Uses For Motofen
Difenoxin and atropine combination medicine is used along with other measures to treat severe diarrhea in adults. Difenoxin helps stop diarrhea by slowing down the movements of the intestines.
Since difenoxin 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.
Difenoxin and atropine combination medicine should not be used in children. Children with diarrhea should be given solutions of carbohydrates (sugars) and electrolytes (important salts) to replace the water and important salts that are lost from the body during diarrhea.
This medicine is available only with your doctor's prescription.
Before Using Motofen

This medicine should not be used in children. Children, especially very young children, are very sensitive to the effects of difenoxin 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.

If you have any questions about this, check with your health care professional.
Shortness of breath or difficulty in breathing may be more likely to occur in elderly patients, who are usually more sensitive than younger adults to the effects of difenoxin. 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.
