Nathan Whitfield reads drug labels the way other people read contracts: slowly, twice, and with real attention to the footnotes. As an internist and clinical pharmacologist on a hospital formulary committee, he has spent years deciding which warnings are theoretical and which ones put people in hospital beds, and that judgement is what he brings to the reader questions here.
His favourite questions are the unglamorous ones: why gabapentin has to be tapered rather than stopped, why steroids are so useful and so easy to misuse, why metformin is started low and slow, and why isotretinoin demands strict pregnancy prevention. He answers with mechanisms first, because a reader who understands the why keeps themselves safer than one who just memorises a rule.
He covers the metabolic, pain and skin corner of the site. He is strict about one point: pharmacology on a website is population-level knowledge, and readers are individuals. His replies end with a pointer to a prescriber whenever the honest answer depends on labs, doses, or the rest of a medication list he cannot see.
