Sometimes they do, but often they tell the pharmacy that they can use the generic (and most folks seem to want generic). Occasionally, they insist on the brand, but this is more often because while most generics are the same, sometimes there are differences. Lithium, used as a mood stabilizer, is the example I can think of, but is far from the only one. More people want brand name for over the counter - like panodil/pinex - but sometimes this is because folks don't realize that the generic is the same drug.
