Summary
Both drugs block muscarinic receptors, so using them together can add to anticholinergic effects such as dry mouth, constipation, urinary retention, blurred vision and heat intolerance. Systemic absorption from the topical product is limited, so the effect is usually modest, but it can be more noticeable in older or susceptible patients.
