Summary
Dulaglutide delays gastric emptying, which could in theory slow absorption of oral drugs. Prazosin is not a narrow therapeutic index drug and no clinically meaningful interaction is expected.
What this interaction means in plain words
Dulaglutide and Prazosin have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Dulaglutide belongs to Endocrine; Prazosin belongs to Genitourinary.
Why it happens
Delayed gastric emptying from GLP-1 receptor activation may slightly slow oral drug absorption; no specific interaction is established.
What to do
No dose change is needed. Watch for first-dose-type hypotension if prazosin is started while the patient has reduced intake or nausea.
