From the actual text, rather than the summary:

> The doctor picked up the phone and called San Francisco’s poison control center. No one at the center had ever heard of an accidental overdose this large—for Septra or any other antibiotic, for that matter—and nothing close had ever been reported in the medical literature. The toxicology expert there told the panicked clinicians that there wasn’t much they could do other than monitor the patient closely.

It's unfortunate (in the "safety rules are written in blood" manner), but now there's a datapoint that says a 38x overdose of Septra may be survivable, and what the effects can be.
