Israetel claims fixed-dose injection pens are used because many patients struggle with dose calculations

What was said

"Do you know why there's a pre-loaded pen now with no adjustment? This is [ __ ] terrifying. Such an enormous fraction of people who take prescription drugs are functionally innumemerate. They can't do mental math reliably."

While discussing injectable weight-loss drugs, Mike Israetel claimed that non-adjustable, pre-loaded pens are used because a sizeable share of patients are “functionally innumerate” and cannot reliably handle dose calculations. He said he based this view on conversations with doctors “off the record”, presenting it as a safety and usability issue rather than a technological limitation.
