Linzess Administration and Efficacy

Recommended Dosing and Administration

• The American Gastroenterological Association recommends an alternative dose of 72 mcg once daily for CIC patients based on individual presentation or tolerability concerns 1
• Linzess must be taken on an empty stomach at least 30 minutes before the first meal of the day, as taking it with food significantly reduces efficacy, according to the Gastroenterology society 1

Safety Considerations

• Diarrhea is the most common adverse effect, occurring in 10-20% of patients, leading to discontinuation in approximately 4.5-5.7% of cases, as reported by the Gastroenterology society 1
• The Gastroenterology society states that Linzess is absolutely contraindicated in patients with known or suspected mechanical gastrointestinal obstruction 1

Clinical Context and Evidence

• The 290 mcg dose approved for IBS-C can also be considered for CIC patients, recognizing that these conditions overlap and are often indistinguishable in clinical practice, according to the Gastroenterology society 1
• The Gastroenterology society notes that the most common reasons for discontinuation over the first year are loss of efficacy and insurance coverage barriers, not adverse events 1
