Interactions

Antacids: Decrease absorption of propantheline if given together. Drugs with anticholinergic effects (eg, antihistamines, antiparkinson drugs, tricyclic antidepressants): Additive peripheral anticholinergic side effects. Haloperidol: May cause decreased serum haloperidol levels, worsened schizophrenic symptoms and tardive dyskinesia. Phenothiazines: May decrease antipsychotic effectiveness of phenothiazines; may produce additive anticholinergic effects.

Diarrhea: May be symptom of incomplete intestinal obstruction, especially in patients with ileostomy or colostomy. Treatment of diarrhea with drug is inappropriate and possibly harmful. Gastric ulcer: May delay gastric emptying rate and complicate therapy. Heat prostration: Can occur in presence of high environmental temperature.

PATIENT CARE CONSIDERATIONS

• Administer antacids 1 hr before or after propantheline.
• Administer 30 min before meals and at bedtime (³ 2 hr after last meal) unless otherwise directed.
• Store at room temperature in tight container.

 

Assessment/Interventions

• Obtain patient history, including drug history and any known allergies.

Patient/Family Education

• Advise patient to take drug 30 min before meals and at bedtime unless directed otherwise by physician.
• Instruct patient not to chew or crush tablets.
