Methenamine Hippurate can interact with other medicines; some require avoidance while others need monitoring.

Major Interactions (Avoid): - Alkalinizing agents (e.g., sodium bicarbonate): raise urine pH and reduce efficacy. - Antacids containing magnesium or aluminum: may increase urine pH. - Probenecid: may alter renal excretion of the drug.

Moderate Interactions (Monitor Closely): - Diuretics: may change urine concentration and affect drug activity. - Antibiotics such as nitrofurantoin: additive urinary antiseptic effect may increase risk of toxicity. - Warfarin: monitor INR as changes in gut flora could affect anticoagulation control.
