Diphenoxylate and atropine is a combination medicine used along with other measures to treat severe diarrhea in adults. Diphenoxylate helps stop diarrhea by slowing down the movements of the intestines.
Since diphenoxylate is chemically related to some narcotics, it may be habit-forming if taken in doses that are larger than prescribed. To help prevent possible abuse, atropine (an anticholinergic) has been added. If higher than normal doses of the combination are taken, the atropine will cause unpleasant effects, making it unlikely that such doses will be taken again.
Diphenoxylate and atropine combination medicine should not be used in children. Children with diarrhea should be given solutions of carbohydrates (sugars) and important salts (electrolytes) to replace the water, sugars, and important salts that are lost from the body during diarrhea. For more information on these solutions, see the Carbohydrates and Electrolytes (Systemic) monograph.
This medicine is available only with your doctor's prescription.

This medicine should not be used in children. Children, especially very young children, are very sensitive to the effects of diphenoxylate and atropine. This may increase the chance of side effects during treatment. Also, the fluid loss caused by diarrhea may result in a severe condition. For this reason, it is very important that a sufficient amount of liquids be given to replace the fluid lost by the body. If you have any questions about this, check with your health care professional.
Shortness of breath or difficulty in breathing may be especially likely to occur in elderly patients, who are usually more sensitive than younger adults to the effects of diphenoxylate. Also, the fluid loss caused by diarrhea may result in a severe condition. For this reason, elderly persons should not take this medicine without first checking with their doctor. It is also very important that a sufficient amount of liquids be taken to replace the fluid lost by the body. If you have any questions about this, check with your health care professional.
