Inactive ingredients of diphenoxylate hydrochloride tablets include acacia, corn starch, magnesium stearate, sorbitol, sucrose, and talc. Chemical Structure Chemical Structure
Indications & Usage
Diphenoxylate hydrochloride is effective as adjunctive therapy in the management of diarrhea.
Dosage & Administration
DO NOT EXCEED RECOMMENDED DOSAGE. Adults The recommended initial dosage is two diphenoxylate hydrochloride tablets four times daily . Most patients will require this dosage until initial control has been achieved, after which the dosage may be reduced to meet individual requirements. Control may often be maintained with as little as 5 mg (two tablets) daily. Clinical improvement of acute diarrhea is usually observed within 48 hours. If clinical improvement of chronic diarrhea after treatment with a maximum daily dose of 20 mg of diphenoxylate hydrochloride is not observed within 10 days, symptoms are unlikely to be controlled by further administration. Children Diphenoxylate hydrochloride is not recommended in children under 2 years of age and should be used with special caution in young children (see Warnings and Precautions ). The nutritional status and degree of dehydration must be considered. Do not use diphenoxylate hydrochloride tablets for children under 13 years of age . KEEP THIS AND ALL MEDICATIONS OUT OF THE REACH OF CHILDREN.
Warnings & Precautions
WARNINGS DIPHENOXYLATE HYDROCHLORIDE IS NOT AN INNOCUOUS DRUG AND DOSAGE RECOMMENDATIONS SHOULD BE STRICTLY ADHERED TO, ESPECIALLY IN CHILDREN. DIPHENOXYLATE HYDROCHLORIDE IS NOT RECOMMENDED FOR CHILDREN UNDER 2 YEARS OF AGE. OVERDOSAGE MAY RESULT IN SEVERE RESPIRATORY DEPRESSION AND COMA, POSSIBLY LEADING TO PERMANENT BRAIN DAMAGE OR DEATH (SEE OVERDOSAGE ). THEREFORE, KEEP THIS MEDICATION OUT OF THE REACH OF CHILDREN. THE USE OF DIPHENOXYLATE HYDROCHLORIDE SHOULD BE ACCOMPANIED BY APPROPRIATE FLUID AND ELECTROLYTE THERAPY, WHEN INDICATED. IF SEVERE DEHYDRATION OR ELECTROLYTE IMBALANCE IS PRESENT, DIPHENOXYLATE HYDROCHLORIDE SHOULD BE WITHHELD UNTIL APPROPRIATE CORRECTIVE THERAPY HAS BEEN INITIATED. DRUG-INDUCED INHIBITION OF PERISTALSIS MAY RESULT IN FLUID RETENTION IN THE INTESTINE, WHICH MAY FURTHER AGGRAVATE DEHYDRATION AND ELECTROLYTE IMBALANCE. DIPHENOXYLATE HYDROCHLORIDE SHOULD BE USED WITH SPECIAL CAUTION IN YOUNG CHILDREN BECAUSE THIS AGE GROUP MAY BE PREDISPOSED TO DELAYED DIPHENOXYLATE TOXICITY AND BECAUSE OF THE GREATER VARIABILITY OF RESPONSE IN THIS AGE GROUP. Antiperistaltic agents may prolong and/or worsen diarrhea associated with organisms that penetrate the intestinal mucosa (toxigenic E. coli, Salmonella, Shigella), and pseudomembranous enterocolitis associated with broad-spectrum antibiotics. Antiperistaltic agents should not be used in these conditions. In some patients with acute ulcerative colitis, agents that inhibit intestinal motility or prolong intestinal transit time have been reported to induce toxic megacolon. Consequently, patients with acute ulcerative colitis should be carefully observed and diphenoxylate hydrochloride therapy should be discontinued promptly if abdominal distention occurs or if other untoward symptoms develop. Since the chemical structure of diphenoxylate hydrochloride is similar to that of meperidine hydrochloride, the concurrent use of diphenoxylate hydrochloride with monoamine oxidase (MAO) inhibitors may, in theory, precipitate hypertensive crisis. Diphenoxylate hydrochloride should be used with extreme caution in patients with advanced hepatorenal disease and in all patients with abnormal liver function since hepatic coma may be precipitated. Diphenoxylate hydrochloride may potentiate the action of barbiturates, tranquilizers, and alcohol. Therefore, the patient should be closely observed when any of these are used concomitantly.
Contraindications
Diphenoxylate hydrochloride is contraindicated in patients with: Known hypersensitivity to diphenoxylate or atropine. Obstructive jaundice. Diarrhea associated with pseudomembranous enterocolitis or enterotoxin-producing bacteria.
Adverse Reactions
At therapeutic doses, the following have been reported; they are listed in decreasing order of severity, but not of frequency: Nervous system: numbness of extremities, euphoria, depression, malaise/lethargy, confusion, sedation/drowsiness, dizziness, restlessness, headache. Allergic: anaphylaxis, angioneurotic edema, urticaria, swelling of the gums, pruritus. Gastrointestinal system: toxic megacolon, paralytic ileus, pancreatitis, vomiting, nausea, anorexia, abdominal discomfort. The following atropine sulfate effects are listed in decreasing order of severity, but not of frequency: hyperthermia, tachycardia, urinary retention, flushing, dryness of the skin and mucous membranes. These effects may occur, especially in children. THIS MEDICATION SHOULD BE KEPT IN A CHILD-RESISTANT CONTAINER AND OUT OF THE REACH OF CHILDREN SINCE AN OVERDOSAGE MAY RESULT IN SEVERE RESPIRATORY DEPRESSION AND COMA, POSSIBLY LEADING TO PERMANENT BRAIN DAMAGE OR DEATH.
Drug Interactions
Known drug interactions include barbiturates, tranquilizers, and alcohol. Diphenoxylate hydrochloride may interact with MAO inhibitors (see Warnings ). In studies with male rats, diphenoxylate hydrochloride was found to inhibit the hepatic microsomal enzyme system at a dose of 2 mg/kg/day. Therefore, diphenoxylate has the potential to prolong the biological half-lives of drugs for which the rate of elimination is dependent on the microsomal drug metabolizing enzyme system.
