I still do take 10 mg Bentyl (generic -dicyclomine) when I am going away from my house before around 9:30 AM. So not frequently since I am retired. It seems to quell bowel urgency after about 45 minutes to an hour. The side effects for me are mild…initially some imbalance, a little lightheadedness, but I can still walk and think fine.
It wears off after about 6 hours, may need another dose, if you need more help later.
Hope this helps.
