Bethanechol
About Bethanechol
Bethanechol is an oral prescription medication used to treat urinary retention, which is the inability to empty the bladder completely. It is commonly prescribed for individuals experiencing bladder emptying issues after surgery, after childbirth, or due to certain nerve-related bladder conditions. Bethanechol is not effective when urinary retention is caused by a physical blockage, such as an enlarged prostate (benign prostatic hyperplasia), urethral narrowing, or other mechanical obstructions of the urinary tract.
For the best results, this medication is typically taken several times a day at regular intervals. It is highly recommended to take Bethanechol on an empty stomach, either one hour before or two hours after a meal, to help prevent nausea or vomiting. Incorporating structured bladder training, such as urinating on a set schedule, can also help improve your overall results.
While using this medication, some people may experience mild side effects like sweating, flushing, or stomach cramps. However, you should contact your doctor or pharmacist immediately if you experience more serious issues, such as severe dizziness, wheezing, or a slow heartbeat.
Do not take this medication if you have certain health conditions, including asthma, active stomach ulcers, a slow heart rate, low blood pressure, or physical blockages in your stomach, intestines, or urinary tract. Always talk to your doctor or pharmacist about your complete medical history before starting treatment.
This medicine can interact with alcohol and other drugs, especially medications that affect your nervous system or blood pressure, which may lead to extreme dizziness or fainting. If you are pregnant, breastfeeding, or are an older adult, consult your doctor or pharmacist to discuss if this medication is safe for your specific situation.

Drug Interactions
Drug-Drug Interactions
- Blood pressure medications: Combining Bethanechol with drugs that lower blood pressure, especially ganglion blockers, can cause a severe and dangerous drop in blood pressure.
- Other cholinergic medicines: Taking this with other drugs that stimulate the nervous system can increase the risk of severe side effects like profound sweating, cramping, and slow heart rate.
- Antiarrhythmic drugs (e.g., Quinidine or procainamide): These heart medications can counteract the beneficial effects of Bethanechol on the bladder.
Drug-Food Interactions
- Food: Taking this medication with or immediately after food significantly increases the risk of severe nausea, vomiting, and abdominal discomfort.
Drug-Disease Interactions
