Motofen® is not an innocuous drug and dosage recommendations should be strictly adhered to.
Accidental overdose may result in severe respiratory depression and coma, possibly leading to permanent
brain damage or death.
The use of Motofen® does not preclude the administration of appropriate fluid and electrolyte therapy.
Dehydration, particularly in children, may further influence the variability of response to Motofen®
and may predispose to delayed difenoxin intoxication. Drug-induced inhibition of peristalsis may result
in fluid retention in the colon, and this may further aggravate dehydration and electrolyte imbalance.
Use with caution in patients with ulcerative colitis or liver or kidney disease.
Motofen® may produce drowsiness or dizziness. Use caution when engaging in activities
requiring mental alertness, such as driving or operating dangerous machinery.
Safety and effectiveness in children below the age of 12 have not been established.
