Bethanechol chloride (Urecholine) can be harmful to patients who have a urinary tract obstruction or bladder wall weakness. The medication has the ability to contract the bladder, causing pressure to build up in the urinary tract. In these patients, an increase in urinary tract pressure could cause the bladder to rupture.
What is Urinary retention?
The inability to completely empty the bladder is referred to as urinary retention. The onset can be abrupt or gradual.
Symptoms of sudden onset include inability to urinate and lower abdominal pain.
When symptoms appear gradually, they may include loss of bladder control, mild lower abdominal pain, and a weak urine stream.
If there is an obstruction or stricture (narrowing) in or around the bladder, or if the muscles in or around the bladder are weak, urine may be retained. Urinary retention can also be caused by certain types and locations of tumors, certain medications, being dehydrated, or having constipation.
