DOSAGE AND ADMINISTRATION

Management of Diarrhea in Patients 13 Years of Age and Older

Lomotil is recommended as adjunctive therapy for the management of diarrhea in patients 13 years of age and older. Consider the nutritional status and degree of dehydration in patients prior to initiating therapy with Lomotil. The use of Lomotil should be accompanied by appropriate fluid and electrolyte therapy, when indicated. If severe dehydration or electrolyte imbalance is present, do not administer Lomotil until appropriate corrective therapy has been indicated (see WARNINGS).

Initial and Maximum Recommended Dosage in Patients 13 Years of Age and Older

The initial adult dosage is 2 Lomotil tablets four times daily (maximum total daily dose of 20 mg per day of diphenoxylate hydrochloride). Most patients will require this dosage until initial control of diarrhea has been achieved. Clinical improvement of acute diarrhea is usually observed within 48 hours.

Dosage after Initial Control of Diarrhea

After initial control has been achieved, the Lomotil dosage may be reduced to meet individual requirements. Control may often be maintained with as little as two Lomotil tablets daily.

Duration of Treatment

If clinical improvement of chronic diarrhea after treatment with the maximum recommended daily dosage is not observed within 10 days, discontinue Lomotil as symptoms are unlikely to be controlled by further administration.
