What the FDA labels say about taking them together

Aspirin/butalbital/caffeine and chlordiazepoxide

Aspirin/butalbital/caffeine's FDA label of December 2, 2024 names chlordiazepoxide in its drug interactions section; the chlordiazepoxide label PlainMeds reads does not name aspirin/butalbital/caffeine. The aspirin/butalbital/caffeine label: “Other narcotic analgesics, alcohol, general anesthetics, tranquilizers such as chlordiazepoxide, sedative-hypnotics, or other CNS depressants, causing increased CNS depression.”
