Correct answer: E — Renal function monitoring is required during treatment

Mesalazine can rarely affect renal function, so renal monitoring is recommended at baseline and during treatment. Monitoring helps detect toxicity even when symptoms are absent. INR, lithium, and peak flow are not routine mesalazine monitoring tests.
