pills then “extra strength” wouldn’t really mean anything anymore. And they don't want the things that they say to mean nothing.
