About Bentyl
Overview
Bentyl contains dicyclomine, an antispasmodic and anticholinergic medicine. It is used to treat functional bowel disorders, including irritable bowel syndrome (IBS). It works by relieving muscle spasms in the digestive tract.
What it treats
Functional bowel disorders, including irritable bowel syndrome (IBS).
Safety information
Side effects
Common side effects include dizziness, dry mouth, blurred vision, nausea, sleepiness, weakness and nervousness. Contact a doctor promptly for serious side effects involving the heart or nervous system, including worsening of an existing heart condition, severe confusion or loss of touch with reality. Reduced sweating can cause fever and heat stroke, which require urgent medical attention. Other serious risks include difficulty passing urine, particularly in people with an enlarged prostate, and toxic megacolon, a dangerous enlargement of the colon, particularly in people with ulcerative colitis or Salmonella dysentery. Diarrhea may be an early sign of a partial bowel blockage, especially in people with an ileostomy or colostomy; contact a doctor promptly, as treatment in this situation may be dangerous or fatal. Older adults may be more susceptible to side effects.
When to call your doctor
If symptoms are severe or getting worse quickly, seek emergency care rather than waiting.
Before taking this medicine
Do not take dicyclomine if you are breastfeeding or have glaucoma, myasthenia gravis, a blockage of the urinary tract or digestive tract, severe ulcerative colitis, reflux esophagitis (inflammation of the esophagus caused by reflux), or an unstable heart or circulation condition during acute bleeding. It must not be given to infants younger than 6 months. Use requires caution in people with cardiovascular conditions, ulcerative colitis, an enlarged prostate, or impaired liver or kidney function. It may worsen cardiovascular conditions, cause difficulty passing urine, or contribute to serious bowel complications. People with Salmonella dysentery are at risk of toxic megacolon, a serious enlargement of the colon. Diarrhea can be an early sign of a partial bowel blockage, particularly in people with an ileostomy or colostomy; treatment in this situation may be dangerous or fatal. Dicyclomine can reduce sweating and cause heat exhaustion or heat stroke. Psychosis and delirium have been reported, particularly in older people and people with mental illness who are sensitive to anticholinergic medicines. Older adults may be more susceptible to adverse effects. During pregnancy, use only if clearly needed. Safety and effectiveness in children have not been established.
Interactions
Tell your doctor if you take medicines for glaucoma, other anticholinergic medicines or antacids. Dicyclomine may counteract glaucoma medicines and increase pressure inside the eye. It may also increase certain effects or side effects of other anticholinergic medicines and affect how various medicines are absorbed from the digestive tract. Antacids can interfere with the absorption of dicyclomine.
