Pharmacologic class: Chloride channel activator
Therapeutic class: GI motility enhancer
Pregnancy risk category C
Enhances chloride-rich intestinal fluid secretion without altering sodium and potassium serum concentrations; increases intestinal fluid secretion and intestinal motility, which promotes stool passage and relieves symptoms of chronic idiopathic constipation
Soft gelatin capsules: 8 mcg, 24 mcg
Indications and dosages
➣ Chronic idiopathic constipation
Adults: 24 mcg P.O. twice daily
➣ Treatment of irritable bowel syndrome with constipation in women
Adults ages 18 and older: 8 mcg P.O. b.i.d.

Chronic Idiopathic Constipation and Opioid-Induced Constipation
Hepatic ImpairmentOral (Adults) Moderate hepatic impairment (Child-Pugh Class B)-16 mcg twice daily; if patient tolerates, can titrate to 24 mcg twice daily, if needed; Severe hepatic impairment (Child-Pugh Class C)-8 mcg twice daily; if patient tolerates, can titrate to 24 mcg twice daily, if needed.

- Assess for abdominal distention, presence of bowel sounds, and usual bowel patterns prior to and periodically during therapy.
- Assess color, consistency, and amount of stool produced.
- Lab Test Considerations: Assess women of childbearing age for pregnancy. Begin therapy following a negative pregnancy test.
Potential Nursing DiagnosesConstipation (Indications)
Diarrhea (Adverse Reactions)
- Patients with symptoms suggestive of mechanical GI obstruction should be evaluated prior to initiating therapy.
- Oral: Administer with food and water to decrease nausea. Swallow capsules whole; do not crush, break or chew.
- Do not administer to patients severe diarrhea.
- Instruct patient to take lubiprostone as directed.
- Inform patient that dyspnea may occur within 1 hr of first dose; usually resolves within 3 hrs, but may return with repeat doses.
- Advise patients that lubiprostone may cause diarrhea. Advise patient to notify health care professional if diarrhea becomes severe.
- May cause dizziness. Caution patient to avoid driving or other activities requiring alertness until response to medication is known.
- Advise female patients that a negative pregnancy test should be determined prior to taking lubiprostone and to use effective contraception during therapy. Notify health care professional if pregnancy is planned or suspected or if breastfeeding.
- Decrease in symptoms of chronic constipation. Need for continued therapy should be assessed periodically.
