Atomoxetine and methylene blue
Atomoxetine's FDA label (Strattera) of June 30, 2026 names methylene blue in its drug interactions section; the methylene blue label PlainMeds reads does not name atomoxetine. The atomoxetine label: “Prevention or Management; STRATTERA is contraindicated in patients taking MAOIs, including MAOIs such as linezolid or intravenous methylene blue, or in patients who stopped an MAOI within 14 days.”
