Cab taking sleep aids containing dyphenhydramine hydrochloride have adverse effects and can it cause frequent urination?

Maybe: Diphenhydramine (benedryl) is not a sleep aid, but an antihistamine. If allergy therapy is warranted and the secondary drowsiness helps to take the edge off, then improved sleep may be achieved. However, some folks excrete benedryl more slowly, and drowsiness may extend through the next morning and be detrimental to alertness. Also, bladder dysfunction occurs in a few patients.

Too much sedation: Diphenhydramine is the cause of many home and work accidents. It can cause too much sedation and problems arise when one is trying to get to life after waking up. And, yes, most sleeping pills can affect the bladder, but this common drug, Diphenhydramine is one of them.
