Summary
Anticholinergic drugs can blunt pancreatic secretory response to secretin, so stimulation testing may give falsely abnormal, low results. This affects diagnostic accuracy, not patient safety.
What this interaction means in plain words
Flavoxate and Secretin can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
Antimuscarinic blockade opposes secretin-stimulated pancreatic secretion.
What to do
Stop flavoxate before secretin stimulation testing, allowing at least five half-lives, if clinically feasible.
What to ask your pharmacist
- Should I take them at different times of day?
- Does the dose of either medicine need to change?
- Is there anything I should avoid, such as alcohol or certain foods, while on both?
