Hi Howard,
Benadryl has anticholinergic side effects. In  theory it can potentially affect urine flow and mental status. These effects are dose dependent and also depend on the general health, size, and renal function of the person taking the drug. Every person is unique. If you are healthier and can tolerate what you are taking without ill effect, good on you.
Thank you for using Allexperts,
